Olive oil, fish, and vegetables reduce the risk of heart problems. Oh, and not to mention wine.
The study lasted five years and involved about 7,500 people in Spain. Those who ate Mediterranean-style with lots of olive oil or nuts had a 30 percent lower risk of major cardiovascular problems compared to others who were told to follow a low-fat diet. Mediterranean meant lots of fruit, fish, chicken, beans, tomato sauce, salads, and wine and little baked goods and pastries.
