Beer contains a lot of organic acids, which has a refreshing effect. Moderate drinking can reduce excessive excitement and tension and promote muscle relaxation. The fourth is to help digestion. The main raw materials of beer production are barley, alcohol, hops and polyphenols, which can promote the secretion of gastric juice, excite gastric function and improve its digestion and absorption ability. In addition, it can stimulate the pancreas to secrete insulin and promote glucose metabolism, which is beneficial to diabetic patients. The fifth is diuresis.

Even though beer has many benefits, it will be counterproductive to drink too much. If you drink too much, the alcohol accumulated in the body will damage the liver function, increase the burden on the kidneys, and the myocardial tissue will also have fat cell infiltration, which will weaken the myocardial function and cause tachycardia. Coupled with excessive fluid, increased blood circulation, increased burden on the heart, leading to myocardial hypertrophy, ventricular volume expansion, heart enlargement, forming a "beer heart." In the long run, it will lead to heart failure and arrhythmia. Moreover, excessive drinking of beer can cause alcoholism and liver disease. Physicians also found that people who drink beer are prone to pancreatic cancer. Therefore, medical nutritionists suggest that each person should drink no more than 1.5 liters of beer every day. When drinking beer, we should also pay attention to mastering several "best":

Optimum temperature: 12 degree is better. First, under this temperature adjustment, the unique aroma of beer can be played normally; Second, at this temperature, the carbon dioxide in the wine will work slowly, and the foam will be fine and rich, and at the same time it will bring out the fragrance of the wine. If the temperature is too high, carbon dioxide will soon disappear and the taste will be bad. If the temperature is too low, it will be bad, which will affect the volatilization of aroma and taste bad. Don't put ice cubes in beer, because beer itself is very weak, and putting ice cubes will affect the taste.

Best taste: at least one bite of beer should be above 15 ml, that is, you should gulp down the beer, and don't drink it slowly. If you drink less, you can't fill your mouth. If the wine gets hot in your mouth, it will aggravate the bitterness and you will not feel the unique flavor of beer.

Best environment: Conditionally put it in the refrigerator, generally stored in a cool place to avoid sunlight. Avoid freezing, which will not only affect the taste but also cause explosion. Repeated freezing and thawing is not good for the wine itself.

Best side dish: It is not advisable to have a meal with pickled and smoked food when drinking beer, because it is easy to produce harmful substances. Generally speaking, fruits and light dishes should be eaten at the same time, and peanuts are the best beer and wine dishes.
