Drinking yogurt or milk before drinking is fine. Drinking yogurt or milk before drinking may minimize the discomfort caused by drinking. Excessive intake of alcohol can cause a depressing effect on the nervous system, and yogurt or milk may alleviate the symptoms of intoxication by protecting the gastric mucosa and enhancing the metabolic effect of the stomach. The intake of food before drinking can try to act as a buffer and reduce the contact between alcohol and the stomach mucosa. Dairy products drink into the stomach can cover the gastric mucosa, and the fat content in dairy products is relatively high, and fat is not easily digested and can remain in the stomach for a long time. In addition to dairy products, keeping food in the stomach before drinking can also play a role in protecting the gastric mucosa and reducing alcohol erosion. In addition, yogurt enhances the action of a digestive enzyme in the stomach called ADH, which is an important digestive enzyme for metabolizing ethanol and relieves the toxic effects of ethanol in the blood circulation on the liver, brain and other organs. The lactic acid bacteria contained in yogurt can also promote digestive peristalsis in the gastrointestinal tract, helping the stomach to excrete alcohol and reduce the damage of alcohol stimulation to the stomach.
