<<Disclaimer: Verify this information before applying it to your situation.>> I had just about a half dozen responses to my inquiry regarding Hidden Valley Ranch Dressing. Apparently it is the Modified Food Starch that is the culprit. Two people said they had checked with the company very recently and they would not recommend that the product be used by Celiacs because they cannot guarantee that it is GF. It may contain gluten. One person said they use it all the time and never have had a reaction. RC * All posts for product information must include the applicable country *
