Hi,
My family is Gluten-Free also. My husband went through every test you can think of to figure out what was wrong with him, except an allergy test. One day talking with our chiropractor he gave me a book on how to cure one of my husband's conditions and one of the things was to take wheat out of the diet. Not only did it cure the one condition, it cured all of his issues. So we decided to do an allergy test and it came back that he was allergic to wheat, eggs, and milk. I have been able to handle the wheat okay, we've been doing that for almost 2 months now, but the other two I haven't gotten quite down yet.
Anyway, the best place to buy basic GF foods is at Fred Meyer in their health food section. They have an isle and a freezer section. The foods are much more expensive than you would normally pay for, but all GF food is. Things you wouldn't think has Gluten does. For example all soups have gluten in them, anything made with White vinegar has gluten in it so if you are buying things like mayonnaise and salad dressing etc, you must read the label, it has to say cider vinegar or red wine vinegar or it is made with the regular white vinegar that is gluten. For cereal you can use Chex. They have made their corn and rice chex gluten free. If the label says modified food starch, it is usually gluten, if it is from out of the country it definitely has gluten in it. Soy sauce has gluten in it.
I haven't yet found a book or a great recipe for bread products yet. What you want to do is if you shop at stores like Walmart, then you need to go on the outside of the store isles, milk, meat, fruits and veggies. When you go out to eat you need to ask for an allergen paper for their menu. If you live in the Boise area there is a store called Jake's gluten free store. They are open Tuesday-Saturday. They are expensive, but you can get stuff like flour in bulk. And I get daily recipes from www.glutenfreeclub.com which helps out in the gluten area, but not the milk or eggs. Today's recipe was gf macaroni and cheese. Good luck and you will find that if you eat this way also you will become healthy too. Unfortunately Gluten is a product they add to food, but it's expensive to take it out...imagine...
