Question

1 — adult (20-39)
learning objective: determine the nutritional needs of young adults.
which nutrient do adult males need more of than adult females?
a.) iron
b.) vitamin a
c.) vitamin d
d.) selenium

Explanation:

• Iron: Adult females (especially of reproductive age) need more iron due to menstrual blood loss, so males don't need more iron than females.
• Vitamin A: The recommended dietary allowance (RDA) for vitamin A is similar for adult males and females in the 20 - 39 age group, or females may have slightly different but not males needing more.
• Vitamin D: The RDA for vitamin D is the same for adult males and females in this age range (e.g., 10 - 20 mcg/day depending on factors, but no gender - based difference in requirement magnitude here).
• Selenium: The RDA for selenium is 55 mcg/day for adult females and 70 mcg/day for adult males, so adult males need more selenium than adult females.

Answer:

d.) Selenium
