There are 21 countries that touch the Mediterranean Sea: Albania, Algeria, Bosnia and Herzegovina, Croatia, Cyprus, Egypt, France, Greece, Israel, Italy, Lebanon, Libya, Malta, Monaco, Montenegro, Morocco, Slovenia, Spain, Syria, Tunisia, and Turkey.
However, the Mediterranean Diet is based primarily on the traditional cuisines of Italy, Greece, Spain, and southern France, excluding those of the Eastern European, Middle Eastern, and African countries in the region.
The reason for this can be traced back to the Seven Countries Study. From 1952–1957, American researcher Ancel Keys conducted informal, exploratory studies in seven countries: Italy, Greece, Yugoslavia, the Netherlands, Finland, Japan, and the United States.
Ultimately, Keys and his team concluded that dietary patterns in Italy and Greece were associated with the lower rates of heart disease and all-cause mortality in these countries. So, Keys began to promote this way of eating for better health and lower disease risk (2).
Today, experts are quick to criticize Keys’ research methods. One recent article published in the Journal of Critical Dietetics points out that the study collected data only from men and that, with the exception of Japan, it included only predominantly white populations (3).
The reason non-European cuisines aren’t part of the Mediterranean Diet isn’t that they’re less nutritious but that these countries weren’t included in early research (3).
Overall, experts agree that the Mediterranean Diet is nutritious. It emphasizes whole, plant-based foods (fruits, vegetables, nuts, seeds, legumes, and whole grains), lean protein, and unsaturated fats. This is similar to what the Dietary Guidelines for Americans recommend (4Trusted Source).
But specifically calling out the cuisines of Italy, Greece, Spain, and France isn’t necessarily helpful, and many Mediterranean Diet food lists are lacking in cultural diversity.
“Saying that one region (and really, three or four countries) eats healthy implies that other countries and their cultural foods are not healthy, which can be stigmatizing,” says Shana Spence, MS, RDN, a registered dietitian based in New York City.
The true Mediterranean diet expands far beyond European staples like fish and olive oil.
“Each country and/or cultural group in the Mediterranean region has their own unique food culture and preferences,” says registered dietitian Alice Figueroa, MPH, RDN. “We should not only highlight European countries but also African and Middle Eastern countries.”

Widening our idea of what the Mediterranean Diet looks like can also make it more sustainable and realistic for people, Spence says. “If someone does not have a taste for seafood or olives, this way of eating would not be sustainable.”
Likewise, if someone can’t afford to eat these Mediterranean staples all the time, they may get discouraged and feel like healthy eating is out of reach.
On the other hand, focusing on overall patterns in the Mediterranean Diet, such as eating lots of plant-based foods and choosing unsaturated fats over saturated ones, makes it more flexible and customizable.
“Every culture eats veggies, fruits, and grains,” Spence says. “Adding more of these foods [to your diet] is great, and there are ways to do this without thinking that your particular heritage is incorrect because it’s not celebrated in mainstream media.”
Figueroa also notes that many non-European cultures incorporate similar foods: vegetable curries are a pillar of Indian cuisine, stir-fries are a staple in Southeast Asia, Guatemalan stews are made with lots of veggies and a bit of meat, and Ethiopian food relies heavily on legumes.
While these dishes aren’t necessarily the ones you’ll find highlighted in Mediterranean Diet cookbooks, they contain many of the same foods and nutrients.
Ultimately, ingredients that are staples in Greece, Italy, and Spain may not be accessible or enjoyable for everyone.
But just because you don’t eat fish and olive oil every night doesn’t mean that your eating habits aren’t nutritious or that you can’t reap the benefits of the Mediterranean Diet.
The Mediterranean Diet is indeed nutritious and health-promoting, but its focus on European cuisines excludes many other cultural foods that are equally nutritious.
Instead of trying to follow the Mediterranean Diet to a T, try adopting its overall patterns, such as eating lots of plant-based foods and choosing unsaturated fats over saturated ones.
