Judging by the picture (since that's all I can see) the mediterranean diet consists of bread, filled pastries, fritters, and dairy-based sauces.
The way I remember it is:
For fats, Olive oil
For snacks, nuts
For calories, whole grains
For fiber, salads
For minerals, Veggies
For protein, Legumes
For protein, Fish poultry
For drinks, Wine and Water
For desert, Fruit
Wrapping all the food in yummy plastic lames was not an option those days
People living more time in the climate that we evolved and feel comfortable is hardly a surprise
