According to the research of American and British medical experts, milk contains two hypnotic substances that were not known before. One of them is tryptophan synthesized by serotonin, which can promote sleep. Because of its function, people often only need a glass of milk to fall asleep. The other is natural morphine, which has similar anesthetic and sedative effects. Therefore, if you drink milk in the morning, it will inevitably inhibit people's cerebral cortex and affect work and study during the day. In addition, drinking milk in the morning is not conducive to digestion and absorption. This is because protein in milk can only be absorbed by human body after it is decomposed into amino acids in stomach and small intestine. In the morning, on an empty stomach, the stomach empties quickly, so the milk is discharged into the large intestine and has not been digested. Furthermore, protein absorbed in food can only form a part of human tissues on the basis of sufficient calories. If the heat is insufficient, the absorbed protein will soon become heat and be consumed, which is undoubtedly a waste of overqualified materials.
Therefore, nutrition experts believe that it is best to drink milk at night or half an hour before going to bed.
Avoid misunderstanding when drinking milk.
Milk is rich in nutrition, which not only contains essential amino acids, but also contains high-content and easily absorbed calcium. Drinking it for a long time is very beneficial to your health. However, you must pay attention to the way you drink milk. The following are the common misunderstandings of drinking milk, which you must pay attention to avoid-drinking milk on an empty stomach will increase intestinal peristalsis, shorten the retention time of milk in the stomach, and make the nutrients in the body unable to be fully absorbed and utilized. It is best to drink milk with some starchy foods, such as steamed bread, bread, corn porridge and beans, which are beneficial to digestion and absorption.
Improper food mix
Milk should not be eaten with foods containing tannic acid, such as strong tea and persimmons. These foods easily react with milk and agglomerate, which affects digestion.
Preference for highly processed milk
The nutritional value of highly processed milk is not necessarily better than that of fresh milk.
