How strong is the evidence for Mediterranean Diet?

The Mediterranean diet is among the most rigorously studied dietary patterns in nutrition science, anchored by the PREDIMED randomized controlled trial, which found reduced cardiovascular events in high-risk adults, alongside decades of large cohort studies (including the influential Greek EPIC cohort) linking adherence to lower mortality. That evidence is currently rated strong (89/100), built on 9 published studies -- enough for real confidence in the effect.
