From SBS:
Rich in fruits, vegetables, whole grains, legumes and olive oil, the diet is famed for being low in saturated fats and high in lean sources of protein like fish. Red wine, drunk in moderation, is even a bonus inclusion.
Yet the term ‘Mediterranean diet’ is a bit loose. It’s meant to infer a particular ‘Mediterranean’ identity to a specific cultural dietary pattern. But the fact is, the Mediterranean basin spans 22 countries across Europe, Asia and Africa, and each country along the Mediterranean Sea boasts a different diet, religion and culture.
