Ikaria — Dietary patterns and exceptional longevity

In plain English

On the Greek island of Ikaria, approximately one in three residents reaches age 90, with very low rates of dementia and depression. Investigators document a Mediterranean diet rich in wild greens, beans, olive oil and herbal teas, alongside daily walking on steep terrain and strong community ties.

Caveats

Cross-sectional design captures associations, not causation. Selection effects (people who stay on the island may differ from those who leave) are hard to rule out.
