This is an important catalyst for the catabolism of these two components, which will increase the uric acid content in blood. Once uric acid cannot be excreted in time, it will be deposited in the form of sodium salt, causing gout or stones. 3. It is not suitable for mixing with liquor. The brewing methods of various wines are different, and the raw materials are also different. The ingredients of various wines are not miscible with each other. If beer is mixed with liquor, it will accelerate the penetration of alcohol in liquor into the whole body, strongly stimulate and harm organs such as liver, stomach, intestine and kidney, and also affect the production of digestive enzymes in the body, reduce gastric acid secretion and accelerate alcoholism.
