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 3 minutes and 2 hours after meals has the best effect. Under normal conditions, the PH value of gastric juice is between 1 and 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 12 o'clock in the evening to early morning is the time when 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 for the next meal.
