What is the main role of protein in the body?

Explanation:
Protein’s main job is to build and repair body tissues, especially muscles. After training, muscles experience small-scale damage, and amino acids from protein are used to repair and rebuild those fibers, helping them grow stronger over time. While protein can be used for energy if needed, its primary function is not energy production—that role belongs to carbohydrates and fats. Hydration is managed by fluids and electrolytes, and storing vitamins is not a primary task of protein. So, focusing on muscle growth and repair best captures its main role.
