Sausages and bacon are made in different places, some are directly air-dried and some are smoked. The carcinogenicity of smoked products is well known, so bacon or sausage made by smoking method should be eaten less. Of course, eating less doesn't mean you can't eat. Sausages and bacon are delicious after all. As long as you don't eat it often, the harm will not be obvious. It's not a problem to eat properly during the Chinese New Year, but try to eat as little as possible.
The main hazards of sausage food are:
1, which contains one of three carcinogens: nitrite (antiseptic color);
2, containing a large number of preservatives, increasing the burden on the liver.
Sausage contains a certain amount of nitrate, which is harmless to the body, but if it is not completely cured, nitrate can produce toxic nitrite under the action of intestinal bacteria. A large amount of nitrite intake at one time can make the blood lose its oxygen-carrying function, make the human body lack oxygen, and cause poisoning symptoms, such as cyanosis, shortness of breath, dizziness, palpitation, lethargy, etc. Even severe fainting, if not rescued in time, it will be life-threatening. If you suffer from hypochlorhydria, diarrhea, abdominal pain, malnutrition and ascariasis, eating this sausage is more likely to form nitrite and cause poisoning.
