Is monosodium glutamate harmful to human health?

Monosodium glutamate is safe, but it should not be added in excess during cooking, and should be used in moderation. After all, monosodium glutamate is just a flavoring agent. At the same time, in the process of cooking, we should pay attention to the temperature (70-80℃ is appropriate) and time (it is best to put the soup in before it is cooked thoroughly). So "MSG is good, don't put more."
