The balanced and varied diet in action

Health claims can be made in advertising  only if a statement indicating the importance of a varied and balanced diet (and a healthy lifestyle) is included, according to EC Regulation 1924/2006. Of course, a possibility – when TV commercials are concerned – is to add on-screen text. Increasingly, however, this is at least complemented by showing a balanced meal, generally a breakfast with fruit, juice, milk and, for example, toast. It is a visual statement to the same effect. Though we have seen little use of this approach in the food supplement sector, it is certainly interesting. Recently, UK’s ASA (the Advertising Standards Authority) has upheld a complaintagainst Danone’s Nutricia ad.

While the Authority agreed that Nutricia could not compare their product,  Cow & Gate Growing Up Milk, to other categories of food, it noted “the relevant EC Regulation [Reg. 1924/2006] did not prevent a child being depicted drinking Cow & Gate Growing Up Milk as an accompaniment to a meal, to clearly illustrate the importance of a varied mixed diet in which the product might be one element“. At the same time, a compaint has not been upheld against Ferrero’s Nutella saying on the importance of a varied diet statement: “the ad showed each child eating only one slice of toast with Nutella and that the images also included other breakfast items such as fruit juice, milk and cereal”.

A recent example, in this respect, can be viewed in Italy with Danone’ Danaos ad which, regardless of other comments, shows a balanced breakfast, with juice being poured, etc.

Low glycaemic “properties” claims: EFSA brings new hope

Low glycemic “properties” are an industry’s favorite when it comes to sports nutrition, particularly for bars. Though such claims are rather carelessly used in some EU countries, with little official scrutiny, there was concern that claims such as those would not be allowed under Reg. 1924/2006 or would fall outside its scope and hence in a limbo of regulatory uncertainty.

Although the recent batch of EFSA opinions on health claims resulted in several sadly negative opinions, sugar replacers such as xylitol, sorbitol, mannitol, maltitol, lactitol, isomalt, erythritol, D-tagatose, isomaltulose, sucralose and polydextrose came out as clear winners. EFSA’s NDA panel declared that “a cause and effect relationship has been established between the consumption of foods/drinks containing xylitol, sorbitol, mannitol, maltitol, lactitol, isomalt, erythritol, D-tagatose, isomaltulose, sucralose or polydextrose instead of sugar and reduction in post-prandial blood glucose responses (without disproportionally increasing post-prandial insulinaemic responses) as compared to sugar-containing foods/drinks“.

The Panel was apparently convinced that the Regulation’s restrictions on comparative claims as well as art. 3 (“...the use of nutrition and health claims shall not….give rise to doubt about the safety and/or the nutritional adequacy of other foods“, with sugar possibly the loser in this case) did not present a problem, although this may come back at the enforcement level in Member States.

In practice, while the immediate implications of this EFSA opinion vary in different Member States, there is a clear possibility of making “low glycemic” claims on food supplements (e.g., protein with sucralose) and bars with polyols (news which will make many happy).

However, the conditions set by the Panel deserve a careful analysis before using the claims.

EFSA: caffeine for sports ok, but not for weight loss

The 8 of April 2011 EFSA’s NDA Panel has published the outcome of the evaluations of a fourth series of ‘general function’ health claims proposed for use on food products.

Only few opinions are positive for sports nutrition. Among these 442 health claims, the most relevant are related to caffeine; in particular  health claims such as ‘Increased alertness’ , ‘ increased attention’, ‘increase in endurance performance’, ‘increase in endurance capacity’, ‘reduction in the rated perceived exertion/effort during exercise’ are now accepted for caffeine. Other positive outcomes are related to resistant maltodextrins ( ‘Changes in bowel function’), Choline (‘ Contribution to normal lipid metabolism ‘) and olive poliphenols  ( ‘Hydroxytyrosol protects LDL particles from oxidative damage’).

Instead most EFSA opinions are negative. It should be noted that all the health claims on ‘reduction of body weight’ related to caffeine and green tea have been rejected. Other negative outcomes are related to several aminoacids such as  L-Arginine, Lysine, Tryptophan and aminoacidic derivatives such as Taurine and Carnosine, particularly interesting are the rejected health claims concerning  ‘management of body mass’  and “improvement of endothelium-dependent vasodilation’ (Arginine),  ‘Contribution to normal protein synthesis’ (Lysine), ‘Maintenance of normal muscle function’ (Taurin). Also Quercetin, Lutein, Alpha Linoleic Acid (ALA), FOS and PUFAs DHA/EPA (Omega 3) received general negative opinions from the Panel.

“The positive opinion on caffeine is important specifically for the benefits which EFSA has recognized within the domain of the Nutrition and Health Claims Regulation, and the standard that it sets.” commented Luca Bucchini, managing director of Hylobates “Though EFSA’s opinions are important when thinking to new products, they should not be the only driving force. EFSA’s processs is welcome when compared to the less than transparent situation in several EU countries; at the same time, it should be noted that EFSA’s approach has been less than consistent between micronutrients and other substances. It is time for the sports nutrition industry to think carefully about the future.”

EFSA: la caffeina per lo sport funziona, altre sostanze no

In data odierna il gruppo di esperti dell’EFSA ha pubblicato i risultati della valutazione di 442 claim sulla salute proposti per l’uso nei prodotti alimentari.

Solo poche opinioni possono essere considerate positive nel campo della nutrizione sportiva,  in particolare sono stati accettati claim relativi al consumo di caffeina e aumento dello stato di allerta/attenzione, diminuzione della percezione dello sforzo durante l’esercizio fisico ed aumento della capacità in esercizi fisici di resistenza. Gli esperti dell’EFSA hanno dato inoltre parere positivo per il claim relativo alle maltodestrine resistenti affermando che c’è una relazione di causa effetto tra il consumo di questi carboidrati e il miglioramento della funzionalità intestinale. Altri esiti positivi sono riscontrabili per claim relativi alla Colina (‘contribuisce al normale metabolismo lipidico’) e ai polifenoli dell’ulivo (‘Idrossitirosolo protegge le LDL dal danno ossidativo’).

Gran parte dei claim valutati sono stati respinti, tra cui i principali relativi al consumo di caffeina e tè verde che riguardano ‘mantenimento e controllo del peso corporeo’ non potranno più essere utilizzati per prodotti ed integratori alimentari, a meno che il processo a livello comunitario abbia un esito diverso e solo quando i pareri diventeranno legge, con lo specifico regolamento di attuazione. Nessun parere positivo per quel che riguarda i claim  sugli aminoacidi come arginina, lisina, triptofano e derivati aminoacidici quali taurina, carnosina: infatti i principali claim sulla massa muscolare, attività di tipo tonico e vasodilatazione sono stati bocciati.Numerosi altri claim sono stati valutati e bocciati, in particolare molti relativi a Quercetina, Luteina, Acido Alfa Linoleico (ALA), FOS e i PUPA DHA/EPA (Omega 3) generalmente per carenza di dati sufficienti.

“Non bisogna dimenticare che EFSA ha ampiamente riconosciuto i benefici di vitamina e minerali che sono i tipici principi degli integratori alimentari, anche per lo sport (come per vitamina C e sistema immunitario dello sportivo)” ha commentato Luca Bucchini, direttore gestionale di Hylobates “Per le altre sostanze ha usato uno standard di prova molto diverso e a volte discutibile, anche se riteniamo un processo trasparente e scientificamente qualificato come quello di EFSA sia importante e necessario. Il riconoscimento per la caffeina è importante ed univoco; sarà importante bilanciare l’effetto positivo dei pareri EFSA con la necessità di portare sul mercato prodotti equilibrati, indirizzando attentamente la ricerca. Su un piano più squisitamente tecnico è importante, che con l’opinione sulla caffeina, EFSA ha confermato la possibilità di claim sulla salute nel quadro del Regolamento 1924/2006 riferiti ad attività sportive”.

Le indicazioni fornite dal Ministero della Salute sul proprio sito, fino all’entrata in vigore di un regolamento applicativo (atteso per metà 2012), restano permesse.

ARNOLD HIGHLIGHTS: QUERCETIN, A POWERFUL, NOT FULLY EXPLOITED NATURAL ANTIOXIDANT

Quercetin, a member of the flavonoids family, is one of the most important dietary antioxidants. It is widely present in foods including vegetables, fruit, tea and wine and is claimed to exert beneficial health effects.

Especially the ability of Quercetin to scavenge highly reactive species such as peroxynitrite and the hydroxyl radical probably has beneficial health effects.

At Arnold, we saw a complete product line based on fortification with quercetin, with energy drinks, soft chews, liquid concentrates and powder drinks.

On April 8 2011 EFSA published a new opinion concerning quercetin, rejecting the health claim ‘ Quercetin contributes to the protection of DNA, proteins and lipids from oxidative damage’, concluding that a cause and effect relationship has not been established between the consumption of quercetin and protection of DNA, proteins or lipids from oxidative damage. This makes quercetin less attractive as a food supplement ingredient.  (Updated 11/04/2011 with EFSA opinion)

Astaxanthin: a new remedy against oxidative stress in muscle?

Astaxanthin is a natural pigment content in algae Haematococcus pluvialis, which might have some good antioxidant properties. In this regard, the scientific community is not unanimous: some studies (e.g., Aoi et al, 2007) put the focus on a potential antioxidant effect which has a positive impact on muscle health; on the other hand other studies (Bloomer et al, 2005) suggest that astaxanthin supplementation does not benefit the muscle, because it does not reduce the risk of muscle damage.

The Italian Health Ministry accepts that astaxanthin has antioxidant properties and does not place restrictions on its use; but at European level, EFSA gave a negative opinion concerning a number of health claims for astxanthin including maintenance of normal joints, tendons or connective tissue, and protection of DNA, proteins or lipids from oxidative damage.
Use of the substance in sports nutrition may be increasing: recently, GNC has used astaxanthin with β-alanine, to create a blend named ‘Muscle Buffering System ‘, included in formulations of the new line of products ‘GNC Beyond Raw’.
Use of astaxanthin in the formulation of products should be carefully evaluated.

Hylobates experience? Wonderful mix!

A training stage that introduces in job’s world is undoubtedly an important milestone for a new graduate, but even more so is the ability to carry out in Hylobates Consulting, leading company in Italy that offers the most advanced scientific and regulatory applied knowledge in food safety, on labeling and health claims for food supplements, dietetic products and common foods, as well as regulatory dossiers on ingredients and claims.

The atmosphere that you live every day is very friendly, warm and dynamic at the same time, in fact no one lies on the results obtained so far but on the contrary there is a strong ambition that drives everyone to improve.
For a graduate in biology, this stage represents on the one hand the natural continuation of his studies and the possibility to apply them, because the knowledge on biological macromolecules, physiological and metabolic pathways is essential in the job, On the other hand opens up a whole new world unknown but equally interesting that addresses regulatory and legislative issues on the basis of food safety.

Further fundamental aspect to note is that everyone, including newcomers, have a voice, and final decisions are taken by mutual agreement.

The experience can be considered highly educational due to the large number of areas that covers: biology, knowledge of regulations and problem solving, a complex and attractive mix.
