Nutritional fortification is the process of adding essential vitamins and minerals to food products to improve their nutritional value. This practice aims to prevent nutrient deficiencies in populations, especially in areas where certain nutrients may be lacking in the diet. Common examples include adding iron to flour or iodine to salt. Fortification can be done at various levels, including home, community, or industrial scales. It is often implemented by governments or food manufacturers to enhance public health. By increasing the nutrient content of commonly consumed foods, nutritional fortification helps support overall health and well-being in communities.
