Stay away from nine foods that really cause cancer

When talking about the rumor that food causes cancer, Professor Ma Liping, vice president of the Guangxi Nutrition Society, was deeply touched. "Almost every once in a while, friends and relatives call and ask me whether eating a certain food will cause cancer. It makes me, who deals with food every day, feel helpless." Ma Liping said that we can simply divide food into three types: animal food, plant food and processed food. For the fresh, pure animal food and plant food that we often eat, humans have been eating them for thousands of years, and there is almost no possibility of causing cancer.

Carcinogens in daily life

Medical research has found that there are more than 10 chemical substances that are carcinogenic, among which nitrosamines, benzopyrene and aflatoxin are recognized as the three major carcinogens, and they are all closely related to diet.

Nitrosamines can cause tumors in almost all organs of the human body, among which digestive tract cancer is the most common. Nitrosamine compounds are commonly found in grains, milk, cheese, tobacco, alcohol, bacon, grilled meat, marine fish, canned foods and drinking water. Unfresh foods (especially vegetables that have been cooked for a long time) contain higher levels of nitrite.

Benzopyrene is mainly produced during the combustion of coal, oil, natural gas and other substances. Fats, cholesterol, etc. can also form benzopyrene at high temperatures. For example, the benzopyrene content in smoked products such as sausages can be 60 times higher than that in ordinary meat. It has been proven that long-term exposure to benzopyrene can not only cause lung cancer, but also digestive tract cancer, bladder cancer, breast cancer, etc.

Aflatoxin is the most potent carcinogen known. Medical scientists believe that aflatoxin is likely an important cause of liver cancer. In some areas with a high incidence of liver cancer, people often eat fermented foods such as fermented tofu and bean paste. If these foods are not produced properly during the production process, aflatoxin can easily be produced.

Nine types of real carcinogenic foods to stay away from

Ma Liping said that people should have their own judgment regarding the rumors that "food causes cancer" and should never believe everything they hear. If they hear that a certain food can cause cancer, they should never touch it again. When you encounter rumors that "food causes cancer", you can first ask yourself these questions. For example, "How high is the toxic substance content in this food?", "Do I eat this food for every meal? Do I eat a very large amount?" You can seek help from professionals while looking up relevant information. In addition, in daily life, green leafy vegetables and dark-colored fruits and vegetables are good anti-cancer foods and you can choose more of them.

"Food causes cancer" is mostly a rumor, but there are also some unsafe factors in food.

1. Pickled food: The dimethyl nitrite produced by salted fish can be converted into the carcinogen dimethylnitrosamine in the body. Salted eggs, pickles, etc. also contain carcinogens and should be eaten as little as possible.

2. Barbecue food: roast beef, roast duck, roast lamb, roast goose, roast suckling pig, roast lamb kebabs, etc., should not be eaten too much because they contain strong carcinogens. High-temperature frying not only destroys the original nutrition of food, but also causes food to produce chemical carcinogens such as benzopyrene.

3. Smoked foods: such as smoked meat, smoked liver, smoked fish, smoked eggs, smoked tofu, etc. contain the carcinogen benzopyrene. Frequent consumption can easily lead to esophageal cancer and gastric cancer.

4. Fried foods: When fried and over-cooked, polycyclic aromatic hydrocarbons, a carcinogenic substance, are produced. When coffee is burnt, benzopyrene increases 20 times. Fried pancakes, stinky tofu, fried taro balls, fried dough sticks, etc., most of which use re-used oil, which will produce carcinogens at high temperatures.

5. Moldy substances: Foods such as rice, wheat, beans, corn, and peanuts are easily affected by moisture and mold. When contaminated by mold, they will produce the carcinogenic toxin aflatoxin - aflatoxin. In addition to causing acute poisoning such as abdominal pain, vomiting, and diarrhea, the toxins produced by spoiled food also have more serious potential hazards.

6. Overnight cooked cabbage and sauerkraut: They will produce nitrite, which will be converted into carcinogenic nitrosamines in the body.

7. Betel nut: Chewing betel nut is a factor causing oral cancer.

8. Repeatedly boiled water: Repeatedly boiled water contains nitrite, which produces carcinogenic nitrosamines after entering the human body.

9. Foods containing multiple additives: Especially for children, long-term and excessive intake of food additives will pose a threat to their growth, development and physical health.
