What a ridiculous attitude. I take it you don't use salt either, then.
Many "additives" are used to enhance flavour all across the world: salt, sugar, pepper, acids (vinegar or lemon juice etc), wine and other alcoholic beverages etc. The list goes on.
MSG is just another on the list.

I have no intention of reviving this old argument, but very few, if any, people are allergic to MSG. No controlled study (and there have been more studies of MSG than any other "additive") has ever identified a single case of MSG allergy. If you want to see what's been said here before, there are over 200 comments here.
