How about drinking milk on an empty stomach?
The first point is to drink milk on an empty stomach. Milk can not be fully enzymolysis. The protein in it will soon be converted into energy and consumed. The nutrients can not be well digested and absorbed Some adults have the habit of drinking milk in the morning. This method is unscientific. The reason is that after a night's sleep and rest, people's stomach has already been emptied, and they are ready to eat and digest food. At this time, the stomach is emptied very quickly, while milk is liquid milk, and the stomach is discharged faster Some people may also have abdominal pain, diarrhea and other symptoms. This is because the lactase generated in the body is very few, and a large amount of milk is drunk on an empty stomach. The lactose in the milk cannot be digested in time, but is decomposed by the bacteria in the intestine, producing a large number of gases and acid solutions, stimulating the contraction of the intestine, and causing abdominal pain and diarrhea.
The second point is to drink milk on an empty stomach. Before it is fully digested and absorbed in the stomach, it 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 human tissues and repair the original tissues Third, if you drink milk on an empty stomach, not only the milk will be quickly discharged from the stomach, but also the precious protein above will be decomposed by the human body and consumed as heat, which cannot fully play the role of protein. Some amino acids will be discharged into the large intestine without being absorbed in the small intestine. In the large intestine, these proteins and amino acids will be decomposed and corrupted into substances harmful to the human body, increasing the number of people The burden of the body.
When is the best time to drink milk?
1. avoid fasting.
Experts especially remind that the best time to drink milk is at 8-9 in the morning, which is when the human body needs a lot of nutrition. But at the same time, we must avoid eating on an empty stomach. Many people usually drink a glass of milk on an empty stomach when they eat breakfast at 8-9 in the morning. This is a very unscientific and wrong eating habit.
Milk has a hypnotic and sedative effect. If we drink it on an empty stomach in the morning, we will feel drowsy, which is very bad for work and study.
Therefore, it should be noted that when drinking milk, it is best to match with staple foods, such as bread, steamed bread, nuts, etc., which complement the nutrition in milk and are more beneficial to human health.
2. Drink milk at night
In fact, the best time to drink milk should be in the evening, because milk contains a biochemical substance tryptophan that can make people tired and sleepy. In addition, there are abundant trace morphine substances. All of these substances have good sedative and hypnotic effects, which can promote sleep.
In particular, L-tryptophan in milk is the main raw material for brain to synthesize hydroxy color, and serotonin plays a key role in brain sleep.
Many old people often have insomnia. At this time, they should drink more milk at night. The calcium in it can clear the tension. Therefore, milk is more beneficial to the sleep of the elderly. The best answer to when to drink milk is at night.
3. before going to bed
Before going to bed at night, it is also very suitable for drinking milk, which is not only conducive to improving the quality of sleep, but also has a good calcium supplement effect. This is because the level of calcium in the blood will gradually decrease after sleeping, and the decrease of calcium in the blood will promote hyperparathyroidism. Under the action of hormone, part of calcium salt in bone tissue will dissolve into the blood.
In order to maintain the stable balance of blood calcium. The calcium in the milk can be absorbed by the blood slowly before sleeping, and the blood calcium can be fully supplemented throughout the night.
In this case, we do not need to dissolve the calcium in the bone, so as to help us effectively prevent bone loss, osteoporosis and other common symptoms. So in normal life, you may as well drink a cup of hot milk before going to bed at night.
4. Nutrition waste
Drinking milk on an empty stomach will not only make people drowsy, but also cause a great waste of various rich nutrients in milk. Because the protein in milk will be quickly discharged from the stomach, and the precious protein will be decomposed by the human body and consumed as heat, so it is difficult to play its due role.
The amino acids in milk are discharged into the large intestine without absorption in the small intestine, and even produce some harmful substances.
