Milk: Some adults have the habit of drinking milk in the morning. This method is unscientific, because after a night's sleep and rest, people's stomachs have already been emptied, and they are ready to eat and digest food. At this time, the stomach is also emptied quickly, and milk is liquid milk, so the stomach can be excreted faster. Drinking milk on an empty stomach is discharged into the intestine before it is fully digested and absorbed in the stomach, resulting in the loss of nutrients. Milk is rich in high-quality protein. The main function of these protein is to form new tissues of human body, but also to repair the original tissues. If you drink milk on an empty stomach, not only the milk will be discharged from the stomach quickly, but also the above-mentioned precious protein will be decomposed by the human body and consumed as heat, which will not fully play the due role of protein. It is a pity.

Protein in milk is digested and decomposed into various amino acids in human stomach by pepsin and small intestine before it can be absorbed and utilized in small intestine. Drinking milk on an empty stomach makes some protein not decomposed into amino acids, and some amino acids are discharged into large intestine before being absorbed in small intestine. In large intestine, these protein and amino acids are decomposed and decomposed into substances harmful to human body, which makes precious protein fail to fully play its due role. It also increases the burden on the human body.

To change this situation, first of all, don't drink milk on an empty stomach in the morning, but drink milk after breakfast 1-2 hours, because there is food in the stomach to prevent the shortcomings of drinking milk on an empty stomach; Second, eat some foods with more starch before drinking milk, such as steamed bread; Third, when drinking milk in the morning, you should eat some starchy foods such as steamed buns, rice, bread, biscuits and snacks, so that milk can stay in people's stomachs for a long time, and milk and gastric juice can be fully hydrolyzed, so that protein can be well digested and absorbed.

Milk has a hypnotic and calming effect. Morning is the time when people study and work energetically. Drinking milk makes people feel sleepy, but it is not good for study and work, so it is best not to drink milk on an empty stomach in the morning.

Yogurt: Wang Lu, deputy director of the Nutrition Department of Beijing Hospital of the Ministry of Health, thinks that it is more beneficial to drink yogurt at night. Because from the point of view of calcium supplementation, because people no longer eat calcium-containing food at night, calcium metabolism is still quietly going on during sleep, so it is necessary to eat a proper amount of calcium-rich dairy products before going to bed. So, which is more beneficial to health than drinking milk or yogurt at night? For most people, milk is a kind of indigestible drink. After drinking it in the morning, it can be digested in the stomach after a day's exercise. After drinking it at night, it is not conducive to human digestion and absorption because the amount of exercise after sleeping is greatly reduced, and people with poor stomach may have indigestion symptoms. Yogurt is different. The lactic acid it contains helps people's intestines and stomach peristalsis at night, so drinking it at night will not only lead to indigestion, but also help prevent constipation.

Director Wang suggested that you should drink yogurt about two hours after dinner, and avoid drinking yogurt on an empty stomach. Because lactic acid bacteria in yogurt are easily killed by gastric acid on an empty stomach, the health care function of yogurt will be weakened.
