Physical activity and nutritious eating promote good health and reduce the risk of chronic disease. Regular exercise can help control weight; reduce the risk of heart disease, type 2 diabetes and some cancers; strengthen bones and muscles; and improve mental health. Proper nutrition also lowers people’s risk for heart disease, stroke and some types of cancer, diabetes and osteoporosis. By reducing chronic diseases, regular physical activity and healthy eating may also lower health care costs. Policymakers are striving to provide opportunities for physical activity and nutritious food choices in schools, workplaces and communities.
