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.
There are two forms of iron found in food: heme and non-heme. Heme iron, which is in meat, fish and poultry, is absorbed two to three times more efficiently than non-heme iron. Whole grains, legumes, fruits and vegetables all contain non-heme iron. To lower levels of iron, limit the heme-containing foods you eat. Legumes and beans make good choices for alternative sources of protein because they're high in protein and the iron they contain is not easily absorbed.
