The relationship between food and cancer is complex, but it is also very important. It is important because about 30% of all cancer deaths are related to dietary factors; when it is complicated, it is manifested in two aspects: on the one hand, harmful ingredients in food have carcinogenic and cancer-promoting effects, and on the other hand, they are nutritional. Substances have a role in fighting cancer and preventing cancer.
Three general cancer substances in daily life:
Medical studies have found that there are more than 10 kinds of chemicals that have carcinogenic effects, among which nitrosamines, benzopyrenes and aflatoxins are recognized as the three general cancer substances. They are all closely related to diet.
Nitrosamines can cause almost all human organ tumors, of which gastrointestinal cancer is the most common. Nitrosamines are commonly found in cereals, milk, cheese, tobacco, bacon, grilled meat, marine fish, canned food, and drinking water. Fresh foods (especially those that have been cooked for long periods of time) contain high levels of nitrite.
Benzene oxime is mainly produced in the combustion process of coal, petroleum, natural gas and other substances. Fat, cholesterol, etc. can also form benzopyrene at high temperatures, and benzopyrene content in smoked products such as sausages can be 60 times higher than ordinary meat. It has been verified that long-term exposure to benzopyrene causes lung cancer, gastrointestinal cancer, bladder cancer, and breast cancer.
Aflatoxin is the most known carcinogen. Medical scientists believe that aflatoxin is likely to be an important cause of liver cancer. In some high-risk areas of liver cancer, people often eat fermented foods such as fermented bean curd, bean paste, etc., such foods in the production process, such as improper methods, prone to aflatoxin.
Carcinogenic Food List:
Carcinogenic foods 1. Pickled foods: Dimethyl nitrite produced by salted fish can be converted into carcinogenic dimethyl nitrite amine in the body. Salted eggs, pickles, etc. also contain carcinogenic substances and should be eaten as little as possible.
Carcinogenic food 2, barbecue food: roast beef, roast duck, roast lamb, roast goose, roast suckling pig, mutton string, etc., because it contains strong carcinogens should not eat.
Carcinogenic foods 3, smoked foods: such as smoked meat, smoked liver, smoked fish, smoked eggs, smoked tofu, etc. Containing benzopyrene carcinogens, eat often susceptible to esophageal cancer and gastric cancer.
Carcinogenic foods 4, fried foods: fried coke, resulting in carcinogenic polycyclic aromatic hydrocarbons. After coffee burns, benzopyrene increases 20 times. Fried pancakes, stinky tofu, fried oyster shank, fried fritters, etc., because most of the oil is used repeatedly, it will produce carcinogens under high temperature.
Carcinogenic foods 5, mildew substances: rice, wheat, beans, corn, peanuts and other foods susceptible to moisture mildew, fungal contamination will produce carcinogen - aflatoxin.
Carcinogenic foods 6, overnight cooked cabbage and sauerkraut: will produce nitrite in the body will be transformed into carcinogenic nitrite amine.
Carcinogenic food 7, betel nut: chewing betel nut is a factor causing oral cancer.
Carcinogenic food 8, repeatedly boiled water: repeatedly boiled water containing nitrite, enter the body to generate carcinogenic nitrite amine.
Carcinogenic foods 9, ham + lactic acid drinks: ham, bacon, etc. in sandwiches and lactic acid beverages are prone to cause cancer. In order to preserve meat products, food manufacturers add nitrates to prevent food spoilage and botulinum growth. When the nitrate hits an organic acid, it turns into a carcinogen nitrite amine.
