Canadian Study Suggests That Middle-Aged Men Need More Protein To Maintain Muscle Mass

February 4, 2013: 12:00 AM EST
A study by Canadian researchers finds that middle-aged men need more than current recommended daily amounts of protein in their diets to maintain muscle mass that is lost with aging. The study measured muscle protein synthesis in 35 men who exercised but did not lift weights. Researchers found that eating a six-ounce serving of 85 percent lean ground beef significantly improved the rate of muscle protein synthesis following exercise. Canada’s Food Guide currently recommends eating about three ounces of meat per serving to provide adequate protein to maintain muscle mass.
