Protein is an essential nutrient made up of building-block chemicals called amino acids. Protein provides energy and is needed for the body to make new cells, to maintain and rebuild muscles, to carry other nutrients, to act as messengers in the body, and to support the immune system.
You can get protein from meat, eggs, fish, poultry, dairy, legumes, soy, nuts, and grains.
