Which of the following promotes increased iron absorption?
a. Repeated phlebotomy
b. Eating iron-rich foods along with those high in ascorbic acid
c. Desferrioxamine
d. Vegetarian diet
ANS: B
Ascorbic acid enhances iron absorption. Iron in vegetables is nonheme iron, and it is not readily absorbed. Desferrioxamine chelates iron and is used therapeutically for patients with transfusion-dependent hemochromatosis. Repeated phlebotomy depletes iron, and it is the treatment used for patients with the hereditary form of hemochromatosis.
