There's a lot of Asian pride in telling me it's not msg, and doing studies to prove it's not msg. (Asian pride as described by Asian pride experts of that ethnicity).
However, the horrible fact remains that for some people MSG is proving to be the cause of reactions. The usual source is restaurants using MSG, but just to clarify the matter we find out the hard way when friends get too happy with MSG.
As much as I want to believe in rigorous science I still have to tell you that you're not considering the actual sufferers. It's a reaction akin to getting punched, and I definitely know about it.
It wounds the pride of the occasional restaurant that doesn't really want people to walk out because of a medical problem. I'm sorry about that. I'll look into possible solutions. It's my fault for really enjoying Asia and Asian food.
