Aflatoxin, phenylpropylapyrene and nitrosamines, the three strong carcinogens recognized in the world, do not contain or contain very little in food, but are often contaminated during processing, storage, transportation and cooking.
Aflatoxin mainly exists in moldy grains, oils, peanuts, it is a metabolite of Aspergillus flavus and parasitic Aspergillus, which is extremely toxic and can cause liver cancer, because aflatoxin is a heat-stable chemical, so it is not easy to destroy in the cooking process. The precautionary measures are mainly mildew prevention. However, if the food has become mildew and toxin-producing, appropriate detoxification measures should be taken
As. Peanuts can be used to remove mold grains;
Rice can be rolled and rubbed with water;
Vegetable oil can be used to add alkali to detoxify.
When organic matter and fossil fuels are incompletely combusted, a class of strong carcinogens - polycyclic aromatic hydrocarbons can be produced, and phenylpropyl(a)pyrene is its typical representative, which is widely present in nature. The main ways for it to enter food are:
1) Environmental pollution, soot and automobile exhaust gas contain a large amount of phenylpropyl (a)pyrene, which is transferred to the plant through leaves and roots.
2) Unreasonable processing methods, such as smoking and fire-roasted food, often cause food contamination due to oil dripping and combustion.
3) Oil pollution, oil dripping is often caused by oil dripping during oil extraction and rolling process. (4) Contamination of storage containers, such as beer is often contaminated due to storage in bitumen-coated wine tanks.
5) Directly imported food, contaminated by dust during sales and transportation, can also increase phenylpropyl(a)pyrene.
Phenylpropyl(a)pyrene, with stable chemical properties, is not easy to destroy during cooking, and can cause gastric cancer, glandular cancer, blood cancer, etc. In order to prevent phenylpropyl(a)pyrene from contaminating food, it is necessary to prevent environmental pollution first, and do not plant leafy vegetables and oil crops in industrial areas and highways with serious air pollution.
Secondly, improve the unreasonable smoking and fire roasting process to prevent oil pollution.
In addition, eating more vitamin A and cruciferous plants such as cabbage and radish can prevent the poisoning of polycyclic aromatic hydrocarbons.
There are more than 100 kinds of nitrosamines compounds, different nitrosamines can cause different tumors, the most important ones are esophageal cancer, gastric cancer, liver cancer, and can induce tumors or malformations through the placenta to the offspring, nitrosamines are formed by secondary amines in nitrite and protein, which are widely distributed in nature, and the food with higher content is salted fish, shrimp skin, beer, salted meat and nitrate meat products sausages, etc., and the meat and vegetable filling will also produce nitrous acid if placed for too long. Rotten vegetables contain a large amount of nitrate, which can be decomposed into nitrite by bacteria and saliva, and then combined with the secondary amine in the protein in the stomach to synthesize nitrosamines. When the pH of gastric juice is 3, nitrosamine formation can be inhibited
When the pH value is 5, it can contribute to the formation of nitrosamines.
Therefore, it is necessary to control the amount of nitrite in products, eat less stale salted meat, salted fish, shrimp skin and other foods, take vitamin C to block the formation of nitrosamines, and garlic also has the effect of blocking nitrosamines.
Aflatoxins are the strongest known carcinogens. Peanuts, corn, and wheat become moldy in hot and humid environments, and there is a type of Aspergillus flavus that produces aflatoxins in mildew.

1. Pickled vegetables can be boiled with water, sunshine, hot water washing and other methods to remove the nitroso carcinogens contained in them. Be careful not to reuse the old soup used for pickles.
2. It is best to boil shrimp skin and dried shrimp before eating, or expose it directly to the sun for 3-6 hours to remove the nitroso compounds contained therein.
3. Sausages, bacon and other meat products contain a small amount of nitroso compounds, do not fry them in oil.
4. It is best to boil or irradiate salted fish with water or sunlight to remove nitroso compounds on the surface of the fish body before eating, but it does not cause much damage to the carcinogens in the deep part of the fish body.

Cancer is not something that can be acquired casually, it has to accumulate over time, and there are many carcinogens. There are also some vegetables that will do.
-
Eat more burnt things It is recommended not to think about it, and not to harm others, others and yourself.

Eliminate carcinogens in food, here are the tips.

Carcinogens are difficult to eliminate. You can only eat less, and even if you eat it, you should eat it with fresh fruits and vegetables. Reduces the attack of carcinogens.
Some barbecue foods, such as roast mutton, pork roast duck, roast chicken, roast duck, roast suckling pig, roast lamb skewers, roast beef, etc., these barbecue substances have strong carcinogens, so they should not be eaten more. Some foods that are prone to mold, such as corn, peanuts, can produce carcinogens when they are contaminated with moisture and mold.
Eating some overnight dishes often will produce nitrite, which is converted into carcinogenic nitrite amine in the body, and eating betel nut often will lead to oral cancer, and often and repeatedly boiled water contains nitrite, which will produce carcinogenic substances after entering the human body. Therefore, it is important to eat less.
Eating some pickled foods often will produce nitrite, often eating salted eggs and pickles, etc., all contain carcinogens, you must eat less, do not eat some fishy foods, such as bacon and smoked eggs, smoked fish, etc., it is easy to suffer from esophageal cancer and stomach cancer. Be sure to eat less.
Usually it is some fried food, which produces a lot of carcinogens, especially stinky tofu, fried cakes, fritters, etc., which are repeatedly used many times The oil will produce carcinogens at high temperatures, so you must pay attention to eating less.

Spore powder. Ganoderma lucidum spores are the male and female gametes of Ganoderma lucidum, and they are also the seeds of Ganoderma lucidum breeding offspring, which is the essence of Ganoderma lucidum. The yield of Ganoderma lucidum spores is low, and only 5-10 kg of Ganoderma lucidum spores can be obtained from the production of 100 kg of Ganoderma lucidum.
Inhibits tumors, calms the heart and nerves, lowers blood pressure and blood sugar, promotes sleep, strengthens the spleen and appetizes, nourishes beauty, prolongs life, eliminates fatigue, improves human immunity, and has the effect of strengthening the body and consolidating the foundation.
1 .Reishi lucidum sporolactone A: has cholesterol-lowering effect.
2 .Reshi lucidum sporolic acid A: has a transaminase effect.
3 .Ganoderma lucidum A, Ganoderma lucidum B: has anti-inflammatory effect.
4 .Uracil and uracil nucleosides: can reduce serum aldolase in experimental myotonic mice.
5 .Adenine nucleoside: has sedative, anti-hypoxia and other effects.
6 .Adenine: It has the effects of sedation, lowering serum cholesterol, and anti-hypoxia.
7 .Oleic acid: anti-allergic effect.

(1) Meat products such as sausages and bacon generally contain a small amount of nitroso compounds. Because the content is not high, it can be discarded when eating. However, do not fry in oil, because high temperature can promote the synthesis of nitroso compounds, so that the content of carcinogens such as nitrosopyrrolidine and dimethylthioniamine is increased.
2) Shrimp skin and dried shrimp contain volatile nitroso compounds such as dimethylnitrosamines, so it is best to boil them in water before eating, or directly expose them to the sun for 3 to 6 hours, which can also achieve the purpose of eliminating carcinogens.
3) Salted fish contains a lot of nitroso compounds, so it is best to boil it in water before eating, or use sunlight irradiation to remove nitroso compounds on the surface of the fish.
Because Wang Yibo belongs to a star, a star belongs to a public figure. Their words and deeds will affect the people's judgment of things, so this incident also reminded the stars who endorse products that endorsements must "polish" their eyes.

Why do sunflower seeds cause cancer? Sunflower seeds are a good nut, rich in unsaturated fatty acids and vitamin E, but you can't eat more, a small handful a day is enough, otherwise the fat intake will be too much. >>>More
