Tip: Although the flora added in yogurt has many names, their functions are similar, which is mainly beneficial to human digestion and absorption. However, because the flora needs to be refrigerated at low temperature to survive, some of them will die during the transportation and sale of yogurt, so the number of live flora marked on the package is inconsistent with the number when it is sold and drunk. In addition, if you take too much, it will destroy the balance of flora in the human intestine, but it will reduce the digestive function.
