Japanese people often eat sashimi, what harm will it do to their health?

First of all, humans can eat meat raw. However, for the sake of safety, meat is rarely eaten again. In the process of human evolution, when there is no normal use of fire, human beings, like other carnivores, eat prey and plants raw. With the skillful use of fire, people gradually changed to eat cooked meat. Then it gradually developed into the current diet mode. In this development process, people of different regions and races will have great differences in diet due to different living environments. In fact, this difference is to meet the needs of the environment, including food types, food richness, food preservation and so on. So humans actually have the ability to digest raw meat.

They can digest and absorb raw meat to meet the needs of the body. For example, some coastal areas will also eat fish, shrimp, crabs, shellfish and other foods raw, while in some pastoral areas, there are even raw beef and mutton. But raw meat can't be eaten casually, and the sanitary conditions must be guaranteed. Parasites and pathogens in meat are terrible and directly threaten life. In addition, if the meat goes bad (no problem with slight deterioration after cooking), resulting in too many bacteria, the risk is also very terrible. Besides, we haven't eaten raw meat for a long time. We are used to cooked food. If you eat raw food suddenly, some people will have obvious food intolerance, causing gastrointestinal discomfort and so on.

Eating vegetables raw may be harmful to people. For example, flour, rice, mushrooms, corn, eggplant, broccoli, etc., must be cooked before being absorbed by the human body. In addition, raw meat can't absorb nutrition well. The human stomach is very different from that of carnivores. People have a small stomach and can only digest cooked food. Raw meat can damage people's stomachs. Raw meat is soft and hard, as well as bacteria, microorganisms and fungi. Eating raw meat will affect and destroy human organs, such as stomach, intestine, liver and gallbladder. Therefore, people invented fire to cook food very early.

Fire can cook raw meat, and people can absorb nutrients well after eating cooked meat. Therefore, both vegetables and meat should be cooked before eating, so as to ensure health. First of all, humans can eat raw meat. Humans first changed from apes to humans and ate raw meat, but the signs that distinguish humans from animals are: making tools and using fire. After mastering the use of fire, I gradually learned to cook raw meat with fire. First of all, it should have a good taste and be easy to store. But now I have been used to it for a long time, and my immune function to bacteria in raw meat has declined, so I am not suitable for eating raw meat.
