　　How about a cold beer?

　　Drinking cold beer before meals can easily cause the temperature in the gastrointestinal tract to drop suddenly, blood vessels to rapidly contract, and blood flow to decrease, causing physiological dysfunction and affecting normal meals and the digestion and absorption of food.

　　At the same time, it will also reduce the secretion of gastric acid, pepsin, small intestinal amylase, and lipase in the human body, leading to digestive disorders.

　　The gastrointestinal tract is stimulated by supercooling, which causes accelerated peristalsis and dysmotility. Over time, it is easy to induce stomach ache、diarrhea and nutritional deficiencies.

　　So it is not advisable to drink cold beer.
