Iron deficiency, especially iron deficiency anemia, is a common problem worldwide, affecting groups like infants, children, and women of reproductive age. Low intake of iron-rich foods is a major cause. To address this, many countries have programs to provide iron supplements or fortify foods with iron. Pregnant women, in particular, need extra iron and are often advised to take supplements. Food fortification can target specific groups, like infants or the general population, by adding iron to staple foods or condiments.
