The phenomenon of the Mediterranean diet has been known for several years. It has become obvious that the incidence of heart disease in the countries in the south of Europe are lower than in countries in the north. Diet has been the obvious factor explaining this difference. There has been debate about which particular component of the diet is exerting a protective effect. Red wine has been suggested, but the most likely ingredient is olive oil.
Olive oil is a good source of monounsaturated fatty acids.
Perhaps it is the combination of a glass of red wine during a meal that contains a salad with an olive oil dressing that is the key. Eating such a meal in a cafe overlooking the Mediterranean may also help.
