Generally, air-dried bacon will not cause cancer, because the air-drying process is only a natural air-drying process, and the bacon sold in the market belongs to the industrial production of bacon. In order to improve production efficiency, it is usually smoked at high temperature, and the wood materials used for smoking are poor. When the temperature exceeds 300℃, the barbecue will drip oil, resulting in thick smoke. There are a lot of polycyclic aromatic hydrocarbons in the thick smoke, which is a harmful chemical substance, among which benzopyrene is a strong carcinogen. In addition, in order to prolong the shelf life of bacon and keep the taste fresh, most merchants will add a lot of salt to bacon, which will be converted into nitrite (also known as sodium nitrite). Nitrite is also a carcinogen, and it will definitely cause cancer if it stays in the body for a long time. Bacon, whether it is a vegetable market or a supermarket, is an "industrial product" made of smoke and salt. Eating too much will inevitably lead to malignant diseases such as cancer. According to the survey, many areas that love to eat bacon are also high-risk areas of gastric cancer, and bacon will also increase the risk of fatty liver. For patients with hypertensive heart disease, eating bacon is easy to raise blood pressure; Patients with high cholesterol can also cause blood vessel blockage. People suffering from hemorrhoids should also pay attention to the fact that bacon contains more salt, which is easy to increase the blood pressure of venous network and aggravate the pain of hemorrhoids after intake. Patients with kidney disease are also forbidden to eat too salty, and it is best not to touch bacon. If excessive sodium accumulates in the body and cannot be discharged, it will lead to edema. Cancer is a typical multifactorial chronic disease. In addition to carcinogens, their own genes are also very important reasons. Moreover, a balanced diet can also reduce the risk of cancer.
