<<Disclaimer: Verify this information before applying it to your situation.>> OK, I give up. I've been trying to find out if Burger King vanilla shakes are GF. I've searched the archives and only found info on fries. I called a number for BK I found in the archives, and she read off an ingredient list including vanilla, mono and diglycerides and caramel color, all of which are questionable. She couldn't tell me whether those questionables are derived from the "bad" grains or not. I drank one Saturday after someone was kind enough to buy it for me. I know - wrong thing to do. Three hours later I was in the bathroom and haven't felt right since. I haven't knowingly ingested any gluten for almost 5 months now, so I don't know how I react. Perhaps this was just coincidence, or some level of lactose intolerance, but I'd really like to know. Thanks! Elizabeth
