What is the healthiest diet in the world according to area eg Mediterranean chinese japanese etc?

Oh well, I'm Italiana and I can ure that Mediterranean diet is the most complete one and that's why is the best kind of diet and it's even so tasty due to olive oil and use of onion, garlic and chili and fresh chees such as mozzarella and ricotta, with low fats. We use a great variety of pods, pasta, fruit and vegetables and our diet is very complete. In the other hand the asian diet, poor in meat, is rich in soybeans that is very important and they don't use dressings that's why their life is so long. But can they have a toast to life without our fantastic red-antioxidant wine?
