Why Do We Need Iron?
Iron is an essential mineral that is required for our bodies to function properly. The primary reason we need iron is that it is an important component of hemoglobin, which helps transport oxygen throughout the body.
Hemoglobin represents about two-thirds of the body’s iron. If you don't have enough iron, your body can't make enough healthy oxygen-carrying red blood cells, which is called iron deficiency anemia. If you're not getting sufficient oxygen in the body, you're going to become fatigued. That exhaustion can affect everything from your brain function to your immune system's ability to fight off infections.
If you're pregnant, severe iron deficiency may increase your baby's risk of being born too early, or smaller than normal.
Iron is also necessary to maintain healthy skin, hair, and nails.

Which foods provide iron?
Probably the best known nutrition fact about iron is that meats—particularly red meats—are rich in iron. Other foods high in iron include beans, pumpkin seeds, squash seeds, raisins and dried fruit, eggs, seafood such as sardines, clams, shrimp and oysters. A number of plant foods are also rich in iron such as leafy green vegetables - spinach, legumes, cumin, and parsley.
If you think you are iron deficient or are experiencing iron overload than consult your doctor as soon as possible.
