Answer:During childhood and adolescence, good nutrition and dietary behaviors are important to achieve full growth potential and appropriate body composition, to promote health and well-being, and to reduce the risk of
chronic diseases in adulthood. Children require sufficient energy, protein, and other nutrients for growth as well as maintenance of body functions. Nutrient needs tend to parallel rates of growth. Growth continues at a steady rate during childhood, then accelerates during adolescence, creating increases in nutrient needs to support the rapid growth rate and increase in lean body mass and body size (Story et al., 2002a). During puberty, adolescents achieve the final 15 to 20 percent of stature, gain 50 percent of adult body weight, and accumulate up to 40 percent of skeletal mass (Story et al., 2002a). Inadequate intakes of energy, protein, or certain micronutrients will be reflected in slow growth rates, delayed sexual maturation, inadequate bone mass, and low body reserves of micronutrients (Story et al., 2002a).
