Which nutrient helps in the repair and growth of tissues?

Proteins are essential for the repair and growth of tissues due to their role as building blocks in the body. They are made up of amino acids, which are crucial for several bodily functions, including the development of muscles, skin, organs, and other tissues. When the body undergoes repair processes, such as after an injury or during growth periods, proteins are necessary to synthesize new cells and to regenerate damaged ones.

While fats, carbohydrates, and vitamins all play vital roles in overall health, they do not primarily provide the structural components that proteins do. Fats are important for energy storage and cell membrane integrity, carbohydrates serve as the body’s main energy source, and vitamins are essential for various biochemical processes but do not directly contribute to tissue formation or repair in the way that proteins do. Thus, proteins are recognized as the key nutrient for tissue repair and growth.
