The global rise of obesity in children has raised serious concern for their current and future health and well-being. The prevention and treatment of childhood and adolescent obesity must encompass all aspects of a child's life, including home, school, and other settings. A multidisciplinary approach is critical, including physical activity, behavioral factors, and proper dietary habits. Age-appropriate nutrition education and role modeling from adults in children's lives can be important in promoting lifelong healthy eating. Foods to emphasize include vegetables, fruits, whole grains, legumes, low-fat dairy products, and lean sources of protein. Foods and beverages with low nutrient density and high energy density should be consumed in moderation, within a child's discretionary calorie allowance. The overall diet must support proper growth, health, development, academic achievement, and well-being without supplying excess energy beyond needs.
