The Takeaway
- The Mediterranean diet improves heart health, brain health, and longevity.
- It emphasizes plants, whole grains, olive oil, nuts, beans, and seafood.
- Research consistently links it to lower risk of heart disease and dementia.

A Diet That Sticks
You’ve probably heard about the Mediterranean diet for years. But new insights from nutrition researchers at Harvard Chan School help explain why it’s so effective.
This way of eating — common in places like Greece and southern Italy — keeps inflammation down, stabilizes blood sugar, and nourishes the gut microbiome. And unlike fad diets, it’s pleasant and sustainable.
What Makes It Work
- Healthy fats from olive oil and nuts
- High fiber from vegetables, beans, and whole grains
