Beer, one of the oldest alcoholic beverages, is the third most consumed beverage in the world after water and tea. Beer was introduced to China in the early 20th century, and it is an exotic wine. Beer is translated into Chinese "beer" according to English beer, which is called "beer" and is still in use today.

Beer is made of malt, hops and water as the main raw materials, and is a low-alcohol wine full of carbon dioxide through yeast fermentation. It is called "liquid bread" and is a low-concentration alcoholic beverage. Beer has the least ethanol content, so drinking beer is not only not easy to intoxicate people and hurt their health, but also beneficial to their health. At present, most beer in the world is supplemented with auxiliary raw materials.

On the "Blue Monument" in the Louvre Museum in Paris, the Sumerians in Babylon sacrificed beer to the goddess in the 3rd century BC. In fact, the inventor of beer was Sumerians. 6,000 years ago, Sumerians living in Mesopotamia made original beer from barley malt, but the beer at that time was not rich in foam.

The disadvantages of beer

Because 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 can lead to heart failure, arrhythmia and so on.

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 reflux.

Many people like to drink cold beer in summer, which leads to the decrease of gastrointestinal temperature, the contraction of capillaries and the decline of digestive function. The calorie of beer is not high, so the argument that "drinking beer is easy to produce beer belly" is still controversial.
