After drinking alcohol, alcohol is first catalyzed by alcohol dehydrogenase and turned into acetaldehyde. Then acetaldehyde becomes acetic acid under the action of acetaldehyde dehydrogenase; Finally, acetic acid will participate in many metabolic pathways in the body and be converted into carbon dioxide and water, which will be excreted. Some people will "face up" when drinking, because after alcohol is metabolized into acetaldehyde, acetaldehyde is difficult to decompose into acetic acid due to the lack of acetaldehyde dehydrogenase in the body, so acetaldehyde accumulates in large quantities, leading to blushing.
People who blush after drinking are more likely to get cancer.
Acetaldehyde is the first metabolite of alcohol in human body, which has been listed as a first-class carcinogen by the International Center for Research on Cancer (IARC), and it will attach to DNA molecules and cause cancer. In other words, there is a scientific basis for the statement that "people who blush when drinking alcohol", because such people have more acetaldehyde in their bodies, so they are more likely to get cancer.
In addition, people who drink for a long time are more likely to get esophageal cancer. Alcohol does cause esophageal cancer, and many of his patients have the habit of drinking hard liquor for a long time. Long-term effects of alcohol on esophageal mucosa will cause mucosal damage and easily lead to mucosal malignant lesions, thus increasing the probability of esophageal cancer.
Refer to the above? Cop China-Do you blush when you drink? Not that you can't drink, but that you can't drink.
