People who drink alcohol and blush may be caused by the lack of ethanol dehydrogenase and acetaldehyde dehydrogenase in the body. However, there is no specific method to supplement ethanol dehydrogenase and acetaldehyde dehydrogenase in the body. Ethanol dehydrogenase and acetaldehyde dehydrogenase in the body are synthesized by the liver and cannot be supplemented externally. Therefore, they cannot be supplemented by food or medication. When ethanol dehydrogenase and acetaldehyde dehydrogenase are low in the human body, it is often manifested as an inability to drink, and there will be a state of intoxication such as increased heart rate, increased body temperature, and blushing after drinking. Therefore, it is not recommended for people with low ethanol dehydrogenase and acetaldehyde dehydrogenase to drink a lot of alcohol in their daily life to avoid affecting their health. Ordinary people should also strictly limit the intake of alcoholic beverages.
