Vitamins And Minerals: Iron And Zinc

Iron and zinc are essential minerals that the human body needs to function. They are naturally found in many foods like meat, fish, beans, and whole grains. In processed foods, they are often added in purified forms, such as iron sulfate or zinc oxide, to boost nutritional value.

Manufacturers add iron and zinc to foods, especially cereals and snacks, to fortify them and help consumers meet their daily recommended intake. This is a common practice for products marketed to children and families. They do not significantly alter the taste or texture of the food.

Iron and zinc are essential nutrients. The US National Academies have established Tolerable Upper Intake Levels (ULs) for these minerals. JECFA and EFSA have also evaluated iron and zinc compounds. Excessive iron intake can lead to gastrointestinal upset, while very high zinc intake can interfere with copper absorption. However, the amounts added to fortified foods are generally considered safe and beneficial for preventing deficiencies.
