With the development of society, many people's eating habits are more westernized, and it's a waste of time to wake up in the morning to do some breakfast. Many people start their day's work by drinking a glass of milk in the morning. There are different opinions about whether it's good to drink milk in the morning, but what's the good of drinking milk in the morning? Let's have a look!
2. Some adults have the habit of drinking milk in the morning, which is unscientific. The reason is that after a night's sleep, the stomach of the rest person has already been emptied, and they are ready to eat and digest food. At this time, the stomach is emptied very quickly, while the milk is liquid milk, and the stomach is discharged faster. Drinking milk on an empty stomach, which is not fully digested and absorbed in the stomach, is discharged into the intestine, causing the loss of nutrients. Milk is rich in high-quality proteins. The main function of these proteins is to form new tissues of the human body and repair the original tissues. If you drink milk on an empty stomach, not only the milk will be quickly discharged from the stomach, but also the above precious proteins will be decomposed by the human body and consumed as heat, which can not fully play the role of proteins. It is a pity.
3. The protein in milk can be absorbed and utilized in the small intestine only when it is digested and decomposed into various amino acids by pepsin in human stomach and small intestine. When the milk is drunk on an empty stomach, some proteins are not broken down into amino acids. Some amino acids are discharged into the large intestine without being absorbed in the small intestine. In the large intestine, these proteins and amino acids are broken down and become harmful to human body Material, so that the precious protein did not fully play its due role. It also increases the burden on the human body.
4. To change this situation, first of all, do not drink milk on an empty stomach in the morning. Instead, drink milk 1-2 hours after breakfast. There is food in the stomach to prevent the defect of drinking milk on an empty stomach. Second, eat some food with more starch before drinking milk, such as steamed bread; Third, when drinking milk in the morning, you should eat some starch containing food such as steamed bread, rice, bread, biscuit, snack, etc., which can make the milk stay in the human stomach for a long time, and the milk and gastric juice can fully have enzymatic hydrolysis, so that the protein can be well digested and absorbed.
5. When is the best time to drink milk? It's better to drink milk at night, because milk contains a biochemical substance L-tryptophan that can make people tired and sleepy, and a trace of morphine. These substances have certain sedative and hypnotic effects, especially L-tryptophan, which is the main raw material for brain to synthesize hydroxytryptamine. Serotonin plays a key role in brain sleep, which can make brain thinking activity It is temporarily inhibited, so that people want to sleep, and there is no side effect, and the milk can be absorbed on the stomach wall, the calcium in the milk can also clear the tension, so it is more beneficial for the sleep of the elderly, so drinking milk at night is good, which is conducive to people's rest and sleep.
In the above introduction, we know that the habit of drinking milk early is not very scientific, but it is not that there are many disadvantages. Then we can change our habit a little, so that not only the nutrition of milk will not be lost, but also the nutrition of milk will be brought into play!
