What are proteins considered in relation to macronutrients?

Proteins are considered one of the three main macronutrients alongside carbohydrates and fats. They play a crucial role in the body, serving as building blocks for tissues, enzymes, hormones, and various bodily functions. Proteins are made up of amino acids, which are essential for growth, repair, and maintenance of body cells.

This classification as a macronutrient is significant because, like carbohydrates and fats, proteins provide energy (calories) and are essential for various physiological functions. Recognizing proteins as one of the main macronutrients emphasizes their importance in a balanced diet, where all three macronutrients are needed to support overall health and well-being.
