Im in the same boat re: the msg.. its in alot of your frozen foods, salad dressings, only salad dressings I have found that dont have it is.. the Kraft three cheese dressing.also plain italian.. I think it is..
Beware of Chinese food also. unless you can request it be made without it.
Thats how I found out I was super sensitive to it. I found out that I was by eating some chinese food at our local Mall.
Most Campbells soups have it. you can read labels ( it is a pain to do this but.. sure saves alot of headaches and such with being sensitive to it..) its also in some deli sandwich meats.. and like Polish sausage.. i have found at Wegmans their brand doesnt have it in theirs..
Good Luck .. just keep reading ingredients.. Thats what I do..
take care
