Good Food Sources of Iron

Image for iron Many people, especially women of childbearing age, infants, and pregnant women, may not take in as much iron as they need. However, there are many good food sources of iron to choose from. If your doctor advises you to increase your iron intake, consult the chart below to determine how much you need, and read on for some suggestions to meet those needs.

Here's Why:

Your blood depends on iron to help it carry oxygen through the body. In some cases, anemia is caused by a lack of iron in the diet. Iron also helps your body to fight infection and to make collagen, which is the major protein that makes up connective tissue, cartilage, and bone. Other medical conditions may be worsened if you do not have enough iron.

Here's How:

Iron exists in two forms—heme and nonheme. Heme iron is part of the hemoglobin and myoglobin molecules in animal tissues. It is found in meat and other animal sources. About 40% of the iron in meat is in the heme form. Nonheme iron comes from animal tissues other than hemoglobin and myoglobin and from plant tissues. It is found in meats, eggs, milk, vegetables, grains, and other plant foods. The body absorbs heme iron much more efficiently than nonheme iron.

Tips For Increasing Your Iron Intake

The amount of iron your body absorbs varies depending on several factors. For example, your body will absorb more iron from foods when your iron stores are low and will absorb less when stores are sufficient. In addition, certain dietary factors affect absorption:
