It may be related to the eating habits of the Japanese. In the past, the meat ban started by Emperor Saga lasted for about thousands of years, so the Japanese diet is characterized by light raw and cold vegetarian food. The elements taken in by the teeth and bones are nothing more than calcium and Naturally, animal-based food is the main source of animal calcium. Japan may mainly rely on plant-based and seafood products

It is worth noting that the Japanese like cold food, so they have that kind of morning preparation. I’m afraid Chinese people can’t stand the cold lunch boxes that have been eaten at noon. It’s unrealistic that thousands of years of eating habits don’t affect the body structure, but it’s hard to say that it’s a deformity. On the contrary, I think many Japanese women’s teeth appear to be very strong.
