Probably the best known nutrition fact about iron is that meatsâparticularly red meatsâare rich in iron. You will see some familiar animal foods on our list of iron sources below. While this is true, it is also true that a number of plant foods are also rich in iron.
Iron found in foods is either in the form of heme or non-heme iron. Heme iron is better absorbed than non-heme iron. Foods containing heme iron are the best for increasing or maintaining healthy iron levels. Such foods include (in order of iron-richness) clams, oysters, organ meats, beef, pork, poultry, and fish.
