Mediterranean Diet — Diets

Plant-forward dietary pattern rich in olive oil, fish, vegetables, and whole grains with the strongest evidence base for cardiovascular and all-cause mortality reduction.

Overview

The Mediterranean diet is a plant-forward eating pattern characterized by high intake of extra virgin olive oil, vegetables, fruits, legumes, nuts, whole grains, and fish, with moderate red wine consumption and limited red meat and processed foods. It has the most robust evidence base of any dietary pattern, anchored by the landmark PREDIMED trial (7,447 participants) which demonstrated a 30% reduction in major cardiovascular events. Subsequent meta-analyses encompassing >12 million person-years consistently show reductions in all-cause mortality, cardiovascular disease, type 2 diabetes, cognitive decline, and certain cancers. The diet's benefits are attributed to its anti-inflammatory, antioxidant, and gut microbiome-modulating properties.

Indications

  • Cardiovascular disease prevention
  • Type 2 diabetes risk reduction
  • Cognitive decline and dementia prevention
  • All-cause mortality reduction
  • Anti-inflammatory nutrition

Mechanism of Action

EVOO oleocanthal and hydroxytyrosol provide potent anti-inflammatory effects comparable to ibuprofen at dietary doses
