Aim for five servings a day. Many fruits and vegetables contain vitamin C, which helps your body absorb iron. Although these foods and drinks are good sources of calcium, they do not supply a lot of iron. The exceptions are tofu, breast milk, and infant formulas. Iron in meats, fish, and poultry is used especially well by the body. Meat, eggs, dried beans, and nuts have slightly more iron than poultry and fish. Dark meats have more iron than light meats. Liver is one concentrated source of iron. Choose lean meats to limit your intake of saturated fat.
