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 has two dietary forms -- heme and non-heme. Heme iron comes from hemoglobin in red blood cells; therefore, only animal products contain heme iron. Plant foods supply non-heme iron, which has a different chemical structure. Non-heme is also the type added to iron-fortified foods and beverages.
