There are two types: heme and nonheme. Heme iron is found in meat and fish, while nonheme is in certain leafy greens and iron-fortified grains, such as breakfast cereals. Meat eaters have an easier time getting their daily dose of iron because heme iron is more easily absorbed into the body. Thatâs why the Food and Nutrition Board at the National Academy of Sciences recommends that vegetarians consume nearly two times more iron each day than people who eat meat.
Iron in plant foods such as lentils, beans, and spinach is nonheme iron. This is the form of iron added to iron-enriched and iron-fortified foods. Our bodies are less efficient at absorbing nonheme iron, but most dietary iron is nonheme iron.1  1.ron-Rich Foods.
