In my hometown, there is a habit of drying bacon every winter. The roofs of every household are covered with bacon, including preserved fish, preserved chicken, preserved duck, sausage and so on. All the meat has been preserved. Nitrite itself does not cause cancer, but what is terrible is that under certain conditions, nitrite will combine with secondary amine in protein to become a strong carcinogen "nitrosamine", which means that the stronger the carcinogen, the more times it enters the human body, and the greater the probability of winning the prize. Hang it outside for a few days and smoke it in a closed oven with cypress leaves. In the smoking process, a large amount of smoke will be produced, which contains strong carcinogens and is likely to be inhaled into bacon. Because of the previous Spring Festival, the living conditions were poor. I can't eat meat a few times a year, let alone cook a lot of bacon sausages. Farmers will also work hard and raise several big fat pigs a year, some of which will be sold for money. Generally, the family will leave one of their own pigs to kill, commonly known as "killing pigs"!

Due to the low level of social productivity and the lack of better storage conditions, it is difficult for people to eat meat all year round. Therefore, making fresh meat into bacon can not only preserve it for a long time, but also replenish protein in time. If you eat too much, it will be bad for your health. Nowadays, the living standard of rural people is too high, and they also know that eating too much bacon affects their health. Now, many people are born with cancer, and many rural people are a little scared. That's why they don't cook bacon. As for bacon, I personally prefer fresh meat.

It is easy to combine with gastric acid in the body, producing harmful substances, causing gastric cancer, esophageal cancer, intestinal cancer and so on. But don't worry too much. If there is not much nitrite in bacon, there is generally no carcinogenic reaction. Therefore, everyone should pay attention to controlling the dosage and not eating too much bacon. Bacon refers to the processed products made by curing meat and baking it (or exposing it to the sun). It has strong antiseptic ability, can prolong the preservation time and add unique flavor, and is a necessary food for Chinese New Year in many places. But some people say that bacon is a cured product, which contains a lot of carcinogens, and eating it will be harmful to the human body.
