What should I pay attention to when drinking beer in summer?

The weather in Nanning is hot, and cold beer has become a summer drink for many people. Tan Jiaxiang, a professor of massage in the First Affiliated Hospital of Guangxi University, said that as long as we control the amount of drinking and pay attention to some drinking matters, we can avoid the tragedy of drinking and hurting our health. When drinking, you may wish to pay attention to the following aspects: drinking beer: there is always beer on the table of citizens who eat barbecue in Nanning night market. Tan Jiaxiang said that although the alcohol content of beer is low, there are still three kinds of people who should give up drinking beer. First, people with urinary calculi. Beer contains calcium, oxalic acid and ursolic acid, which may promote the occurrence of kidney calculi. Second, patients with chronic gastritis. Drinking beer due to chronic gastritis can cause gastric mucosal damage. Third, lactating women. Because beer contains barley malt, it can restore milk and inhibit milk production. Soda and wine: Many people like to drink soda and wine. Tan Jiaxiang reminded that drinking soda is not recommended for beer because beer itself has carbon dioxide. If soda is added, excessive carbon dioxide will promote the absorption of alcohol by gastrointestinal mucosa, but it will be easier to get drunk or slightly drunk. Low-alcohol liquor: low-alcohol liquor should not be stored for a long time. Besides yellow rice wine, beer, wine and other low-alcohol liquors are rich in protein and sugar, which easily leads to microbial reproduction, wine deterioration and sour taste. Generally, bottled beer can be stored for 4~5 months, while bulk beer can only be stored for 2~3 days. Drinking too much beer can induce chronic gastritis and increase the fluid burden on the heart, which is called "bovine heart" or "beer heart". In addition, beer contains high calories, which will increase appetite and pile up into a "beer belly". Generally, 1~2 cups per meal is appropriate. After drinking: Don't eat bean jelly after drinking beer. Because the bean jelly contains alum, it can slow down intestinal peristalsis, prolong the residence time of alcohol in gastrointestinal tract, increase the absorption of alcohol, slow down the blood flow, prolong the residence time of dissolved alcohol in blood and accumulate poisoning.
