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. 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.

1. Lactic acid contained in yogurt helps people's gastrointestinal peristalsis at night, so drinking it at night will not only lead to indigestion, but also help prevent constipation. Drink yogurt about two hours after dinner, and avoid drinking yogurt on an empty stomach. Because lactic acid bacteria in yogurt are easily killed by gastric acid on an empty stomach, the health care function of yogurt will be weakened.
