In a new brief, Early Childhood Policy Focus: Healthy Eating and Physical Activity, Child Trends reviews recent data and current research on nutrition and exercise habits of young children under the age of six. A number of factors affect these habits, including personal choices by parents and children, financial constraints (such as the availability, accessibility, and cost of healthy options), and public policies. Research on these factors offers insights into ways to encourage the development of healthy eating and physical fitness habits in early childhood and beyond.
