Drinking before eating seems to have become a habit in daily life, and it is also a rule to entertain guests and friends. In some places, guests are invited to dinner, and there is even a custom of drinking for three rounds without touching chopsticks. In fact, this drinking habit is not good, which is extremely harmful to the body. Before eating, the stomach is empty. If you drink alcohol at this time, alcohol will directly stimulate the stomach wall and esophageal mucosa, thus affecting the function of the stomach or affecting appetite. Some people don't want to eat after drinking, which is the reason. In severe cases, there will be stomach pain or acute gastroenteritis. People who drink usually have this experience. If you drink the same amount of wine, there will be no big reaction if you have food in your stomach. If you drink on an empty stomach before eating, you will feel dizzy and other discomfort. So some people often eat some food at the bottom before going to eat and drink, which is the reason. Because there is food in the stomach, it will reduce the direct stimulation of alcohol on the stomach wall, and also slow down the absorption rate of alcohol, slow down the onset of alcohol and increase the amount of alcohol. Therefore, wine should not be drunk on an empty stomach. It is best to eat before drinking or eat before drinking.
