Answer to Question 1

A
Prostate cancer is positively associated with intake of dietary fat, especially saturated fat. The most aggressive type of prostate cancer is associated with intake of animal fat. Therefore a man is at increased risk of prostate cancer if he eats large portions of red meat several times per week. Eating eggs for breakfast most mornings, drinking two or more alcoholic beverages daily, and drinking two or more glasses of milk daily are not associated with risk of prostate cancer.

Answer to Question 2

B
Older women require less dietary iron than younger women because they do not lose iron with menstrual blood losses after menopause. Red blood cell turnover does not change with age. He-moglobin is the oxygen-carrying pigment in blood, myoglobin is the oxygen-carrying pigment in muscles, and one does not replace the other with age. Older women are not necessarily less active than younger women.
