Iron is an essential trace mineral that is vital for specific functions in the body. It is responsible for carrying oxygen from the lungs to the rest of the body. About 70 percent of the iron in your body is stored in the red blood cells. Iron is an essential nutrient -- meaning, the body is unable to make it. Therefore, it must be obtained from the foods we eat. Iron deficiency is one of the most common types of nutrient deficiencies. People who are deficient in iron are at risk of developing a condition called anemia in which there are not enough healthy red blood cells in the body. Symptoms of anemia include fatigue, weakness, dizziness, lightheadedness, pale skin, and sleep disturbances. The following ten foods are rich in iron, so add them to your diet to ensure that you are meeting your recommended daily intake every day.

Clams are also an excellent source of vitamin A, vitamin C, B vitamins, phosphorus, potassium, zinc, copper, manganese, and selenium.

Beef

Beef is an excellent source of heme iron, and an outstanding food to eat if you are prone to anemia. Heme iron is the type of iron found in blood and muscle — in other words; it's only available in animal foods. Heme iron is absorbed more quickly by the body than nonheme iron. This is good because it prevents anemia; however, too much heme iron can increase oxidative stress. This is why meat should be eaten in moderation. A 3-oz serving of meat — depending on the cut and the fat content — contains 2.4-2.7 mg of iron or around 15% of your RDI.

Oats are also an excellent source of dietary fiber and protein, so a bowl of this stuff in the morning will keep you full and satisfied for many hours after eating. Oats are also rich in essential minerals magnesium, phosphorus, potassium, zinc, copper, manganese, and selenium.
