I have experienced it first hand many times and it can be attributed to nothing else but MSG because the heart fluttering only happens when I eat Chinese food at restaurants or packaged food that is loaded with it. It happened every time or used to since I am now meticulous about what I eat. For years I didn't know what his was and even wound up in the hospital over it once.
Isolating Glutamatic acid and eating it in large amounts when it is NOT an essential amino acid, which means that the body produces what is needed and we don’t need to make it up in our diet is the problem and man people are sensitive to that. Why else would people suffer "Chinese Restaurant Syndrome" all over the world?
Saying "Chinese restaurant syndrome is a HOAX" demonstrates nothing mr know it all...
