<<Disclaimer: Verify this information before applying it to your situation.>> Hi all! I just returned from the Gluten Intolerance Group's annual conference in Bellevue, WA and the same question about distilled vinegar was asked a pharmacist who was giving a presentation on GF prescriptions. The GIG's director answered for him. She said it indeed sounds impossible, but it is on their list as unsafe because so many members have reacted badly to it and their position is that they cannot recommend it's use when they know it appears to present all the CD problems a glutamine containing substance does.
