Document Summary
Very important component of hemoglobin (contains some units of iron atoms bound to a heme group) Heme- in meat, poultry, fish and seafood. It"s in a heme molecule from hemoglobin or myoglobin. Non-heme iron- in beans, lentils, grains and some vegetables, iron added to flour or breakfast cereals. Cooking in cast iron increases the iron content of your food (2-10 mg increase) This is why vegetarians may have trouble getting enough iron. Do the dris take absorption into account- yes. 70% of our body"s iron is in hemoglobin. Hemoglobin in red blood cells transports oxygen to body cells and carried carbon dioxide from cells for elimination by the lungs. Found in enzymes that are needed to metabolize energy from cho, fat and protein. Cyanide is a poison, found in apple and peach seeds. How does it work?- binds to the iron in cytochromes and stops cells from using oxygen which causes death.
