Children require a balanced intake of essential nutrients to support their rapid growth and development. Some of the most important nutrients include proteins, carbohydrates, fats, vitamins, and minerals. Proteins are crucial for tissue growth and repair, carbohydrates provide the main source of energy, and fats are necessary for brain development and hormone production. Vitamins and minerals like calcium, iron, and vitamin D are vital for bone health, blood production, and overall immune function.
