So Delicious Coconut Milk ice cream is safe. It doesn't contain any gluten. It is high in fat content, but good fat is the same as bad fat when it comes to your intestinal tract. It can act as a laxative and cause cramping. If I eat too much of it, that's exactly what happens. Gluten like reaction minus the gluten. You don't have to be a rocket scientist to figure this out. I am also in research so have that analytical mind but never let that get in the way of common sense. It is entirely possible to over think things to the point of obsession. This is what I see here.
For newbies, it's this simple....if you stick with certified gluten-free products and stay away from shared facilities, unless they have a good track record for keeping things separate and clean, you should be fine. If you do react to a new food, it probably is not going to be from gluten but from one of many other reasons mentioned already. You may have to heal a long while before you get to the point where you can eat without getting sick a couple of times a week. This is normal. Continuing problems should be addressed with a doctor you trust. There may be an underlying problem, common to Celiacs. Above all, relax and don't live in fear of minute amounts of gluten out there, otherwise, you'll end up like some of the posters to this forum....overly obsessive about food and life.
