Professor Williams of the University of Wales in the United Kingdom has made a long-term observation on the role of beer and human body, and concluded that drinking a small amount of beer every day is helpful to lose weight; People who regularly drink moderate beer live longer than those who don't drink beer. A research report recently published by Williams Company shows that the alcohol content of beer is very low, with water accounting for 93%. It contains carbohydrates that promote digestion, protein and vitamins, and contains no fat or sugar. Beer cannot be produced without hops. The ear of this perennial herb can make beer bitter and fragrant, and also has the function of invigorating stomach and diuresis. Drinking beer regularly and in moderation will not make people fat, but also help to lose weight.
