What Is the Mediterranean Diet? A Flexible, Plant-Forward Eating Pattern

The Mediterranean diet is an eating pattern based on the traditional cuisines of countries like Greece and Italy. It emphasizes plant-based foods, healthy fats like olive oil, and fish, while limiting red meat and processed foods.

What Mediterranean Diet means

The Mediterranean diet is less of a strict diet and more of a flexible eating pattern. It’s based on the traditional foods and drinks of countries that border the Mediterranean Sea. The core of the diet is a high intake of plant-based foods: vegetables, fruits, whole grains, legumes, nuts, and seeds. Olive oil is the principal source of added fat. The pattern also includes moderate amounts of fish and poultry, and low amounts of dairy products, red meat, processed meats, and sweets.

The concept comes from observations of the long, healthy lives of people in areas like Crete, Greece, and southern Italy in the mid-20th century. Their traditional diets were rich in plant foods and unsaturated fats. It’s important to distinguish this from some modern American versions of Italian or Greek food, which can be heavy in refined pasta, red meat, and cheese. The traditional pattern is more rustic and centered on whole, minimally processed ingredients.

Because it’s a pattern rather than a rigid set of rules, the Mediterranean diet can be adapted to different preferences and lifestyles. It doesn’t require counting calories or macros. Instead, it encourages a shift in the balance of foods you eat. The approach also often incorporates lifestyle elements associated with the region, such as regular physical activity and the social aspect of sharing meals with others, which can contribute to overall well-being.

While it is a widely recommended eating pattern, it has some considerations. The term ‘Mediterranean’ covers a large and diverse region with many different cuisines, so there isn’t one single version of the diet. Access to and the cost of fresh produce and fish can be a challenge for some. Also, its lack of specific portion sizes or meal plans might be difficult for individuals who prefer a more structured approach to eating for health or weight management goals.

How to Eat a Mediterranean-Style Diet

1. Make vegetables, fruits, whole grains, and legumes the foundation of your meals.
2. Use olive oil as your main source of added fat instead of butter or other fats.
3. Eat fish, especially fatty fish like salmon or sardines, at least twice a week.
4. Limit red meat to a few times a month, and enjoy poultry, eggs, and dairy in moderation.
5. Choose nuts, seeds, or fruit for snacks instead of processed foods with added sugar.
6. Flavor foods with herbs and spices instead of relying heavily on salt.

Common misconceptions

• Myth: It’s all about pasta, bread, and cheese. While whole grains are included, the diet emphasizes a wide variety of foods, with vegetables, fruits, and legumes making up the largest portion of meals. Refined carbs are not a central feature.
• Myth: You have to drink red wine. While moderate red wine consumption with meals is traditional in some Mediterranean cultures, it is not a required component of the diet. The main focus is on the food pattern.
• Myth: It’s a low-fat diet. The Mediterranean diet is not low in fat, but it prioritizes unsaturated fats from sources like olive oil, nuts, seeds, and fatty fish, while limiting saturated fat.
