For the seventh consecutive year, the Mediterranean diet has been ranked as the best overall diet by U.S. News & World Report, surpassing the DASH diet – designed to lower hypertension – and the MIND diet, focused on brain health. The ranking, announced in 2024, underscores the enduring appeal and scientifically-backed benefits of a dietary pattern rooted in the traditional cuisines of countries bordering the Mediterranean Sea.
The diet emphasizes plant-based foods, including a wide variety of fruits, vegetables, and legumes. Whole grains like barley and rice are staples, alongside nuts and seeds. Olive oil serves as the primary source of added fats, replacing saturated fats like butter. While not strictly vegetarian, red meat consumption is limited to approximately three or four times per month, with preference given to fish, poultry, and eggs. Dairy products are typically sourced from sheep or goats rather than cows.
Recent studies continue to validate the health advantages associated with the Mediterranean diet, attributing them to its rich content of fiber, vitamins, high-quality fats, and antioxidant pigments found in plant-based foods. The diet’s effectiveness in preventing chronic diseases that shorten lifespan is a key factor in its sustained popularity, according to experts. It is described as “easy to follow, balanced and flexible,” offering a sustainable approach to long-term health.
The origins of the modern understanding of the Mediterranean diet can be traced back to the 1950s and the work of American physiologist Ancel Keys, who observed the dietary habits of populations in Greece, Italy, France, and Spain. In 1994, the World Health Organization recognized the diet as a nutritional model. UNESCO added it to its list of intangible cultural heritage in 2013, recognizing it as encompassing “a set of skills, knowledge, rituals, symbols and traditions” related to food cultivation, preservation, and consumption.
Beyond simply listing foods, the Mediterranean diet is increasingly understood as a lifestyle. David Katz, a specialist in preventative medicine, describes it as “a giver of love,” emphasizing the enjoyment of whole, primarily plant-based foods. The diet is practiced across a range of Mediterranean countries, including Spain, Italy, Malta, Croatia, Greece, Lebanon, and Turkey, as well as North African nations like Libya, Algeria, Morocco, and Tunisia.
The benefits of the diet extend beyond physical health. The MIND diet, a variant designed to promote brain health, specifically highlights the importance of leafy green vegetables and berries. The flexibility of the Mediterranean diet allows for adaptation to individual preferences and regional variations, contributing to its long-term sustainability.
