What are macronutrients?

Macronutrients are substances that provide the energy necessary for the body's growth, metabolism, and overall functioning. They include carbohydrates, proteins, and fats—nutrients that the body needs in large amounts to maintain proper health and energy levels.

Unlike micronutrients, which are required in small amounts and include vitamins and minerals, macronutrients play a crucial role in providing energy (calories) and are essential for the development and maintenance of bodily functions. For instance, carbohydrates are the body's primary energy source, proteins are vital for building and repairing tissues, and fats provide energy as well as help absorb certain vitamins.

The classification as "nutrients required in large amounts" distinguishes macronutrients from other types of nutrients. This distinction is important in understanding dietary needs and nutrition planning, highlighting the significance of balance among the different macronutrients for optimal health.
