Yogurt and yogurt drinks are not the same thing. Professor Zhang Jiazhi from Beijing Food Research Institute said that the nutritional value of yogurt and yogurt drinks is very different. Professor Zhang said that yogurt is made of high-quality milk fermented by lactic acid bacteria, which belongs to the category of milk in essence; Yogurt drink, that is, lactic acid drink, is just a drink, not milk anymore. Therefore, the nutritional content of the two is very different, and the nutrition of yogurt drink is only 1/3 of yogurt.
