Summary

This study looked at whether a diet rich in a special olive oil (high in phenolic compounds) plus prebiotic supplements could help people aged 60-80 who have sarcopenia (age-related muscle loss). The goal was to see if this approach could improve muscle mass, strength, and walking speed, and also reduce heart disease risk. 39 participants followed the diet for 12 weeks, with a 12-week follow-up to see if any benefits lasted.
