Adolescents gain independence by taking a greater role in food choices and amounts eaten. It is frustrating for parents who worked to establish standards to see the young person seek independence, even with foods consumed. This is a stage in life that demands high caloric intake, because growth needs are second only to those in infancy—more kilocalories per kilogram are needed than in any other life stage. This high caloric consumption is favorable to nutritional status because with high calories comes the increased likelihood of taking in more nutrients. Parents must remain hopeful that good health habits will guide the teenager. There may be concern over peer pressure leading to "strange" or different food habits, such as disordered eating, sports nutrition, and vegetarian diets, which many teens attempt. Such exploration is often a natural part of expressing independence. These food patterns can be healthy, such as improving food habits with vegetarianism or sports nutrition. The family physician needs to determine when the teen's exploration could become harmful. Nutrition assessment is appropriate in this life stage in regard to determining whether a nutritional problem is present.
