Mediterranean Diet Linked to Lower Death Risk Across 1.8 Million People

Strong Evidence·Nutrition (Burbank, Los Angeles County, Calif.)·Mar 2026

Pooling 54 studies with over 1.8 million participants, each one-point bump on a Mediterranean diet score was linked to a 4% lower risk of dying from any cause. The studies covered diverse populations worldwide, with follow-up periods ranging from 2 to 60 years. Evidence certainty was rated moderate, meaning the association is fairly reliable but not ironclad.

Key Insight

This research suggests closer adherence to Mediterranean-style eating may be associated with longer life.
