Intolerance, which I have, is very different from the real allergy. That can kill you. People with an intolerance just learn to avoid it as much as possible, but it's really tough for those with the allergy because even if you go out for the day and are assured that your food is gluten free, it could have been cooked in a utensil that once contained gluten.
Personally I wouldn't dream of obtaining foods on prescription, but then I have learnt to cook around it and go without, but I do have the luxury of being able to eat things I shouldn't on rare occasions. My downfall lately has been an absolute craving for toasted teacakes. I told myself I was making them for DS. I ate one every other day - no other gluten at all - and in just over a week was glued to the loo, had awful headaches and the stomach pain kept me up all night. It also makes my joints ache so it's hard to know where tendonitis stops and intolerance starts. However my craving for normal food overcame my knowledge of the pain to come. But just imagine a life without bread, biscuits, cake and it is tough. Also - GF stuff in the supermarkets is INCREDIBLY expensive, so way beyond the means of many. It also doesn't taste as nice on the whole.
I'd rather adapt my diet, but I am so glad that it hasn't come at a time when I have a young family to feed. The thought of having to go without any meals such as baked beans, burgers, fish fingers, battered fish - nightmare. Every single meal would have been incredibly labour-intensive. I have found a recipe for pizza bases using ground cauliflower. Still trying to get up the courage to try it...
