What is the function of iron in the human body?

What is iron in food?

Iron is a mineral that is naturally present in many foods, added to some food products, and available as a dietary supplement. Iron is an essential component of hemoglobin, an erythrocyte (red blood cell) protein that transfers oxygen from the lungs to the tissues [ 1 ]. As a component of myoglobin, another protein that provides oxygen, iron supports muscle metabolism and healthy connective tissue [ 2 ]. Iron is also necessary for physical growth, neurological development, cellular functioning, and synthesis of some hormones [ 2, 3 ].

Where is iron stored in the body?

Much of the remaining iron is stored in the form of ferritin or hemosiderin (a degradation product of ferritin) in the liver, spleen, and bone marrow or is located in myoglobin in muscle tissue [ 1, 5 ]. Transferrin is the main protein in blood that binds to iron and transports it throughout the body.

What is the richest source of iron?

Food. The richest sources of heme iron in the diet include lean meat and seafood [ 19 ]. Dietary sources of nonheme iron include nuts, beans, vegetables, and fortified grain products. In the United States, about half of dietary iron comes from bread, cereal, and other grain products [ 2, 3, 5 ].

What are the two main forms of iron?

Dietary iron has two main forms: heme and nonheme [1]. Plants and iron-fortified foods contain nonheme iron only, whereas meat, seafood, and poultry contain both heme and nonheme iron [2]. Heme iron, which is formed when iron combines with protoporphyrin IX, contributes about 10% to 15% of total iron intakes in western populations [3-5].

Why are infants at risk for iron deficiency?

Infants—especially those born preterm or with low birthweight or whose mothers have iron deficiency—are at risk of iron deficiency because of their high iron requirements due to their rapid growth [ 34, 45 ]. Full-term infants usually have sufficient iron stores and need little if any iron from external sources until they are 4 to 6 months old [ 2 ]. However, full-term infants have a risk of becoming iron deficient at 6 to 9 months unless they obtain adequate amounts of solid foods that are rich in bioavailable iron or iron-fortified formula.

What is the term for a depleted iron store?

Iron deficiency progresses from depletion of iron stores (mild iron deficiency), to iron-deficiency erythropoiesis (erythrocyte production), and finally to iron deficiency anemia (IDA) [8,9]. With iron-deficiency erythropoiesis (also known as marginal iron deficiency), iron stores are depleted and transferrin saturation declines, but hemoglobin levels are usually within the normal range. IDA is characterized by low hemoglobin concentrations, and decreases in hematocrit (the proportion of red blood cells in blood by volume) and mean corpuscular volume (a measure of erythrocyte size) [2,10].

Why is iron deficiency a risk factor for gastrointestinal disorders?

People with certain gastrointestinal disorders (such as celiac disease, ulcerative colitis, and Crohn’s disease) or who have undergone certain gastrointestinal surgical procedures (such as gastrectomy or intestinal resection) have an increased risk of iron deficiency because their disorder or surgery requires dietary restrictions or results in iron malabsorption or blood loss in the gastrointestinal tract [ 55-57 ]. The combination of low iron intake and high iron loss can lead to a negative iron balance; reduced production of hemoglobin; or microcytic, hypochromic anemia [ 58 ].

What does iron do to the body?

What is iron and what does it do? Iron is a mineral that the body needs for growth and development.

What happens if I don’t get enough iron?

In the short term, getting too little iron does not cause obvious symptoms. The body uses its stored iron in the muscles, liver, spleen, and bone marrow. But when levels of iron stored in the body become low, iron deficiency anemia sets in. Red blood cells become smaller and contain less hemoglobin. As a result, blood carries less oxygen from the lungs throughout the body.
