1, don't drink raw milk, drink fresh milk and heat it at high temperature to prevent the disease from entering the mouth;

Some people are used to drinking milk on an empty stomach, which is unscientific. Because eating on an empty stomach will make the intestines move quickly. And the protein in milk will be quickly converted into energy and consumed. The nutrients in milk have not been digested. If absorbed, it will be discharged into the large intestine, which will cause waste invisibly. It's best to eat something before drinking milk or drink it while eating.

3. 80% protein in milk is casein. When the pH value of milk is lower than 4.6, a large amount of casein will agglutinate and precipitate, which is difficult to digest and absorb, and even lead to indigestion or diarrhea in severe cases. Therefore, it is not advisable to add acidic drinks such as fruit juice to milk.

Some people like to take medicine with milk instead of boiled water. In fact, milk obviously affects the human body's absorption of drugs. Milk is easy to form a covering film on the surface of drugs, which makes calcium, magnesium and other minerals in milk react with drugs to form water-insoluble substances, thus affecting the release and absorption of drug effects. Do not drink milk before and after taking the medicine 1 hour.

5, it is not appropriate to drink more cold milk, because cold milk will affect gastrointestinal peristalsis, causing mild diarrhea, so that most of the nutrients in milk can not be absorbed and utilized by the human body.
