Yogurt 1. Yogurt should not be consumed on an empty stomach. Because if you drink yogurt on an empty stomach, the lactic acid bacteria will be easily killed by gastric acid, and its nutritional value and health care effects will be greatly reduced. 2. Yogurt should not be heated and consumed. Because once yogurt is steamed and heated, a large number of active lactic acid bacteria contained in yogurt will be killed, the unique taste and texture of yogurt will disappear, and its nutritional value and health care functions will also be greatly reduced. 3. After the baby drinks yogurt, parents must urge them to rinse their mouth quickly, otherwise dental caries will easily occur. Soy milk 1. Compared with fresh milk and yogurt, which are not suitable for being thoroughly cooked and heated, soy milk is just the opposite. Because the trypsin inhibitor contained in fresh soy milk needs to be boiled for 3 to 5 minutes to decompose, soy milk must be cooked thoroughly before it is suitable for drinking. 2. As the weather gets cooler, some parents may heat soy milk and put it in a thermos bottle for their children to take to school and drink it during recess or lunch break. However, this approach is not advisable. Because the soluble saponins contained in soy milk can dissolve the scale in the thermos bottle, it will harm your health
