Drinking yogurt every day has become a dietary habit of many people. Because yogurt does not need to be heated, it is convenient to drink, so some people drink it in large quantities, and some people eat it when they are hungry. But from a nutritional point of view, drinking yogurt also pays attention to time, and drinking too much will bring negative effects to the body. Drinking after meals is beneficial to absorb nutrition. Generally speaking, drinking yogurt between 30 minutes and 2 hours after meals has the best effect. Under normal conditions, the PH value of gastric juice is between1-3; On an empty stomach, the gastric juice is acidic, and the PH value is below 2, which is not suitable for the growth of active lactic acid bacteria in yogurt. Only when the PH value of the stomach is relatively high can the lactic acid bacteria in yogurt grow fully, which is beneficial to health. About two hours after a meal, people's gastric juice is diluted, and the PH value will rise to 3-5. At this time, drinking yogurt is the most beneficial to absorb the nutrients. In addition, if you drink yogurt on an empty stomach, it will easily stimulate gastrointestinal emptying, and the nutrients in yogurt will be discharged before it can be completely digested and absorbed; Drinking after meals can reduce irritation and let yogurt be slowly absorbed in the stomach. Drinking yogurt with the best calcium supplement effect at night is a good source of calcium in food. From the perspective of calcium supplement, drinking yogurt at night has more benefits. Because at night 12 to the early morning, the blood calcium content of human body is the lowest, which is beneficial to the absorption of calcium in food. At the same time, there are fewer factors affecting calcium absorption in human body during this period. Although milk also contains high calcium, compared with it, lactic acid contained in yogurt can combine with calcium to promote calcium absorption. However, when you drink yogurt at night, you must remember that some strains and acidic substances in yogurt have certain damage to your teeth, and you should brush your teeth in time after drinking. It can promote gastrointestinal peristalsis and relieve constipation. Many women like to drink yogurt. One of the important reasons is that no matter how much they drink, they will not get fat. Yogurt does have a certain weight loss effect, mainly because it contains a large number of active lactic acid bacteria, which can effectively regulate the balance of flora in the body, promote gastrointestinal peristalsis, and thus relieve constipation. There is a certain relationship between long-term constipation and weight gain. Then yogurt has a strong sense of fullness, and drinking a cup when you are slightly hungry can effectively alleviate your urgent appetite, thus reducing the amount of meals in the next meal. However, yogurt doesn't get fat if you drink it. It also contains a certain amount of calories. If you eat more on the basis of the original diet, it will also cause weight gain. The best way is to choose yogurt marked with defatted and low-calorie words. Although their taste is not as rich and mellow as full-fat yogurt, their calories are low, which will not make them accumulate in the body quickly and get fat. In addition, yogurt is not suitable for all ages. Patients after gastrointestinal surgery, patients with diarrhea and infants under 1 year-old should not drink yogurt. Even healthy adults should not drink too much, otherwise it will easily lead to hyperacidity, affect the secretion of gastric mucosa and digestive enzymes, reduce appetite and destroy the electrolyte balance in the human body. Generally speaking, it is more appropriate to drink two cups a day, each at around125g. Drinking yogurt often can not only promote gastrointestinal digestion, but also be good for skin and liver. But there is no effect of losing weight. It seems that hangover is very good. Yogurt contains lactic acid bacteria, which can help digestion. Yogurt is a long-lived drink. According to the results of the earliest research on yogurt by Nobel Prize winner and Russian food expert Mechnikov (1845- 19 16), yogurt contains a growth active factor, which can enhance the immune function of the body, and is beneficial to health, disease resistance and anti-aging. There are many longevity places in the world, and residents have the habit of drinking yogurt for a long time. The reasons why yogurt is beneficial to human health and longevity may be:1.Yogurt can enhance human immune function; 2. Reduce the level of serum cholesterol. Experiments have proved that even without any drugs. After drinking about 24 grams of yogurt per meal, cholesterol can be reduced after one week. 3. Regular consumption of yogurt can promote intestinal movement, shorten the transit time of food from mouth to anus, soften the contents of glycolysis colon, increase fecal excretion, prevent constipation, and help prevent colon cancer. Therefore, yogurt is known as longevity food abroad. Who should drink yogurt best? Most of the sugar contained in milk is lactose. However, due to the lack of lactase in digestive juice of some adults, it affects the digestion, absorption and utilization of lactose, causing stomach discomfort and even diarrhea after drinking milk, which is called lactose intolerance. This is also the reason why many people don't drink milk. At this time, you can choose yogurt instead of milk without worrying about lactose. Yogurt contains lactic acid bacteria; Lactose in milk can be converted into lactic acid by lactobacillus fermentation, and lactose intolerant people will not have diarrhea symptoms when drinking yogurt, which just solves the problems that some people may have when drinking milk. However, it is worth noting that many yogurt drinks (instead of yogurt) are made of milk, water and sour agents. Such products will also contain lactic acid, which can also cause lactose intolerance. 1, patients with arteriosclerosis and hypertension Some nutritionists have found that yogurt contains a milk factor, which can reduce serum cholesterol in human body. Calcium lactate in yogurt is easily absorbed by human body. Some people have done experiments, drinking 720 grams of yogurt every day can significantly reduce serum cholesterol after one week. 2. During the fermentation process, Lactobacillus bifidus in the yogurt of cancer patients produces acetic acid, lactic acid and formic acid, which can inhibit nitrate-reducing bacteria, block the formation of carcinogenic nitrosamines, and play a role in preventing cancer. Some countries with developed dairy industry in Europe believe that a cup of yogurt a day keeps women from worrying about breast cancer. 3. Lactic acid bacteria in the yogurt of the elderly and infirm patients can decompose lactose in milk to form lactic acid, which makes the intestines tend to be acidic, inhibits spoilage bacteria that grow and reproduce in neutral or alkaline environment, and can also synthesize nutrients such as vitamin B, folic acid and vitamin E, which are rich in protein and vitamin A, which is very beneficial to the elderly and infirm. 4. Antibiotics users control pathogenic bacteria while non-pathogenic bacteria are also suppressed, which may lead to loss of appetite, nausea and vomiting, dizziness, etc., and may lead to another infectious disease. Yogurt contains active Mycobacterium longum, which can make the gastrointestinal flora imbalance regain balance. 5. The yogurt of patients with osteoporosis contains calcium lactate which is easily absorbed by people. This will increase the calcium of patients, which is beneficial to the prevention and treatment of osteoporosis. Drinking yogurt at night is more beneficial. Because from the point of view of calcium supplementation, because people no longer eat calcium-containing food at night, calcium metabolism is still quietly going on during sleep, so it is necessary to eat a proper amount of calcium-rich dairy products before going to bed. Yogurt is a dairy product that many people like to eat. She is nutritious, cool and refreshing, easily digested and absorbed, and eating yogurt often is good for health. Yogurt can prevent constipation and bacterial diarrhea, and also help digestion. Yogurt contains live lactobacillus and lactic acid, which increases the acidity in the intestine and inhibits the reproduction of spoilage bacteria, prevents protein fermentation and reduces gas production in the intestine, thus alleviating symptoms such as fullness, bloating and indigestion. Eating yogurt often can also prevent cardiovascular diseases in the elderly. Yogurt can lower cholesterol, which is a metabolite of human fat. With the increase of age and abnormal metabolism, the cholesterol in plasma will increase, resulting in "hypercholesterolemia". Regular consumption of yogurt can also moisturize skin, improve eyesight, strengthen teeth, strengthen hair and prevent cell aging. Yogurt made by sterilization, inoculation with lactic acid bacteria and fermentation has the functions of nutrition, health care and beauty. The highly active minerals such as calcium, magnesium, manganese and trace elements in yogurt can protect teeth and strengthen bones, while vitamin A, vitamin B, methionine and cystine can improve eyesight and blacken hair. So it is best to drink yogurt at night.
