As we all know, milk is rich in calcium and other nutrients. Many people like to get up early or drink a glass of milk before going to bed at night. They think it can be better absorbed. When is it better to drink milk? Can I drink milk on an empty stomach? Let's have a look
When is the best time to drink milk
The time of drinking milk has a great impact on human digestion and absorption, so drinking milk should pay attention to the time arrangement. Nutrition experts believe that milk is best drunk in the evening or half an hour before going to bed.
Drinking milk at night is conducive to rest and sleep. Milk contains L-tryptophan, a biochemical substance 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 the brain to synthesize hydroxyl color. Serotonin plays a key role in brain sleep. It can temporarily inhibit the brain's thinking activities, so as to make people want to sleep, And there are no side effects, and the milk sticks to the stomach wall to absorb, and the calcium in the milk can also remove tension.
Drinking milk before going to bed is conducive to the absorption and utilization of calcium. Most of the calcium consumed at dinner is absorbed and utilized by the human body before going to bed. After sleep, especially after midnight, the level of calcium in the blood will gradually decrease. The decrease of blood calcium promotes the hypersecretion of parathyroid gland. Hormones act on bone tissue to dissolve some calcium salts in bone tissue into the blood, so as to maintain the stable balance of blood calcium. This dissolution is the self-regulation function of the human body. Over time, it will become one of the causes of osteoporosis.
Drink milk before going to bed at night. The calcium in the milk can be slowly absorbed by the blood. The blood calcium has been supplemented and maintained balance throughout the night. There is no need to dissolve the calcium in the bone to prevent bone loss and osteoporosis. Therefore, drinking milk before going to bed is good.
Drink milk on an empty stomach
Milk has a hypnotic and sedative effect. It is time for people to study and work energetically in the morning. Drinking milk makes people feel drowsy, which is unfavorable to study and work. Therefore, it is best not to drink milk on an empty stomach in the morning. After a night's sleep rest, people's stomach has already been emptied, and they are ready to eat and digest food. At this time, the emptying of the stomach is also very fast, and milk is liquid milk, so the stomach discharges 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 proteins. The main function of these proteins is to form new human tissues and repair the original tissues. If you drink milk on an empty stomach, not only will the milk be quickly discharged from the stomach, but also the above valuable proteins will be decomposed by the human body and consumed as heat, which can not fully play the role of protein. 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 decomposed and decomposed into substances harmful to the human body, It increases the burden on the human body.
