We use refrigerators almost every day. It is common to use refrigerators in spring and summer, which can better keep the food fresh. Usually vegetables and fruits can also maintain a longer time, refrigerator for our better life, has brought a lot of convenience. So, is it harmful to use refrigerator? What are the wrong ways to use them? Now let's talk about the improper use of refrigerators can also lead to gastric cancer.
Is improper use of refrigerator easy to lead to gastric cancer?
Before the popularity of refrigerators, people often preserved foods with salting or smoking methods. Such foods contained large amounts of nitrate and nitrite, which could be converted into carcinogenic N- nitroso compounds in the stomach. In this respect, the popularity and proper use of refrigerators reduced the incidence rate of gastric cancer.
However, with the popularity of refrigerators, residents are more likely to eat overnight and returned dishes, and unhealthy eating habits have become a cause of gastric cancer. The refrigerator is not a safe. In the enclosed space of the refrigerator, many bacteria propagate even faster. The overnight dishes in the refrigerator are not kept fresh, but are polluted. Moreover, many vegetables are easy to produce carcinogenic substances after being returned to the pot.
The refrigerator ownership rate of young people's families is significantly higher than that of middle-aged and elderly people. As the pace of work and life is generally accelerated, people can't live without refrigerators all the year round. Long term consumption of foods stored in refrigerators for a long time increases the probability of bacteria invading the stomach. Of course, the incidence rate of gastric cancer tends to be younger, and it is not ruled out related to smoking alcoholics. In addition to paying attention to light diet, eating less pickled food and more fresh vegetables, early screening is also a good way to prevent and treat gastric cancer. The 5-year survival rate of early gastric cancer can reach 95%.
In the screening of early gastric cancer, gastroscopy combined with pathological examination has the highest correct judgment rate and the highest proportion of early gastric cancer found. Painless electronic gastrointestinal endoscopy is the most intuitive and advanced examination method for gastrointestinal tract. Electronic gastroenteroscopy is to send a sensor similar to a micro camera, which can clearly transmit the pathological changes of esophagus, stomach, duodenum and large intestine to the TV screen, and can also clamp multiple tissues or take samples with cell brush for pathological examination, which greatly improves the accuracy of screening.
These refrigerator related operations are dangerous
1. Coke is frozen in the refrigerator
As there are a lot of gaseous substances in carbonated drinks, the solubility of gaseous substances will decrease with the increase of temperature. The cans containing carbonated drinks and beer are airtight, and the volume of the drinks will expand after freezing.
After the carbonated drinks are taken out from the freezer, a large amount of gaseous substances in the drinks will be precipitated in a short time, resulting in the internal pressure of the tank increasing, so it is easy to explode at the moment of opening.
2. Inflammables and explosives are put in the refrigerator
When alcohol, gasoline and other flammable and explosive materials are stored in the refrigerator, because of the small volume in the refrigerator, it is easy to form explosive mixture. If sparks are fired during startup, explosion and fire may occur.
3. Glassware is put in the air outlet of freezing or cold storage room
The glass bottle or glass container can not be placed in the air outlet of the air duct system of the freezing room or the refrigeration room, which will cause the bottle body to burst and cause personal injury.
4. Put other appliances on the refrigerator
Do not place and use microwave oven, rice cooker, voltage regulator and other electrical appliances with electromagnetic induction on the top and around the refrigerator. This is because the electrical appliances with electromagnetic induction will produce electromagnetic interference to the refrigeration system of the refrigerator, which will lead to the chaotic start-up of the temperature controller of the refrigerator, that is, the thermostat is broken. In addition, microwave oven and refrigerator together will cause resonance, not good for equipment.
Refrigerator explosion, although it is a small probability, but this small probability can not be taken lightly, because once it happens, it may endanger life.
