Let's talk about the 1 junk food, that is, fried food, which includes the fried dough sticks that we often eat. Because a small amount of alum is added to the fried dough sticks during the production process, and the alum contains aluminum inorganic substances, this object may cause great damage to brain nerve cells after being absorbed by people's intestines and stomach. What's worse, it is difficult to excrete this substance through normal physiological metabolism, which brings another one. That is to accumulate gradually. If it goes on for a long time, it will be very harmful to the human body, including the possibility of memory impairment, depression and irritability, and even the occurrence of Alzheimer's disease.
The second kind of junk food is pickled, and pickled fish, a kind of food that people often eat, belongs to foods such as cigarettes, because both the fish in pickled fish and sauerkraut, an important part of pickled fish, are pickled. Although the fish is pickled for a short time, it will also produce some nitrite. After pickled sauerkraut, vitamin C has been lost and there is no nutrition at all, but sauerkraut produces more oxalic acid in the pickling process. Because of the high acidity, it is easy to be absorbed by the intestine, and it is easy to form stones in the urinary system when it is excreted by the kidney. In addition, most foods after pickling may produce a lot of nitrates, and nitrates and amines in the human body produce nitrosamines, which forms a carcinogen, which is very harmful to the human body, which is why people often say that pickled foods are easy to cause cancer.
Let's talk about the third kind of junk food processed meat. Processed meat naturally includes bacon, bacon, sausage and other foods that people often eat. Although these foods are preserved for a long time and taste delicious, after these meats are cured, more nitrosamines are produced, and dimethyl nitrosamines will be formed after entering the human body. As mentioned earlier, this is a very strong carcinogen, so this kind of processed meat food is also defined as junk food.
As a last example, because of the space, another junk food defined by the United Nations Health Organization is barbecue food, which includes mutton kebabs that people usually like to eat when shopping, and skewers of incense and other foods. Because of its great fragrance and attractive taste, this kind of barbecue food is generally loved by consumers. However, although this kind of food is very attractive, it will produce a lot of benzopyrene after being grilled with open flame. After entering the human body, it may lead to cancer in the stomach. In addition, most of the barbecue meats are pickled, so these pickled meats will produce nitrosamines, and after entering the human body, they will form dimethyl nitrosamines, which will further form carcinogens. Thus, barbecue foods will be more harmful to the human body.
