Our bodies need nutrients from food to grow and stay healthy. Food provides proteins, fats, vitamins, minerals, carbohydrates and water. Carbohydrates provide energy but should come from fruits, vegetables and whole grains rather than sweets and processed foods. Proteins help build the body but should be consumed in moderation. Fats are important but saturated fats should be limited. Vitamins and minerals from foods keep us strong and prevent illness; deficiencies can cause various health issues. Staying hydrated with water is also essential for health.
