Fortification commonly uses staple foods as vehicles to deliver
micronutrients generally lacking or not contained in
sufficient concentration in the diet of a population and
has been practiced since the 1930s to target specific health
conditions such as iodine deficiency through the
iodisation of salt, anaemia through the fortification of
cereals with iron and vitamins, and neural tube defects
through the fortification of wheat flour with folic acid.
