The X and Y Chromosomes Determine Your Sex. One chromosome pair - the sex chromosomes - is unique. You don't necessarily end up with a matching pair. Typically females have two X chromosomes and males have an X and a Y. Mothers always pass an X chromosome on to their children.
On the other hand, the absorption of nonheme iron, the major dietary pool, is greatly influenced by meal composition. Ascorbic acid is a powerful enhancer of nonheme iron absorption and can reverse the inhibiting effect of such substances as tea and calcium/phosphate.
Vitamin C also helps overcome the adverse effects of the phytonutrients that inhibit nonheme iron absorption, including oxalic acid, phytic acid, tannins and polyphenols. Bell peppers, broccoli, red cabbage, tomatoes, sweet potatoes, cantaloupe, oranges, mangos and strawberries are excellent sources of vitamin C.
