Hello, it is generally recommended that you don't drink milk on an empty stomach, because drinking milk on an empty stomach may cause diarrhea, especially for people with poor gastrointestinal function. First, not on an empty stomach: 1, it is not good to drink milk on an empty stomach! Because water accounts for a large proportion in milk, drinking more milk on an empty stomach dilutes gastric juice, which is not conducive to the digestion and absorption of food. In addition, on an empty stomach, the intestinal peristalsis is very fast, the speed of milk passing through the gastrointestinal tract is very fast, and the retention time is also very short. Its nutrition is often too late to be absorbed, so it rushes into the large intestine and goes through the motions. Therefore, drinking milk on an empty stomach is not in line with nutrition and hygiene. The ideal breakfast should be a high-calorie meal in protein, and the amount should not be less than the whole day's food intake. Therefore, it is best to drink milk during a nap or before going to bed late, so as to turn disadvantages into advantages and better play its role. If you are used to drinking milk at breakfast, you must also eat some other foods before drinking milk, so that milk can stay in the gastrointestinal tract for a longer time. If you want to drink a bottle of milk for breakfast, you can eat 50 grams of rice or pasta first, then add an egg and a little pickles and dried tofu, and then drink milk, so that milk can be mixed with other foods in the stomach and stay in the gastrointestinal tract for a long time, which is beneficial to the digestion and absorption of its nutrients. Because food provides enough calories, digestion and absorption are slow and sufficient, so that blood sugar keeps at a high level, and you will be full of energy in the morning. Milk can be heated, but not boiled. Because boiling will destroy some vitamins, calcium in milk will form calcium phosphate precipitation, which will affect the absorption of nutrients by human body. Boiling milk also has some knowledge. Most people will add milk to sugar and cook it with fire. This will make lysine in milk react with sugar at high temperature to produce fructosyl lysine, which will not be digested and absorbed by human body, but will be harmful to human health. So you have to wait until the milk is not hot. Experts remind citizens not to drink milk on an empty stomach. It is reported that many people drink milk in the morning, thinking that it can completely absorb nutrition. In fact, drinking milk on an empty stomach will soon be discharged into the large intestine through the stomach and small intestine, so that various nutrients will be excreted before digestion and absorption. The correct way should be to eat something before drinking milk. Hyperacidity leads to degeneration and precipitation of protein, and nutrients are not easily absorbed by the stomach, which can lead to indigestion and diarrhea in severe cases. Therefore, some bread, biscuits and snacks should be accompanied by milk. It can be seen that the main reasons for not drinking milk on an empty stomach are: First, it is easy to cause diarrhea; Second, the absorption efficiency is not high. Because the time through the gastrointestinal tract is too fast. Try to drink milk after meals, which is beneficial to absorption and tolerance. Second, before going to bed: 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.
