I already cooked 95% of my food from whole foods (if we count bread and cheese as whole foods), so the cooking at home transition has been very easy. Dealing with the outside world has been harder. It's still an effort to not accept a taste of someone's food at dinner, or to not grab a tortilla chip out of a basket because it was probably fried in contamination oil. Some of me wants to just not eat outside my apartment, but eating and socializing are closely intertwined. I also live in a city where there are gluten-free options in numerous restaurants, so it also seems paranoid to not eat out ever. And hey, I LIKE to eat out.
Good point. It's easier to stay gluten free if you already prepare or cook most of your foods from whole foods, rather than relying on processed or fast foods, which often contain gluten. Also preparing your own foods is less expensive than relying on gluten free processed products. Many people who have difficulty with gluten free dietn have never really learned to cook.
