How the Mediterranean Diet Protects the Heart

The Mediterranean diet is the most extensively studied dietary pattern for cardiovascular health and has the strongest evidence base of any dietary approach for reducing cardiovascular disease risk. Named for the traditional eating patterns of populations bordering the Mediterranean Sea — southern Italy, Greece, Spain, and other countries — it has been associated in observational studies with lower rates of heart disease, stroke, cancer, diabetes, and cognitive decline for decades. Crucially, it has also been validated in randomized controlled trials — the strongest form of evidence — for reducing cardiovascular events.

WHAT IS THE MEDITERRANEAN DIET?

The Mediterranean diet is characterized more by an overall pattern than by rigid rules:

Abundant:

• Olive oil: The primary fat source — used for cooking, dressing, and flavoring
• Vegetables: A wide variety, consumed at nearly every meal
• Fruits: Fresh fruit as a typical dessert or snack
• Legumes (beans, lentils, chickpeas): Regular protein and fiber sources
• Whole grains: Bread, pasta, rice (traditionally less refined)
• Nuts and seeds: Regular snacks and meal additions
• Fish and seafood: 2+ times per week (especially fatty fish — sardines, mackerel, anchovies, salmon)
• Herbs and spices: Used liberally in place of salt
