Hi, I have to eat this type of a diet for life so I know what you're going through. Whole Foods has a good section, the Giant in Cardinal Forest has a section now as well by the pharmacy and they have cereals that are good but they do have sugar in them. I also shop at Healthway in Springfield Plaza (near Buy-Buy Baby and Trader Joe's and K-Mart). They have frozen foods - including meals and pizza that are good. Pretzels by Glutano are good and they have animal cookies that are good.
You can go on to gluten-solutions website and order online (the same products and near the same price with a 10% discount). When I go out to eat, I ask the waiter/waitress if they have a special menu (many do now) or ask for sandwiches without the bread or ask if they are able to make what I want w/o the bread or breading. If it's not pre-mixed or bought, they usually are REALLY good at accommodating you. It will take a bit longer sometimes but not that bad. The worse part is pizza places but now some of them are getting better about having other types of food. Hope this helps and you can also order special cookbooks online or I found a gluten-free recipe for any type of food you could imagine - including pancakes and two of those were EXCELLENT and tasted like REAL pancakes. It's Living Without Magazine and has LOTS of recipes.
For bread - Whole foods has a "sandwich" bread that I REALLY LIKE and it tastes more like regular bread. There is a Prairie Bread if he can eat millet and buckwheat that is also good. Pecan or Almond rice bread is good but has some sugar and the cinnamon raisin bread is really good.
