Document Summary
Nutrition in adolescence, adulthood and the elderly notes. The total amount of nutrients needed during adolescence surpasses needs at any other time of life. Needs for many nutrients increase due to rapid growth; iron is particularly important. Increased need for calcium and zinc as well. This is because you have such rapid growth and all those hormonal changes. You need iron because of greater tissue synthesis and muscle development. Boys and girls aged 9 to 18 did not have an adequate intake of vitamin a.
