What is the primary purpose of protein in our diet?

The primary purpose of protein in our diet revolves around tissue growth and repair. Proteins are made up of amino acids, which are the building blocks necessary for the formation and maintenance of body tissues, including muscles, organs, and skin. When the body is injured or needs to grow (such as during childhood or after surgery), proteins play a crucial role in rebuilding and repairing cells.

While proteins can contribute to energy production and support enzymatic functions, their main function is closely associated with growth and repair of tissues rather than serving as a primary energy source. Hydration is not a role of protein; instead, it relates to water and the balance of fluids in the body. Therefore, recognizing tissue growth and repair as the primary purpose of protein provides clarity on its essential function in maintaining overall health and bodily integrity.
