Older adults gain muscle power with daily servings of everyday snack, study finds

A daily helping of one food in particular may help boost muscle power in older adults, according to a new study.

Adults 65 and older who consumed about three tablespoons of peanut butter for six months improved their performance on a key lower-body function test compared to a control group, researchers at Deakin University in Australia found.

The study, published last month in the Journal of Cachexia, Sarcopenia and Muscle, followed 120 older adults who were living alone and at risk of falls.
