Protein Supplements for the Elderly
Physical performance deteriorates as people age, but protein supplements may combat such decline, a study found. Researchers enlisted 65 frail older people to consume either a beverage containing 15 grams of protein twice daily or a placebo drink without protein. By the end of the study, protein-packed participants had faster walking speeds, better balance, and a greater capacity to rise from a chair unassisted than those who’d consumed the zero-protein beverages. The scientists observed that muscle mass didn’t increase with the extra protein; they suspect that the protein supplements may improve muscle quality, not size.
