Metabolic pattern:
The catabolism of alcohol in human body mainly depends on two enzymes: one is alcohol dehydrogenase. The other is acetaldehyde dehydrogenase.
Alcohol dehydrogenase can remove two hydrogen atoms from alcohol molecules and decompose ethanol into acetaldehyde.
Acetaldehyde dehydrogenase can remove two hydrogen atoms from acetaldehyde and decompose acetaldehyde into carbon dioxide and water.
If there are these two enzymes in the human body, it can quickly decompose alcohol, and the central nervous system is less affected by alcohol, so even if you drink a certain amount of wine, there is nothing you can do. In the general human body, alcohol dehydrogenase exists, and the number is basically equal. But there are more people who lack acetaldehyde dehydrogenase.
Due to the lack of acetaldehyde dehydrogenase, alcohol can not be completely decomposed into water and carbon dioxide, but acetaldehyde remains in the body, which makes people feel sick, unconscious and uncomfortable after drinking. Therefore, people who are not good at drinking and drink less than reasonable standards belong to people who are deficient in acetaldehyde dehydrogenase or completely deficient.
For people who are good at drinking, if they drink too much and too fast, which exceeds the decomposition ability of two enzymes, they will also get drunk.

Precautions:
1, drinking a bottle of milk half an hour before drinking, preferably pure milk or sugary, can prevent drunken gastritis and dehydration. Adding sugar or honey to milk can not only promote the decomposition of ethanol, but also protect gastric mucosa.
2. Don't drink on an empty stomach. Because alcohol is absorbed quickly on an empty stomach, people get drunk easily. The best preventive method is to use edible food or milk before drinking, and protect the stomach by using the indigestible characteristics of fat in food to prevent alcohol from infiltrating into the stomach wall.
Don't drink with carbonated drinks when drinking. The ingredients in this kind of beverage will accelerate the absorption of alcohol by the human body.
4, should be slow rather than fast. Ethanol enters the blood 5 minutes after drinking, and the concentration of ethanol in the blood reaches the peak at 30~ 120 minutes. If you drink fast, the concentration of ethanol in your blood will increase rapidly and you will get drunk soon. If you drink slowly, there will be enough time warp ethanol, and the amount of ethanol will be less, so it is not easy to get drunk.
5. Don't mix drinks. Because the variety of wine is different, its various components are also different, and drinking mixed wine is easy to make people feel uncomfortable.
6. Eat more vegetables when drinking. Antioxidants and vitamins in vegetables can protect the liver.
