Macronutrients – carbohydrates, proteins, and fats – are the primary sources of energy. Carbohydrates should make up about 50-60% of a child's total energy intake, proteins around 10-15%, and fats approximately 25-35%. Each macronutrient has a specific role: carbohydrates are the main energy source, proteins are vital for growth and repair, and fats are essential for brain development and hormone production.
