Iron is
an important trace mineral that is found in every cell of the body,
usually combined with protein. Iron is an essential mineral for
humans because it is part of blood cells. About 30% of the iron in the
human body is in storage to be readily available to replace any that
is lost.
Iron is
essential to the formation of hemoglobin and myoglobin, which carry
oxygen in the blood and muscles. It also makes up part of many proteins
and enzymes in the body.
Food Sources
The best
food sources of easily absorbed iron are animal products, which contain
heme iron. Iron from vegetables, fruits, grains, and supplements (non-heme
iron) is harder for the body to absorb. 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 C
also increase iron absorption.

Some foods decrease
iron absorption. Commercial black or pekoe teas contain substances that bind
to iron so it cannot be used by the body.
Consider the
amount of absorbable iron in a food, not just the total iron content. Iron
sources that have high iron availability include the following:
-
Oysters
-
Liver
-
Lean red meat (especially beef)
-
Poultry, dark red meat
-
Tuna
-
Salmon
-
Iron-fortified cereals
-
Dried beans
-
Whole grains
-
Eggs (especially egg yolks)
-
Dried fruits
-
Dark leafy green vegetables
Reasonable amounts
of iron are also found in lamb, pork, and shellfish. Non-heme iron is found
in the following:
-
Whole grains
-
wheat
-
millet
-
oats
-
brown rice
-
Legumes
-
lima beans
-
soybeans
-
dried beans and peas
-
kidney beans
-
Seeds
-
Dried fruits
-
Vegetables
Side Effects
Iron deficiency
most commonly manifests itself as iron deficiency anemia. Iron deficiency
and iron deficiency anemia can occur during periods of rapid growth, during
pregnancy, and among women who are menstruating more than usual. It can also
be associated with any type of intestinal loss of blood, frequent donation
of blood, and from the inability to absorb iron efficiently.
Initial symptoms
of iron deficiency anemia include the following:
-
Fatigue
-
Lack of energy
-
Dizziness
Weight loss and
lowered immunity may also indicate iron deficiency. The symptoms can be alleviated
once the cause of the iron deficiency has been determined.
It is unlikely
that iron toxicity can develop from an increased dietary intake of iron alone.
Children have been known to develop iron toxicity by increased intake of iron
supplements, however. Symptoms of iron toxicity include the following:
-
Fatigue
-
Anorexia
-
Dizziness
-
Nausea
-
Vomiting
-
Headache
-
Weight loss
-
Shortness of breath
A grayish color
to the skin is a possible indication of iron toxicity.
Hemochromatosis
is a genetic disorder that affects the regulation of iron absorption. The
incidence may be as high as 5 in 1,000 in Caucasians. Treatment consists of
a low-iron diet, no iron supplements, and phlebotomy (blood removal) on a
regular basis.
Excess storage
of iron in the body is known as hemosiderosis. The increased iron stores come
from the consumption of excessive iron supplements or from receiving frequent
blood transfusions, not from increased iron intake in the diet.
If you have constant
unusual signs of tiredness, see your health care provider. There are many
causes of such symptoms, and simply taking an iron supplement may not be enough.
Those at risk
for low iron stores include:
-
Menstruating women (Women with
heavy periods are particularly at risk.
-
Pregnant and postpartum women
-- extra iron is needed to meet the needs of the growing fetus and to make
up for iron lost due to blood loss during childbirth
-
Infants are born with iron
stores that last about six months. An infant's additional iron needs are
met by breast milk. A non-breast-fed infant's iron needs can be met with
an iron supplement or iron-fortified infant formula. As babies move to solid
foods, foods containing high amounts of iron should be selected to prevent
the development of iron deficiency.
-
Toddlers between 1 and 4 years
of age are at risk for developing iron deficiency because of rapid growth
and a lack of sufficient iron in their diets unless iron-fortified foods
or a supplement is available. Because milk is a very poor source of iron,
children who drink large quantities of milk at the expense of other foods
may develop "milk anemia." Recommended milk intake is two to three cups
per day for toddlers.
-
Adolescents -- both boys and
girls -- traditionally have been prone to anemia because of rapid growth
rates, erratic eating habits, and concerns about body image.
-
Long-distance runners -- demanding
exertions may damage red blood cells
-
Strict vegetarians (animal
products contain the most bioavailable form of iron)
-
People with bleeding lesions
in their gastrointestinal tract.
-
People with absorption problems
in the gastrointestinal tract, such as celiac sprue or having had portions
of the intestines removed, which may lead to low levels of iron.

Recommendations
According to
USDA recommendations, the allowances of dietary iron intake are as follows:
-
Males and females
-
Males
-
11 to 18 years: 12 mg
-
19 and older: 10 mg
-
Females
-
11 to 50: 15 mg
-
51 and older: 10 mg
-
Pregnant: 30 mg
-
Lactating: 15 mg
Any male or postmenopausal
female with iron deficiency should be evaluated by a health care provider
to rule out whether the problem may be due to a more serious gastrointestinal
cause such as ulcers, polyps, or tumors.
The FDA's
reference daily intakes
(RDI) for Iron is 18 milligram (mg).
