A new study indicates that consuming about three tablespoons of peanut butter daily for six months can improve muscle power in older adults, specifically in lower-body function. Participants in the study showed faster performance on a sit-to-stand test, a key indicator of functional independence, compared to a control group.
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.

'In this trial, we measured different aspects or dimensions of physical function, such as mobility, balance, muscle power and muscle endurance,' lead researcher Dr. Sze-Yen Tan, associate professor of nutrition at Deakin University’s Institute for Physical Activity and Nutrition, told Fox News Digital. 'Peanut butter intervention had a positive effect on muscle power, which is important for activities such as getting out of a chair and climbing the stairs — but it did not help older people walk faster,' Tan said. The five-times sit-to-stand test is an indicator of lower-body muscle power and functional independence, according to the researchers.

Muscle power — the ability to generate force quickly — is especially important for preventing falls, experts say. 'Many real-world tasks that prevent falls, such as catching oneself during a trip or rising quickly from a chair, depend heavily on rapid force production,' said Dr. Sam Setareh, a cardiologist at Cedars-Sinai Medical Center; he was not involved in the research.

Despite the encouraging results, Setareh cautioned that the improvement is modest. 'A change of this magnitude is small, but potentially relevant,' he said. 'From a clinical standpoint, it is encouraging but not practice-changing.' The study did not measure actual fall rates, fractures or hospitalizations, and found no improvements in overall strength.

Tan emphasized that peanut butter should not be viewed as a cure-all. 'Eating 43 grams per day over six months was found to be effective in increasing protein intake and better muscle power,' she said. 'It can be part of the habitual diets of older adults.' TEST YOURSELF WITH OUR LATEST LIFESTYLE QUIZ Peanut butter is an affordable and familiar option for most older adults, she noted, and can be easy to eat for those with dental issues. However, pairing protein intake with resistance and balance training is critical, Setareh added. 'The optimal strategy for fall prevention combines adequate protein intake with progressive resistance and balance training,' he said.
