## Summary

Older adults who ate closest to the Planetary Health Diet, a mostly plant-based pattern, had roughly half the odds of being frail. The study tracked over 6,500 older people in Spain, checking frailty several times across two groups. Vegetables and fruits showed the strongest links, and the diet was mainly tied to staying more physically active. Diet was measured only once at the start, so this shows a link, not proof the diet prevents frailty.

## Practical Takeaway

This study suggests a diet rich in vegetables and fruit may be linked to less frailty.
