ACTION:
Interim final rule.
SUMMARY: The Food and Drug
Administration (FDA) is amending the
health claim regulation entitled
‘‘Soluble fiber from certain foods and
risk of coronary heart disease (CHD)’’ to
add barley betafiber as an additional
eligible source of beta-glucan soluble
fiber. Barley betafiber is the ethanol
precipitated soluble fraction of cellulase
and alpha-amylase hydrolyzed whole

grain barley flour. FDA is taking this
action in response to a health claim
petition submitted by Cargill, Inc. FDA
previously concluded that there was
significant scientific agreement that a
claim characterizing the relationship
between beta-glucan soluble fiber of
certain whole oat and whole grain
barley products and CHD risk is
supported by the totality of publicly
available scientific evidence. Based on
the totality of publicly available
scientific evidence, FDA now has
concluded that in addition to certain
whole oat and whole grain barley
products, barley betafiber is also an
appropriate source of beta-glucan
soluble fiber. Therefore, FDA is
amending the health claim regulation
entitled ‘‘Soluble fiber from certain
foods and risk of CHD’’ to include
barley betafiber as another eligible
source of beta-glucan soluble fiber.
This interim final rule is
effective February 25, 2008. Submit

SUPPLEMENTARY INFORMATION:

I. Background
A. The Nutrition Labeling and
Education Act of 1990
The Nutrition Labeling and Education
Act of 1990 (the 1990 amendments)
(Public Law 101–535) amended the
Federal Food, Drug, and Cosmetic Act
(the act) in a number of important ways.
One aspect of the 1990 amendments was
that they clarified FDA’s authority to
regulate health claims on food labels
and in food labeling.
FDA (we) issued several new
regulations in 1993 that implemented
the health claim provisions of the 1990
amendments. Among these were 21 CFR
101.14, Health claims: general
requirements (58 FR 2478, January 6,
1993) and § 101.70 (21 CFR 101.70),
Petitions for health claims (58 FR 2478),
which set out the general requirements
for the authorization and use of health
claims and established a process for
petitioning the agency to authorize
health claims about substance-disease
relationships and set out the types of
information that any such petition must
include. These regulations became
effective on May 8, 1993.
When implementing the 1990
amendments, FDA also conducted a
review of evidence for a relationship
between dietary fiber and
cardiovascular disease (CVD). Based on
this review, the agency concluded that
the available scientific evidence did not
justify authorization of a health claim
relating dietary fiber to reduced risk of
CVD (58 FR 2552, January 6, 1993)
(1993 dietary fiber and CVD health
claim final rule). However, FDA did
VerDate Aug<31>2005
14:21 Feb 22, 2008
Jkt 214001
conclude there was significant scientific
agreement that the totality of publicly
available scientific evidence supported
an association between types of foods
that are low in saturated fat and
cholesterol and that naturally are good
sources of soluble dietary fiber (i.e.,
fruits, vegetables, and grain products)
and reduced risk of CHD1. Therefore,
FDA authorized a health claim about the
relationship between diets low in
saturated fat and cholesterol and high in
vegetables, fruit, and grain products that
contain soluble fiber and a reduced risk
of CHD (21 CFR 101.77; 58 FR 2552 at
2572). In the 1993 dietary fiber and CVD
health claim final rule, FDA commented
that if a manufacturer could document
with appropriate evidence that
consumption of the type of soluble fiber
in a particular food has the effect of
lowering blood low density lipoprotein
(LDL) cholesterol, and has no adverse
effects on other heart disease risk factors
(e.g., high density lipoprotein
cholesterol), it should petition for
authorization of a health claim specific
for that particular dietary fibercontaining food (58 FR 2552 at 2567).
B. Soluble Fiber from Certain Foods and
Risk of CHD Health Claim (21 CFR
101.81)
In 1995, FDA received a petition for
a health claim on the relationship
between oat bran and rolled oats and
reduced risk of CHD. FDA concluded
there was significant scientific
agreement that the totality of publicly
available scientific evidence supported
the relationship between consumption
of whole oat products and reduced risk
of CHD. FDA further concluded that the
type of soluble fiber found in whole
oats, i.e., beta-glucan soluble fiber, is the
component primarily responsible for the
hypocholesterolemic effects associated
with consumption of whole oat foods as
part of a diet that is low in saturated fat
and cholesterol (62 FR 3584 at 3597 and
3598, January 23, 1997). As such, the
final rule authorized a health claim
relating the consumption of beta-glucan
soluble fiber in whole oat foods, as part
of a diet low in saturated fat and
cholesterol, and reduced risk of CHD
(the 1997 oat beta-glucan health claim
final rule). The source of beta-glucan
soluble fiber in foods bearing this health
claim had to be one of three eligible
whole oat products; i.e., oat bran, rolled
oats, or whole oat flour (see
§ 101.81(c)(2)(ii)(A)). In the 1997 oat
beta-glucan health claim final rule, FDA

anticipated the likelihood that other
sources and types of soluble fibers could
also affect blood lipid levels, and thus,
may reduce heart disease risk (62 FR
3584 at 3587). At that time, FDA
considered structuring the final rule as
an umbrella regulation authorizing the
use of a claim for ‘‘soluble fiber from
certain foods‘‘ and risk of CHD. Such
action would have allowed flexibility in
expanding the claim to other specific
food sources of soluble fiber when
consumption of those foods has been
demonstrated to help reduce the risk of
heart disease. However, the agency
concluded that it was premature to do
so because FDA had not reviewed the
totality of evidence on other, non-whole
oat sources of soluble fiber (62 FR 3584
at 3588).
The agency amended § 101.81 (21
CFR 101.81), in response to a health
claim petition to add a health claim
relating soluble fiber from psyllium seed
husk and CHD risk (63 FR 8103,
February 18, 1998). At this time, FDA
also modified the heading in § 101.81
from ‘‘* * * Soluble fiber from whole
oats and risk of coronary heart disease’’
to ‘‘* * * Soluble fiber from certain
foods and risk of coronary heart disease
(CHD)’’ (63 FR 8103). FDA has also
amended § 101.81, in response to health
claim petitions, to include oatrim,
whole grain barley, and certain dry
milled barley grain products as eligible
sources of beta-glucan soluble fiber. In
2002, FDA amended § 101.81 to add
oatrim, which is the soluble fraction of
alpha-amylase hydrolyzed oat bran or
whole oat flour, as an eligible source of
beta-glucan soluble fiber (67 FR 61733,
October 2, 2002), and finally, FDA
amended § 101.81 to add whole grain
barley and certain dry milled barley
grain products as eligible sources of
beta-glucan soluble fiber in 2005 (70 FR
76150, December 23, 2005).
II. Petition and Grounds
A. The Petition
Cargill, Inc. (petitioner), submitted a
health claim petition to FDA on June 20,
2006, under section 403(r)(4) of the act
(21 U.S.C. 343(r)(4)). The petition
requested that the agency expand the
‘‘Soluble fiber from certain foods and
risk of coronary heart disease health
claim’’ (§ 101.81) to include ‘‘barley
betafiber’’ (described in section II.B of
this document) as an eligible food
ingredient source of beta-glucan soluble
fiber in addition to the oat and whole
grain and dry milled barley ingredients
now listed (Ref. 1). On September 28,
2006, the agency notified the petitioner
that it had completed its initial review
of the petition and that the petition was

25FER1
9940
Federal Register / Vol. 73, No. 37 / Monday, February 25, 2008 / Rules and Regulations
rfrederick on PROD1PC67 with RULES
being filed for further action in
accordance with section 403(r)(4) of the
act. If the agency does not act, by either
denying the petition or issuing a
proposed regulation to authorize the
health claim, within 90 days of the date
of filing for further action, the petition
is deemed to be denied unless an
extension is mutually agreed upon by
the agency and the petitioner (section
403(r)(4)(A)(i) of the act and
§ 101.70(j)(3)(iii)). The petitioner and
FDA subsequently mutually agreed to
extend the deadline for the agency’s
decision on the petition to March 6,
2008. The petitioner also requested that
FDA issue an interim final rule by
which labeling of foods that contain
‘‘barley betafiber’’ in appropriate
amounts could bear the health claim
prior to publication of a final rule.
B. Nature of the Substance
The substance that is the subject of
the oat/barley portion of current
§ 101.81 is beta-glucan soluble fiber
from the specific oat and barley food
products listed in § 101.81(c)(2)(ii)(A).
Current § 101.81(c)(2)(ii)(A) has been
amended twice previously to list
additional oat or barley food products as
eligible sources (67 FR 61773 and 70 FR
76150). Similar to these previous
actions, FDA is now, in response to
Cargill’s health claim petition,
amending § 101.81(c)(2)(ii)(A) to list
barley betafiber as an eligible source of
barley beta-glucan soluble fiber.
The petition states that barley
betafiber is a concentrated barley betaglucan soluble fiber product derived
from whole barley flour. The
petitioner’s description of the barley
betafiber manufacturing process reflects
information contained in the
petitioner’s patent entitled ‘‘Improved
Dietary Fiber Containing Materials
Comprising Low Molecular Weight
Glucan’’ (World Intellectual Property
Organization, International Publication
Number WO 2004/086878 A2) (Ref. 2)
and a report of an expert panel on the
generally recognized as safe (GRAS)
status of barley betafiber commissioned
by the petitioner (Ref. 3). The patent and
the GRAS status report provide
information on multiple variations of
procedures for manufacturing
concentrated barley beta-glucan soluble
fiber products; these procedures differ
from the manufacturing procedures for
producing the unique barley betafiber
substance that is the subject of the
petition. Further, the clinical trial
reported in the petition tested two
different barley beta-glucan soluble fiber
concentrates—a high molecular weight
concentrate and a low molecular weight
concentrate. The petitioner specified
VerDate Aug<31>2005
14:21 Feb 22, 2008
Jkt 214001
that the barley betafiber product, which
is the subject of the petition, is only the
low molecular weight concentrate
studied in the clinical trial (Ref. 4). FDA
was not satisfied that the information in
the petition was sufficiently specific in
describing the manufacturing process
for the unique barley betafiber product
for which there is scientific evidence to
permit a showing that the product is
comparable in cholesterol-lowering
ability to the other oat and barley food
products listed in current
§ 101.81(c)(2)(ii)(A). Discussion between
the agency and the petitioner resulted in
the description of the barley betafiber
manufacturing process presented in the
following paragraph and in final
§ 101.81(c)(2)(ii)(A)(6) (Refs. 2 through
5).
Barley betafiber is produced from an
aqueous slurry of whole grain barley
flour, starting with addition of an
exogenous grain liquefying enzyme
preparation with cellulase and alphaamylase activity, derived from Bacillus
amyloliquefaciens. The cellulase
activity of the enzyme preparation acts
on the beta-glucan soluble fiber in
barley flour, since beta-glucan is a type
of cellulose, and the alpha-amylase
activity of the enzyme preparation acts
on the starch in the barley flour. The
temperature of the slurry is kept at or
above the gelatinization temperature of
the barley starch but below cellulase
enzyme inactivation temperature; i.e.,
about 65° C, for about 30 to 60 minutes,
to facilitate a partial hydrolysis of both
the beta-glucan soluble fiber and starch.
The pH of the slurry is kept in the range
of about 5 to 7. When the cellulase
enzymatic hydrolysis of barley flour has
modified the beta-glucan soluble fiber to
the desired extent, the cellulase activity
of the enzyme preparation is heat
inactivated. After the cellulase activity
of the enzyme preparation has been
deactivated, an exogenous thermo-stable
amylolytic enzyme is added to the
barley flour slurry for continued
hydrolysis of starch molecules at the
higher temperature. The slurry is held at
the higher temperature until
substantially all the starch has been
hydrolyzed. A clear aqueous extract,
which contains barley betafiber and the
sugars and dextrins resulting from
substantial hydrolysis of starch is then
separated from insoluble material by
centrifugation. Barley betafiber is
precipitated from the aqueous extract
supernatant with ethanol to separate it
from other soluble components (i.e.,
substantially hydrolyzed starch, protein,
lipids and other minor components) that
remain suspended in the aqueous
extract supernatant. The resultant barley
PO 00000
Frm 00006
Fmt 4700
Sfmt 4700
betafiber precipitate is then dried and
milled. The molecular weight range of
barley betafiber produced by this
procedure is 120 to 400 kilodaltons
(Refs. 2, 3, and 5). The molecular weight
range of barley betafiber is substantially
reduced from that of native barley betaglucan soluble fiber. The molecular
weight range of native barley betaglucan soluble fiber has been reported to
range from about 500 to 3,330
kilodaltons depending upon the
cultivars and applied extraction
procedures, although lower molecular
weight values of 80 to 300 kilodaltons
have also been reported (Ref. 1). In final
§ 101.81(c)(2)(ii)(A)(6), FDA defines
barley betafiber by its manufacturing
process, as follows ‘‘Barley betafiber.
Barley betafiber is the ethanol
precipitated soluble fraction of cellulase
and alpha-amylase hydrolyzed whole
grain barley. Barley betafiber is
produced by hydrolysis of whole grain
barley flour, as defined in paragraph
(c)(2)(ii)(A)(5) of this section, with a
cellulase and alpha-amylase enzyme
preparation, to produce a clear aqueous
extract that contains mainly partially
hydrolyzed beta-glucan and
substantially hydrolyzed starch. The
soluble, partially hydrolyzed betaglucan is separated from the insoluble
material by centrifugation, and after
removal of the insoluble material, the
partially hydrolyzed beta-glucan soluble
fiber is separated from the other soluble
compounds by precipitation with
ethanol. The product is then dried,
milled and sifted. Barley betafiber shall
have a beta-glucan soluble fiber content
of at least 70 percent on a dry weight
basis.’’
C. Review of Preliminary Requirements
for a Health Claim
1. The Substance Is Associated With a
Disease for Which the U.S. Population
Is at Risk
CHD continues to be a disease that
has a large impact on mortality and
morbidity in the general adult U.S.
population. As explained in the existing
beta-glucan soluble fiber health claim
(§ 101.81(b)), FDA recognizes the CHD
risk reduction benefit of certain foods
that are sources of soluble dietary fiber
resulting from effects on lowering blood
total and LDL cholesterol. Although ageadjusted CHD mortality rates in the
United States had been steadily
decreasing since approximately 1960,
recent evidence has suggested that the
decline in CHD mortality has slowed
(Ref. 6). Heart disease has been
recognized as the leading cause of death
in the United States for at least the last
50 years (Ref. 6). Based on these facts,
E:\FR\FM\25FER1.SGM
25FER1
Federal Register / Vol. 73, No. 37 / Monday, February 25, 2008 / Rules and Regulations
FDA concludes that, as required in
§ 101.14(b)(1), CHD is a disease for
which the U.S. population is at risk.
rfrederick on PROD1PC67 with RULES
2. The Substance Is a Food
The substance of the health claim is
beta-glucan soluble fiber from listed oat
and barley sources. The petitioner
requests an amendment to add barley
betafiber to the list of eligible sources of
beta-glucan soluble fiber. Barley
betafiber is derived from whole barley
flour. Barley flour is a commonly
consumed human food and beta-glucan
soluble fiber is a nutrient component of
this food. Thus, the beta-glucan soluble
fiber from barley betafiber, a processed
whole barley flour product, is a
‘‘substance’’ as defined in § 101.14(a)(2).
Health claim general requirements
provide that where a substance is to be
consumed at ‘‘other than decreased
dietary levels,’’ the substance must
contribute taste, aroma, nutritive value,
or any other technical effect as listed in
21 CFR 170.3(o), and must retain that
attribute when consumed at levels
necessary to justify the claim
(§ 101.14(b)(3)(i)). The level necessary to
justify the claim is 0.75 g beta-glucan
soluble fiber per serving. The term
‘‘nutritive value’’ is defined in
§ 101.14(a)(3) as ‘‘a value in sustaining
human existence by such processes as
promoting growth, replacing lost
essential nutrients, or providing
energy.’’ The petitioner provided several
examples of food categories (bars,
beverages, bread, breakfast cereals,
cookies, crackers, instant rice, pasta,
muffins, salad dressings, snack chips,
soups, tortillas and taco shells,
vegetarian patties/crumbles, and
reduced fat yogurt) in which barley
betafiber could be used as an ingredient
at a maximum level of 3 grams (g) betaglucan soluble fiber per serving. Betaglucan soluble fiber at 0.75 to 3 g per
serving contributes nutritive value
because it provides a source of calories
and soluble fiber. In addition to its role
as a source of beta-glucan soluble fiber,
barley betafiber also has technical
effects, including food applications as a
thickener (e.g., soups), texturizer (e.g.,
snack foods), humectant (e.g., retain
moisture of tortillas), or fat replacer
(e.g., dressings for salads). Therefore,
FDA concludes that the preliminary
requirement of § 101.14(b)(3)(i) is
satisfied.
3. The Substance Is Safe and Lawful
Section 101.14(b)(3)(ii) requires that
the substance be a food or a food
ingredient or a component of a food
ingredient whose use at the levels
necessary to justify a claim has been
demonstrated by the proponent of the
VerDate Aug<31>2005
14:21 Feb 22, 2008
Jkt 214001
claim, to FDA’s satisfaction, to be safe
and lawful under the applicable food
safety provisions of the act. The
petitioner asserts that the use of barley
betafiber as a food ingredient is GRAS.
The petitioner included in its health
claim petition documentation of its
2003 GRAS self-determination for barley
betafiber, which contains 70 percent or
more pure barley beta-glucan soluble
fiber as evidence that barley betafiber
meets the safe and lawful requirement
(Ref. 3). FDA also received a notice
informing FDA that the petitioner
determined, through scientific
procedures, that the use of barley
betafiber is GRAS. FDA issued a letter
(Ref. 7) in response to this notice stating
that the agency had no questions at the
time regarding petitioner’s conclusions
that barley betafiber is GRAS under the
intended conditions of use.
The 2003 Cargill GRAS selfdetermination stipulates that barley
betafiber is obtained from food-grade
whole grain barley flour by water
extraction at elevated temperature,
while starch is removed during the
extraction process by treatment with
enzymes that are GRAS for use in food
manufacturing processes, specifically
alpha-amylases from Bacillus
licheniformis and B. amyloliquefaciens.
The extracted barley betafiber is
recovered by precipitation with
denatured ethanol suitable for food
production, and contains 70 percent or
more beta-glucan, 2 to 12 percent
protein, and less than 3 percent of each
sugars, lipids, and inorganic salts. The
basis of the safety determination relies
on the fact that barley betafiber contains
only native components of barley and is
formed by the action of applied foodgrade enzymes, residues, or processing
aids.
In addition, barley is a traditional
food with a long history of safe use,
since at least 8,000 B.C. based on
archeological discoveries (Ref. 3). In the
Maghreb countries of Morocco, Algeria,
Libya, and Tunisia, barley is used in a
variety of traditional foods (bread, soup,
porridge), resulting in an average intake
of up to 172 g per person per day
(Morocco). With this intake of barley,
about 6 g per person per day of pure
beta-glucan soluble fiber is consumed.
The preparation of these traditional
foods involves baking or boiling for
longer periods of time, which ensures
extraction of beta-glucan from its
natural context (cell walls, complexes
with proteoglycans). The physiological
properties of beta-glucan as a dietary
fiber may, therefore, be found in these
traditional foods as is intended to be
achieved with the addition to processed
foods of barley beta-glucan concentrate.

The intended uses of barley betafiber
listed as a food ingredient stated in the
2003 Cargill GRAS self-determination
include the following food categories:
Bars, beverages, bread (whole grain and
specialty), breakfast cereals (ready to eat
and cooked), cookies (lite), crackers
(reduced fat), instant rice, macaroni
products, muffins (reduced fat), salad
dressings (lite), snack chips (reduced
fat), soups, tortillas and taco shells,
vegetarian patties/crumbles, and
reduced fat yogurt. The maximum
incorporation rate for each of these food
applications is 3 g beta-glucan soluble
fiber from barley betafiber per serving.
FDA concludes that the petitioners
have satisfied the preliminary
requirement of § 101.14(b)(3)(ii) to
demonstrate, to FDA’s satisfaction, that
the use of beta-glucan soluble fiber from
barley betafiber at levels necessary to
justify the health claim is safe and
lawful under the applicable food safety
provisions of the act. The agency has
not made its own determination
regarding the GRAS status of barley
betafiber or beta-glucan soluble fiber
from barley betafiber. Furthermore, the
agency notes that a regulation to
authorize a health claim for a substance
should not be interpreted as affirmation
that the substance is GRAS.
III. Review of Scientific Evidence of the
Substance-Disease Relationship
A. Basis for Evaluating the Relationship
Between Beta-Glucan Soluble Fiber from
Barley Betafiber and CHD
The types of data that FDA has
recognized in previous CHD health
claim evaluations as useful for assessing
CHD risk reduction are: Coronary events
(myocardial infarction, ischemia),
cardiovascular death, atherosclerosis,
high blood pressure, serum total
cholesterol, and serum LDL cholesterol.
FDA considers high blood pressure,
serum total cholesterol, and serum LDL
cholesterol levels to be the only
currently validated surrogate measures
for CHD risk (Ref. 8). Elevated levels of
serum total and LDL cholesterol, a
prerequisite for atherosclerotic disease,
is a major modifiable risk factor in the
development of CHD (Ref. 8). For these
reasons, the agency based its original
evaluation of the relationship between
oat beta-glucan soluble fiber and CHD
risk (62 FR 3584) and subsequent
evaluations to add oatrim (67 FR 61773)
and barley as eligible sources of betaglucan soluble fiber (70 FR 76150) in the
health claim, primarily on evidence for
serum total and LDL cholesterollowering effects of beta-glucan soluble
fiber containing food ingredients. As
such, our evaluation of the evidence

25FER1
rfrederick on PROD1PC67 with RULES
9942
Federal Register / Vol. 73, No. 37 / Monday, February 25, 2008 / Rules and Regulations
supporting the petitioned request to
extend the eligible barley sources to
include barley betafiber (as described in
section II.B of this preamble), focused
on evidence from human randomized
controlled trials of the effects of
consuming beta-glucan soluble fiber
from barley betafiber on blood lipids.
This focus is consistent with existing
§ 101.81 in which FDA concluded that
there is significant scientific agreement
that the relationship between CHD risk
and consumption of beta-glucan soluble
fiber from certain oat and barley food
ingredients is mediated primarily by the
effect of the beta-glucan soluble fiber on
serum lipids.
FDA’s determination of significant
scientific agreement that the totality of
publicly available scientific evidence
supports the relationship between betaglucan soluble fiber from certain oat and
barley foods and CHD risk is
documented in rulemaking for § 101.81.
When issuing the 1997 oat beta-glucan
health claim final rule, the agency
concluded that the beta-glucan soluble
fiber component of oat products plays a
significant role in the relationship
between whole grain oats and the risk
of CHD based, in part, on evidence that
there is a dose response between the
level of beta-glucan soluble fiber from
whole oats and the level of reduction in
serum LDL cholesterol, and evidence
that intakes at or above 3 g per day were
more effective in lowering serum lipids
than lower intake levels (62 FR 3584 at
3585). In the 2002 and 2005
amendments to the health claim to add
oatrim and whole grain and dry milled
barley products, respectively, as eligible
sources of beta-glucan soluble fiber, the
agency considered evidence that betaglucan soluble fiber from those sources
had comparable cholesterol-lowering
effects to that from the sources
previously listed in § 101.81(c)(2)(ii)(A)
as further support for FDA’s previous
determination that there is significant
scientific agreement that a relationship
exists between consumption of certain
beta-glucan soluble fiber sources and
reduced risk of CHD (67 FR 61773 at
61779 and 70 FR 76150 at 76155).
Similarly, FDA considers that scientific
evidence to establish that the
cholesterol-lowering effects of betaglucan soluble fiber from barley
betafiber are comparable to the effects of
beta-glucan soluble fiber from the oat/
barley products in current
§ 101.81(c)(2)(ii)(A) builds on the
substantial base of scientific evidence
that already establishes significant
scientific agreement for the association
between consumption of the oat/barley
products now listed and reduced risk of

CHD. FDA’s review of the evidence to
support the petitioned amendment of
the health claim regulation entitled
‘‘Soluble fiber from certain foods and
risk of CHD’’ was conducted consistent
with FDA published guidance on
significant scientific agreement in the
review of health claims (Ref. 9) and
focused on evidence from intervention
studies.
B. Assessment of Intervention Studies
This petition identified one relevant
human randomized controlled trial of
how consumption of beta-glucan soluble
fiber from barley betafiber affects heart
disease risk and serum lipid levels. A
summary of this trial was included in
the petition and subsequently published
in a peer reviewed scientific journal
(Ref. 4). FDA also evaluated reported
results from randomized controlled
trials of other types of beta-glucan
concentrates, extracts, and gums (Refs.
10 through 19).
The study reported in Keenan et al.
2007 (Ref. 4) investigated the effects of
consuming concentrated barley betaglucan soluble fiber-enriched foods
(fruit drink and corn flakes) on blood
lipids in hypercholesterolemic men and
women. The study was conducted as a
randomized, double-blind, placebocontrolled, parallel arm study of five
groups with 30 to 32 subjects per group.
The study included a total of 155
hypercholesterolemic adult subjects,
between 25 and 73 years of age, with
baseline serum LDL cholesterol levels
between 140 and 190 milligrams per
deciliter (mg/dL). The subjects were
instructed to follow a diet low in
saturated and trans fatty acids (less than
10 percent kilocalories (kcals) per day)
and to consume three servings of the
concentrated barley beta-glucan soluble
fiber-enriched test foods per day, one
serving with each of three major meals.
The concentrated barley beta-glucan
soluble fiber-enriched test foods were
formulated to provide either 3 or 5 g of
beta-glucan soluble fiber per day; a
placebo version of the test foods without
added barley beta-glucan extracts was
also used. Two concentrated barley
beta-glucan soluble fiber products were
used; one is the barley betafiber
produced from the manufacturing
process described in section II.B of this
preamble, and was described in the
study report as a low molecular weight
(LMW) extract; the other concentrated
barley beta-glucan soluble fiber product
of the study was described as a high
molecular weight (HMW) beta-glucan
extract. The HMW barley beta-glucan
extract was processed in a fashion
similar to that for barley betafiber but
omitted the cellulase enzymatic
PO 00000
Frm 00008
Fmt 4700
Sfmt 4700
hydrolysis step, thus producing a
concentrated source of barley betaglucan soluble fiber with a molecular
weight similar to that of the endogenous
beta-glucan soluble fiber in barley grain
from which it was derived.
Following a 4-week run-in period to
adjust to the low saturated/trans fat diet,
the subjects were randomly assigned to
one of five treatment groups: placebo
control, 3 g per day barley betafiber, 5
g per day barley betafiber, 3 g per day
HMW beta-glucan extract, and 5 g per
day HMW beta-glucan extract. Subjects
consumed the test foods daily for 6
weeks. Consumption of 3 or 5 g betaglucan per day from barley betafiber
significantly lowered serum total
cholesterol levels (6.0 percent and 9.9
percent, respectively) relative to the
placebo control group. Consumption of
3 or 5 g beta-glucan per day from the
HMW barley beta-glucan extract also
significantly lowered serum total
cholesterol (7.0 percent and 11.2
percent, respectively) relative to the
placebo control group. Serum LDL
cholesterol levels were significantly
decreased in all active treatment groups.
At the end of the 5-week intervention
period, the mean serum LDL cholesterol
level of the 3 g per day beta-glucan from
barley betafiber group was 10 mg/dL
lower than the mean serum LDL
cholesterol level of the placebo control
group, representing a 7.5 percent
reduction in LDL cholesterol relative to
the placebo control group. The
reduction in mean serum LDL
cholesterol for the 5 g per day betaglucan from barley betafiber group
relative to the placebo control group
was 16 mg/dL or 12 percent. The
reduction in mean serum LDL
cholesterol for the 3 g per day HMW
beta-glucan group was 12 mg/dL or 8
percent relative to the placebo control
group. For the 5 g per day HMW betaglucan group, the reduction in mean
LDL cholesterol was 19 mg/dL or 13
percent relative to the placebo control
group. There were no statistically
significant differences between barley
betafiber and the HMW barley betaglucan extract groups, or between 3 g
per day or 5 g per day beta-glucan
groups, in the magnitude of the
cholesterol lowering effects.
The magnitude of cholesterollowering reported by Keenan et al. (Ref.
4) for 3 and 5 g per day beta-glucan from
barley betafiber is consistent with the
magnitude of cholesterol-lowering
observed with similar barley beta-glucan
soluble fiber intake levels consumed as
dry milled barley foods (70 FR 76150 at
76153). The randomized controlled
trials with dry milled barley foods that
FDA considered when previously
E:\FR\FM\25FER1.SGM
25FER1
rfrederick on PROD1PC67 with RULES
Federal Register / Vol. 73, No. 37 / Monday, February 25, 2008 / Rules and Regulations
amending the health claim to add dry
milled barley had reported mean serum
LDL cholesterol reductions of between
10 and 19 mg/dL from barley betaglucan intake levels of 3 to 8 g per day.
Based on evidence from the randomized
controlled trials of dry milled barley
ingredients which FDA relied upon
when adding barley products to the
health claim, the data for barley
betafiber from Keenan et al. are
consistent with the expected magnitude
of cholesterol-lowering from
consumption of the barley products
listed in current § 101.81(c)(2)(ii)(A)(5).
Clinical trial evidence of oat/barley
beta-glucan extracts other than barley
betafiber indicate that not all oat/barley
beta-glucan extracts affect serum total
and LDL cholesterol levels as
consistently as does consumption of the
intact oat and barley grain from which
they have been extracted (Refs. 10
through 19). This indicates that some
extraction processes negatively affect
whatever characteristics of beta-glucan
soluble fiber in whole grain oats and
barley that are responsible for the
cholesterol-lowering effect.
Accordingly, data from trials of betaglucan extracts and concentrates other
than barley betafiber support FDA’s
previous position (62 FR 3584 at 3587)
that oat and barley products will be
added to the health claim as eligible
sources of beta-glucan soluble fiber only
on a case-by-case basis when FDA is
presented with adequate supporting
evidence.
Evidence from the randomized
controlled trial reported by Keenan et al.
(Ref. 4) indicates that beta-glucan
soluble fiber from barley betafiber,
prepared as described in section II of
this preamble, is comparable to betaglucan soluble fiber from the oat and
barley sources now included in current
§ 101.81 in regard to cholesterollowering properties. Evidence from
randomized controlled trials of other oat
or barley beta-glucan extracts indicate
that some forms of processing of oat and
barley grain to extract or concentrate
beta-glucan can negatively affect
whatever properties of oat and barley
beta-glucan are responsible for the
cholesterol-lowering effect. Therefore,
results from Keenan et al. can not be
extrapolated to beta-glucan extracts
other than the specific products tested
in the trial. Results from the Keenan et
al. trial also demonstrate that the serum
cholesterol-lowering effects were
comparable for beta-glucan soluble fiber
from barley betafiber (i.e., the LMW
product in the Keenan et al. trial) and
for the barley beta-glucan extract that
was not subjected to beta-glucan
hydrolysis (the HMW product in the
VerDate Aug<31>2005
14:21 Feb 22, 2008
Jkt 214001
Keenan et al. trial) (Ref. 4). This
evidence demonstrates that the
cholesterol-lowering ability of betaglucan soluble fiber in barley betafiber
is not affected by the process used in the
manufacture of barley betafiber to
reduce the molecular weight of the
barley betafiber product.
IV. Decision to Amend the Health Claim
Available evidence demonstrates that
foods enriched with beta-glucan soluble
fiber from barley betafiber at levels
sufficient to provide at least 3 g betaglucan soluble fiber per day are effective
in lowering serum LDL-cholesterol
levels, which may reduce the risk of
CHD. As noted previously, when issuing
the 1997 oat beta-glucan health claim
final rule the agency concluded that the
beta-glucan soluble fiber component of
oat products plays a significant role in
the relationship between whole grain
oats and the risk of CHD based, in part,
on evidence that there is a dose
response between the level of betaglucan soluble fiber from whole oats
and the level of reduction in serum LDL
cholesterol, and evidence that intakes at
or above 3 g per day were more effective
in lowering serum lipids than lower
intake levels (62 FR 3584 at 3585). The
clinical trial results reported by Keenan
et al. (Ref. 4) demonstrating the
cholesterol-lowering effect of
consuming beta-glucan soluble fiber
from barley betafiber are consistent in
magnitude with what would be
expected based on the oat beta-glucan
soluble fiber/cholesterol-lowering doseresponse evidence, which was cited in
the 1997 oat beta-glucan health claim
final rule, and cholesterol-lowering
effect of consuming beta-glucan soluble
fiber from dry milled barley grain
ingredients (70 FR 76150 at 76155).
Thus, FDA concludes that the
cholesterol-lowering effect of betaglucan soluble fiber from barley
betafiber is comparable to that of betaglucan soluble fiber from whole grain
oat and dry milled barley sources
currently listed in § 101.81(c)(2)(ii)(A).
FDA also concludes that the scientific
evidence supports a minimum daily
effective intake of beta-glucan soluble
fiber from barley betafiber the same as
that which was previously found for
whole oat and dry milled barley sources
of beta-glucan soluble fiber, i.e., 3 g per
day. Therefore, FDA is amending
§ 101.81, by adding
§ 101.81(c)(2)(ii)(A)(6) to list barley
betafiber as an eligible source of betaglucan soluble fiber. Consistent with
current § 101.81(c)(2)(i)(G)(1), the source
of the 3 g or more per day of beta-glucan
soluble fiber may be from whole oats or
barley, including the barley betafiber
PO 00000
Frm 00009
Fmt 4700
Sfmt 4700
9943
source, or a combination of oats and
barley eligible sources. In addition,
consistent with the description of other
oat and barley products listed in current
§ 101.81, amended § 101.81 will specify
barley betafiber by the method of
production as described in section II.B
of this preamble. The agency is satisfied
that the description of the method for
producing barley betafiber appropriately
characterizes the barley product being
added to the regulation. Further, barley
beta-glucan can be measured by the
same quantitative analytical method as
is currently specified in
§ 101.81(c)(2)(ii)(A) for the
determination of oat beta-glucan and
barley beta-glucan from whole grain
barley and dry milled barley products.
Based on the totality of the publicly
available scientific evidence, FDA
concludes there is significant scientific
agreement, among experts qualified by
scientific training and experience, for a
claim about the relationship between
certain beta-glucan soluble fiber sources
and reduced risk of CHD. Thus, FDA is
amending § 101.81(c)(2)(ii)(A) to
include barley betafiber derived from
whole barley flour, prepared as
described in section II.B of this
document, as an additional source of
beta-glucan soluble fiber.
The requirement in
§ 101.81(c)(2)(iii)(A) states that a food
bearing the claim on its label include
one of the ingredients listed within
§ 101.81(c)(2)(ii)(A) and that the
ingredient provide at least 0.75 gram of
beta-glucan soluble fiber per reference
amount customarily consumed (RACC)
of the food product. This level is based
on the minimum daily effective intake
of beta-glucan soluble fiber from barley
betafiber and is the same as that which
was previously found for whole oat and
dry milled barley sources of beta-glucan
soluble fiber, i.e., 3 g per day. FDA
arrived at a value of 0.75 gram betaglucan soluble fiber per RACC based on
a standard assumption that the daily
dietary intake is divided over four
eating occasions per day (three meals
and a snack) (62 FR 3584 at 3592). Thus,
adding barley betafiber as an additional
eligible source of beta-glucan soluble
fiber will further increase the type and
number of qualifying food products and
make it easier for consumers to select
barley and oat products at four eating
occasions per day. Thus, FDA is
retaining under the ‘‘Nature of the food
eligible to bear the claim’’ section of the
codified text of this interim final rule,
the criterion that foods eligible to bear
the claim contain at least 0.75 gram of
soluble fiber (§ 101.81(c)(2)(iii)(A)(2)).
There is strong consistent scientific
evidence that diets high in saturated fat
E:\FR\FM\25FER1.SGM
25FER1
rfrederick on PROD1PC67 with RULES
9944
Federal Register / Vol. 73, No. 37 / Monday, February 25, 2008 / Rules and Regulations
and cholesterol are associated with
elevated serum total and LDL
cholesterol, and that elevated serum
cholesterol levels are a major modifiable
risk factor for CHD. Expert groups
recommend lowering dietary saturated
fat and cholesterol as a primary lifestyle
change for reducing heart disease risk
(Ref. 8). Comments to the 1997 oat betaglucan health claim final rule expressed
concern that a CHD risk claim that does
not include a reference to a low
saturated fat, low cholesterol diet may
mislead consumers into thinking that
the single food, e.g., oat products, would
appear to be a ‘‘magic bullet’’ (62 FR
3584 at 3594). Further, based on the
scientific evidence, the role of soluble
fiber from whole oats in the diet is
generally recognized as being of smaller
magnitude in reducing CHD risk
compared to consumption of a low
saturated fat, low cholesterol diet. When
issuing the 1997 oat beta-glucan health
claim final rule, FDA concluded that
although selection of foods with soluble
fiber from whole oats is a useful adjunct
to selection of diets low in saturated fat
and cholesterol, in reducing CHD risk,
it would not be in the best interest of
public health nor consistent with the
scientific evidence to imply that
selecting diets with soluble fiber from
whole oats is a substitute for consuming
diets low in saturated fat and
cholesterol (id.). Therefore, FDA
required in the 1997 oat beta-glucan
health claim final rule that the health
claim statement include the phrase
‘‘diets that are low in saturated fat and
cholesterol and that include soluble
fiber from * * *’’ (§ 101.81(c)(2)(i)(A)).
FDA reiterated this position and
extended it to soluble fiber from listed
barley products when the agency
amended § 101.81 to add whole grain
barley and certain dry milled barley
products as eligible sources of betaglucan soluble fiber in 2005 (70 FR
76150 at 76156).
Beta-glucan soluble fiber from barley
betafiber functions comparably to betaglucan soluble fiber from the listed oat
and barley sources in current
§ 101.81(c)(2)(ii)(A) in its effect on
reducing LDL and total cholesterol.
Barley betafiber, as a source of betaglucan soluble fiber, is a useful adjunct
to selection of diets low in saturated fat
and cholesterol to reduce CHD risk.
Thus, the agency is requiring that the
beta-glucan soluble fiber from barley
betafiber health claim be subject to the
requirements in § 101.81(c)(2)(i)(A).
Including a reference to a low saturated
fat, low cholesterol diet in the health
claim will enable the public to
understand the relative significance of
VerDate Aug<31>2005

Jkt 214001
the information in the context of a total
daily diet (21 U.S.C. 343(r)(3)(A)(iii)).
V. Description of Amendments to the
Soluble Fiber from Certain Foods and
Risk of Coronary Heart Disease Health
Claim Regulation
A. Nature of the Substance; Eligible
Sources of Soluble Fiber
Section 101.81(c)(2)(ii) (nature of the
substance) lists the types and sources of
soluble fiber that have been
demonstrated to FDA’s satisfaction to
have a relationship to a reduced risk of
CHD. Section 101.81(c)(2)(ii)(A) lists
beta-glucan soluble fiber from whole oat
and barley sources, along with
specifying an AOAC INTERNATIONAL
method of analysis for beta-glucan
soluble fibe, which will be used by FDA
for verifying compliance. Section
101.81(c)(2)(ii)(A)(1) through
(c)(2)(ii)(A)(5) identifies the whole oat
and barley products that are eligible
sources of beta-glucan, i.e., oat bran,
rolled oats, whole oat flour, oatrim,
whole grain barley, and dry milled
barley.
FDA is amending § 101.81(c)(2)(ii)(A)
by adding § 101.81(c)(2)(ii)(A)(6), which
would specify barley betafiber as being
the ethanol isolated, soluble fraction of
cellulase and alpha-amylase hydrolyzed
whole grain barley flour, with a betaglucan content of at least 70 percent on
a dry weight basis (dwb). Thus,
§ 101.81(c)(2)(ii)(A)(6) will read as
follows ‘‘Barley betafiber. Barley
betafiber is the ethanol precipitated
soluble fraction of cellulase and alphaamylase hydrolyzed whole grain barley.
Barley betafiber is produced by
hydrolysis of whole grain barley flour,
as defined in paragraph (c)(2)(ii)(A)(5) of
this section, with a cellulase and alphaamylase enzyme preparation, to produce
a clear aqueous extract that contains
mainly partially hydrolyzed beta-glucan
and substantially hydrolyzed starch.
The soluble, partially hydrolyzed betaglucan is separated from the insoluble
material by centrifugation, and after
removal of the insoluble material, the
partially hydrolyzed beta-glucan soluble
fiber is separated from the other soluble
compounds by precipitation with
ethanol. The product is then dried,
milled and sifted. Barley betafiber shall
have a beta-glucan soluble fiber content
of at least 70 percent on a dry weight
basis.’’
B. Nature of the Food Eligible to Bear
the Claim
Section 101.81(c)(2)(iii)(A)(2) (nature
of the food) currently states ‘‘The food
containing the oatrim from paragraph
(c)(2)(ii)(A)(4) of this section shall
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
contain at least 0.75 g of beta-glucan
soluble fiber per reference amount
customarily consumed of the food
product;’’
Because FDA is amending § 101.81 to
add barley betafiber, FDA is amending
§ 101.81(c)(2)(iii)(A)(2) as follows ‘‘The
food containing the oatrim from
paragraph (c)(2)(ii)(A)(4) of this section
or the barley betafiber from paragraph
(c)(2)(ii)(A)(6) of this section shall
contain at least 0.75 g of beta-glucan
soluble fiber per reference amount
customarily consumed of the food
product;’’
C. Other Requirements
All other requirements in
§ 101.81(c)(1) through (c)(2)(i) and the
optional information in § 101.81(d) will
apply to the use of the health claim
authorized in § 101.81 for barley
betafiber-containing products.
D. Model Health Claims
This interim final rule to amend
existing § 101.81(c)(2) does not affect
the model health claims specified in
paragraph (e) of § 101.81. Thus, the
model health claims in § 101.81(e) apply
to a claim about beta-glucan soluble
fiber from barley betafiber and a
reduced risk of CHD.
VI. Analysis of Impacts
FDA has examined the impacts of this
interim final rule under Executive Order
12866 and the Regulatory Flexibility Act
(5 U.S.C. 601–612), and the Unfunded
Mandates Reform Act of 1995 (Public
Law 104–4). Executive Order 12866
directs agencies to assess all costs and
benefits of available regulatory
alternatives and, when regulation is
necessary, to select regulatory
approaches that maximize net benefits
(including potential economic,
environmental, public health and safety,
and other advantages; distributive
impacts; and equity). The agency
believes that this interim final rule is
not a significant regulatory action as
defined by the Executive order.
The Regulatory Flexibility Act
requires agencies to analyze regulatory
options that would minimize any
significant impact of a rule on small
entities. Because this interim final rule
concerns voluntary claims, the agency
certifies that the interim final rule will
not have a significant economic impact
on a substantial number of small
entities.
Section 202(a) of the Unfunded
Mandates Reform Act of 1995 requires
that agencies prepare a written
statement, which includes an
assessment of anticipated costs and
benefits, before proposing ‘‘any rule that
E:\FR\FM\25FER1.SGM
25FER1
rfrederick on PROD1PC67 with RULES
Federal Register / Vol. 73, No. 37 / Monday, February 25, 2008 / Rules and Regulations
includes any Federal mandate that may
result in the expenditure by State, local,
and tribal governments, in the aggregate,
or by the private sector, of $100,000,000
or more (adjusted annually for inflation)
in any one year.’’ The current threshold
after adjustment for inflation is $127
million, using the most current (2006)
Implicit Price Deflator for the Gross
Domestic Product. FDA does not expect
this interim final rule to result in any 1year expenditure that would meet or
exceed this amount.
FDA has identified the following
three options regarding this petition: (1)
Deny the petition; (2) authorize the
petition (add only barley betafiber to the
‘‘Soluble fiber from certain foods and
risk of coronary heart disease health
claim‘‘ in § 101.81 (the soluble fiber and
CHD health claim)); or (3) add barley
betafiber to the soluble fiber-CHD health
claim and also expand the scope of the
claim to include all sources of soluble
fiber. FDA concludes that authorizing
the petition by adding barley betafiber
to the soluble fiber and CHD health
claim is the best option of those
identified.
Option One: Deny the Petition
FDA can only define costs and
benefits relative to a baseline. FDA
usually selects the option of taking no
action as the baseline because it helps
readers identify the costs and benefits of
actions that change the status quo. In
this case, denying the petition would
correspond to taking no action because
it would imply no change in the soluble
fiber and CHD health claim and thus the
continuation of the status quo. By
definition, the baseline itself has no
costs or benefits. This does not mean
that we ignore the costs and benefits of
the baseline. Instead, it means that FDA
expresses the costs and benefits of the
baseline in how it calculates the costs
and benefits of the other regulatory
options.
Option Two: Authorize the Petition
(Add Only Barley Betafiber to the
Soluble Fiber and CHD Health Claim)
This option would allow producers
who use barley betafiber to use the
soluble fiber and CHD health claim on
their product labels under certain
conditions. Producers would only
choose to change product labels or
reformulate products if they believe that
the benefits that they will derive from
doing so are at least as great as the costs
of making those changes. FDA has
reviewed the data supplied in the
petition and concludes that the claim is
truthful and not misleading. If this
interim final rule is finalized without
change, FDA can be sure that to
whatever extent producers use the
claim, consumers will be in a better
VerDate Aug<31>2005
14:21 Feb 22, 2008
Jkt 214001
position, assuming that more
information that is truthful and not
misleading is always better for
consumers. Based on this, FDA can
conclude that adding barley betafiber to
the soluble fiber and CHD health claim
is better for social welfare than denying
the petition.
Option Three: Add Barley Betafiber to
the Soluble Fiber and CHD Health
Claim and Also Expand the Scope of the
Claim to Include All Sources of Soluble
Fiber
This option would allow producers
who use barley betafiber and all other
sources of soluble fiber to use the
soluble fiber and CHD health claim on
their product labels under certain
conditions rather than just listing
specific sources of soluble fiber. Similar
to option two, producers would only
choose to change product labels or
reformulate products if they believed
that the benefits that they will derive
from doing so are at least as great as the
costs of making those changes. In
addition, this option would reduce the
future burden on manufacturers of
petitioning FDA to use the soluble fiber
and CHD health claim for additional
sources of soluble fiber, and it would
also reduce the agency’s burden of
evaluating each petition for each
individual source of soluble fiber.
However, by expanding the use of the
claim to all sources of soluble fiber
without reviewing the scientific data on
each source, FDA would not be able to
verify that the claim was being used
under circumstances where it is truthful
and not misleading to consumers. If the
expanded claim was used on a product
that did not reduce the risk of CHD,
then the expanded claim could actually
result in an increase in CHD. This
would happen if consumers were
misled into thinking that they were
reducing their risk of CHD by
consuming a product that actually did
not reduce the risk of CHD. As a result,
they might not take other beneficial
steps that would decrease their risk of
CHD.
FDA cannot conclude that the cost
savings of option three outweigh the
increased risk of a false or misleading
claim being made under the expanded
claim. Therefore FDA cannot conclude
that option three is better for social
welfare than option two. Moreover, the
agency believes that expanding the
soluble fiber and CHD health claim to
all sources of soluble fiber without
reviewing the scientific data supporting
such a claim of CHD risk reduction for
each individual source of fiber would be
a failure to carry out our statutory
responsibility under section 403(r)(3)(B)
of the act to issue health claim

Frm 00011
Fmt 4700
Sfmt 4700
9945
regulations only when the agency
determines that there is significant
scientific agreement that the claim is
supported by the totality of publicly
available scientific evidence.
VII. Environmental Impact
The agency has determined under 21
CFR 25.32(p) that this action is of a type
that does not individually or
cumulatively have a significant effect on
the human environment. Therefore,
neither an environmental assessment
nor an environmental impact statement
is required.
VIII. Paperwork Reduction Act of 1995
FDA concludes that the labeling
provisions of this interim final rule are
not subject to review by the Office of
Management and Budget because they
do not constitute a ‘‘collection of
information’’ under the Paperwork
Reduction Act of 1995 (44 U.S.C. 3501–
3520). Rather, the food labeling health
claim on the association between
consumption of barley betafiber betaglucan soluble fiber and CHD risk is a
‘‘public disclosure of information
originally supplied by the Federal
Government to the recipient for the
purpose of disclosure to the public’’ (see
5 CFR 1320.3(c)(2)).
IX. Federalism
FDA has analyzed this interim final
rule in accordance with the principles
set forth in Executive Order 13132. FDA
has determined that the rule has a
preemptive effect on State law. Section
4(a) of the Executive order requires
agencies to ‘‘construe * * * a Federal
statute to preempt State law only where
the statute contains an express
preemption provision or there is some
other clear evidence that the Congress
intended preemption of State law, or
where the exercise of State authority
conflicts with the exercise of Federal
authority under the Federal statute.’’
Section 403A of the act (21 U.S.C. 343–
1) is an express preemption provision.
Section 403A(a)(5) of the act provides
that ‘‘* * * no State or political
subdivision of a State may directly or
indirectly establish under any authority
or continue in effect as to any food in
interstate commerce—* * * any
requirement respecting any claim of the
type described in section 403(r)(1) of the
act made in the label or labeling of food
that is not identical to the requirement
of section 403(r). * * *’’
Currently, this provision operates to
preempt States from imposing health
claim labeling requirements concerning
beta-glucan soluble fiber from barley
betafiber and reduced risk of CHD
because no such requirement had been

rfrederick on PROD1PC67 with RULES
9946
Federal Register / Vol. 73, No. 37 / Monday, February 25, 2008 / Rules and Regulations
imposed by FDA under section 403(r) of
the act. This interim final rule, if
finalized without change, would amend
existing food labeling regulations to add
barley betafiber as an eligible source of
beta-glucan soluble fiber to the
authorized health claim for soluble fiber
from certain foods and risk of CHD.
Although this rule would have a
preemptive effect in that it would
preclude States from issuing any health
claim labeling requirements for betaglucan soluble fiber from barley
betafiber and a reduced risk of CHD that
are not identical to those that would be
required by this interim final rule, this
preemptive effect is consistent with
what Congress set forth in section 403A
of the act. Section 403A(a)(5) of the act
displaces both State legislative
requirements and State common law
duties. (Medtronic v. Lohr, 518 U.S. 470,
503 (1996) (Breyer, J., concurring in part
and concurring in judgment); id. at 510
(O’Connor, J., joined by Rehnquist, C.J.,
Scalia, J., and Thomas, J., concurring in
part and dissenting in part); Cipollone v.
Liggett Group, Inc., 505 U.S. 504, 521
(1992) (plurality opinion); id. at 548–49
(Scalia, J., joined by Thomas, J.,
concurring in judgment in part and
dissenting in part).
FDA believes that the preemptive
effect of this interim final rule, if
finalized without change, is consistent
with Executive Order 13132. Section
4(e) of the Executive order provides that
‘‘when an agency proposes to act
through adjudication or rulemaking to
preempt State law, the agency shall
provide all affected State and local
officials notice and an opportunity for
appropriate participation in the
proceedings.’’ FDA provided the States
with an opportunity for appropriate
participation in this rulemaking on
December 12, 2007, when FDA’s
Division of Federal and State Relations
provided notice via fax and email
transmission to State health
commissioners, State agriculture
commissioners, food program directors,
and drug program directors as well as
FDA field personnel of FDA’s intent to
amend the health claim regulation
authorizing health claims for soluble
fiber from certain foods and risk of CHD
(§ 101.81). It advised the States of FDA’s
possible action and encouraged the
States and local governments to review
the petition and to provide any
comments to the docket (Docket No.
2006P–0393), until January 12, 2008.
FDA received no comments in response
to the notice. FDA is also providing an
opportunity for State and local officials
to comment on this interim final rule.
In conclusion, the agency has
determined that the preemptive effects
VerDate Aug<31>2005

Jkt 214001
of this interim final rule are consistent
with Executive Order 13132.
X. Issuance of an Interim Final Rule
and Immediate Effective Date
FDA is issuing this rule as an interim
final rule, effective immediately, with
an opportunity for public comment.
Section 403(r)(7) of the act authorizes us
to make proposed regulations issued
under section 403(r) of the act effective
upon publication pending consideration
of public comment and publication of a
final regulation, if the agency
determines that such action is necessary
for public health reasons. This authority
enables us to act promptly on petitions
that provide for information that is
necessary to: (1) Enable consumers to
develop and maintain healthy dietary
practices, (2) enable consumers to be
informed promptly and effectively of
important new knowledge regarding
nutritional and health benefits of food,
or (3) ensure that scientifically sound
nutritional and health information is
provided to consumers as soon as
possible. Proposed regulations made
effective upon publication under this
authority are deemed to be final agency
action for purposes of judicial review.
The legislative history indicates that
such regulations should be issued as
interim final rules (H. Conf. Rept. No.
105–399, at 98 (1997)).
We are satisfied that all three of the
criteria in section 403(r)(7)(A) of the act
have been met for the amendment to the
soluble fiber from certain foods and risk
of CHD health claim to list barley
betafiber as eligible source of betaglucan soluble fiber. This health claim
amendment will help enable consumers
to develop and maintain healthy dietary
practices. The health claim will also
provide consumers with important
knowledge regarding the effects of betaglucan soluble fiber in reducing the risk
of, and will provide consumers with
scientifically sound information on the
benefits of foods containing beta-glucan
soluble fiber from barley betafiber.
Therefore, we are using the authority
given to us in section 403(r)(7)(A) of the
act to issue an interim final rule
authorizing a health claim for soluble
fiber from barley betafiber and CHD,
effective immediately.
FDA invites public comment on this
interim final rule. The agency will
consider modifications to this interim
final rule based on comments made
during the comment period. Interested
persons may submit to the Division of
Dockets Management, in any of the

Food Labeling: Health Claims; Soluble Fiber From Certain Foods
and Risk of Coronary Heart Disease
AGENCY: Food and Drug Administration, HHS.
ACTION: Interim final rule.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) is amending the health
claim regulation entitled ``Soluble fiber from certain foods and risk
of coronary heart disease (CHD)'' to add barley betafiber as an
additional eligible source of beta-glucan soluble fiber. Barley
betafiber is the ethanol precipitated soluble fraction of cellulase and
alpha-amylase hydrolyzed whole grain barley flour. FDA is taking this
action in response to a health claim petition submitted by Cargill,
Inc. FDA previously concluded that there was significant scientific
agreement that a claim characterizing the relationship between beta-
glucan soluble fiber of certain whole oat and whole grain barley
products and CHD risk is supported by the totality of publicly
available scientific evidence. Based on the totality of publicly
available scientific evidence, FDA now has concluded that in addition
to certain whole oat and whole grain barley products, barley betafiber
is also an appropriate source of beta-glucan soluble fiber. Therefore,
FDA is amending the health claim regulation entitled ``Soluble fiber
from certain foods and risk of CHD'' to include barley betafiber as
another eligible source of beta-glucan soluble fiber.

SUPPLEMENTARY INFORMATION:
I. Background
A. The Nutrition Labeling and Education Act of 1990
The Nutrition Labeling and Education Act of 1990 (the 1990
amendments) (Public Law 101-535) amended the Federal Food, Drug, and
Cosmetic Act (the act) in a number of important ways. One aspect of the
1990 amendments was that they clarified FDA's authority to regulate
health claims on food labels and in food labeling.
FDA (we) issued several new regulations in 1993 that implemented
the health claim provisions of the 1990 amendments. Among these were 21
CFR 101.14, Health claims: general requirements (58 FR 2478, January 6,
1993) and Sec. 101.70 (21 CFR 101.70), Petitions for health claims (58
FR 2478), which set out the general requirements for the authorization
and use of health claims and established a process for petitioning the
agency to authorize health claims about substance-disease relationships
and set out the types of information that any such petition must
include. These regulations became effective on May 8, 1993.
When implementing the 1990 amendments, FDA also conducted a review
of evidence for a relationship between dietary fiber and cardiovascular
disease (CVD). Based on this review, the agency concluded that the
available scientific evidence did not justify authorization of a health
claim relating dietary fiber to reduced risk of CVD (58 FR 2552,
January 6, 1993) (1993 dietary fiber and CVD health claim final rule).
However, FDA did conclude there was significant scientific agreement
that the totality of publicly available scientific evidence supported
an association between types of foods that are low in saturated fat and
cholesterol and that naturally are good sources of soluble dietary
fiber (i.e., fruits, vegetables, and grain products) and reduced risk
of CHD\1\. Therefore, FDA authorized a health claim about the
relationship between diets low in saturated fat and cholesterol and
high in vegetables, fruit, and grain products that contain soluble
fiber and a reduced risk of CHD (21 CFR 101.77; 58 FR 2552 at 2572). In
the 1993 dietary fiber and CVD health claim final rule, FDA commented
that if a manufacturer could document with appropriate evidence that
consumption of the type of soluble fiber in a particular food has the
effect of lowering blood low density lipoprotein (LDL) cholesterol, and
has no adverse effects on other heart disease risk factors (e.g., high
density lipoprotein cholesterol), it should petition for authorization
of a health claim specific for that particular dietary fiber-containing
food (58 FR 2552 at 2567).

B. Soluble Fiber from Certain Foods and Risk of CHD Health Claim (21
CFR 101.81)
In 1995, FDA received a petition for a health claim on the
relationship between oat bran and rolled oats and reduced risk of CHD.
FDA concluded there was significant scientific agreement that the
totality of publicly available scientific evidence supported the
relationship between consumption of whole oat products and reduced risk
of CHD. FDA further concluded that the type of soluble fiber found in
whole oats, i.e., beta-glucan soluble fiber, is the component primarily
responsible for the hypocholesterolemic effects associated with
consumption of whole oat foods as part of a diet that is low in
saturated fat and cholesterol (62 FR 3584 at 3597 and 3598, January 23,
1997). As such, the final rule authorized a health claim relating the
consumption of beta-glucan soluble fiber in whole oat foods, as part of
a diet low in saturated fat and cholesterol, and reduced risk of CHD
(the 1997 oat beta-glucan health claim final rule). The source of beta-
glucan soluble fiber in foods bearing this health claim had to be one
of three eligible whole oat products; i.e., oat bran, rolled oats, or
whole oat flour (see Sec. 101.81(c)(2)(ii)(A)). In the 1997 oat beta-
glucan health claim final rule, FDA anticipated the likelihood that
other sources and types of soluble fibers could also affect blood lipid
levels, and thus, may reduce heart disease risk (62 FR 3584 at 3587).
At that time, FDA considered structuring the final rule as an umbrella
regulation authorizing the use of a claim for ``soluble fiber from
certain foods`` and risk of CHD. Such action would have allowed
flexibility in expanding the claim to other specific food sources of
soluble fiber when consumption of those foods has been demonstrated to
help reduce the risk of heart disease. However, the agency concluded
that it was premature to do so because FDA had not reviewed the
totality of evidence on other, non-whole oat sources of soluble fiber
(62 FR 3584 at 3588).
The agency amended Sec. 101.81 (21 CFR 101.81), in response to a
health claim petition to add a health claim relating soluble fiber from
psyllium seed husk and CHD risk (63 FR 8103, February 18, 1998). At
this time, FDA also modified the heading in Sec. 101.81 from ``* * *
Soluble fiber from whole oats and risk of coronary heart disease'' to
``* * * Soluble fiber from certain foods and risk of coronary heart
disease (CHD)'' (63 FR 8103). FDA has also amended Sec. 101.81, in
response to health claim petitions, to include oatrim, whole grain
barley, and certain dry milled barley grain products as eligible
sources of beta-glucan soluble fiber. In 2002, FDA amended Sec. 101.81
to add oatrim, which is the soluble fraction of alpha-amylase
hydrolyzed oat bran or whole oat flour, as an eligible source of beta-
glucan soluble fiber (67 FR 61733, October 2, 2002), and finally, FDA
amended Sec. 101.81 to add whole grain barley and certain dry milled
barley grain products as eligible sources of beta-glucan soluble fiber
in 2005 (70 FR 76150, December 23, 2005).
II. Petition and Grounds
A. The Petition
Cargill, Inc. (petitioner), submitted a health claim petition to
FDA on June 20, 2006, under section 403(r)(4) of the act (21 U.S.C.
343(r)(4)). The petition requested that the agency expand the ``Soluble
fiber from certain foods and risk of coronary heart disease health
claim'' (Sec. 101.81) to include ``barley betafiber'' (described in
section II.B of this document) as an eligible food ingredient source of
beta-glucan soluble fiber in addition to the oat and whole grain and
dry milled barley ingredients now listed (Ref. 1). On September 28,
2006, the agency notified the petitioner that it had completed its
initial review of the petition and that the petition was
[[Page 9940]]
being filed for further action in accordance with section 403(r)(4) of
the act. If the agency does not act, by either denying the petition or
issuing a proposed regulation to authorize the health claim, within 90
days of the date of filing for further action, the petition is deemed
to be denied unless an extension is mutually agreed upon by the agency
and the petitioner (section 403(r)(4)(A)(i) of the act and Sec.
101.70(j)(3)(iii)). The petitioner and FDA subsequently mutually agreed
to extend the deadline for the agency's decision on the petition to
March 6, 2008. The petitioner also requested that FDA issue an interim
final rule by which labeling of foods that contain ``barley betafiber''
in appropriate amounts could bear the health claim prior to publication
of a final rule.
B. Nature of the Substance
The substance that is the subject of the oat/barley portion of
current Sec. 101.81 is beta-glucan soluble fiber from the specific oat
and barley food products listed in Sec. 101.81(c)(2)(ii)(A). Current
Sec. 101.81(c)(2)(ii)(A) has been amended twice previously to list
additional oat or barley food products as eligible sources (67 FR 61773
and 70 FR 76150). Similar to these previous actions, FDA is now, in
response to Cargill's health claim petition, amending Sec.
101.81(c)(2)(ii)(A) to list barley betafiber as an eligible source of
barley beta-glucan soluble fiber.
The petition states that barley betafiber is a concentrated barley
beta-glucan soluble fiber product derived from whole barley flour. The
petitioner's description of the barley betafiber manufacturing process
reflects information contained in the petitioner's patent entitled
``Improved Dietary Fiber Containing Materials Comprising Low Molecular
Weight Glucan'' (World Intellectual Property Organization,
International Publication Number WO 2004/086878 A2) (Ref. 2) and a
report of an expert panel on the generally recognized as safe (GRAS)
status of barley betafiber commissioned by the petitioner (Ref. 3). The
patent and the GRAS status report provide information on multiple
variations of procedures for manufacturing concentrated barley beta-
glucan soluble fiber products; these procedures differ from the
manufacturing procedures for producing the unique barley betafiber
substance that is the subject of the petition. Further, the clinical
trial reported in the petition tested two different barley beta-glucan
soluble fiber concentrates--a high molecular weight concentrate and a
low molecular weight concentrate. The petitioner specified that the
barley betafiber product, which is the subject of the petition, is only
the low molecular weight concentrate studied in the clinical trial
(Ref. 4). FDA was not satisfied that the information in the petition
was sufficiently specific in describing the manufacturing process for
the unique barley betafiber product for which there is scientific
evidence to permit a showing that the product is comparable in
cholesterol-lowering ability to the other oat and barley food products
listed in current Sec. 101.81(c)(2)(ii)(A). Discussion between the
agency and the petitioner resulted in the description of the barley
betafiber manufacturing process presented in the following paragraph
and in final Sec. 101.81(c)(2)(ii)(A)(6) (Refs. 2 through 5).
Barley betafiber is produced from an aqueous slurry of whole grain
barley flour, starting with addition of an exogenous grain liquefying
enzyme preparation with cellulase and alpha-amylase activity, derived
from Bacillus amyloliquefaciens. The cellulase activity of the enzyme
preparation acts on the beta-glucan soluble fiber in barley flour,
since beta-glucan is a type of cellulose, and the alpha-amylase
activity of the enzyme preparation acts on the starch in the barley
flour. The temperature of the slurry is kept at or above the
gelatinization temperature of the barley starch but below cellulase
enzyme inactivation temperature; i.e., about 65[deg] C, for about 30 to
60 minutes, to facilitate a partial hydrolysis of both the beta-glucan
soluble fiber and starch. The pH of the slurry is kept in the range of
about 5 to 7. When the cellulase enzymatic hydrolysis of barley flour
has modified the beta-glucan soluble fiber to the desired extent, the
cellulase activity of the enzyme preparation is heat inactivated. After
the cellulase activity of the enzyme preparation has been deactivated,
an exogenous thermo-stable amylolytic enzyme is added to the barley
flour slurry for continued hydrolysis of starch molecules at the higher
temperature. The slurry is held at the higher temperature until
substantially all the starch has been hydrolyzed. A clear aqueous
extract, which contains barley betafiber and the sugars and dextrins
resulting from substantial hydrolysis of starch is then separated from
insoluble material by centrifugation. Barley betafiber is precipitated
from the aqueous extract supernatant with ethanol to separate it from
other soluble components (i.e., substantially hydrolyzed starch,
protein, lipids and other minor components) that remain suspended in
the aqueous extract supernatant. The resultant barley betafiber
precipitate is then dried and milled. The molecular weight range of
barley betafiber produced by this procedure is 120 to 400 kilodaltons
(Refs. 2, 3, and 5). The molecular weight range of barley betafiber is
substantially reduced from that of native barley beta-glucan soluble
fiber. The molecular weight range of native barley beta-glucan soluble
fiber has been reported to range from about 500 to 3,330 kilodaltons
depending upon the cultivars and applied extraction procedures,
although lower molecular weight values of 80 to 300 kilodaltons have
also been reported (Ref. 1). In final Sec. 101.81(c)(2)(ii)(A)(6), FDA
defines barley betafiber by its manufacturing process, as follows
``Barley betafiber. Barley betafiber is the ethanol precipitated
soluble fraction of cellulase and alpha-amylase hydrolyzed whole grain
barley. Barley betafiber is produced by hydrolysis of whole grain
barley flour, as defined in paragraph (c)(2)(ii)(A)(5) of this section,
with a cellulase and alpha-amylase enzyme preparation, to produce a
clear aqueous extract that contains mainly partially hydrolyzed beta-
glucan and substantially hydrolyzed starch. The soluble, partially
hydrolyzed beta-glucan is separated from the insoluble material by
centrifugation, and after removal of the insoluble material, the
partially hydrolyzed beta-glucan soluble fiber is separated from the
other soluble compounds by precipitation with ethanol. The product is
then dried, milled and sifted. Barley betafiber shall have a beta-
glucan soluble fiber content of at least 70 percent on a dry weight
basis.''
C. Review of Preliminary Requirements for a Health Claim
1. The Substance Is Associated With a Disease for Which the U.S.
Population Is at Risk
CHD continues to be a disease that has a large impact on mortality
and morbidity in the general adult U.S. population. As explained in the
existing beta-glucan soluble fiber health claim (Sec. 101.81(b)), FDA
recognizes the CHD risk reduction benefit of certain foods that are
sources of soluble dietary fiber resulting from effects on lowering
blood total and LDL cholesterol. Although age-adjusted CHD mortality
rates in the United States had been steadily decreasing since
approximately 1960, recent evidence has suggested that the decline in
CHD mortality has slowed (Ref. 6). Heart disease has been recognized as
the leading cause of death in the United States for at least the last
50 years (Ref. 6). Based on these facts,
[[Page 9941]]
FDA concludes that, as required in Sec. 101.14(b)(1), CHD is a disease
for which the U.S. population is at risk.
2. The Substance Is a Food
The substance of the health claim is beta-glucan soluble fiber from
listed oat and barley sources. The petitioner requests an amendment to
add barley betafiber to the list of eligible sources of beta-glucan
soluble fiber. Barley betafiber is derived from whole barley flour.
Barley flour is a commonly consumed human food and beta-glucan soluble
fiber is a nutrient component of this food. Thus, the beta-glucan
soluble fiber from barley betafiber, a processed whole barley flour
product, is a ``substance'' as defined in Sec. 101.14(a)(2). Health
claim general requirements provide that where a substance is to be
consumed at ``other than decreased dietary levels,'' the substance must
contribute taste, aroma, nutritive value, or any other technical effect
as listed in 21 CFR 170.3(o), and must retain that attribute when
consumed at levels necessary to justify the claim (Sec.
101.14(b)(3)(i)). The level necessary to justify the claim is 0.75 g
beta-glucan soluble fiber per serving. The term ``nutritive value'' is
defined in Sec. 101.14(a)(3) as ``a value in sustaining human
existence by such processes as promoting growth, replacing lost
essential nutrients, or providing energy.'' The petitioner provided
several examples of food categories (bars, beverages, bread, breakfast
cereals, cookies, crackers, instant rice, pasta, muffins, salad
dressings, snack chips, soups, tortillas and taco shells, vegetarian
patties/crumbles, and reduced fat yogurt) in which barley betafiber
could be used as an ingredient at a maximum level of 3 grams (g) beta-
glucan soluble fiber per serving. Beta-glucan soluble fiber at 0.75 to
3 g per serving contributes nutritive value because it provides a
source of calories and soluble fiber. In addition to its role as a
source of beta-glucan soluble fiber, barley betafiber also has
technical effects, including food applications as a thickener (e.g.,
soups), texturizer (e.g., snack foods), humectant (e.g., retain
moisture of tortillas), or fat replacer (e.g., dressings for salads).
Therefore, FDA concludes that the preliminary requirement of Sec.
101.14(b)(3)(i) is satisfied.
3. The Substance Is Safe and Lawful
Section 101.14(b)(3)(ii) requires that the substance be a food or a
food ingredient or a component of a food ingredient whose use at the
levels necessary to justify a claim has been demonstrated by the
proponent of the claim, to FDA's satisfaction, to be safe and lawful
under the applicable food safety provisions of the act. The petitioner
asserts that the use of barley betafiber as a food ingredient is GRAS.
The petitioner included in its health claim petition documentation of
its 2003 GRAS self-determination for barley betafiber, which contains
70 percent or more pure barley beta-glucan soluble fiber as evidence
that barley betafiber meets the safe and lawful requirement (Ref. 3).
FDA also received a notice informing FDA that the petitioner
determined, through scientific procedures, that the use of barley
betafiber is GRAS. FDA issued a letter (Ref. 7) in response to this
notice stating that the agency had no questions at the time regarding
petitioner's conclusions that barley betafiber is GRAS under the
intended conditions of use.
The 2003 Cargill GRAS self-determination stipulates that barley
betafiber is obtained from food-grade whole grain barley flour by water
extraction at elevated temperature, while starch is removed during the
extraction process by treatment with enzymes that are GRAS for use in
food manufacturing processes, specifically alpha-amylases from Bacillus
licheniformis and B. amyloliquefaciens. The extracted barley betafiber
is recovered by precipitation with denatured ethanol suitable for food
production, and contains 70 percent or more beta-glucan, 2 to 12
percent protein, and less than 3 percent of each sugars, lipids, and
inorganic salts. The basis of the safety determination relies on the
fact that barley betafiber contains only native components of barley
and is formed by the action of applied food-grade enzymes, residues, or
processing aids.
In addition, barley is a traditional food with a long history of
safe use, since at least 8,000 B.C. based on archeological discoveries
(Ref. 3). In the Maghreb countries of Morocco, Algeria, Libya, and
Tunisia, barley is used in a variety of traditional foods (bread, soup,
porridge), resulting in an average intake of up to 172 g per person per
day (Morocco). With this intake of barley, about 6 g per person per day
of pure beta-glucan soluble fiber is consumed. The preparation of these
traditional foods involves baking or boiling for longer periods of
time, which ensures extraction of beta-glucan from its natural context
(cell walls, complexes with proteoglycans). The physiological
properties of beta-glucan as a dietary fiber may, therefore, be found
in these traditional foods as is intended to be achieved with the
addition to processed foods of barley beta-glucan concentrate.
The intended uses of barley betafiber listed as a food ingredient
stated in the 2003 Cargill GRAS self-determination include the
following food categories: Bars, beverages, bread (whole grain and
specialty), breakfast cereals (ready to eat and cooked), cookies
(lite), crackers (reduced fat), instant rice, macaroni products,
muffins (reduced fat), salad dressings (lite), snack chips (reduced
fat), soups, tortillas and taco shells, vegetarian patties/crumbles,
and reduced fat yogurt. The maximum incorporation rate for each of
these food applications is 3 g beta-glucan soluble fiber from barley
betafiber per serving.
FDA concludes that the petitioners have satisfied the preliminary
requirement of Sec. 101.14(b)(3)(ii) to demonstrate, to FDA's
satisfaction, that the use of beta-glucan soluble fiber from barley
betafiber at levels necessary to justify the health claim is safe and
lawful under the applicable food safety provisions of the act. The
agency has not made its own determination regarding the GRAS status of
barley betafiber or beta-glucan soluble fiber from barley betafiber.
Furthermore, the agency notes that a regulation to authorize a health
claim for a substance should not be interpreted as affirmation that the
substance is GRAS.
III. Review of Scientific Evidence of the Substance-Disease
Relationship
A. Basis for Evaluating the Relationship Between Beta-Glucan Soluble
Fiber from Barley Betafiber and CHD
The types of data that FDA has recognized in previous CHD health
claim evaluations as useful for assessing CHD risk reduction are:
Coronary events (myocardial infarction, ischemia), cardiovascular
death, atherosclerosis, high blood pressure, serum total cholesterol,
and serum LDL cholesterol. FDA considers high blood pressure, serum
total cholesterol, and serum LDL cholesterol levels to be the only
currently validated surrogate measures for CHD risk (Ref. 8). Elevated
levels of serum total and LDL cholesterol, a prerequisite for
atherosclerotic disease, is a major modifiable risk factor in the
development of CHD (Ref. 8). For these reasons, the agency based its
original evaluation of the relationship between oat beta-glucan soluble
fiber and CHD risk (62 FR 3584) and subsequent evaluations to add
oatrim (67 FR 61773) and barley as eligible sources of beta-glucan
soluble fiber (70 FR 76150) in the health claim, primarily on evidence
for serum total and LDL cholesterol-lowering effects of beta-glucan
soluble fiber containing food ingredients. As such, our evaluation of
the evidence
[[Page 9942]]
supporting the petitioned request to extend the eligible barley sources
to include barley betafiber (as described in section II.B of this
preamble), focused on evidence from human randomized controlled trials
of the effects of consuming beta-glucan soluble fiber from barley
betafiber on blood lipids. This focus is consistent with existing Sec.
101.81 in which FDA concluded that there is significant scientific
agreement that the relationship between CHD risk and consumption of
beta-glucan soluble fiber from certain oat and barley food ingredients
is mediated primarily by the effect of the beta-glucan soluble fiber on
serum lipids.
FDA's determination of significant scientific agreement that the
totality of publicly available scientific evidence supports the
relationship between beta-glucan soluble fiber from certain oat and
barley foods and CHD risk is documented in rulemaking for Sec. 101.81.
When issuing the 1997 oat beta-glucan health claim final rule, the
agency concluded that the beta-glucan soluble fiber component of oat
products plays a significant role in the relationship between whole
grain oats and the risk of CHD based, in part, on evidence that there
is a dose response between the level of beta-glucan soluble fiber from
whole oats and the level of reduction in serum LDL cholesterol, and
evidence that intakes at or above 3 g per day were more effective in
lowering serum lipids than lower intake levels (62 FR 3584 at 3585). In
the 2002 and 2005 amendments to the health claim to add oatrim and
whole grain and dry milled barley products, respectively, as eligible
sources of beta-glucan soluble fiber, the agency considered evidence
that beta-glucan soluble fiber from those sources had comparable
cholesterol-lowering effects to that from the sources previously listed
in Sec. 101.81(c)(2)(ii)(A) as further support for FDA's previous
determination that there is significant scientific agreement that a
relationship exists between consumption of certain beta-glucan soluble
fiber sources and reduced risk of CHD (67 FR 61773 at 61779 and 70 FR
76150 at 76155). Similarly, FDA considers that scientific evidence to
establish that the cholesterol-lowering effects of beta-glucan soluble
fiber from barley betafiber are comparable to the effects of beta-
glucan soluble fiber from the oat/barley products in current Sec.
101.81(c)(2)(ii)(A) builds on the substantial base of scientific
evidence that already establishes significant scientific agreement for
the association between consumption of the oat/barley products now
listed and reduced risk of CHD. FDA's review of the evidence to support
the petitioned amendment of the health claim regulation entitled
``Soluble fiber from certain foods and risk of CHD'' was conducted
consistent with FDA published guidance on significant scientific
agreement in the review of health claims (Ref. 9) and focused on
evidence from intervention studies.
B. Assessment of Intervention Studies
This petition identified one relevant human randomized controlled
trial of how consumption of beta-glucan soluble fiber from barley
betafiber affects heart disease risk and serum lipid levels. A summary
of this trial was included in the petition and subsequently published
in a peer reviewed scientific journal (Ref. 4). FDA also evaluated
reported results from randomized controlled trials of other types of
beta-glucan concentrates, extracts, and gums (Refs. 10 through 19).
The study reported in Keenan et al. 2007 (Ref. 4) investigated the
effects of consuming concentrated barley beta-glucan soluble fiber-
enriched foods (fruit drink and corn flakes) on blood lipids in
hypercholesterolemic men and women. The study was conducted as a
randomized, double-blind, placebo-controlled, parallel arm study of
five groups with 30 to 32 subjects per group. The study included a
total of 155 hypercholesterolemic adult subjects, between 25 and 73
years of age, with baseline serum LDL cholesterol levels between 140
and 190 milligrams per deciliter (mg/dL). The subjects were instructed
to follow a diet low in saturated and trans fatty acids (less than 10
percent kilocalories (kcals) per day) and to consume three servings of
the concentrated barley beta-glucan soluble fiber-enriched test foods
per day, one serving with each of three major meals. The concentrated
barley beta-glucan soluble fiber-enriched test foods were formulated to
provide either 3 or 5 g of beta-glucan soluble fiber per day; a placebo
version of the test foods without added barley beta-glucan extracts was
also used. Two concentrated barley beta-glucan soluble fiber products
were used; one is the barley betafiber produced from the manufacturing
process described in section II.B of this preamble, and was described
in the study report as a low molecular weight (LMW) extract; the other
concentrated barley beta-glucan soluble fiber product of the study was
described as a high molecular weight (HMW) beta-glucan extract. The HMW
barley beta-glucan extract was processed in a fashion similar to that
for barley betafiber but omitted the cellulase enzymatic hydrolysis
step, thus producing a concentrated source of barley beta-glucan
soluble fiber with a molecular weight similar to that of the endogenous
beta-glucan soluble fiber in barley grain from which it was derived.
Following a 4-week run-in period to adjust to the low saturated/
trans fat diet, the subjects were randomly assigned to one of five
treatment groups: placebo control, 3 g per day barley betafiber, 5 g
per day barley betafiber, 3 g per day HMW beta-glucan extract, and 5 g
per day HMW beta-glucan extract. Subjects consumed the test foods daily
for 6 weeks. Consumption of 3 or 5 g beta-glucan per day from barley
betafiber significantly lowered serum total cholesterol levels (6.0
percent and 9.9 percent, respectively) relative to the placebo control
group. Consumption of 3 or 5 g beta-glucan per day from the HMW barley
beta-glucan extract also significantly lowered serum total cholesterol
(7.0 percent and 11.2 percent, respectively) relative to the placebo
control group. Serum LDL cholesterol levels were significantly
decreased in all active treatment groups. At the end of the 5-week
intervention period, the mean serum LDL cholesterol level of the 3 g
per day beta-glucan from barley betafiber group was 10 mg/dL lower than
the mean serum LDL cholesterol level of the placebo control group,
representing a 7.5 percent reduction in LDL cholesterol relative to the
placebo control group. The reduction in mean serum LDL cholesterol for
the 5 g per day beta-glucan from barley betafiber group relative to the
placebo control group was 16 mg/dL or 12 percent. The reduction in mean
serum LDL cholesterol for the 3 g per day HMW beta-glucan group was 12
mg/dL or 8 percent relative to the placebo control group. For the 5 g
per day HMW beta-glucan group, the reduction in mean LDL cholesterol
was 19 mg/dL or 13 percent relative to the placebo control group. There
were no statistically significant differences between barley betafiber
and the HMW barley beta-glucan extract groups, or between 3 g per day
or 5 g per day beta-glucan groups, in the magnitude of the cholesterol
lowering effects.
The magnitude of cholesterol-lowering reported by Keenan et al.
(Ref. 4) for 3 and 5 g per day beta-glucan from barley betafiber is
consistent with the magnitude of cholesterol-lowering observed with
similar barley beta-glucan soluble fiber intake levels consumed as dry
milled barley foods (70 FR 76150 at 76153). The randomized controlled
trials with dry milled barley foods that FDA considered when previously
[[Page 9943]]
amending the health claim to add dry milled barley had reported mean
serum LDL cholesterol reductions of between 10 and 19 mg/dL from barley
beta-glucan intake levels of 3 to 8 g per day. Based on evidence from
the randomized controlled trials of dry milled barley ingredients which
FDA relied upon when adding barley products to the health claim, the
data for barley betafiber from Keenan et al. are consistent with the
expected magnitude of cholesterol-lowering from consumption of the
barley products listed in current Sec. 101.81(c)(2)(ii)(A)(5).
Clinical trial evidence of oat/barley beta-glucan extracts other
than barley betafiber indicate that not all oat/barley beta-glucan
extracts affect serum total and LDL cholesterol levels as consistently
as does consumption of the intact oat and barley grain from which they
have been extracted (Refs. 10 through 19). This indicates that some
extraction processes negatively affect whatever characteristics of
beta-glucan soluble fiber in whole grain oats and barley that are
responsible for the cholesterol-lowering effect. Accordingly, data from
trials of beta-glucan extracts and concentrates other than barley
betafiber support FDA's previous position (62 FR 3584 at 3587) that oat
and barley products will be added to the health claim as eligible
sources of beta-glucan soluble fiber only on a case-by-case basis when
FDA is presented with adequate supporting evidence.
Evidence from the randomized controlled trial reported by Keenan et
al. (Ref. 4) indicates that beta-glucan soluble fiber from barley
betafiber, prepared as described in section II of this preamble, is
comparable to beta-glucan soluble fiber from the oat and barley sources
now included in current Sec. 101.81 in regard to cholesterol-lowering
properties. Evidence from randomized controlled trials of other oat or
barley beta-glucan extracts indicate that some forms of processing of
oat and barley grain to extract or concentrate beta-glucan can
negatively affect whatever properties of oat and barley beta-glucan are
responsible for the cholesterol-lowering effect. Therefore, results
from Keenan et al. can not be extrapolated to beta-glucan extracts
other than the specific products tested in the trial. Results from the
Keenan et al. trial also demonstrate that the serum cholesterol-
lowering effects were comparable for beta-glucan soluble fiber from
barley betafiber (i.e., the LMW product in the Keenan et al. trial) and
for the barley beta-glucan extract that was not subjected to beta-
glucan hydrolysis (the HMW product in the Keenan et al. trial) (Ref.
4). This evidence demonstrates that the cholesterol-lowering ability of
beta-glucan soluble fiber in barley betafiber is not affected by the
process used in the manufacture of barley betafiber to reduce the
molecular weight of the barley betafiber product.
IV. Decision to Amend the Health Claim
Available evidence demonstrates that foods enriched with beta-
glucan soluble fiber from barley betafiber at levels sufficient to
provide at least 3 g beta-glucan soluble fiber per day are effective in
lowering serum LDL-cholesterol levels, which may reduce the risk of
CHD. As noted previously, when issuing the 1997 oat beta-glucan health
claim final rule the agency concluded that the beta-glucan soluble
fiber component of oat products plays a significant role in the
relationship between whole grain oats and the risk of CHD based, in
part, on evidence that there is a dose response between the level of
beta-glucan soluble fiber from whole oats and the level of reduction in
serum LDL cholesterol, and evidence that intakes at or above 3 g per
day were more effective in lowering serum lipids than lower intake
levels (62 FR 3584 at 3585). The clinical trial results reported by
Keenan et al. (Ref. 4) demonstrating the cholesterol-lowering effect of
consuming beta-glucan soluble fiber from barley betafiber are
consistent in magnitude with what would be expected based on the oat
beta-glucan soluble fiber/cholesterol-lowering dose-response evidence,
which was cited in the 1997 oat beta-glucan health claim final rule,
and cholesterol-lowering effect of consuming beta-glucan soluble fiber
from dry milled barley grain ingredients (70 FR 76150 at 76155). Thus,
FDA concludes that the cholesterol-lowering effect of beta-glucan
soluble fiber from barley betafiber is comparable to that of beta-
glucan soluble fiber from whole grain oat and dry milled barley sources
currently listed in Sec. 101.81(c)(2)(ii)(A). FDA also concludes that
the scientific evidence supports a minimum daily effective intake of
beta-glucan soluble fiber from barley betafiber the same as that which
was previously found for whole oat and dry milled barley sources of
beta-glucan soluble fiber, i.e., 3 g per day. Therefore, FDA is
amending Sec. 101.81, by adding Sec. 101.81(c)(2)(ii)(A)(6) to list
barley betafiber as an eligible source of beta-glucan soluble fiber.
Consistent with current Sec. 101.81(c)(2)(i)(G)(1), the source of the
3 g or more per day of beta-glucan soluble fiber may be from whole oats
or barley, including the barley betafiber source, or a combination of
oats and barley eligible sources. In addition, consistent with the
description of other oat and barley products listed in current Sec.
101.81, amended Sec. 101.81 will specify barley betafiber by the
method of production as described in section II.B of this preamble. The
agency is satisfied that the description of the method for producing
barley betafiber appropriately characterizes the barley product being
added to the regulation. Further, barley beta-glucan can be measured by
the same quantitative analytical method as is currently specified in
Sec. 101.81(c)(2)(ii)(A) for the determination of oat beta-glucan and
barley beta-glucan from whole grain barley and dry milled barley
products. Based on the totality of the publicly available scientific
evidence, FDA concludes there is significant scientific agreement,
among experts qualified by scientific training and experience, for a
claim about the relationship between certain beta-glucan soluble fiber
sources and reduced risk of CHD. Thus, FDA is amending Sec.
101.81(c)(2)(ii)(A) to include barley betafiber derived from whole
barley flour, prepared as described in section II.B of this document,
as an additional source of beta-glucan soluble fiber.
The requirement in Sec. 101.81(c)(2)(iii)(A) states that a food
bearing the claim on its label include one of the ingredients listed
within Sec. 101.81(c)(2)(ii)(A) and that the ingredient provide at
least 0.75 gram of beta-glucan soluble fiber per reference amount
customarily consumed (RACC) of the food product. This level is based on
the minimum daily effective intake of beta-glucan soluble fiber from
barley betafiber and is the same as that which was previously found for
whole oat and dry milled barley sources of beta-glucan soluble fiber,
i.e., 3 g per day. FDA arrived at a value of 0.75 gram beta-glucan
soluble fiber per RACC based on a standard assumption that the daily
dietary intake is divided over four eating occasions per day (three
meals and a snack) (62 FR 3584 at 3592). Thus, adding barley betafiber
as an additional eligible source of beta-glucan soluble fiber will
further increase the type and number of qualifying food products and
make it easier for consumers to select barley and oat products at four
eating occasions per day. Thus, FDA is retaining under the ``Nature of
the food eligible to bear the claim'' section of the codified text of
this interim final rule, the criterion that foods eligible to bear the
claim contain at least 0.75 gram of soluble fiber (Sec.
101.81(c)(2)(iii)(A)(2)).
There is strong consistent scientific evidence that diets high in
saturated fat
[[Page 9944]]
and cholesterol are associated with elevated serum total and LDL
cholesterol, and that elevated serum cholesterol levels are a major
modifiable risk factor for CHD. Expert groups recommend lowering
dietary saturated fat and cholesterol as a primary lifestyle change for
reducing heart disease risk (Ref. 8). Comments to the 1997 oat beta-
glucan health claim final rule expressed concern that a CHD risk claim
that does not include a reference to a low saturated fat, low
cholesterol diet may mislead consumers into thinking that the single
food, e.g., oat products, would appear to be a ``magic bullet'' (62 FR
3584 at 3594). Further, based on the scientific evidence, the role of
soluble fiber from whole oats in the diet is generally recognized as
being of smaller magnitude in reducing CHD risk compared to consumption
of a low saturated fat, low cholesterol diet. When issuing the 1997 oat
beta-glucan health claim final rule, FDA concluded that although
selection of foods with soluble fiber from whole oats is a useful
adjunct to selection of diets low in saturated fat and cholesterol, in
reducing CHD risk, it would not be in the best interest of public
health nor consistent with the scientific evidence to imply that
selecting diets with soluble fiber from whole oats is a substitute for
consuming diets low in saturated fat and cholesterol (id.). Therefore,
FDA required in the 1997 oat beta-glucan health claim final rule that
the health claim statement include the phrase ``diets that are low in
saturated fat and cholesterol and that include soluble fiber from * *
*'' (Sec. 101.81(c)(2)(i)(A)). FDA reiterated this position and
extended it to soluble fiber from listed barley products when the
agency amended Sec. 101.81 to add whole grain barley and certain dry
milled barley products as eligible sources of beta-glucan soluble fiber
in 2005 (70 FR 76150 at 76156).
Beta-glucan soluble fiber from barley betafiber functions
comparably to beta-glucan soluble fiber from the listed oat and barley
sources in current Sec. 101.81(c)(2)(ii)(A) in its effect on reducing
LDL and total cholesterol. Barley betafiber, as a source of beta-glucan
soluble fiber, is a useful adjunct to selection of diets low in
saturated fat and cholesterol to reduce CHD risk. Thus, the agency is
requiring that the beta-glucan soluble fiber from barley betafiber
health claim be subject to the requirements in Sec.
101.81(c)(2)(i)(A). Including a reference to a low saturated fat, low
cholesterol diet in the health claim will enable the public to
understand the relative significance of the information in the context
of a total daily diet (21 U.S.C. 343(r)(3)(A)(iii)).
V. Description of Amendments to the Soluble Fiber from Certain Foods
and Risk of Coronary Heart Disease Health Claim Regulation
A. Nature of the Substance; Eligible Sources of Soluble Fiber
Section 101.81(c)(2)(ii) (nature of the substance) lists the types
and sources of soluble fiber that have been demonstrated to FDA's
satisfaction to have a relationship to a reduced risk of CHD. Section
101.81(c)(2)(ii)(A) lists beta-glucan soluble fiber from whole oat and
barley sources, along with specifying an AOAC INTERNATIONAL method of
analysis for beta-glucan soluble fibe, which will be used by FDA for
verifying compliance. Section 101.81(c)(2)(ii)(A)(1) through
(c)(2)(ii)(A)(5) identifies the whole oat and barley products that are
eligible sources of beta-glucan, i.e., oat bran, rolled oats, whole oat
flour, oatrim, whole grain barley, and dry milled barley.
FDA is amending Sec. 101.81(c)(2)(ii)(A) by adding Sec.
101.81(c)(2)(ii)(A)(6), which would specify barley betafiber as being
the ethanol isolated, soluble fraction of cellulase and alpha-amylase
hydrolyzed whole grain barley flour, with a beta-glucan content of at
least 70 percent on a dry weight basis (dwb). Thus, Sec.
101.81(c)(2)(ii)(A)(6) will read as follows ``Barley betafiber. Barley
betafiber is the ethanol precipitated soluble fraction of cellulase and
alpha-amylase hydrolyzed whole grain barley. Barley betafiber is
produced by hydrolysis of whole grain barley flour, as defined in
paragraph (c)(2)(ii)(A)(5) of this section, with a cellulase and alpha-
amylase enzyme preparation, to produce a clear aqueous extract that
contains mainly partially hydrolyzed beta-glucan and substantially
hydrolyzed starch. The soluble, partially hydrolyzed beta-glucan is
separated from the insoluble material by centrifugation, and after
removal of the insoluble material, the partially hydrolyzed beta-glucan
soluble fiber is separated from the other soluble compounds by
precipitation with ethanol. The product is then dried, milled and
sifted. Barley betafiber shall have a beta-glucan soluble fiber content
of at least 70 percent on a dry weight basis.''
B. Nature of the Food Eligible to Bear the Claim
Section 101.81(c)(2)(iii)(A)(2) (nature of the food) currently
states ``The food containing the oatrim from paragraph (c)(2)(ii)(A)(4)
of this section shall contain at least 0.75 g of beta-glucan soluble
fiber per reference amount customarily consumed of the food product;''
Because FDA is amending Sec. 101.81 to add barley betafiber, FDA
is amending Sec. 101.81(c)(2)(iii)(A)(2) as follows ``The food
containing the oatrim from paragraph (c)(2)(ii)(A)(4) of this section
or the barley betafiber from paragraph (c)(2)(ii)(A)(6) of this section
shall contain at least 0.75 g of beta-glucan soluble fiber per
reference amount customarily consumed of the food product;''
C. Other Requirements
All other requirements in Sec. 101.81(c)(1) through (c)(2)(i) and
the optional information in Sec. 101.81(d) will apply to the use of
the health claim authorized in Sec. 101.81 for barley betafiber-
containing products.
D. Model Health Claims
This interim final rule to amend existing Sec. 101.81(c)(2) does
not affect the model health claims specified in paragraph (e) of Sec.
101.81. Thus, the model health claims in Sec. 101.81(e) apply to a
claim about beta-glucan soluble fiber from barley betafiber and a
reduced risk of CHD.
VI. Analysis of Impacts
FDA has examined the impacts of this interim final rule under
Executive Order 12866 and the Regulatory Flexibility Act (5 U.S.C. 601-
612), and the Unfunded Mandates Reform Act of 1995 (Public Law 104-4).
Executive Order 12866 directs agencies to assess all costs and benefits
of available regulatory alternatives and, when regulation is necessary,
to select regulatory approaches that maximize net benefits (including
potential economic, environmental, public health and safety, and other
advantages; distributive impacts; and equity). The agency believes that
this interim final rule is not a significant regulatory action as
defined by the Executive order.
The Regulatory Flexibility Act requires agencies to analyze
regulatory options that would minimize any significant impact of a rule
on small entities. Because this interim final rule concerns voluntary
claims, the agency certifies that the interim final rule will not have
a significant economic impact on a substantial number of small
entities.
Section 202(a) of the Unfunded Mandates Reform Act of 1995 requires
that agencies prepare a written statement, which includes an assessment
of anticipated costs and benefits, before proposing ``any rule that
[[Page 9945]]
includes any Federal mandate that may result in the expenditure by
State, local, and tribal governments, in the aggregate, or by the
private sector, of $100,000,000 or more (adjusted annually for
inflation) in any one year.'' The current threshold after adjustment
for inflation is $127 million, using the most current (2006) Implicit
Price Deflator for the Gross Domestic Product. FDA does not expect this
interim final rule to result in any 1-year expenditure that would meet
or exceed this amount.
FDA has identified the following three options regarding this
petition: (1) Deny the petition; (2) authorize the petition (add only
barley betafiber to the ``Soluble fiber from certain foods and risk of
coronary heart disease health claim`` in Sec. 101.81 (the soluble
fiber and CHD health claim)); or (3) add barley betafiber to the
soluble fiber-CHD health claim and also expand the scope of the claim
to include all sources of soluble fiber. FDA concludes that authorizing
the petition by adding barley betafiber to the soluble fiber and CHD
health claim is the best option of those identified.
Option One: Deny the Petition
FDA can only define costs and benefits relative to a baseline. FDA
usually selects the option of taking no action as the baseline because
it helps readers identify the costs and benefits of actions that change
the status quo. In this case, denying the petition would correspond to
taking no action because it would imply no change in the soluble fiber
and CHD health claim and thus the continuation of the status quo. By
definition, the baseline itself has no costs or benefits. This does not
mean that we ignore the costs and benefits of the baseline. Instead, it
means that FDA expresses the costs and benefits of the baseline in how
it calculates the costs and benefits of the other regulatory options.
Option Two: Authorize the Petition (Add Only Barley Betafiber to the
Soluble Fiber and CHD Health Claim)
This option would allow producers who use barley betafiber to use
the soluble fiber and CHD health claim on their product labels under
certain conditions. Producers would only choose to change product
labels or reformulate products if they believe that the benefits that
they will derive from doing so are at least as great as the costs of
making those changes. FDA has reviewed the data supplied in the
petition and concludes that the claim is truthful and not misleading.
If this interim final rule is finalized without change, FDA can be sure
that to whatever extent producers use the claim, consumers will be in a
better position, assuming that more information that is truthful and
not misleading is always better for consumers. Based on this, FDA can
conclude that adding barley betafiber to the soluble fiber and CHD
health claim is better for social welfare than denying the petition.
Option Three: Add Barley Betafiber to the Soluble Fiber and CHD Health
Claim and Also Expand the Scope of the Claim to Include All Sources of
Soluble Fiber
This option would allow producers who use barley betafiber and all
other sources of soluble fiber to use the soluble fiber and CHD health
claim on their product labels under certain conditions rather than just
listing specific sources of soluble fiber. Similar to option two,
producers would only choose to change product labels or reformulate
products if they believed that the benefits that they will derive from
doing so are at least as great as the costs of making those changes. In
addition, this option would reduce the future burden on manufacturers
of petitioning FDA to use the soluble fiber and CHD health claim for
additional sources of soluble fiber, and it would also reduce the
agency's burden of evaluating each petition for each individual source
of soluble fiber. However, by expanding the use of the claim to all
sources of soluble fiber without reviewing the scientific data on each
source, FDA would not be able to verify that the claim was being used
under circumstances where it is truthful and not misleading to
consumers. If the expanded claim was used on a product that did not
reduce the risk of CHD, then the expanded claim could actually result
in an increase in CHD. This would happen if consumers were misled into
thinking that they were reducing their risk of CHD by consuming a
product that actually did not reduce the risk of CHD. As a result, they
might not take other beneficial steps that would decrease their risk of
CHD.
FDA cannot conclude that the cost savings of option three outweigh
the increased risk of a false or misleading claim being made under the
expanded claim. Therefore FDA cannot conclude that option three is
better for social welfare than option two. Moreover, the agency
believes that expanding the soluble fiber and CHD health claim to all
sources of soluble fiber without reviewing the scientific data
supporting such a claim of CHD risk reduction for each individual
source of fiber would be a failure to carry out our statutory
responsibility under section 403(r)(3)(B) of the act to issue health
claim regulations only when the agency determines that there is
significant scientific agreement that the claim is supported by the
totality of publicly available scientific evidence.
VII. Environmental Impact
The agency has determined under 21 CFR 25.32(p) that this action is
of a type that does not individually or cumulatively have a significant
effect on the human environment. Therefore, neither an environmental
assessment nor an environmental impact statement is required.
VIII. Paperwork Reduction Act of 1995
FDA concludes that the labeling provisions of this interim final
rule are not subject to review by the Office of Management and Budget
because they do not constitute a ``collection of information'' under
the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). Rather, the
food labeling health claim on the association between consumption of
barley betafiber beta-glucan soluble fiber and CHD risk is a ``public
disclosure of information originally supplied by the Federal Government
to the recipient for the purpose of disclosure to the public'' (see 5
CFR 1320.3(c)(2)).
IX. Federalism
FDA has analyzed this interim final rule in accordance with the
principles set forth in Executive Order 13132. FDA has determined that
the rule has a preemptive effect on State law. Section 4(a) of the
Executive order requires agencies to ``construe * * * a Federal statute
to preempt State law only where the statute contains an express
preemption provision or there is some other clear evidence that the
Congress intended preemption of State law, or where the exercise of
State authority conflicts with the exercise of Federal authority under
the Federal statute.'' Section 403A of the act (21 U.S.C. 343-1) is an
express preemption provision. Section 403A(a)(5) of the act provides
that ``* * * no State or political subdivision of a State may directly
or indirectly establish under any authority or continue in effect as to
any food in interstate commerce--* * * any requirement respecting any
claim of the type described in section 403(r)(1) of the act made in the
label or labeling of food that is not identical to the requirement of
section 403(r). * * *''
Currently, this provision operates to preempt States from imposing
health claim labeling requirements concerning beta-glucan soluble fiber
from barley betafiber and reduced risk of CHD because no such
requirement had been
[[Page 9946]]
imposed by FDA under section 403(r) of the act. This interim final
rule, if finalized without change, would amend existing food labeling
regulations to add barley betafiber as an eligible source of beta-
glucan soluble fiber to the authorized health claim for soluble fiber
from certain foods and risk of CHD. Although this rule would have a
preemptive effect in that it would preclude States from issuing any
health claim labeling requirements for beta-glucan soluble fiber from
barley betafiber and a reduced risk of CHD that are not identical to
those that would be required by this interim final rule, this
preemptive effect is consistent with what Congress set forth in section
403A of the act. Section 403A(a)(5) of the act displaces both State
legislative requirements and State common law duties. (Medtronic v.
Lohr, 518 U.S. 470, 503 (1996) (Breyer, J., concurring in part and
concurring in judgment); id. at 510 (O'Connor, J., joined by Rehnquist,
C.J., Scalia, J., and Thomas, J., concurring in part and dissenting in
part); Cipollone v. Liggett Group, Inc., 505 U.S. 504, 521 (1992)
(plurality opinion); id. at 548-49 (Scalia, J., joined by Thomas, J.,
concurring in judgment in part and dissenting in part).
FDA believes that the preemptive effect of this interim final rule,
if finalized without change, is consistent with Executive Order 13132.
Section 4(e) of the Executive order provides that ``when an agency
proposes to act through adjudication or rulemaking to preempt State
law, the agency shall provide all affected State and local officials
notice and an opportunity for appropriate participation in the
proceedings.'' FDA provided the States with an opportunity for
appropriate participation in this rulemaking on December 12, 2007, when
FDA's Division of Federal and State Relations provided notice via fax
and email transmission to State health commissioners, State agriculture
commissioners, food program directors, and drug program directors as
well as FDA field personnel of FDA's intent to amend the health claim
regulation authorizing health claims for soluble fiber from certain
foods and risk of CHD (Sec. 101.81). It advised the States of FDA's
possible action and encouraged the States and local governments to
review the petition and to provide any comments to the docket (Docket
No. 2006P-0393), until January 12, 2008. FDA received no comments in
response to the notice. FDA is also providing an opportunity for State
and local officials to comment on this interim final rule.
In conclusion, the agency has determined that the preemptive
effects of this interim final rule are consistent with Executive Order
13132.
X. Issuance of an Interim Final Rule and Immediate Effective Date
FDA is issuing this rule as an interim final rule, effective
immediately, with an opportunity for public comment. Section 403(r)(7)
of the act authorizes us to make proposed regulations issued under
section 403(r) of the act effective upon publication pending
consideration of public comment and publication of a final regulation,
if the agency determines that such action is necessary for public
health reasons. This authority enables us to act promptly on petitions
that provide for information that is necessary to: (1) Enable consumers
to develop and maintain healthy dietary practices, (2) enable consumers
to be informed promptly and effectively of important new knowledge
regarding nutritional and health benefits of food, or (3) ensure that
scientifically sound nutritional and health information is provided to
consumers as soon as possible. Proposed regulations made effective upon
publication under this authority are deemed to be final agency action
for purposes of judicial review. The legislative history indicates that
such regulations should be issued as interim final rules (H. Conf.
Rept. No. 105-399, at 98 (1997)).
We are satisfied that all three of the criteria in section
403(r)(7)(A) of the act have been met for the amendment to the soluble
fiber from certain foods and risk of CHD health claim to list barley
betafiber as eligible source of beta-glucan soluble fiber. This health
claim amendment will help enable consumers to develop and maintain
healthy dietary practices. The health claim will also provide consumers
with important knowledge regarding the effects of beta-glucan soluble
fiber in reducing the risk of, and will provide consumers with
scientifically sound information on the benefits of foods containing
beta-glucan soluble fiber from barley betafiber. Therefore, we are
using the authority given to us in section 403(r)(7)(A) of the act to
issue an interim final rule authorizing a health claim for soluble
fiber from barley betafiber and CHD, effective immediately.
FDA invites public comment on this interim final rule. The agency
will consider modifications to this interim final rule based on
comments made during the comment period. Interested persons may submit
