Late to this thread but here’s my take – a few years ago, my dear babysitter’s son was diagnosed with Celiac Disease. He was about 10. In researching Celiac Disease, out of concern for him and to give her some information, I found out that gluten is in many products that we’d not realize: cough medicines, barbecue sauce and other condiments, processed meats, you name it, the list goes on. People who have tried gluten free diets (like Elizabeth Hasselhoff from The View) say it makes them feel a whole lot better. So I say don’t knock it till you’ve tried it.
In researching for my babysitter, I found some gluten free cooking and baking sites. They say that when you bake gluten free, using flours made from other things other than wheat, you can actually add or modify the flavors of what you bake because wheat flour is relatively bland. You can use flours made from things like almonds, hazelnuts, stuff like that, which alters and adds flavor. I’ve never tried it but it sounds interesting.
Again, like someone said above, let’s not hate on the people who try something and find success with it.
