When I was first diagnosed, you couldn't buy groceries or eat out _anywhere_. Now, pretty much every restaurant has gluten free options marked on their menu; every supermarket has a wide range of bread, flour, cake mixes, biscuits, and so on; and manufacturers of packaged food are swapping out incidental gluten-free ingredients like wheat starch for gluten-free alternatives. You can bet that's because of people that think gluten-free food is "good for you", rather than the much smaller group of Coeliacs ourselves.
