My family is Chinese. I love the traditional cooking AND American-style "Chinese" food. I have never had problems with the MSG in these, but I have had headaches after downing too much brewer's yeast and a broth made with a philipinno soup packet one time. Do you know what both of these have in common? It's Glutamate, which is an excitotoxin in excess amounts. Too much of that stuff absolutely will hurt your head.
