The time of drinking milk also has a certain influence on the digestion and absorption of nutrients in milk. The time for children to drink milk depends on the times, time and quantity of drinking milk every day, and adults should pay attention to the time for drinking milk.
Some adults have the habit of drinking milk in the morning, which is unscientific. The reason is that after a night's sleep, people's stomachs have already been emptied, ready to eat and digest food. At this time, their stomachs are also emptied quickly. Milk is liquid milk, so their stomachs are excreted faster. Drinking milk on an empty stomach is discharged into the intestine before it is fully digested and absorbed in the stomach, leading to the loss of nutrients. Milk is rich in high quality protein. The main function of these protein is to form new tissues of the human body, and at the same time to repair the original tissues. If you drink milk on an empty stomach, not only will the milk be quickly discharged from your stomach, but the above-mentioned precious protein will also be decomposed by the human body and consumed as heat, which will not give full play to the due role of protein. I'm sorry.
Protein in milk is digested and decomposed into various amino acids by pepsin and small intestine in human stomach, and then it can be absorbed and utilized in small intestine. Drinking milk on an empty stomach makes some protein not break down into amino acids, and some amino acids are discharged into the large intestine before being absorbed by the small intestine. In the large intestine, these protein and amino acids are decomposed into substances harmful to human body, which makes the precious protein unable to play its due role. It also increases the burden on the human body.
To change this situation, first do not drink milk on an empty stomach in the morning, but drink milk after breakfast 1-2 hours later. There is food in the stomach to prevent the shortcomings of drinking milk on an empty stomach; Second, eat some starchy food before drinking milk, such as steamed bread; Third, when drinking milk in the morning, we should eat some starchy foods such as steamed bread, rice, bread, biscuits and snacks, so that milk can stay in people's stomachs for a long time, milk and gastric juice can be fully hydrolyzed, and protein can be well digested and absorbed.
Milk has hypnotic and sedative effects. Morning is a time for people to study and work energetically. Drinking milk will make people 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.
When is a good time to drink milk? It is best to drink milk at night, because milk contains L-tryptophan, a biochemical substance that can make people feel tired and sleepy, and a small amount of morphine, all of which have certain sedative and hypnotic effects, especially L-tryptophan, which is the main raw material for the brain to synthesize hydroxyl color. Serotonin plays a key role in brain sleep, which can temporarily inhibit brain thinking activities, thus making people want to sleep without any side effects. Moreover, milk can be absorbed on the stomach wall, and calcium in milk can also eliminate tension.
Drinking milk before going to bed is beneficial to the body's absorption and utilization of calcium. Most of the calcium taken in dinner is absorbed and utilized by the human body before going to bed. After sleep, especially after midnight, the level of blood calcium will gradually decrease, and the decrease of blood calcium will promote hyperparathyroidism. Hormones will act on bone tissue, so that part of calcium in bone tissue will be dissolved into blood, and the stable balance of blood calcium will be maintained. This dissolution is a self-regulating function of human body, which will become one of the causes of osteoporosis after a long time. Drink milk before going to bed at night. Calcium in milk can be slowly absorbed by blood, and blood calcium can be supplemented to maintain the balance all night, so there is no need to dissolve calcium in bones to prevent bone loss and osteoporosis. Therefore, drinking milk before going to bed is beneficial.

1. How much milk should each person drink every day?
As a kind of food with high nutritional value, it is difficult to play its due role when drinking less, and it is difficult to digest, absorb and utilize when drinking too much. The daily milk consumption should be determined according to age, work consumption and economic conditions. Generally speaking, adults should drink 400 ~ 500ml, that is, two bottles (two bags) of milk a day, but at least 250ml, that is, one bottle (one bag) of milk. Economic conditions allow the best three bottles (three packs), which is about 750 ml, but it is best not to exceed 1000 ml. Simply put, it means "guarantee one bottle and strive for two bottles, preferably three bottles and no more than four bottles".
How about yogurt?
Yogurt is a dairy product with special flavor after ordinary milk is fermented by lactic acid bacteria. Some vitamins and bioactive substances can be added, and the nutritional components are more perfect than milk, which is more conducive to digestion and absorption. The live lactic acid bacteria in yogurt can also promote the harmonious balance of human intestinal flora and the excretion of toxic and harmful substances, which has certain disease prevention and health care functions. Some people call it "intestinal scavenger", while others describe it as "sour and sweet, feeling like first love". However, it should be noted that it should not be heated before drinking, taken together with antibiotics or fed to infants.
