A new study from Australia indicates that a simple dietary addition—peanut butter—may help older adults maintain muscle power and reduce the risk of falls. Researchers found that consuming about 1.5 servings (43 grams) of peanut butter daily for six months led to measurable improvements in lower-body power compared to a control group.
The six-month trial involved 108 adults aged 65 and older. Participants who ate peanut butter daily showed better performance in sit-to-stand tests, which assess lower-body strength crucial for activities like rising from a chair. The intervention was well-adhered to, with an 86% compliance rate, suggesting it's a feasible habit.
Peanut butter provides plant-based protein, healthy fats, and calories, nutrients important for maintaining muscle. The study also noted an improvement in overall diet quality for the peanut butter group without associated weight gain.
Experts caution that peanut butter is not a standalone solution. Maintaining strength and mobility with age still requires a balanced diet and regular strength-building exercise. However, this research highlights a simple, accessible food that could play a supportive role in healthy aging.
