I feel like the word "Mediterranean diet" is something I've never seen defined to my satisfaction. I know it includes lots of vegetables and olive oil, and not much meat. I have yet to see anything prescriptive. As in, here's a diet plan with recipes and calorie counts, follow this, from any highly respected medical source. Do people fry food in olive oil along the Mediterranean or is it only eaten fresh? In fact, I'm not even certain that I can buy olive oil anywhere locally, but rather everything labeled olive oil may be something else.
