I too am aware of the glutamate sensitivity issue. I was first diagnosed with glutamate sensitivity and have battled that for many years - it got incredibly worse after a tooth chipped. My ND thought I had leaky gut which was complicating the glutamate stuff - now 8 months later we know mercury is the culprit. It wasn't were my doctors first went but when we tried hair analysis to eliminate the possibility - everyone was surprised by the results. I have had to be very careful how I cook my meat and I have avoided high glutamate foods - tomatoes, walnuts etc. I am slowly able to handle more glutamate but it is very slow. I hope my blood brain barrier will heal after the mercury is out.

Do tell what your experience is!! I am very interested.
