I'd probably think the same, but a girl I work with was diagnosed with Celiac disease about 2 years ago. What a nightmare, and complete lifestyle change for her. This girl used to love beer, chicken wings etc, and she was in good shape, and now
. Basically if she goes out for lunch or whatever she has to order salad and use her own dressing. Some places offer gluten free menus, but usually the restaurant cannot gaurantee it will not touch other gluten laden foods, so she doesn't trust their foods.
Think of all the foods you love now, and, for me beer, and then think if you were never allowed to have them ever again, or you will get violently sick.
That's her story though and I think a lot of it is a fad, but I know she is completely happy for more gluten free options, as it is opening up more foods etc for her.
