N.,
I know several people with celiac disease, as well. Yes, many of the foods are very expensive, unfortunately. That said more and more mainstream companies are coming out with gluten-free foods so you may find a little success in your local supermarket. I can't remember if it's certain Post Cereals or General Mills Cereals that are now gluten-free. I would post on the celiac message boards out there, as well. I sympathize with you and your husband. It's quite a life-changing event when you have to go gluten-free.
Are you aware that Bonefish Grill (a chain) and Outback Steakhouse offer gluten-free menus? I've not been to Outback, but I hear they have a wonderful flourless cake there.
Food prices aside, your husband should stick to a gluten-free diet, as the affects of not being on one can be devistating to his autoimmune system and wreak havoc with his overall health. I would continue to ask many questions, as you'll be amazed at how many people are being diagnosed with it now and the variety of products being offered.
There are at least 3 bakeries in a 20 or so mile radius from me that make gluten-free baked goods.
Also, as a post script to Angela's response (I think that's who it was)-- Celiac Disease is hereditary and can skip a generation, so it is wise to have all family members tested, including grandchildren. If the members of your husband's immediate family haven't been tested, they should be to be on the safe side.
Good luck with your continued research.
