Optimal nutrition is critical for children’s short- and long-term health including maintaining a healthy weight and prevention of chronic diseases, as well as physical development, cognitive development, early learning, and academic success. Many communities across America are changing public policy, community environments, and industry practices to better support healthy eating, physical activity, and healthier choices for kids and families so that all children have a healthy start in life and are able to grow up at a healthy weight. Research in this area focuses on monitoring and improving eating patterns and overweight and obesity trends, and understanding how policies, systems, and environments impact food and beverage choices and weight status.
