Considered one of the best diets in the world for overall health, the Mediterranean diet is also one of the easiest to follow—no cutting food groups! While this style of eating focuses on fruits and vegetables, it includes meat and other protein sources, like fish and legumes, and dairy. You don't have to travel far to enjoy Mediterranean favorites, either; you can make restaurant go-tos like this Classic Greek Salad at home with cucumbers, tomatoes, olives, feta and an easy homemade dressing.
