The appearance of fortified foods is similar to that of conventional foods (e.g. yoghurts, juices). They differ from these only in that nutritionally active substances such as vitamins, minerals, fatty acids or other nutrients are added. Regulation (EC) No 1925/2006 of the European Union on the addition of vitamins and minerals and of certain other substances to foods also applies to the fortification of foods in Belgium. The following foods must not be fortified with vitamins and minerals: - unprocessed foodstuffs, including fruit, vegetables, meat, poultry and fish; - alcoholic beverages (< 1.2% alcohol), with the exception of protected traditional wine recipes marketed be-fore the adoption of the EU Regulation on fortified foods (20 December 2006) and which have been noti-fied to the Commission However, due to transitional measures laid down in the regulation, national regulations, such as Royal Decree of 30 May 2021 on the placing on the market of nutrients and foodstuffs to which nutrients have been added. Tijs Royal Decree sets minimum and maximum levels for the addition of certain micronutrients to food (they are different from those set for food supplements). In addition a pre-marketing notification procedure is imposed, for each fortified food marketed in Belgium.
