Professor Cole of Freiburg Medical College in Germany pointed out that comparing the calorie content of beer, wine and champagne, we can see that the calorie content of beer is the smallest. This conclusion may surprise many people. So it can be said that beer is not the chief culprit of beer belly. The appetizing function of wine is the main cause of beer belly. Because this function of wine can promote the secretion of saliva and the formation of digestive juice, make the food in the mouth easier to digest and make drinkers eat more than non-drinkers. In other words, people will consume excess nutrients because of drinking, and the body will accumulate fat layers, and the abdomen is the easiest place to accumulate fat, thus forming a beer belly. The researchers also pointed out that drinking beer in moderation will not increase weight, but may also reduce weight, because alcohol can promote fat burning. In addition, beer can promote the burning of fat and sugar. Beer also affects blood coagulation and blood pressure. For example, beer can reduce the content of low density lipoprotein cholesterol (LDL) and increase the content of high density lipoprotein cholesterol (HDL) in blood. This can play a positive role for people who are engaged in physical exercise and can eat reasonably.
