One of the best times to drink milk is in the morning and evening. Drinking milk at breakfast provides sufficient nutritional assurance for a day's vitality; drinking milk at night not only helps you sleep, but also helps your body to absorb its nutrients.

According to the United States and Britain, medical experts found that milk contains two kinds of past people unknown hypnotic substances, one of which is able to promote sleep to serotonin synthesis of tryptophan, due to its role, often only a cup of milk can make people fall asleep; another is similar to the role of sedation of the natural morphine-like substances. Therefore, if you drink milk in the morning, it will inevitably inhibit the human cerebral cortex, affecting the daytime work and study. In addition, drinking milk in the morning is not conducive to digestion and absorption, this is because the milk protein through the stomach and the small intestine after the decomposition of amino acids can be absorbed by the body, and the morning fasting state, the stomach, intestinal emptying is very fast, so the milk can not be digested in time to be discharged to the large intestine. In addition, the protein absorbed in the food only on the basis of sufficient calories to form part of the body's tissues, if the calories are insufficient, the absorbed protein will soon become calories and be consumed. Therefore, nutrition experts believe that milk is best consumed in the evening or half an hour before going to bed.

Two, fasting can not:

1, drinking milk on an empty stomach is not good! As water in milk accounted for a greater proportion of milk, drinking more milk on an empty stomach, dilute the gastric juice, is not conducive to the digestion and absorption of food. In addition, fasting intestinal peristalsis is very fast, milk in the stomach and intestines through very quickly, the retention time is very short, and its nutrients are often too late to be absorbed, it is rushed into the large intestine, futile to go through the motions. Therefore, drinking milk on an empty stomach is not in line with nutritional hygiene. Ideal breakfast, should be protein, high-calorie meals, the number of not less than 1/4 of the whole day's food. so it is best to change in the nap or late to drink milk before bed, can be removed from the disadvantages and benefits, better play its role. If you have been used to drinking milk at breakfast, you must also eat a little other food before drinking milk, so that the milk in the stomach and intestines to stay some more time. If you want to drink a bottle of milk for breakfast, you can eat 50 grams of rice or pasta, plus an egg and a little soy sauce, dried tofu, and then drink milk, so that the milk in the stomach and other food mix, in the stomach and intestines to stay longer, is conducive to its nutrients digestion and absorption. As the food provides enough calories, digestion and absorption and slower and sufficient, so that the blood sugar continues to be high level, the morning will be energetic.

Milk can be heated, but do not boil. Because after boiling, some vitamins will be destroyed, and calcium in milk will form calcium phosphate precipitation, affecting the nutrients absorbed by the body. Cooking milk also has some learning, most people will be sugar into the milk and then add fire with cooking, which will make the milk lysine amino acids and sugar react at high temperatures, generating fructosyl lysine, this substance will not be digested and absorbed by the human body, but on the contrary, harmful to human health, so the milk should be boiled milk is not hot and then add sugar.

2, experts remind the public should not drink milk on an empty stomach. According to reports, many people drink milk early in the morning, that will be able to fully absorb the nutrients. In fact, drinking milk on an empty stomach will soon be discharged into the large intestine through the stomach and small intestine, as a result of a variety of nutrients can not be digested and absorbed in time to be discharged from the body. The correct method should be to eat some food before drinking milk. Too much stomach acid leads to protein denaturation and precipitation, nutrients are not easy to be absorbed by the stomach and intestines, leading to serious indigestion and diarrhea. Therefore, it should be accompanied by some bread, cookies, snacks and milk with food. It can be seen, should not drink milk on an empty stomach for the following main reasons: first, it is easy to lead to diarrhea; second, the efficiency of absorption is not high. This is because the time it takes to pass through the gastrointestinal tract is too fast. Try to put the milk at the end of a meal of all the food before drinking, so as to facilitate absorption and improve tolerance.

Three, before bedtime can be: drink milk before bedtime is conducive to the body's absorption of calcium utilization. Dinner intake of calcium, most of the body before bedtime absorption and utilization. After sleeping, especially after midnight, the level of calcium in the blood will gradually decrease, the decline in blood calcium, promote the parathyroid gland hypersecretion, hormone action in bone tissue, bone tissue, part of the calcium salts, dissolved into the blood to maintain a stable balance of blood calcium. This dissolving effect is the body's self-regulation function, over time, will become one of the causes of osteoporosis. Drinking milk before going to bed at night, the calcium in milk can be slowly absorbed by the blood, the whole night blood calcium have been supplemented to maintain the balance, do not have to dissolve the calcium in the bone, to prevent bone loss, osteoporosis, so drink milk before going to bed is good.

Four, control the total: to get the benefits of drinking milk to lose weight, we have to control the total energy, drink more milk at the same time to reduce the intake of other foods accordingly, especially those with low nutritional value and high caloric value of food, such as sweet drinks, desserts, sweets, puffed food, cold noodles, cold skin and so on and high-fat food, reduce the dinner staple food, in order to ensure that the balance of the total. If you drink milk between meals or before meals, it can help your body to reduce your appetite, and you will not eat too much for lunch and dinner. If the body is overweight or obese, it is not advocated to drink milk after meals or before going to bed.

Fifth: other misconceptions about drinking milk. Improper food matching: milk should not be eaten with food containing tannins, such as strong tea, persimmons, etc., these foods are easy to react with the milk lumps into a ball, affecting digestion.

Favorite highly processed milk. Highly processed milk, its nutritional value is not necessarily better than fresh milk. This is because after many times of processing, most of the milk added trace elements or inorganic salts, but these components are not everyone needs to supplement, so it is not necessarily suitable for everyone.
