Answer to Question 1

A

Answer to Question 2

People lose about 1.0 mg of iron per day. Additionally, women of childbearing age would lose about 0.5 mg of iron per day over the course of a month. In total, women of childbearing age should replace 1.5 mg of iron per day to avoid a deficit. Because only about 18 percent of iron consumed is absorbed, we would take 1.5 0.18 to determine that a total of 8 mg of iron must be consumed daily to prevent a net dietary loss of iron. For a vegetarian woman of childbearing age, however, the dietary intake is 1.8 times higher for vegetarians, so take 8 mg 1.8 to determine that these women will need a total of 14 mg of iron daily to avoid a net dietary loss of iron.
