Successful Health

Claims: Challenges for

Natural (Whole Foods)

“Natural”

“Botanical” – “Food Herbal”

•The situation is still not clear what will happen to these (800+) claims

related mainly to their background of traditional use

•Both EFSA and the Commission have to decide and

regulation is at member state level on case by case basis

“Natural”

•Generally refers to foods from primary production, i.e. whole foods

and their basic preparation

•Regulation (EC) No 1924/2006 applies to these products

Key Points for a Successful Health Claims

Submission

Healthy Claim Application

1) Clarity in claim

Wording*

2) Food/ constituent is characterised*

3) Transparent, comprehensive

literature search*

4) High quality human

studies*

5) Study population relevant* 6) Valid

outcome measures*

7) Biologically relevant

magnitude of effect

8) Consistency

9) Statistical significance

10) Other causality criteria

* Especially

challenging for

natural/whole

foods

1) Clarity in Claim Wording

versus

“An apple a day keeps the

doctor away”?

(not specific enough)

“Apple juice contains vitamin

C. Vitamin C contributes to

maintain the normal function

of the immune system.”

(Article 13)

2) Food Constituent is Characterised

Characterising whole foods/botanical foods give rise to tremendous variation

• “Walnuts are seeds from the walnut tree (genus Juglans) of which about 20 different

species are known in different parts of the world. Walnuts are drupes, rather than nuts.

• One of the most popular varieties of walnut is the Persian or English walnut, which has

a large seed and a thinner shell, yielding more edible walnut meat by weight than

other species. Black walnuts are another commonly sold walnut species, as are white

walnuts, also called butternuts.

• The nut kernels contain about 57-65 % fat, of which about 3-6 % are saturated fatty

acids (SFAs), 9-15 % are monounsaturated fatty acids (MUFAs), and 35-47 % are

polyunsaturated fatty acids (PUFAs) (33-38 % linoleic acid (LA), and 2-9 % alpha-

linolenic acid (ALA)). The nut kernels also contain about 5-7 % fibre, of which about 25

% is soluble fibre, 15-29 % protein, and small amounts of plant sterols and other

phytochemicals.

• The Panel notes the variation in terms of macronutrient composition between different

types of walnuts.”

Example: Cranberry Extract

Standardisation of bioactives is easier for extracts

Example of how cranberry extract is standardised: to PAC

content:

“The food that is the subject of the health claim is the cranberry extract

and D-mannose containing food supplement Uroval® According to a

conformity declaration for “Uroval® manosa”, one tablet, coated with a

polymer film agent, a hydroxyl-propylmethylcelullose, contains 300 mg

of D(+)-mannose and 100 mg of “cranberry extract” with 10%

proanthocyanidins, and the additives talc (5 mg), microcrystalline

cellulose (90 mg) and magnesium stearate (5 mg). According to a

certificate of analysis issued by the Chinese company Dalian Hongjiu

Biotech Co Ltd., the botanical source of the ethanol/water- extracted

cranberry powder is Vaccinum macrocarpon L.”

3) Transparent, Comprehensive Literature Search

Literature search must be systematic, comprehensive,

transparent, reproducible, and properly documented.

For natural/whole foods, how do you conduct a meaningful

literature search on such wide criteria? Characterisation of the

food defines what you search for.

A search on “Milk and Bone” reveals 1000+ initial individual

publications.

4) High Quality Human Studies

High quality double blind placebo-controlled studies are more

often focussed on single components and/or well

characterised/defined ones within more complex foods

Whilst there may be many studies for whole foods and

botanicals that are traditionally consumed there are usually

very few high quality studies

• What is an appropriate control for a whole food?

• What is the expectation for blinding in whole food studies? Although

single-blinding is achievable, many whole food studies are not blinded.

4) High Quality Human Studies

Walnuts – endothelium-mediated vasodilation

“In weighing the evidence, the Panel took into account that one

intervention study in healthy subjects, adequately powered and

controlled, showed a sustained effect of the consumption of walnuts

on endothelium-dependent vasodilation, that the results of one

additional intervention study in type 2 diabetic subjects on blood

pressure-lowering, cholesterol-lowering, and/or oral antidiabetic

medication are consistent with these findings, and that an acute

intervention study also showed a positive effect of the consumption of

walnuts on endothelium-mediated vasodilation.”

www.intertek.com 10

5) Study Population Relevant

Target populations can be extremely wide in some cases

(e.g., apple) or geographically narrow in others (e.g.,

baobab, monkfruit), in particular for traditional use claims.

Estimations of population exposure for risk reduction claims

based on epidemiological data will vary considerably.

Populations studied must be relevant to target populations.

Caution should be exercised in relying on studies in subjects

with disease. EFSA reviews these on a case-by-case basis.

www.intertek.com 11

6) Valid Outcome Measures

There may be several valid outcome measures depending on

the nutritional complexity of the product and claimed effect:

Versus

Applicants should consult EFSA’s guidance documents to gain

perspective on the outcome measures and methods used to

assess the outcome measures that are considered acceptable

by EFSA.

“Keeps the doctor away”

(traditional use)

“Results in a significant decrease in risk of incidence of the

common cold”

(scientifically validated)

www.intertek.com 12

Other Causality Criteria

• Magnitude of effect – statistically and clinically significant

• Consistency

• Dose response

• Biological plausibility/mechanism

• Specificity

• Temporality

These causality criteria can be difficult to establish

given the complexity of test article as a natural/whole

food.

Disease Risk Reduction (Article 14)

To date there are no approved disease risk (factor)

reduction claims for whole or natural foods themselves

www.intertek.com 20

Do we Need Claims on These Foods?

Is there a need to make specific health claims for all whole,

natural or “super" foods themselves?

Whole foods can in a number of cases make more indirect

nutrient claims based on their composition than would be shown

for the whole food in many expensive placebo-controlled studies
