Document Summary
A trace mineral (opposite of major mineral) Heme iron: in meat, poultry, fish and seafood. Non-heme iron: beans, lentils, grains and veggies. Things that help absorption of non-heme: vitamin c, meat. Things that inhibit absorption: calcium, phytates, tannins, soy bean protein. Cooking in cast iron pots or pans (some iron leeches out of pan into the food) Vegan diet: 10% (this is why vegans have trouble getting enough iron) 2/3 of our body"s iron is in hemoglobin. Your body can"t make hemoglobin without iron. A component of myoglobin (transports oxygen in muscles) Found in enzymes that are needed to metabolize energy from cho, fat and protein (cytochromes in the electron transport chain) Binds to the iron in cytochromes and stops energy metabolism. Pregnant women need more because making the cells of a baby requires iron, making more blood cells requires iron. Too little iron has major effects on the health of your blood.
