1. Energy Supply
Food provides the body with the energy needed for daily activities and bodily functions, mainly from carbohydrates (sugars, starches), fats, and proteins. This energy fuels physical activity, supports metabolic processes, and helps maintain body temperature.
2. Growth and Development
Food supplies the nutrients needed for growth, development, and tissue repair — mainly proteins, along with vitamins (especially Vitamin D and calcium) and minerals. This is essential for children’s growth, muscle repair, and overall development throughout life.
3. Regulation of Body Processes
Food helps regulate bodily functions, including enzyme and hormone production, immune response, and fluid balance — supplied by vitamins (A, C, D, E, K, B-complex), minerals (iron, zinc, magnesium), and water. This maintains homeostasis, supports the immune system, and ensures the body’s systems function properly.
