The only nutrients that can build and repair body tissues are:

Proteins are considered the primary nutrients responsible for building and repairing body tissues. This is because proteins are composed of amino acids, which serve as the building blocks for various tissues in the body, including muscle, skin, and organs. When the body is in a state of growth, healing, or maintaining muscle mass, proteins play a crucial role in synthesizing new tissues and repairing damaged ones.

While fats, carbohydrates, and minerals are essential for overall health and bodily functions, they do not have the same direct role in tissue building and repair as proteins do. Fats serve primarily as energy sources and are crucial for cellular structure and hormone production, while carbohydrates are also mainly energy providers. Minerals support various biochemical functions and help maintain structural integrity in bones and teeth but do not directly facilitate tissue repair in the way proteins do. This distinction emphasizes the unique role proteins play in growth and recovery processes within the body.
