I heard that the traditional japanese diets was one of the healthiest and longest life expectency diets around next to the mediterannean diet. It consisted of things such as rice at every meal, pickled plums, noodles, vegetables, soya products, seaweed, miso soup, tofu, fish, sushi, soy sauce and green tea occasionally meat and dairy products. The traditional Chinese diet consisted of vegetables, rice and green tea. The traditional Chinese were poorer. Any other ideas why the traditional japanese diet is so much healthier than the traditional chinese diet?
