People who do not blush when they drink are mainly due to the fact that the metabolic enzymes in their bodies are more abundant and have sufficient activity, so they have a stronger ability to detoxify alcohol.
If the body contains sufficient and active ethanol dehydrogenase and acetaldehyde dehydrogenase, drinking alcohol generally will not blush. These two enzymes can break down alcohol into carbon dioxide and water. On the contrary, if the body’s acetaldehyde dehydrogenase secretion is insufficient, drinkers will blush, when the body’s acetaldehyde can not be decomposed, stagnation in the body, resulting in vasodilatation, so the face will become red after drinking.
Acetaldehyde is harmful to the human body, its excessive aggregation in the body will damage organs and damage DNA, there is also the risk of cancer, so drink red people try not to drink.
In addition, people who don’t blush when they drink alcohol should also pay attention to it, and it is recommended that they try to quit drinking alcohol, otherwise it will hurt their liver or stomach.
