Yogurt should not be drunk on an empty stomach. When people are on an empty stomach, the pH value of gastric juice is less than 2, while lactic acid bacteria in yogurt can only grow, reproduce and play a role in a slightly acidic environment with a pH value lower than 5.4. The strong acid environment with pH less than 2 is not conducive to the survival of lactic acid bacteria. Yogurt should not be taken with erythromycin, chloramphenicol, sulfonamides, cephalosporins and other antibiotics at the same time (such as taking yogurt as water). These drugs can kill lactic acid bacteria. Yogurt is forbidden to be heated. The higher the temperature, the greater the loss of nutrition and lactic acid bacteria. For people with hyperacidity, yogurt should be eaten with other foods. Patients taking antibiotics (drink yogurt after 0.5 ~ 1 hour). Eating yogurt must not be matched with high-fat, processed meat such as sausages and bacon. Because nitrate, that is, nitrous acid, is added to the processed meat, it will form nitrosamine with the amine of yogurt, which is a carcinogen, so try not to eat yogurt with barbecue.

The best time to drink yogurt:

Generally speaking, it is best to drink yogurt between 30 minutes and 2 hours after meals. Under normal circumstances, the PH value of gastric juice is between 1-3. 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 and be 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 most conducive to the absorption of nutrients. In addition, if you drink yogurt on an empty stomach, it is easy to stimulate gastrointestinal emptying, and the nutrients in yogurt are discharged before they can be fully digested and absorbed; Drinking after meals can reduce irritation and make yogurt 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 point of calcium supplementation, drinking yogurt at night is more beneficial. Because the blood calcium content of human body is the lowest in the evening to the early morning 12, which is beneficial to the absorption of calcium in food. At the same time, there are few factors that affect the calcium absorption of human body during this period.
