NFS284H1 Lecture Notes - Lecture 11: Superoxide Dismutase, Zinc Deficiency, Enterocyte
Document Summary
Iron may be a nutrient of concern for women of reproductive age. Zinc intake may also be of concern for older adults (50+) 2 forms of iron in the diet: heme iron, mostly from myoglobin in food from animal sources (ex. Muscle meats: non-heme iron, found in plant sources, not as well absorbed as heme iron. One way to increase iron consumption without increasing calories is to use iron cookware with acidic foods: promotes the leeching of iron into the food. Iron is an important nutrient: absorption well studied. Non-heme iron (ferric form) is converted to ferrous form (more absorbable) in the stomach. Iron supplements contain ascorbic acid because it stabilized the ferrous form. Animal proteins, from meat, fish or poultry, enhance absorption of iron. If you add ground beef to chili, you will enhance the absorption of the iron from beans.
