In December 2006, a Regulation on the use of nutrition and health claims for foods was adopted by the Council and Parliament. This Regulation lays down harmonised rules for the use of health or nutritional claims (such as “low fat”, “high fibre” and “helps lower cholesterol”) on foodstuffs based on nutrient profiles.
The Regulation on nutrition and health claims will ensure that any claim made on a food label in the EU is clear, accurate and based on generally accepted scientific evidence. In doing so, it will enable consumers to make informed and meaningful choices when it comes to food and drinks. This should also contribute to a higher level of human health protection, as it ties in with the Commissions campaign for healthier lifestyle choices.
The Regulation also aims to ensure fair competition and promote and protect innovation in the area of food. Finally, the Regulation will facilitate the free circulation of products bearing claims in the European Union.
Regulation on Health and Nutritional Claims
The Standing Committee on the food chain and animal health approved the conclusions formulated in a Guidance on the implementation of Regulation (EC) N° 1924/2006 on nutrition and health claims made on foods on 14 December 2007.
The Commission will establish and maintain a Community Register; the Register will include the lists of both authorised and rejected health claims, as well as nutrition claims. Unless an exclusive right of use is provided for, on the basis of proprietary data, any food business operator who can ensure fulfilment of the conditions of use set for the authorised health claims may use them in the presentation, marketing or labelling of their products.
