According to the research of medical experts, milk contains two kinds of hypnotic substances unknown to people in the past, one of which is tryptophan synthesized by serotonin, which can promote sleep. Because of its function, people often only need a glass of milk to fall asleep. Therefore, if they drink milk in the morning, it will inevitably inhibit people's cerebral cortex and affect their work and study during the day. In addition, drinking milk in the morning is not conducive to digestion and absorption. This is because the protein of milk can be absorbed by the human body only after it is decomposed into amino acids in the stomach and small intestine. In the morning on an empty stomach, the emptying of the stomach and intestines is very fast, so the milk is discharged to the large intestine before it can be digested. Furthermore, protein absorbed in food can only form a part of human tissues on the basis of sufficient heat. If the heat is insufficient, the absorbed protein will soon become heat and be consumed, which is undoubtedly a waste of overqualified materials. Therefore, nutrition experts believe that it is best to drink milk in the evening or half an hour before going to bed.
Drinking a glass of milk for children before going to bed can promote their height development and improve their resistance. The peak of auxin secretion is one hour after the child falls asleep, and the growth hormone in the body is released the most during the night sleep, and the bones grow fast. Milk is like a calcium donor who gives charcoal in the snow, allowing rich calcium to enter the body in time and reach the growth site of bones, promoting the calcification and maturity of new bones, which not only enhances resistance, prevents diseases, but also promotes the growth of children, and finally achieves a strong nation. Drinking a glass of milk before going to bed, the rich calcium and VD in milk echo the auxin in the body, which can promote the child to grow taller. Morning and evening are the best time to drink milk, and drinking milk at breakfast provides sufficient nutritional guarantee for the vitality of the day; Drinking milk at night will not only help you sleep, but also help your body absorb its nutrients.
