According to the Women’s and Children’s Health Network, diet has a significant effect on children’s study habits. Junk food and foods with high sugar content deplete energy levels and the ability to concentrate for extended periods of time. Energy and focus are especially crucial for school-age children. Children set the foundation for lifelong habits in their youth, making junk food particularly hazardous to their well-rounded development. Physical activity is also essential for children of all ages, and regularly eating junk food does not provide the necessary nutrients children need for sufficient energy to engage in physical activity. A lack of physical activity is harmful to physical and mental well being and may also exclude a child from critical social development.
