Input:
Due to my frequent migraines, I am checking everything I eat and I
was disappointed to realize that this has quite a few ingredients (containing free-glutamic acid (MSG)) that
are contributing to my migraine.  I have purchased and eaten quite a bit of Mountain Food products.  With my new diet of
avoiding foods with migraine triggers, I have gone from several migraines a week to nearly migraine free.
