The Oldways Mediterranean Diet Pyramid, created in 1993 by Oldways in partnership with the Harvard School of Public Health and the World Health Organization (WHO), serves as a visual guide to adopting a healthy Mediterranean diet. This dietary approach, rooted in the traditional eating patterns of Crete, Greece, and southern Italy around 1960, emphasizes whole, minimally processed foods and has been linked to numerous health benefits. At that time, the rates of chronic disease were among the lowest in the world, and adult life expectancy was among the highest, even though medical services were limited.
Origins and Purpose
In 1993, Americans were focused on avoiding fat, driven by the government's low-fat dietary guidelines. To counter this "fat phobia" and provide a research-backed alternative to the USDA's food pyramid, Oldways convened a group of experts for the International Conference on the Diets of the Mediterranean. The Mediterranean Diet Pyramid emerged from this conference, offering a balanced and flavorful approach to eating.
The Structure of the Pyramid
The Mediterranean Diet Pyramid is structured to illustrate the frequency with which different food groups should be consumed.
Base: Foundation of the Diet
The base of the pyramid emphasizes the importance of physical activity and social connections, recognizing their crucial roles in overall well-being. It also highlights the core foods that should form the foundation of every Mediterranean meal:
- Vegetables and Greens: A wide variety of colorful vegetables and leafy greens.
- Fruits: Fresh, seasonal fruits.
- Whole Grains: Unrefined grains like whole wheat, brown rice, and oats.
- Legumes: Beans, lentils, and other pulses.
- Nuts and Seeds: A variety of nuts and seeds.
- Herbs and Spices: Used generously to flavor foods.
- Healthy Fats: Primarily olive oil.
These plant-based foods are the mainstays of the Mediterranean Diet, providing essential nutrients, fiber, and antioxidants.

Key Components of the Mediterranean Diet
Emphasis on Plant-Based Foods
The Mediterranean Diet prioritizes plant-based foods, providing a wide range of vitamins, minerals, and fiber. These foods are the foundation of every meal, offering both flavor and nutritional value.
Healthy Fats
Olive oil is the primary source of fat in the Mediterranean Diet, providing monounsaturated fats that are beneficial for heart health. Nuts and seeds also contribute healthy fats and essential nutrients.
Fish and Seafood
Regular consumption of fish and seafood, particularly fatty fish, provides omega-3 fatty acids, which are linked to improved cognitive function and heart health.
