I noticed about a year and a half ago that I had a real problem with MSG. I don’t eat sushi very often but I remember one particular time I decided to load up on soy sauce. Later that day I had a pounding headache, the worst upset stomach, and it was difficult to breath.
I did some research on MSG and found that people who have OCD also have a small increase in the neurotransmitter “Glutamate”. (Read this article for a study done with OCD patients: http://img2.tapuz.co.il/forums/1_143264754.pdf )
I’ll have to find the citation but I remember another study talking about the role of Glutamate and the frontal lobe (see my first post).
Anyone else have similar problems with MSG? (Or MSG and OCD?)
Here is a picture of the structure of the neurotransmitter Glutamate:
