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 dietary iron: heme and nonheme. Heme iron is derived from hemoglobin, the protein in red blood cells that delivers oxygen to cells. Heme iron is found in animal foods that originally contained hemoglobin, such as red meats, fish, and poultry.
