Many people believe that people who drink easily blush that the body of alcohol distributed quickly, the more red that the more able to drink. However, compared with ordinary people, people who drink easily blush are more likely to suffer from esophageal cancer. Drinking red people is mainly the body lack of acetaldehyde dehydrogenase, the body’s acetaldehyde can not be metabolized into acetic acid in a timely manner, thus piling up in the body, resulting in blood vessel dilation, redness, rapid heartbeat, dizziness and other symptoms, in fact, this kind of people is not suitable for drinking. More seriously, studies have shown that acetaldehyde is a carcinogenic substance, if acetaldehyde dehydrogenase deficiency, that is, drinking easy to blush people, long-term large amounts of alcohol, so that the body of acetaldehyde for a long time to build up, it is easy to trigger gastric cancer, liver cancer and other esophageal cancers. There is also a group of people whose faces become whiter the more they drink. This group of people is ethanol dehydrogenase and acetaldehyde dehydrogenase are deficient, the beginning of the drink did not have much reaction, but drink later in the body to reach a certain level of ethanol, then suddenly drunk. Due to the lack of both enzymes, the alcohol in the body can not be metabolized, and the accumulation of too much to increase the burden on the liver, resulting in alcoholic liver injury. If the body’s ethanol dehydrogenase and acetaldehyde dehydrogenase are very good, then it is really able to drink. Most of these people tend to sweat and urinate a lot when they drink, because it has something to do with the body’s fast metabolism and the fast discharge of alcohol. Doctor’s note: It is best to eat some food before drinking, or drink at the same time intake of lean meat, beans, eggs, milk and other protein-rich foods and fresh vegetables, can play a role in slowing down the absorption of alcohol, to protect the gastric mucosa. In addition, drinking alcohol in moderation, do not follow the trend, do not take life as a joke.
