What are the advantages of iron in food?

Answer

Iron, a mineral, functions primarily as a carrier of oxygen in the body, both as a part of hemoglobin in the blood, and of myoglobin in the muscles. It also aids the immune system and the central nervous system. Its primary use is, however; to deliver oxygen throughout the body; a vital process.

Vitamin C helps to absorb iron, and the iron in fish and meat is more readily absorbed than those in other foods. At the same time, the iron that can be found in foods is not harmful, whereas synthetic iron cannot be absorbed properly and can result in an easy overdose (especially in men).
