Story summary

A Deakin University study in Australia found that three tablespoons of peanut butter daily for six months improved muscle power in adults aged 65 and older.
Participants showed a 1.2-second improvement in a five-times sit-to-stand test, indicating better lower-body function.
There were no changes in walking speed or overall strength.
The results are modest and do not guarantee reduced fall rates.
Further studies are needed for frailer seniors.
