A cup of milk before going to bed, someone suitable for someone not suitable.

Milk stomach, calcium, but also to help sleep, these effects have been widely popularized, many people in addition to drinking milk during the day, often at night before going to sleep but also come to a cup of fragrant milk, hoping to let yourself fall asleep as soon as possible. Some milk brands have also taken a look at this market, subdividing different types of breakfast milk and sleeping milk to facilitate people to drink at different times.

Patients with kidney stones do not need to quit milk. "Kidney stones should not drink milk before going to bed." This is currently mentioned more often. The reason is that the vast majority of kidney stones are composed of calcium oxalate components. Excessive intake of animal protein and dairy products can significantly increase urinary calcium and oxalic acid levels and facilitate the formation and recurrence of kidney stones. In the evening, it happens to be the peak period of stone excretion. If this time to drink milk, milk calcium content is high, and after drinking milk 2 to 3 hours, it is the peak of calcium removal through the kidneys, if at this time is in a state of sleep, urine concentration, calcium through the kidney more, easy Stone formation. Chen Junxian disagrees with this statement: "There is no direct connection between milk and kidney stones, at least in the sciences." Increased levels of oxalate or calcium in the blood can cause kidney stones, but human blood calcium increases. Mainly because of osteoporosis, which is caused by increased calcium in bone loss, not because of drinking milk. Patients with kidney stones should eat less foods such as spinach and oxalic acid to reduce the formation of calcium oxalate in the blood and prevent stone formation. Daily drinking water at multiple times every day to ensure the urine volume is about 2500-3000 ml, which is also good for preventing kidney stones.

However, medical experts have cautioned that although drinking milk before going to bed does promote sleep, it is not for everyone. Some patients drink milk before going to bed, not only do not help sleep, but will cause some harm to the body.

Patients with stomach and reflux esophagitis do not drink before going to bed. For some patients, bedtime milk is definitely the number one taboo. Dr. Lu Bin, deputy dean of the Zhejiang Provincial Hospital and chief physician of the Department of Gastroenterology, said that drinking milk before going to bed does not have a bad influence on the average person, but gastric ulcers and reflux esophagitis patients should pay special attention because these patients have gastric acid secretion. Too much, and protein, fat, and sugar in milk can cause gastric acid secretion. Although milk just enters the stomach, it can dilute the concentration of gastric acid, relieve stomach acid and stomach and duodenal ulcers, and relieve upper abdominal discomfort temporarily. But after a while, milk has become a stimulating factor for gastric mucosa, resulting in more gastric acid, which can easily cause stomach damage during nighttime fasting and aggravate symptoms of reflux. Not only milk, but people with different diseases have different taboos on their diet. For example, patients with reflux esophagitis may have delayed gastric emptying and may have flatulence. It is best not to drink carbonated drinks or to eat supper before going to bed. But for some patients with gastric ulcers, especially duodenal ulcers, the opposite is true. Because stomach emptying is particularly fast, if you have an empty stomach before going to bed, you should eat some supper.

Chen Junxian, a gastroenterologist at Tongde Hospital, pointed out that people with diabetes should also try to control before going to bed. "This kind of patient is not to say that it is impossible to drink, but is mainly controlled intake." It is understood that patients with type 2 diabetes are mostly old people, who are accompanied by different degrees of hyperlipidemia, hypertension, fatty liver, etc. Drink milk quickly before absorption, will affect the control of blood lipids and body weight to varying degrees. Therefore, diabetics drink milk best during the day, use low-fat milk, about 200 ml each time. In addition, diabetic patients with retinal complications are advised to drink less milk. Some patients with diabetes and eye diseases are caused by lactase deficiency, while milk contains 5% lactose. From a clinical point of view, lactose can be decomposed into galactose by the action of human lactase. If too much milk is ingested, galactose deposition is easily attached to the lens of the eye, affecting the normal metabolism of the lens and reducing the transparency, can promote and accelerate Occurrence of senile cataract.
