Disease Prevention and Risk Reduction
In a 2009 study, published in the Journal of the American Dietetic Association, researchers at the Graduate Center for Gerontology at the University of Kentucky, Lexington, determined that a daily 4oz serving of lean beef increased muscle protein synthesis by about 50%. Researchers noted that ingestion of high-quality protein is of paramount importance in the maintenance of muscle mass and function in elderly people. This is especially important in protecting the elderly and the physically inactive from sarcopenia. Sarcopenia, the loss of muscle mass, strength, and function, begins after 40 and accelerates after the age of 75.
