Everyone likes eating "white and fat" steamed bread very much. For northerners, steamed bread is the main food of life. If there is less steamed bread in a meal, they will feel unsatisfied. However, steamed bread also has the method of eating steamed bread, which is also exquisite. If you eat it wrong, you will be offended.
Many consumers have "lust" and "love white", which is used by some illegal traders and provides a convenient way to kill money.
Nowadays, many steamed bread, flower rolls, steamed buns, vermicelli, tremella and some other water hair foods are sold in the market. They are white in color and have good sensory properties. Why can steamed bread become so white and fat? Why can seafood such as squid become so white and full? It turns out that illegal traders added a kind of food whitening agent called carved white block in the process of production. The chemical name of the carving block is formaldehyde sodium sulfite, which is decomposed into sulfur dioxide and formaldehyde in the process of food processing. Sodium sulfite has the function of reducing and bleaching in food processing, which makes food whiten. One fifth of formaldehyde has the function of antisepsis, so many watery foods can be sold for several days without deterioration. Some illegal vendors add sulfur dioxide and bleaching powder to make steamed bread.
The main component of carved white block is famous formaldehyde. Formaldehyde is a kind of protoplast poison, which has a strong affinity with human tissues and can make protein coagulate and denature and cell tissues die. Experts have found that formaldehyde is also a potential carcinogen, acting on the DNA of cells (deoxyribonucleic acid), which can trigger and induce cell mutations, and ultimately trigger. Some experts think that the amino and hydroxyl groups of formaldehyde nucleic acid combine to make it lose its activity, thus affecting the functional metabolism, causing varying degrees of damage to all organs of the human body, especially the kidney. Long term consumption has a strong carcinogenic effect, which is internationally recognized as a carcinogen. The lethal dose to mice was 800 mg / kg. According to Japanese reports, adding 1 / 10000 formaldehyde to milk can cause death of infants even after taking it for 20 days. Light tea and hot porridge also cause cancer
In a small county and city in Northwest China, many men in their families suffer from oral cancer, but few housewives suffer from it. What's the reason? Is it that women have the potential to resist oral cancer? After field investigation by experts, we found that in many families in this area, the male host is the head of the family, and he always drinks soup first. As a result, he always drank the steaming soup that had just been put on the table. Over time, the male host's risk of oral cancer naturally increased.
In the rural areas of Henan and Shanxi, where esophageal cancer is high, many people like to drink hot porridge, a bowl of hot porridge without eating small dishes. When squatting at the door, the chewing procedure is also free, and a few mouthfuls are quickly drunk. The temperature of this porridge is generally 70 ℃ ~ 80 ℃, resulting in a high incidence of esophageal cancer. Many people have "choking diaphragm disease" (esophageal cancer).
In northern Iran and Kazak, Turkmen, Uzbek and other high-risk areas, people also have the habit of drinking hot tea, and the temperature of drinking tea is higher than that of low-risk areas. The risk of esophageal cancer in the people who drink hot tea and hot porridge every day is twice as high as that in the people who don't drink hot tea and hot porridge. More Puerto Rican patients with esophageal cancer preferred hot coffee than the control group.
Eating too hot food can also cause cancer in other parts of the body. Long term consumption of too hot beverages and foods can lead to pharyngeal, esophageal, gastric and oral cancers, according to a study by the University of Tokyo. The world-famous Dr. ayrola found in the high incidence counties and cities in northern Japan that local residents generally have the bad habit of "eating too hot rice, drinking too hot soup and tea and other drinks".
Why often drink hot tea, eat hot porridge people easy to get esophageal cancer?
This is because too hot drinks and food can damage the soft oral, tongue, pharynx and esophageal mucosa, causing inflammation and mucosal epithelial hyperplasia, and even mucosal ulcer. As time goes on, scalding on the surface of esophagus, stomach membrane and tongue will cause desquamation and blisters. We know that the mucous membrane of esophagus and stomach is much more delicate than other parts of the body surface, and the tolerance temperature is 50 ℃ ~ 60 ℃. If the temperature of food and drinking water exceeds this temperature, the mucous membrane will be scalded. In order to repair the damaged mucosa, the epithelial cells should speed up the proliferation. Often drinking hot tea, hot soup and hot porridge will make the damaged mucosa not completely repaired and burned. So over and over again, over time, the oral cavity, tongue, pharynx and esophageal mucosa will have proliferative pathological changes, thus inducing. If there are some carcinogens in the food, the absorption of carcinogens in scalded mucosa will be accelerated, which will further promote the process of carcinogenesis.
At present, many people like to eat hot pot. When we eat hot pot, if we are too impatient, eat too fast and eat too hot dishes, plus many hot pots are based on spicy spices, it is also easy to damage the oral cavity, esophagus and gastric mucosa, which can also be induced.
, it's scary to hear this name. As we grow older, we are all cherishing our lives. Especially after middle age, we are all looking for the best way to keep healthy. In fact, the best way is to develop good living habits and not to eat overheated food.
