<<Disclaimer: Verify this information before applying it to your situation.>> I recently noticed that Waist Watchers Orange Soda made by Adirondack listed modified food stach as an ingredient. I contacted the Adirondack Corporation and got the following reply: Thank you for your e-mail regarding our Waist Watcher beverages. We are always pleased to hear from our customers and thank you for your patronage. All of our Adirondack and Waist Watcher sodas are gluten-free. We use high fructose corn syrup or sucralose and acesulfame potassium (ace-K) to sweeten our products. Modified food starch and yellow #5 color are also gluten-free. Modified food starch is made from corn and does not contain any wheat or wheat derivatives. I hope we have been able to sufficiently answer your question. If you have any additional questions or comments, please feel free to call us toll-free at 1-800-316-6096. Tony in Kensington
