How to drink milk is scientific?

Answer: (1) It is best to drink milk at night. Because milk contains a substance that can make people feel tired and sleepy-L tryptophan and a small amount of morphine, these substances have certain sedative and hypnotic effects. L- tryptophan, in particular, is the main raw material for brain to synthesize serotonin, which plays a key role in brain sleep. Can temporarily inhibit brain thinking activities, so that people want to sleep, without any side effects, and milk can be absorbed on the stomach wall. Calcium in milk can also clear the tension, which is more conducive to the sleep of the elderly, so drinking milk at night is conducive to people's rest and sleep. Drink milk before going to bed at night, the calcium in milk can be absorbed by blood slowly, so that blood calcium can be supplemented and the balance can be maintained all night, without dissolving calcium in bones, thus preventing bone loss and osteoporosis.

(2) Milk is not suitable for raw drinking, just heat it to the temperature. When milk is at 100℃, lactose begins to coke, which decomposes to produce lactic acid and formic acid, and its nutritional value decreases. When milk is cooked for a long time, its color turns brown, its fat and flavor decrease, protein degenerates and precipitates, and vitamins are lost. Milk contains rotavirus antibodies that can prevent infantile diarrhea, and it has also been destroyed.

(3) Don't add sugar after the milk is boiled a little cold, because lysine and fructose in milk form fructose lysine at high temperature, which is harmful to human body. Sugar is acidic, and calcium in milk is alkaline. The combination of the two will lead to a large loss of calcium.

(4) It is not advisable to drink milk on an empty stomach. On an empty stomach, the body is hungry and needs energy. When drinking milk at this time, carbohydrates turn into heat energy, and the body will consume protein. It stays in the stomach for a short time and is excreted into the intestine quickly, which is not conducive to digestion and absorption.

(5) Milk should not be eaten with foods containing tannic acid and oxalic acid, such as strong tea, grapefruit, lemon, bayberry, pomegranate, water bamboo, spinach, etc. Because oxalic acid and tannic acid will precipitate with protein, it is not easy to digest and absorb, which destroys nutrition.
