Beer has high water content and can quench thirst; At the same time, the organic acids in beer have a refreshing effect. On the one hand, it can reduce excessive excitement and tension and promote muscle relaxation; On the other hand, it can stimulate nerves and promote digestion; In addition, the content of sodium, alcohol and nucleic acid in beer is low, which can increase the blood supply to the brain, dilate the coronary artery, and accelerate the metabolic activity of the human body through the stimulation of the kidney provided by the blood. Moreover, beer also has the function of "preventing diseases". According to the experiment of California Medical Center, compared with alcoholics and alcoholics, moderate beer drinkers can reduce the chances of heart disease and ulcer, and prevent diseases such as hypertension.
However, although the alcohol content of beer is not high, once it is excessive, the absolute amount of alcohol will increase, which will increase the burden on the liver and directly damage the liver tissue, increase the burden on the kidney and weaken the myocardial function. In the long run, it will lead to heart failure and arrhythmia.
Studies have confirmed that excessive drinking of beer can not only prevent hypertension and heart disease, but also promote the occurrence and development of arteriosclerosis, heart disease and fatty liver. Drinking a lot of beer damages the gastric mucosa, causing gastritis and peptic ulcer, with symptoms such as epigastric discomfort, loss of appetite, abdominal distension, belching and acid regurgitation. In summer, many people like to drink cold beer, which leads to the decrease of gastrointestinal temperature, the contraction of capillaries and the decline of digestive function.

Relevant data also show that patients with atrophic gastritis and urinary calculi. Drinking a lot of beer will lead to relapse or aggravate the disease. This is because the wort of brewing beer contains calcium, oxalic acid, uridine and purine nucleotides. Their interaction can more than double the amount of uric acid in human body, which not only promotes the formation of gallstones, but also induces gout. As I said just now, drinking beer in moderation can prevent diseases, but the extremes meet. If you drink too much, your body's reaction ability will be reduced.
