"Dietary Guide for China Residents" suggests: "Smoked fish, bacon, ham and other foods need to be smoked with smoke generated by stewing wood chips and other materials, so as to improve their antiseptic ability and make the food have a special flavor. However, the smoke contains carcinogens such as benzopyrene, which is easy to pollute food and must be vigilant. "
Therefore, although smoked fish, bacon, ham and so on. Although its unique flavor is loved by people, the guide still regards it as "food that can be tasted but should not be eaten more".
In view of the increasing incidence of cancer in China in recent two or three years, from the perspective of cancer prevention, Chinese people should try to stay away from processed foods, such as smoked fish, bacon, ham, smoked fish, bacon, ham and so on.
Foods preserved with high concentration of salt can prevent the growth of microorganisms and prolong the shelf life. Such as salted fish, pickles and so on.
The harm of these foods is not only cancer-causing, but also other hazards if pickled improperly. For example, if the salt concentration is not high enough, it will easily lead to mildew and deterioration of pickled vegetables or meat; If the salt is put too little and the curing time is too short, nitrite harmful to human body may be produced. When people ingest too much nitrite at one time, an acute food poisoning called enterogenous cyanosis will occur, with symptoms such as dizziness, fatigue, dyspnea and purple lips, and in severe cases, they will die of lack of oxygen.
Some people are used to adding different amounts of salt to pickled Chinese cabbage, which is often eaten by northeast people in winter. The content of nitrite in pickled Chinese sauerkraut was the highest on the 8 th day. In order to avoid and reduce the intake of nitrite through pickled vegetables, usually pickled vegetables should be eaten at least 27 days later. One way to reduce the nitrite content in pickled vegetables is to add a proper amount of vitamin C to the pickled water during the pickling process.
The guide to the consumption of snacks for young people in China issued by the Nutrition Society of China has put some snack foods on the list of "restricted consumption", that is, these foods can only be eaten occasionally and tasted occasionally, and should not be eaten frequently. They are: fruit candy, milk candy, jelly, cotton candy, preserved fruit, ice cream, ice cream, potato chips, French fries, fried chicken wings, puffed food, high-sugar carbonated drinks and so on.
The reason is that these foods are low in nutritional value, high in fat, sugar and salt, and lack other nutrients needed by the human body. Many products also contain excessive intake of pigments, sweeteners, other food additives and trans fatty acids, which will increase the risk of obesity and other chronic diseases. Therefore, they are also "foods that can be tasted but should not be eaten more".
In this regard, I am afraid that no one has made an investigation so far. However, obviously, eating 50 grams is less harmful than eating 100 grams, and tasting 1 time a year is less harmful than eating 1 time a month. In other words, we should try to stay away from it. Here, it is necessary for the author to advise you that if you really put health first, then, on the premise that all kinds of food are generally sufficient, you should eat as little as "0".
I really hope you and your family can do it.
