Overview
- The COINS randomized controlled trial enrolled 120 community-dwelling adults aged 66–89 who were at risk for falls.
- Participants assigned 43 g of natural peanut butter daily for six months completed five sit-to-stand tests faster than controls, indicating greater lower-body muscle power.
- The intervention increased protein and unsaturated fat intake, providing about 10 g of protein per day without weight gain.
- Researchers describe the food-based strategy as a practical complement to strength and resistance training and a familiar alternative to commercial oral nutrition supplements.
- The peer-reviewed results appeared in the Journal of Cachexia, Sarcopenia and Muscle; funding came from The Peanut Institute Foundation with no reported role in the research.
