Foods which are produced for vegans , such as soya products, are often fortified with vitamin B 12 . As foods from plant sources do not contain this vitamin, fortified foods are the only dietary source of vitamin B 12 for vegans. Some soya drink products are also fortified with calcium. Many manufactured foods for infants are fortified, particularly with iron and some with vitamin D. Other foods, such as meal replacements, sports drinks, slimming products, and foods aimed at particular groups, are often fortified. The nutrients contained in these foods can make an important contribution to the diets of people who eat them.
Claims usually use such terms as 'low', 'high' and 'source of'.
Claims can be used for fortified foods, foods which are naturally high in different nutrients, and also for foods which have been modified to contain less of certain nutrients. If a manufacturer makes a claim about a nutrient, nutrition information must be provided on the food label . In the UK, all claims made about a food must comply with the Food Safety Act 1990. This states that it is an offence to falsely describe a food. In addition, the Food Labelling Regulations 1996 define criteria which must be met if a manufacturer wishes to make a claim about the energy, protein, cholesterol, vitamin or mineral content of a food.
