I'm middle of the road on Longo, and that's just strictly due to his recommendations as they apply to me. Homer would definitely benefit by following Longo's advice.

The story about Italian children being overweight applies to almost every country today due to diets with a carbohydrate imbalance. Anointing the undefined but exotically labeled Mediterranean diet as the nutritional answer for the world's health issues is so wrong in many ways. I can eat foods that are very unhealthy for me and still call it a Mediterranean diet.

One last thought and question: Why is there no group like Peta who find people following a pescatarian diet morally and ethically objectionable? Is it because fish are not mammals and harder for people to interpret as sentient beings?
