Uncle Liu, who lives in Dongguan, is 76 years old and his body has always been good, but he is inseparable from pickles. His daughter advised him to eat less and he didn’t listen. He felt that he had eaten for so many years.
Half a year ago, Uncle Liu’s chest nest was hot, swallowed foods, and he had a sense of obstruction and acupuncture. It continued to not improve for a while. The son quickly took it to the hospital, and it turned out to be early gastric cancer.
Fortunately, it was found that Uncle Liu was discharged after treatment, but the doctor told him to take a regular review and try to eat less pickles as possible.
Some people are inseparable from pickles in three meals a day. They like to mix porridge or bibimbap with pickles, but will it be harmful to the human body when often eating pickles? Is there any risk of carcinogenesis if you eat too much?
First, pickles contain nitrite, which can cause cancer?
Regarding pickled foods such as pickles, the most saying is “high nitric acid content, eating too much can cause cancer, especially may induce gastric cancer, esophageal cancer, etc.” Is it really carcinogenic when eating pickles?
In the World Health Organization International Cancer Research Structure List, pickled vegetables are listed as 2B carcinogens.
The 2B carcinogen refers to a type of substance with limited or insufficient evidence of human carcinogenic evidence, so it is not possible to directly determine that pickled vegetables such as pickles can cause cancer.
However, the pickled vegetables of pickles generally contain nitrite, and nitrite intake may produce nitrosamine, which increases the risk of carcinogenic. And the salt in pickles is also very high, and eating too much will increase the risk of gastric cancer.
In fact, in the process of pickling the pickles, the nitrite content will change. At first, the nitrate in vegetables during the picking period is transformed into nitrite, and the nitrite content will be rising. After that, one reaches one Peak.
At the same time, nitrite in pickles will also have oxidation effects, and the content gradually decreases. It is reduced to less than 10 mg/kg, reaching the edible level.
In addition, nitrite itself does not cause cancer.
The predecessor of nitrite is nitrate. Nitrate is not low in many daily foods and vegetables. Under the action of reducing bacteria or high -temperature cooking, it may be transformed into nitrite.
Nitrite is one of the food preservatives allowed by the country. If it meets the national standard standard, it will not be poisoned.
The real carcinogenic is actually nitrine, nitrite and amine compounds in food, will produce nitrosamine. Excessive intake of nitrosamine will increase the risk of cancer such as gastric cancer, esophageal cancer, and liver cancer.
Second, how to reduce the harm when eating too much or carcinogenic risk?
There are more or less pickles on the tables of many families. There will be a small dish of pickles, with rice, noodles and other staple foods. They are proper meals.
However, long -term pickled vegetables such as pickles will not only increase the risk of carcinogens, but also may cause excessive salt intake, blood pressure height, vegetable nutrition loss, intake of other harmful chemicals, etc. What is the harm?
1. Add more vitamin C
Vitamin C, phenol, flavonoids and other substances can inhibit the synthesis of nitrosamine and nitrite. Therefore, it is necessary to properly consume more vegetables and vegetables containing vitamin C.
2. Pickled enough time to eat
The nitrite content in pickles will slowly decrease over time, reaching the range of edible. Most vegetables can reach a safe level after three weeks of marinating. Time to eat again.
3. Control volume and reasonable cooking
Picky can be eaten, but remember to control the amount. It is best for adults to eat about 50 grams each time, and do not exceed three times a week. In addition, it is necessary to use a reasonable cooking method to eat. It is recommended to clean it before consumption, eat with vegetables, and use garlic, ginger, pepper and other seasonings appropriately.
4. Eat less special groups
Patients with gastrointestinal cancer, people with a family history of gastrointestinal cancer, as well as patients with coronary heart disease, hypertension, stroke, renal insufficiency and other patients, try to eat less.
Third, the common 4 kinds of foods are actually first -class carcinogens, and the dining table is removed as soon as possible
In addition to many people who love to eat, there are some common foods that are first -level carcinogens, which have been proven to have carcinogenic risks to the human body. These foods are recommended to eat less daily.
Processing meat
Like ham, smoked meat, bacon, meat sauce, pickled beef, etc., are processing meat. International cancer research institutions have listed processing meat as a first -class carcinogen.
Machining meat generally needs to be marinated with nitrite or nitrate. Once converted into nitrite compounds, it may cause cancer, increasing cancer risk of bowel cancer, gastric cancer, and pancreatic cancer.
Barbecue, fried
In the process of making foods and fried foods, first -level carcinogens -benzene meal, the longer the carcinogens, the more carcinogens.
Chinese salted fish
Chinese -style salted fish is listed as a first -class carcinogen, mainly because of Chinese -style salted fish, which requires high salt marination, and dehydrated, which will produce nitride compounds and increase the risk of cancer.
Alcohol
Alcohol is related to various cancers such as oral cancer, laryngeal cancer, liver cancer, and esophageal cancer. It has long been listed as a type of carcinogen by the World Health Organization.
In addition to the above 4 kinds of foods, try to eat less, and pay attention to the nutritional balance in diet.
Usually eat more vegetables and fruits, control red meat intake, and eat less burnt food.Remember to drink plenty of water and exercise appropriately, and have a good mentality.As the saying goes, the occurrence of diseases from the mouth, many diseases are related to bad diet. Take pickles. Although it is fast -food, it may cause cancer when eating too much, so you usually eat less.There are also less like processing meat, barbecue, fried food, Chinese salted fish, alcohol, hot food, etc.
