Meat as a class is a good iron food, especially red meat. Red meat gets its red color from the large amount of iron. People who eat red meat do not usually suffer from iron deficiency. If you do eat red meat and have low iron, ask your health care provider about your situation because you may have complicating factors, from your absorption of iron to high levels of blood loss.
All types of meat have the extra advantage of assisting your body to metabolize more iron from fruits, vegetables, grains, and beans. Plant sources of iron are often bound in iron inhibitors, making plant-based iron tougher to assimilate. A small amount of meat will help your body to absorb the iron and carry it into your red blood cells where your body can use it. Learn more about meat as an iron enhancer here.
