Macronutrients differ from micronutrients in the diet in terms of their roles and required quantities. Macronutrients—carbohydrates, proteins, and fats—are needed in larger amounts as they provide the energy necessary for daily activities and bodily functions. Carbohydrates serve as the body’s primary energy source, while proteins are vital for muscle repair and growth, and fats support cellular function. Conversely, micronutrients—vitamins and minerals—are required in smaller amounts but are essential for numerous physiological processes, including immune function and bone health. Both categories are crucial for a balanced diet.
