From 1 of July 2007 takes in effect the new EU legistation on health and nutrition claims on food. The Regulation aims to
ensure that consumers are not misled by unsubstantiated, exaggerated or
untruthful claims about foodstuffs. With the new legislation, consumers will be
able to rely on clearer and more accurate information on food labels, enabling
them to be properly informed on the food they choose. Nutrition claims are
those used on labels or in advertising/marketing campaigns, which make an
assertion about a particular nutritional property of a food. Examples include
"high in vitamin C", "low fat", "no added
sugar"and "high fibre".

From 1 of Januar 2008 some health claims
– disease risk reduction claims and claims referring to the health of children
– authorisation will be required on a case-by-case basis, following the
submission of a scientific dossier to the European Food Safety Authority (EFSA)
for assessment. Likewise, health claims based on new scientific data will have
to be submitted to EFSA for evaluation before they can be authorised for use.
