I remember reading your original post about Mono-Sodium-Glutamat (Natrium Glutamat) detection using a pendulum and was happy for you as I have been a dowser for many years and use my pendulum in many ways. I never understood why you deleted so many of your subsequent posts.
I just ran across some of your similar posts on the http://www.msgmyth.com
but didn't know how I could contact you through that forum.
I just ordered the following gizmo which works on the principle of applied kinisiology (using muscle strength testing as a gauge for whether or not something is good or bad for you). I thought it might come in handy when it just isn't appropriate to pull out my pendulum.
Here is a link where you can find more information.
