I'm extremely sensitive to glutamate in any form, but especially the MSG and gluten in grains. It doesn't cause stomach upset like it does for celiacs, but mental ones. The anxiety just increases dramatically on days where I don't make my own food, but eat other places. I've also found that glutamate is in absolutely every processed/packaged food in the grocery store. They hide it under flavour, natural flavour and hydrolized protein powder to name but a few......

Demi, this is a really good site about glutamate and other exitorary stuff.
