Because drinking too much wine has great side effects and alcohol is harmful to the liver. After being absorbed by the gastrointestinal tract, alcohol is converted into acetaldehyde in the liver by the action of alcohol dehydrogenase, then acetic acid is generated, and finally it is decomposed into carbon dioxide and water to be excreted. However, if you drink too much, acetaldehyde in your body cannot be converted into acetic acid. Acetaldehyde is a highly toxic substance, which will produce a large number of superoxide anion free radicals, and the human body will be drunk or alcoholic. Accumulate over a long period, causing great harm to the body. People who drink too much for a long time will have fatty liver, hepatomegaly, hard texture, yellow color and lose normal function. Every healthy adult has a certain ability to decompose and digest alcohol, but each person's ability to relieve alcohol will be different due to his innate genetic constitution, whether he often drinks alcohol, his age and his health and psychological status at that time. Generally speaking, the higher the alcohol content of wine, the lower the alcohol consumption. The total amount of white wine, yellow wine 100 ml, red wine 150~200 ml and beer/500 ml should be controlled in a day.
