MSG and schizophrenia

“One does not typically think of MSG as a trigger for psychiatric conditions. However, there is a clear link of glutamic acid to Schizophrenia, leading to the present development of a glutamate blocker for treatment of Schizophrenia.”

I found that I cannot tolerate yeast food and yeast extract containing food,
it feels like a headache that gives me intense pleasure and then intense pain.

Does anyone have a reaction to any of these ingredients that contain glutamic acid?
