WHO-recognized 'carcinogenic list', do you have it on your dinner table? May wish to check it out!

In the eyes of many people, most diseases appear for a reason, but there is one disease that is just an exception: cancer!

　　Some people even blindly believe that getting cancer is a matter of luck, and it is related to the causal cycle!

　　But in fact, from a clinical point of view, any disease has a cause that can be investigated and traces to follow. It’s just that compared with other diseases, the causes of cancer are more complicated. It is the result of a combination of factors, including people’s genetics, age, environment and personality, chronic diseases, and exposure to carcinogens . Many aspects.

　　The so-called carcinogens refer to substances that originate from natural and man-made environments and can induce cancer in humans and animals under certain conditions . If divided according to their sources, they can be divided into three types, namely natural carcinogens, carcinogens generated during raw material processing, and synthetic carcinogens .

　　The WHO has published a list of carcinogens, and research experts have classified carcinogens into different grades. Among them, the first class of carcinogens refers to substances that have been identified and have carcinogenic properties to the human body, such as cigarettes, alcohol , etc., which are all in the ranks of the first class of carcinogens . In addition, the following types of food have also been on the list:

****## 　　1. Chinese salted fish

　　As the name suggests, it is a food that has been preserved in salt and air-dried. Although it has a good taste and full flavor, it has the possibility of causing cancer.

　　The reason for this is that in the process of curing meat, nitrite will be produced , which can react with the protein of the pickled variety to produce ammonia , the decomposition product, to form a special substance " nitrosamine" .

　　Nitrosamines themselves are a class of carcinogens , and a large amount of intake and long-term trace intake have the possibility of causing cancer . Clinical studies have confirmed that nasopharyngeal cancer, esophageal cancer, gastric cancer, liver cancer, etc. are all related to nitrosamines;

　　2. Processed meat products

　　The so-called processed meat is the meat that can be preserved for a long time and has a changed taste after being cured with salt, air-dried, fermented, smoked or otherwise treated . For example, the Chinese- style salted fish mentioned above is actually a part of processed meat. kind.

　　On October 26, 2015, the International Agency for Research on Cancer released a report on cancer, which classified processed meat products as a carcinogen based on sufficient evidence to show that the consumption of processed meat and large intestine Cancer is closely related . For every 50 grams of processed meat products eaten in one day , the risk of colorectal cancer will increase by about 18% ;

　　3. Betel nut

　　Betel nut has become the third most addictive consumer product in the world after cigarettes and alcohol. Not only that, the International Agency for Research on Cancer has also classified betel nut into a class of carcinogens . Chewing betel nut for a long time will increase the risk of oral cancer .

The reason for this is mainly related to the crude fiber and alkaloids　　contained in betel nut . Repeated chewing of crude fibers can cause damage to the oral mucosa , and alkaloids can directly damage the cells of the oral mucosa. Under the double influence , the cells are repeatedly damaged and repaired , which in turn increases the chance of cancerous cells in the oral cavity.

　　In addition to the above three types of food, moldy and spoiled food containing aflatoxin, smoked barbecue food containing benzopyrene, fried food containing acrylamide, etc., all have the possibility of cancer after long-term consumption.

　　Although their relationship to cancer is not absolute and is based on long-term, extensive exposure, no one can guarantee that they are the luckiest. Therefore, it is necessary to improve bad eating habits from now on.****
