<<Disclaimer: Verify this information before applying it to your situation.>> This morning I emailed the makers of White Wave as someone on this list requested. This is their response. >Thank you for your interest in White Wave. Our Vanilla and Chocolate Silk >does contain a wheat and/or corn based vanilla extract. Our Plain Silk >contains a wheat and/or corn based vanilla extract in the natural flavoring. >The gluten in these products does exist but it is virtually undetectable. You >should contact your health care professional to discuss whether or not you >may consume vanilla extract, since gluten sensitivity can vary from person to >person. I hope this information helps you. Best regards from TofuTown.
