Why would a diet deficient in iron lead to anemia?

Iron deficiency is the most common cause of anemia worldwide. Iron is an essential mineral that the body needs to produce hemoglobin, a protein in red blood cells that carries oxygen from the lungs to the rest of the body. Without enough iron, the body cannot produce enough hemoglobin, which leads to anemia.

People who are most at risk for iron deficiency anemia include:

* Women who are pregnant or menstruating

* Children

* Adolescents

* Athletes

* Vegetarians and vegans

* People with certain medical conditions, such as celiac disease, Crohn's disease, and ulcerative colitis

Symptoms of iron deficiency anemia can include:

* Fatigue

* Weakness

* Pale skin

* Brittle nails

* Hair loss

* Shortness of breath

* Chest pain

* Dizziness

* Headache

If you think you may be iron deficient, it is important to see your doctor to get a blood test to check your iron levels. If you are diagnosed with iron deficiency anemia, your doctor will recommend treatment, which may include taking iron supplements.

Some foods that are high in iron include:

* Red meat

* Poultry

* Fish

* Beans

* Lentils

* Spinach

* Kale

* Collard greens

* Broccoli

* Raisins

* Prunes

* Apricots

* Peaches

* Oranges

* Grapefruit

If you are unable to get enough iron from your diet, you may need to take iron supplements. However, it is important to talk to your doctor before taking iron supplements, as too much iron can be harmful.
