<<Disclaimer: Verify this information before applying it to your situation.>> Wow! What a response to my question about whether gf mixes cause any problems with other celiacs. Overwhelmingly, the answers were YES! Some speculated that certain ingredients such as xantham gum could be causing the symptoms. Others weren't sure why it happened when they ate something that came from a gf mix, but felt better (as I do) when eating fresh, whole foods. They chose not to use packaged items. Thanks again for all of the wonderful e-mails! Christie in TX
