I have celiac disease, and no way am I going to ever eat gluten if I can help it. My GF and my family are very helpful-all that needs to be done is to fix whatever they want, but tell me what I can eat besides the protein dish. If it is only salad, that is plenty enough for me. Often that is all I fix myself at home. Eating is not huge in my life- though I rarely miss a nice piece of salmon or halibut or cod if I can afford it that day.
Traveling can be a challenge, but I have found that expensive restaurants, or in one's own city places where you have taken the time to make some relationships seem completely trustworthy. Ethnic places can be very problematical, I think partly because of language, and partly because wheat intolerance is almost exclusively an illness of Europeans. Overall finding safe food for a celiac has all changed very much for the better over the 20 years or so that I have been aware of my diagnosis. For a long time if I went out after a dance say, I had only a drink and some nuts that I carried on my person. You can go a long time on nuts. Just don't eat any carb or you can bonk.
Eating to avoid gluten is very simple in one's own kitchen. I have never prepared or bought a "gluten free" food that was conceived or marketed as gluten free. Only thing I miss is pizza in Southern New England, but I will never again have any. But big deal-neither will I ever sleep with 99.9999999999999999999999999 x10 to the whatever % of the attractive women I see all over the place. If I am going to feel sorry for myself, it won't be over pizza.
