<<Disclaimer: Verify this information before applying it to your situation.>> The following response was received from Kay at Panera Bread when questioned about the source of their modified food starch and natural flavors. Use caution when reviewing their website.... "According to our Nutrition Department, the source of the modified food starch in our soups is corn. However, we cannot give a blanket statement regarding food starch and natural flavors in our other menu categories. If there are specific questions about food starch and flavors in salads or beverages, for example, that are not included on our gluten-free list, they will need to be investigated individually. Hope this info helps. Kay" * Please include your location in all posts about products *
