I feel for you. I am horribly allergic to msg and can feel it in the second it enters my mouth if I make a mistake. I have to avoid so many prepared foods. People are shocked to hear that it is in nearly every cracker and chip, and in EVERY SINGLE PREPARED SOUP period unless you are in a very serious gourmet restaurant who makes their own chicken broth. There is no chicken broth purchasable that does not contain added msg.
However, making your own is easy. After roasting a chicken and carving, throw the carcass into the crockpot with a little vinegar and veggies (onions, leeks, carrots,,etc) and a ton of water and the next day you have plenty of broth for the freezer.
Sorry I meant to include you in my post 60
