I have a coeliac in the family. They get free gluten free flour at the pharmacy. I don't know what it's like in the States, though. Also, you can pretty much strike any fast food from your diet. Apart from that, there are loads of gluten free products available, nowadays. You should probably contact your local coeliac patient organization, I'm sure they can help you even if you don't suffer from the same thing.
But Morty, shouldn't your parents know best?
