As the old saying goes, "if you eat it, you won't get sick." Do you think this sentence makes sense?

There is some truth in this sentence. The premise needs to be one degree. Nothing is too much. Too much is not enough. Whether it is about hygiene or not, there must be a degree. Then it will backfire and make jokes.

Health classification: the macro environment is the most important. As we know, hygiene can be roughly divided into environmental hygiene, personal hygiene and food hygiene. What I want to talk about here is mainly food hygiene, emphasizing "not solemn, eating without getting sick". The premise is that in a clean natural environment, if there is a problem with the natural environment, then there will be a big problem in adhering to the "not solemn" human health, so the premise is to maintain the ecological environment and a good ecological environment.

Environment is the main reason:

Let me give you an example: Mongolian yurts on the grassland in Inner Mongolia have always been considered as accommodation environments with poor sanitary conditions, and there are boat-shaped houses on Wuzhishan in Hainan. These shabby houses are all examples of unsanitary, but people who used to live here seldom got sick. Stranger still, even if someone operated in Mongolian yurts during the war years, there were few infections, indicating that the grassland environment was good and clean.

Now, when I travel to Inner Mongolia grassland in summer, I occasionally encounter sheep slaughter and various flies on the spot, but herders don't care much. Foreign tourists will not get sick if they eat beef and mutton with flies. In the words of herders, the flies on the grassland are all green food, which is not too harmful. Of course, we are not advocating hygiene, just talking about the importance of the environment.

People who used to live in the countryside picked vegetables and fruits to eat directly and rarely washed them with water. At that time, the environment was good, that is, there was no pesticide or swelling agent, so even if some dust fell, it would not cause too much harm to the body, or the damage was limited. Now fruits and vegetables look clean, but they can't be eaten directly. The main reason is that pesticides and various chemicals are left behind.

Therefore, how to build a safe living environment is very important.

Hygienic standards should keep pace with the times and do as the Romans do: our human body has a strong adaptability to the environment. In order to adapt to the environment, the internal environment will change with the big environment. We often say that "changing water" is caused by the disorder of flora in a strange place. Developing good hygiene habits is more important than anything else, especially in places with poor environment, such as hospitals, stations and crowded public places.

In some cases, there is no problem with the phrase "unclean food does not cause illness". If you have the opportunity to travel to such a place, you can also learn to do as the Romans do and experience it. The so-called hygiene habits and standards in cities are ridiculous here. In the past, I used to drink mountain spring water directly in the dense forest of Wuzhishan in Hainan, and I could also eat wild fruits directly. At most, I washed them with spring water, which was completely out of line with the sanitary habits in the city.
