second only to the
rapid growth that occurs in the first year of life.2 With the onset of puberty come increases in height, weight and bone mass; cognitive changes; and reproductive maturation.3 Adolescent boys gain more in bone size and mass than adolescent girls.3 To support this intensive and multifaceted period of growth, the total nutrient needs of adolescents are higher than at any other life
stage.
