This is the largest randomized trial to date. The Mediterranean diet has been studied previously in randomized trials but not in a trial as large as this!
It is fascinating that this was a study of more than 7400 individuals who were randomly assigned to 3 different diets. Two were Mediterranean diets enriched with either extra-virgin olive oil or nuts and other Mediterranean foods, both including more than 7 glasses of wine per week. The control diet was a low-fat diet, which some people have argued is not an ideal control. There was very good compliance with the diets in this large number of people for many years. The primary endpoint was death, heart attack, or stroke. There was a very important significant reduction of this cluster endpoint in the Mediterranean diet groups. Particularly noteworthy, even by itself, was the reduction in stroke.
So what does the Mediterranean diet consists of?
The Mediterranean diet is a modern nutritional recommendation inspired by the traditional dietary patterns of southern Italy, Greece and Spain. The principal aspects of this diet include proportionally high consumption of olive oil, legumes, unrefined cereals, fruits and vegetables, moderate to high consumption of fish, moderate consumption of dairy products (mostly as cheese and yogurt), moderate wine consumption, and low consumption of meat and meat products.
