It provides nutrients that the body uses for growth and health. There are five types of nutrients that fall into two broad categories: macronutrients and micronutrients. Macronutrients, which are required in large amounts, include carbohydrates, proteins and fats. In contrast, micronutrients are required in small amounts and include vitamins and minerals.
