<<Disclaimer: Verify this information before applying it to your situation.>> I called the 800 # and they told me that all of their dressings including fat-free are gluten free. I read all the bottles on the shelf and lo and behold=vineger white and cider. But not on every bottle? They don't seem to agree when you call. I had some and my stomach is bothering me, so what does that tell you and I am not super sensitive. Would someone out there have a response or check and see what they say to you? 1-800338-8831 I am getting not place fast. Just checked again and the french f/f states distilled and cider, which they say is made from corn. maybe it's just the entire vinegar product that bothers me because I do have a yeast allergy. Thanks in advance. Rosalie
