Food fortification or enrichment is the process of adding micronutrients to food. It can be carried out by food manufacturers, or by governments as a public health policy which aims to reduce the number of people with dietary deficiencies within a population. Fortification is the addition of key vitamins and minerals such as iron, iodine, zinc, Vitamin A & D to staple foods such as rice, milk and salt to improve their nutritional content. These nutrients may or may not have been originally present in the food before processing. Iron, zinc, folic acid, and other B vitamins are commonly added to prevent anemia from nutritional deficiencies and reduce the risk of infants with severe brain and spine birth defects known as neural tube defects. Fortification benefits individuals at every point in life - from conception to aging.
