I must admit Seattle that is something I have looked at on and off over the years. For a long while i suspected Mono-Sodium-Glutamat (Natrium Glutamat) and other food additives like sulphites were my problem - I have had "palps" for as long as I can recall and Im 35. Ive been off gluten for 7 years and I avoid processed, junk food so I am quite careful. But you could indeed be right and I may have to be stricter much as I dont want to!
