Fortification is the deliberate addition of vitamins and minerals to a product to increase its nutritional quality and give a public health benefit with low risk.
Micronutrients added to staples and condiments help avoid large-scale deficiency disorders in regions where the soil or staple foods lack nutrients.
The FAO lists cereals and cereal-based goods, milk and dairy products, fats and oils, accessory foods, tea and other beverages,
Food fortification can also be classed by addition stage: Industry fortification, Biofortification, Vitamin D home fortification
