Iron is an essential mineral that's present in all cells. As a key component of hemoglobin in the blood, for example, it helps carry oxygen from the lungs to the rest of the body.
People who don't have enough iron in the blood may have fewer-than-normal red blood cells, a condition called iron deficiency anemia.
The U.S. Centers for Disease Control and Prevention offers these risk factors for iron deficiency:
- Being a baby or toddler, or a pregnant woman.
- Having lost a significant amount of blood.
- Eating a diet that lacks enough meat, poultry or fish that are rich in iron.
- Being vegetarian.
- Taking certain medications to manage ulcers or acid reflux.
Health Tip: Help Prevent Anemia
Anemia occurs when a person has too few red blood cells or insufficient amounts of a vital blood protein called hemoglobin. This means your blood may not be carrying enough oxygen to all parts of your body.
Some types of anemia are preventable, the National Women's Health Information Center says. It offers these suggestions:
- Eat plenty of iron-rich foods, such as tofu, green and leafy vegetables, lean red meat, lentils, beans and iron-fortified cereals and breads.
- Eat and drink vitamin C-rich foods and drinks.
- Avoid drinking tea or coffee with your meals, as they can affect iron absorption.
- Get enough vitamin B12 and folic acid in your diet.
