Fortified foods are products to which nutrients, vitamins or other important substances are added during processing to increase the nutritional or biological value. These foods are used for a variety of purposes, such as replacing lost nutrients, substituting similar foods for nutritional value, or increasing nutrient content. Although a varied diet could be a sufficient source of nutrients, in many cases it does not provide optimal intakes of vitamins and minerals. Fortified foods must meet certain criteria, including the presence of significant amounts of vitamins and minerals and the method of administration. However, it is also important to consider the adverse effects of excessive intake. EU regulations regulate the composition and labelling of fortified foods to inform consumers about the amount of nutrients consumed and the overall nutritional value of the product. The regulations also ensure that other ingredients are used safely and appropriately in foods. Hungary doesn’t specifically regulate fortified foods at national level, but acts in line with EU regulations and transposes them into its own legislation.
