Some time ago, during the National Day, Lao Zhang visited his friend Lao Yang's house. The table full of dishes was full of hearty food. The most conspicuous one was a plate of big salted fish in the middle of the table. Because Lao Yang was poor when he was a child, he couldn't eat fish a few times a year, so he couldn't bear to eat a fish during the holidays, so he marinated it into salted fish. This way, it took a long time to store it and you could eat it slowly. My childhood habit has continued to this day. Until now, Lao Yang still pickles a few pieces from time to time, and uses them as side dishes when eating, which is very good for serving.
"Why are you still eating salted fish? Don't you know that salted fish cause cancer? It has been listed as a Class 1 carcinogen," Lao Zhang said in shock.
"Don't talk nonsense. I've been eating it for decades since I was a child. There is nothing wrong with it. You can try it too." Lao Yang said disdainfully.
Will pickled salted fish cause cancer? Can you continue to eat? The pharmacist will explain it to everyone.
Salted fish can cause cancer. When eating, please pay attention to
Will salted fish cause cancer? The answer is yes. Chinese salted fish have been clearly listed as a Class 1 carcinogen by World Health Organization. Class 1 carcinogen refers to substances that can cause cancer. There are 116 kinds of aflatoxin , benzopyrene , alcoholic beverages, coal tar , and coal tar , which are familiar to us, and ranks 96th.
Why do salted fish cause cancer? This is related to its production process. Salted fish, as the name suggests, is a fish marinated with salt. Although it is easy to preserve and not easy to deteriorate, high concentrations of salt must be used during the marination process to dehydrate the fish meat, which is easy to produce nitrites. After nitrite is consumed into the human body, it will be converted into nitrosamines in the gastric acid environment, such as nitrosothimethylamine, which is extremely carcinogenic. In addition, salted fish itself is also susceptible to bacterial contamination.
can you still eat salted fish?
Since salted fish contains carcinogens, it is best not to eat them, but there are many middle-aged and elderly friends with heavy tastes. Eating salted fish has become a habit. If you really can't quit, you should pay attention to the following points when eating:
① Pay attention to intake. Only eat once a week, only a small fish each time, try to minimize the intake of nitrite. Low doses of nitrite will not cause harm to the body.
②Study found that the content of nitrite in pickled salted fish will first rise and then fall, and will gradually rise after just pickling, reaching the highest value in about a week, and the content will begin to decline after 2-3 weeks. Therefore, when eating pickled salted fish, try to choose the salted fish that is marinated for 3 weeks. If it is the salted fish you purchased by yourself, it is impossible to tell the pickling time. Finally, leave it at home for three weeks to eat it to minimize nitrite.
③ Before cooking salted fish, blanch in water or steam it first, pour out the soup and then cook it, which can remove most of the nitrite.
④ When eating salted fish, consuming more fruits and vegetables rich in dietary fiber can effectively reduce the body's absorption of nitrite and reduce its harm to the human body.
, these common foods are actually Class 1 carcinogens
In addition to Chinese-style salted fish, some Class 1 carcinogens often appear on our table. We should be vigilant and identify them on weekdays.
① Aflatoxin
Aflatoxin is one of the strongest carcinogens found so far. If consumed 20 mg at one time, it can even directly cause death in adults. The most important thing is that aflatoxin is difficult to kill, and general disinfection methods have no effect on it. It can only be eliminated if it is in a high temperature environment above 280℃. Therefore, if you encounter foods containing aflatoxin, it is better to throw them away directly. is more likely to contain aflatoxin foods, including moldy peanuts, corn, beans, nuts, etc. Therefore, if you eat moldy peanuts and nuts, you must spit it out in time and rinse your mouth. In addition, wooden cutting board that has been used for a long time is also more likely to grow aflatoxin. Remember to change the sticky board regularly.
②Benzopyrene
Benzopyrene is also a strong carcinogen. After entering the human body, it will be oxidized and activated by liver and lung cells, producing a variety of metabolites, which will cause damage to genes and become cancerous. The main sources of benzopyrene in daily life include cigarette smoke, car exhaust, smoked and roasted foods. In addition, when the oil temperature when stir-frying exceeds 270℃, benzopyrene will also be produced. Therefore, eat less barbecue food, pay attention to the oil temperature when stir-frying, and remember to brush the pot after meals.
③ nitrosamine
nitrosamine is the carcinogen that we mentioned above. In addition to salted fish, , pickles, smoked foods, and other pickled foods, such as bacon , processed sausages, cured meat pickled vegetables, etc., will contain different degrees of nitrite, which is easily converted into nitrosamine in the body and induce cancer. This type of food should be consumed in limited quantities on weekdays.
Of course, although these foods are listed as Class 1 carcinogens, it does not mean that as long as these foods are consumed, cancer will be caused by the effects of many factors. Whether any carcinogen in can eventually lead to cancer, one depends on the toxicity, two, the other depends on the dose, and three, how long it takes to act. Therefore, when facing these foods, there is no need to be too anxious, just face them rationally.
