Barcelona in the American Journal of Epidemiology found that a Mediterranean diet can reduce the risk of death in people who've had a heart attack, curb the risk of stroke, and boost survival in people living with heart disease, they note. In an analysis of more than 40,000 Spanish adults followed for an average of 10 years, researchers found that sticking to a Mediterranean diet significantly reduced the risk of a first heart attack or other heart disease-related event.

Specific components of a Mediterranean diet differ from region to region but, generally, the key features include high consumption of olive oil, plant-based foods such as fruits, vegetables, legumes, whole-grain cereals, nuts and seeds. Fish is favored over other meat sources with relatively low consumption of red meat. Alcohol, especially red wine, and dairy products are used in moderation.
