Milk is very high in nutritional value, containing the body's much-needed proteins and minerals amino acids, vitamins, and the most easily absorbed by the body, often drink milk can make people's bodies strong, the required nutrient balance. The best time to drink milk: breakfast calorie supply accounted for 30% of the total calorie supply, a glass of milk for breakfast is better; can also be in the afternoon around 4 o'clock, 1 - 2 hours before dinner, as a drink to drink, supplemented by the work hard to bring the nutritional needs of the evening before going to bed to drink a glass of milk, to help you sleep. But be careful, do not drink on an empty stomach, can not drink with tea, should not be heated with copper, do not boil and steam for a long time, do not drink ice milk. The best time to drink milk The time to drink milk on the human body to digest and attract the nutrients in the milk also has a certain impact, children's time to drink milk is determined by the age of the number of times a day, time and the amount of milk, adults drink milk to pay attention to the time to drink milk. Some adults have the habit of drinking milk in the morning, this method is not scientific, the reason is that after a night's sleep and rest, the human stomach has long been emptied, ready to eat and digest food, when the stomach is emptied very quickly, and the milk is fluid milk, the stomach is discharged more quickly. Drinking milk on an empty stomach, in the stomach has not been fully digested and absorbed into the intestines caused by the loss of nutrients. Milk is rich in high-quality proteins, the main role of these proteins is to constitute the body's new tissues, but also on the original tissue repair, if you drink milk on an empty stomach not only milk from the stomach quickly discharged, but also the above valuable proteins will be broken down by the human body as calories to be consumed, which can not play a full role in the protein should be, very unfortunate. Milk protein in the human stomach by pepsin and small intestine digestion and decomposition into a variety of amino acids to be absorbed and utilized in the small intestine, drinking milk on an empty stomach fast gastric emptying so that some proteins are not broken down into amino acids, some amino acids in the small intestine did not have time to be absorbed into the large intestine, in the colon, these proteins and amino acids are broken down into corruption of the human body into a harmful substance, so that the valuable proteins are not fully to the The valuable proteins are not fully utilized as they should be. It also increases the burden on the human body. To change this situation, first of all, do not drink milk on an empty stomach in the morning, but instead in the morning after breakfast 1-2 hours after drinking milk, food in the stomach to prevent the shortcomings of drinking milk on an empty stomach; second is to drink milk before eating some food containing more starch, such as steamed bread, etc.; third is to drink milk in the morning to eat some buns, rice, bread, cookies, snacks and other starch-containing foods, which will make the milk in the stomach to stay for a longer period of time, milk and gastric juice can fully undergo enzymatic digestion. With the gastric juice can be fully enzymatic action, so that the protein can be well digested and absorbed. Milk has a hypnotic and sedative effect, the morning is people's energy to study and work time, after drinking milk to make people feel drowsy, but on the learning and work is not good, so it is best not to drink milk on an empty stomach in the morning. What is the best time to drink milk? It is best to drink milk at night, because milk contains a biochemical that can make people tired and sleepy L tryptophan, as well as trace morphine-like substances, these substances have a certain sedative-hypnotic effect, especially L tryptophan, which is the brain synthesis of hydroxycolors of the main raw materials, five hydroxytryptophan on the brain sleep plays a key role in the brain, which can make the brain thinking activity is temporarily inhibited, so that people want to sleep, and without any side effects! The milk sticks to the stomach wall and is absorbed well, and the calcium in the milk can also remove tension, so it is more beneficial to the elderly sleep, so drinking milk at night is good for people's rest and sleep. Drinking milk before going to bed is conducive to the body's absorption and utilization of calcium. Most of the calcium ingested at dinner is absorbed and utilized by the body before bedtime. After sleeping, especially after zero o'clock in the evening, 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, so that part of the calcium salt in the bone tissue, dissolved into the blood, in order 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 the milk can be slowly absorbed by the blood, the whole night blood calcium has 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 good. *8 kinds of people should not drink milk 1. often exposed to lead: milk lactose can promote the absorption of lead in the human body accumulation, easily cause lead poisoning, therefore, often exposed to lead should not drink milk, you can change to drink sour milk, because sour milk lactose is very little, more than lactic acid. 2. Lactose intolerant people: some people's body seriously lacks lactase, so the lactose in milk ingested into the body can not be converted into galactose and glucose for absorption and utilization in the small intestine, but directly into the large intestine, so that the osmotic pressure of the intestinal lumen is elevated, so that the mucous membrane of the large intestine to inhale a large amount of water, in addition, lactose in the intestines by bacterial fermentation can produce lactic acid, so that the intestinal PH value drops below 6, thus stimulating the large intestine, resulting in bloating, abdominal pain, gas and abdominal pain. Abdominal pain, abdominal pain, gas and diarrhea and other symptoms. 3. Milk allergy: some people drink milk after abdominal pain, diarrhea and other symptoms, individual severe allergies, and even rhinitis, asthma or urticaria. 4. Patients with reflux esophagitis: milk has the effect of lowering the pressure of the lower esophageal sphincter, thereby increasing the reflux of gastric or intestinal juices, aggravating esophagitis. 5. Patients after laparotomy and gastrectomy: the lactase in the patient's body will be affected and reduced, after drinking milk, lactose can not be broken down in the body will ferment, producing water, lactic acid and a lot of carbon dioxide, so that the patient's abdominal distension. During laparotomy, the intestinal tube is exposed to air for a long time, and the mesentery is pulled, which delays the recovery of peristalsis after surgery, and the gas produced in the intestinal cavity due to swallowing or fermentation cannot be discharged in a timely manner, which aggravates abdominal distension, and abdominal pain, increased intra-abdominal pressure, and even distension of suture cracks and abdominal wall incision splitting can occur. After gastrectomy, due to the small gastric pouch left after surgery, milk containing lactose will quickly rush into the small intestine, so that the original already insufficient or lack of lactase, more insufficient or lack of. 6. Patients with irritable bowel syndrome: This is a common functional intestinal disease characterized by malfunction of the intestinal muscle motor function and intestinal mucosal secretion of mucus in response to stimuli, without any intestinal structural lesions, the symptoms are mainly related to psychiatric factors, food allergies, including allergies to milk and its products. 7. Patients with cholecystitis and pancreatitis: to digest the fat in milk, bile and pancreatic enzymes must be supplied, and milk aggravates the burden on the gallbladder and pancreas, which results in the exacerbation of symptoms. 8. usually have bloating, fart, abdominal pain and diarrhea and other symptoms: these symptoms are not caused by milk, but after drinking milk will make these symptoms worse. * morning children do not drink milk on an empty stomach Milk is indeed a rich protein, fat and other nutrients in the food, the growth and development of children have a great help, but many parents let children drink milk on an empty stomach in the morning, some children only drink milk to go to school, which is not in line with the nutritional requirements of the unscientific. Milk in the water accounted for a larger proportion of a bottle of milk 230 ml, water accounted for 87%, solid matter accounted for 13%, including protein, sugar, fat and minerals, vitamins, etc., the total calorie production of 666.5 kilojoules. Generally speaking, breakfast should account for 20-30% of the total calories of the day. 7-year-old children need a total of 7560 kilojoules of calories a day, breakfast should be obtained 1512-2258 kilojoules, and a bottle of milk can only provide one-third of the calories; furthermore, the 7-year-old children need 60 grams of protein per day, breakfast at least 15-20 grams, and a bottle of milk provides only 8.05 grams. Therefore, only one bottle of milk for breakfast is not in line with the nutritional requirements of children. As water accounts for a larger proportion of milk, drinking more milk on an empty stomach dilutes the gastric juice, which is not conducive to the digestion and absorption of food. In addition, fasting intestinal peristalsis is very fast, milk quickly in the stomach and intestines through, 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. The ideal breakfast should be a high-protein, high-calorie meal, the number of not less than one-fourth of the whole day's food. 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 foods mixed, in the stomach to stay longer, conducive to the digestion and absorption of nutrients. This is very good for the child's health. Milk covers six nutrients, which are needed for the growth and development of the body's newborn organs; in fact, if you do not drink a glass (240c.c) of milk every day, you will be insufficient in calcium intake from time to time. You can't be unaware of the nutritional value of milk, which covers six major groups of nutrients and is rich in foods that contain: *Protein - the basic component that makes up hair, skin, nails, muscles, organs, cells, nerves, bones, brain tissue, hormones, antibodies and determines genes, and it is the nutrient that is most in demand. Fats - are essential for the transportation of vitamins a, d, e, and k, and provide various essential fatty acids for the body. *Carbohydrates - Lactose is the most important source of energy and promotes the growth of probiotics in the intestinal tract. *Water - 88% of milk is water, which is essential for chemical reactions and organ interactions in the body. Vitamins b2, b6, b12, and nicotinic acid-help the body utilize nutrients, promote metabolism, and maintain the health of organs and tissues. Vitamin A - has antioxidant properties, protects the body from bacterial infections, and maintains normal vision and healthy skin. *Vitamin D - helps in the absorption of calcium, which is essential for bones and teeth. *Calcium - 99% of calcium is found in the bones of the human body and is required for muscle contraction, heart rhythm, blood clotting, enzyme production and nerve conduction. Potassium, sodium, chloride and magnesium*** work together to maintain endocrine balance and keep the body healthy and tissues functioning properly. A small glass of milk, containing high nutritional value of the ingredients can be quite a lot, in the 15 essential minerals, calcium, phosphorus, magnesium, potassium, chlorine, sodium, the need for a large amount of six, the content of rich iron, although not much, but very well absorbed. Obese people who are worried about consuming too much fat, drinking low-fat milk is the most suitable. The human body's activity energy and permanent health depends on the diet, milk is a nutritious food in the best, so you must develop a good habit of drinking a glass of milk every day.
