Emergent challenges in adolescent nutrition Desafíos emergentes en la nutrición del adolescente

Abstract

Adolescence is a dynamic period of the life cycle, with significant physical, psychological and social changes, leading to autonomy and independence in eating behaviors. During this time there is an increased risk in nutritional behavior, including excessive intake of calories, increased consumption of fat, cholesterol, and simple carbohydrates, and nutrient deficiencies such as calcium. In addition other behaviors are at risk, including disorganized mealtimes, eating outside the home, and the onset of eating behavior disorders and addictions (caffeine, alcohol). It is necessary to develop preventive educational programs including physical activity among adolescents, to promote healthy behaviors into adulthood. Significant literature in Chile and South America is reviewed.
