For example, carbohydrates are the primary source of energy for the body, proteins are essential for building and repairing tissues, and fats play a vital role in providing energy, supporting cell growth, and aiding in the absorption of certain vitamins.

Micronutrients, which consist of vitamins and minerals, are also critical for the body. They play roles in biochemical reactions, support the immune system, and are required for growth and development. For instance, vitamins help regulate various processes in the body, including metabolism, and minerals are required for bone health and fluid balance.
