Yes! Generally don't drink yogurt on an empty stomach. Because the pH value suitable for the growth of lactic acid bacteria is below 5.4, the acidic pH value of human gastric juice is below 2 on an empty stomach, and the pH value can rise to 3.5 when gastric juice is diluted after meals. Therefore, if you drink yogurt on an empty stomach, lactic acid bacteria will be easily killed and the health care function will be weakened, so it is generally better to drink it 2 hours after meals. Also try not to drink too cold, for fear that the stomach sometimes can't accept it.
