    Iron is a mineral found in every cell of the body. Iron is considered an essential mineral because

    it is needed to make part of blood cells .function The human body needs iron to make theoxygen-carrying proteinshemoglobinand myoglobin. Hemoglobin is found in red blood cells

    and myoglobin is found in muscles.Iron also makes up part of many proteins in the

    body.Food SourcesThe best sources of iron include:

    Eggs (especially egg yolks) Iron-fortified cereals Liver Lean red meat (especially beef) Oysters Poultry, dark red meat Salmon Tuna Whole grains Reasonable amounts of iron are also found in lamb, pork, and shellfish.Iron

    from vegetables, fruits, grains, and supplements is harder for the body to absorb. These

    sources include:

    Dried fruitso pruneso raisinso apricots

    Legumeso lima beanso soybeanso dried beans and peaso kidney beans

    IRON RICH DIET

    o milleto oatso brown rice

    If you mix some lean meat, fish, or poultry with beans or dark leafy greens at a meal, you can

    improve absorption of vegetable sources of iron up to three times. Foods rich in vitamin Calsoincrease iron absorption.Some foods reduce iron absorption. For example, commercial black or

    pekoe teas contain substances that bind to iron so it cannot be used by the body.Side

    Effects. LOW IRON LEVELSThe human body stores some iron to replace any that islost. However, low iron levels over a long period of time can lead to iron deficiency anemia.

    Symptoms include lack of energy, shortness of breath, headache, irritability,dizziness, or weight

    loss. For more details on this condition seeiron deficiency anemia.Those at risk for low ironlevels include:

    Women who are menstruating, especially if they have heavy periods

    Women who are pregnant or who have just had a baby Long-distance runners Strict vegetarians People with any type of bleeding in the intestines (for example, a bleeding ulcer) People who frequently donate blood People with gastrointestinal conditions that make it hard to absorb nutrients from food

    Babies and young children are at risk for low iron levels if they do not receive the appropriate

    foods. Babies moving to solid foods should eat iron-rich foods. Infants are born with enough iron

    to last about six months. An infant's additional iron needs are met by breast milk. Infants that arenot breastfed should be given an iron supplement or iron-fortified infant formula. Children

    between age 1 and 4 grow rapidly, which uses up iron in the body. They should be given iron-fortified foods or iron supplements. Note: Milk is a very poor source of iron. Children who drinklarge quantities of milk and avoid other foods may develop "milk anemia." Recommended milk

    intake is two to three cups per day for toddlers. Adolescents are more prone to low iron levels

    because of rapid growth rates and inconsistent eating habits. TOO MUCH IRON-The geneticdisorder calledhemochromatosisaffects the body's ability to control how much iron is absorbed.

    This leads to too much iron in the body. Treatment consists of a low-iron diet, no iron

    supplements, and phlebotomy (blood removal) on a regular basis..It is unlikely that a person

    would take too much iron. However, children can sometimes develop iron poisoning byswallowing too many iron supplements. Symptoms of iron poisoning include:

    Fatigue Anorexia Dizziness Nausea Vomiting Headache Weight loss Shortness of breath

    Females

    9 to 13 years: 8 mg/day 14 to 18 years: 15 mg/day 19 to 50 years: 18 mg/day 51 and older: 8 mg/day

    Women who are pregnant or producing breast milk may need different amounts of iron. Ask

    your health care provider what is appropriate for you. References-Trumbo P, Yates AA,Schlicker S, Poos M. Food and Nutrition Board, Institute of Medicine, T Iron-Rich Foods. Spinach

    may not give you superhuman strength to fight off villains like Popeye's nemesis Bluto, but this leafygreen and other foods containing iron can help you fight a different type of enemy -- iron-deficiency

    anemia. Iron-deficiency anemia, the most common form of anemia, is a decrease in the number of red

    blood cells caused by too little iron. Without sufficient iron, your body can't produce enough

    hemoglobin, a substance in red blood ce

    lls that makes it

    possible for them to carry oxygen to the body's tissues. As a result, you may feel weak, tired, and

    IRON RICH DIET

    irritable.About 20% of women, 50% ofpregnantwomen, and 3% of men do not have enough iron in

    their body. The solution, in many cases, is to consume more foods high in iron. How Your Body Uses

    Iron in Food. When you eat food with iron, iron is absorbed into your body mainly through the upper

    part of your small intestine. There are two forms of dietary iron: heme and nonheme. Heme iron is

    derived from hemoglobin. It is found in animal foods that originally contained hemoglobin, such as red

    meats, fish, and poultry. Your body absorbs the most iron from heme sources. Iron-Rich Foods. Very

    good sources of heme iron, with 3.5 milligrams or more per serving, include:

    3 ounces of beef or chicken liver 3 ounces of clams, mollusks, or mussels 3 ounces of oysters

    Good sources of heme iron, with 2.1 milligrams or more per serving, include:

    3 ounces of cooked beef 3 ounces of canned sardines, canned in oil 3 ounces of cooked turkey

    Other sources of heme iron, with 0.7 milligrams or more per serving, include:

    3 ounces of chicken 3 ounces of halibut, haddock, perch, salmon, or tuna 3 ounces of ham 3 ounces of veal

    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.Very good sources of nonheme iron, with

    3.5 milligrams or more per serving, include:

    Breakfastcereals enriched with iron One cup of cooked beans One-half cup of tofu 1 ounce of pumpkin, sesame, or squash seeds

    Good sources of nonheme iron, with 2.1 milligrams or more per serving, include:

    One-half cup of canned lima beans, red kidney beans, chickpeas, or split peas One cup of dried apricots One medium baked potato One medium stalk of broccoli One cup of cooked enriched egg noodles One-fourth cup of wheat germ

    Other sources of nonheme iron, with 0.7 milligrams or more, include:
