Mediterranean Diet Basics
The Mediterranean diet is a way of eating that emphasizes whole grains, nuts, legumes, and olive oil, supplemented by moderate amounts of fish, dairy, and poultry. Red meats and added sugars are limited or avoided. It is modeled after the eating habits of people in countries like Italy, Greece, Croatia, and Spain in the early 1960s, before the proliferation of fast foods and other highly processed foods.
Decades of studies have found that this type of diet is associated with longer life, along with lower rates of cardiovascular disease, diabetes, cancer, Alzheimer's, and possibly arthritis.
The diet originated from the Seven Countries Study, conducted between 1958 and 1974, and first published in 1978. The study focused on rates of heart disease and stroke, and found that people in countries bordering the Mediterranean sea suffered less from these diseases than people in Northern Europe and the United States, with diet being one of the key factors. The study's findings were refined into a nutrition guide called the Mediterranean Diet Pyramid in 1993, which remains the basis for the Mediterranean diet.
These guidelines recommend a diet of fruits, vegetables, whole grains, beans and legumes, nuts, seeds, and olive oil, eaten in abundance, as the basis for every meal. Fish and seafood should be eaten often, at least twice a week. Poultry, eggs, cheese, and yogurt are eaten in moderate portions, daily to weekly, with red meats and sweets, highly processed foods, refined grains, and butter eaten rarely or not at all.

The Mediterranean diet is a way of eating that emphasizes whole grains, nuts, legumes, and olive oil, supplemented by moderate amounts of fish, dairy, and poultry. Foods like red meats and sugars are limited or avoided. Numerous studies show that the diet is linked to longer life, and lower rates of cardiovascular disease, diabetes, cancer, and Alzheimer's. It may also be effective for weight loss. It can lead to higher grocery bills, and avoiding certain foods can be difficult for some.
