Smoked and roasted food
Bacon, smoked fish, roast goose and roast duck are popular foods. In the process of smoking and baking, food is easy to produce polycyclic hydrocarbons containing benzopyrene, which has become carcinogenic food.
Charred food
After protein such as fish and meat is burnt, the brown and black substances produced are carcinogenic; The brown substance produced by heating sugar, burnt rice crust and burnt crust all contain carcinogen benzopyrene. Therefore, when cooking food, we should pay attention to the heat to prevent carcinogens from being generated due to burning.
Fried and fried food
Fried dough sticks, oil cakes, fried peanuts, fried fish pieces, etc., if the oil temperature is too high, many polycyclic aromatic hydrocarbons will be produced, which can cause cancer. Therefore, when frying and frying food, the oil temperature should not be too high.
Food with preservatives added.
In order to prevent food from spoilage, nitrate and nitrite are often added for preservation when making bacon, sausage and canned food. These preservatives will become nitrosamines with strong carcinogenicity when they enter the body. The longer food is stored, the easier it is to produce nitrite. In order to protect human health, the content of preservatives is strictly controlled in a safe range when producing these foods in various countries.
Food with coloring agent
Sour plum soup, soda, sugar-coated haws and cakes sold in the market are often added with synthetic pigments, which are carcinogenic to some extent. Therefore, food should be colored with natural plant pigments.
Foods rich in sugar and alcohol.
Many drinks, cakes or health foods for diabetics often use saccharin instead of sugar. Animal experiments have confirmed that saccharin can cause bladder cancer. MSG is a condiment for daily cooking. Some people think that eating more MSG will also cause cancer, so when cooking, you should put less MSG. Some people abroad advocate not using MSG at all.
Pickled food
Pickled vegetables, salted fish, bacon and other pickled foods will produce a lot of nitrate and nitrite in the pickling process, which will be transformed into nitrosamines with carcinogenic effect after entering the body.
Stale vegetables
Vegetables such as beets, celery and spinach will also produce nitrates if they are stored for too long. About every100g of long-standing vegetables contains 200mg of nitrate, which becomes carcinogenic nitrosamines under the action of gastric acid after entering the body. The fresher the vegetables, the lower the nitrate content, so you should eat more fresh vegetables.
Food with pesticides attached.
Because chemical pesticides are widely used, vegetables and fruits often adhere to organochlorine or organophosphorus pesticides, which are carcinogenic to human body. Therefore, vegetables and fruits should be washed and soaked with water before eating.
Rotten food
After corn, peanuts, butter, bread, cheese, fruits and other moldy deterioration, aflatoxin with strong carcinogenic effect will be produced.
It can be seen that there are many foods that may contain carcinogens in daily life. But why can't everyone get cancer after eating it? The reason lies in the "quantity" of carcinogens entering the body and the anti-cancer immunity of the human body itself. In order to reduce the incidence of cancer, we should try to eat less or not to eat foods that may have carcinogens.
