What contributes to a child's health according to childhood needs?

A nutritious diet is essential for a child's health as it provides the necessary vitamins, minerals, and energy required for growth and development. Proper nutrition supports not only physical health but also cognitive functioning, thereby enhancing learning and emotional well-being. A balanced diet rich in fruits, vegetables, whole grains, protein, and healthy fats contributes to a stronger immune system, better concentration, and overall improved physical health, which aligns with the fundamental needs of children for optimal development.

On the other hand, the other options highlight factors that are typically detrimental to a child's health. Increased screen time can lead to sedentary behavior and associated health issues, high-stress activities may create anxiety and impact mental health negatively, and minimal physical activity can result in obesity and a host of physical health problems. Each of these factors contrasts with the necessity of a nutritious diet in supporting holistic child health.
