Protein is necessary for the building of muscle mass, repairing tissues in the body and the creation of hemoglobin.  Muscle mass helps support a healthy weight through increased metabolism and assists in the repairing of damaged muscle tissue from exercise and aging tissue.  Hemoglobin is necessary for the transportation of oxygen in the body to muscles and organs.  Protein also plays an important part of immune response.  Eating an inadequate amount of protein can have an impact on the body’s ability to fight off infection and disease.  Protein is also necessary for the repair of bones.
