People in different countries usually have different eating habits. For example, the habit of Japanese eating some animals in the sea is different from that of China. Japanese people generally choose to eat many marine animals raw, such as sashimi. Then this may make people curious. As we all know, if people often eat some raw marine animals, many parasites will be produced in the human body. Then the Japanese often eat raw fish. Why are there no parasites in them? The main reason is that the marine pollution in Japan is not as serious as that in China, so there are not many parasites on some marine animals in Japan, so even if you eat some marine animals often, there will be no parasites.

First, the reason why Japanese people will not be infected with parasites when eating raw fish. The area of Japan is much smaller than that of our country. It can even be said that the whole country of Japan is only equivalent to a province in China. Although the overall area of Japan is not as big as that of China, it has a large ocean. Because Japan has a large ocean, Japanese people prefer to eat marine animals. But we will find a very strange phenomenon. Although Japanese people often eat some marine animals raw, they are rarely infected with parasites. Mainly because when they eat these raw fish, they have destroyed the internal organs of some marine animals, so the raw fish they eat does not contain parasites.

Second, Japan's oceans As we all know, the quality of seawater in Japan's oceans is very good. It is precisely because the quality of seawater in Japan's oceans is quite good that there are few parasites in Japanese marine life. Therefore, Japanese people often eat animals in the ocean raw and will not be infected with parasites.

Third, review that Japanese people eat marine animals without being infected with parasites, mainly because there are few parasites in Japanese marine animals.
