Which of the following groups is least likely to develop iron deficiency?
a. Infants
b. Young men
c. Teenage girls
d. Adult premenopausal women
ANS: B
Young men can easily absorb enough iron to replace the small amount they lose each day and, in fact, can absorb slightly more than needed so that their stores remain adequate. Infants, as they grow, have an expanding erythron requiring more iron. Teenage girls and adult premenopausal women lose iron during their menstrual cycle, and may not absorb adequate amounts of iron to replace all that is lost.
