Macronutrients

Topic

Macronutrients are nutrients that organisms require in relatively large amounts to provide energy, support growth, and maintain metabolic systems. In human nutrition, the primary macronutrients are carbohydrates, proteins, and fats, which are essential for sustaining life and bodily functions. Other substances, such as water and dietary fiber, are also sometimes classified as macronutrients due to the large quantities required by the body.
