The Meditteranean diet is a funny thing. Several things. There's the diet that people around the Med ate, which was whatever they could get hold of. Life was harsh and people were poor. Then there's the diet as promulgated by people who don't live here. The lack of red meat was a necessity originally, but probably wasn't a bad thing, overall. There's still very little meat consumed, compared to some places, but it is by no means completely absent. Pork is probably bigger than beef and lamb. Goat is less common than lamb.
