Hi, welcome to the forum. My family eats a meat-free, dairy-free, egg-free, gluten-free, hydrogenated oil-free, corn syrup-free, dye-free, preservative-free, organic whole foods diet. Additionally, my son is corn-free and soy-free. Thank goodness we arrived here over time! It can be overwhelming to remove favorite food groups from the diet, but it can be done! Our motivation was to feel better. Once you're feeling better, that's the motivation not to go back!

I prepare our food. We brown bag it (or haul our cooler) if we must eat away from home. Here are some ideas for food to eat and/or substitutions.

Milk substitute --> soymilk, almond milk, rice milk
Cheese substitute --> there are soy cheeses, but we consider them "processed foods" and no longer eat them. We've found that many foods topped with cheese are just as good without ... once you get used to it!
Gluten-free grains --> we eat brown rice, millet, quinoa, amaranth, buckwheat
Nuts and seeds --> we enjoy almonds, walnuts, cashews, flax seeds, sesame seeds, etc.
Beans --> we eat a lot of black beans, pinto beans, chickpeas, etc.

Fast food for us --> We do use pre-packaged rice cakes, Tinkyada rice pasta, and rice tortillas. The rice tortillas can be toasted in a skillet to make "crackers" or "pita". It can be baked in the oven to make a quick "pizza crust". Rice cakes are good with various nut butters. My son especially likes almond butter and cashew butter on his.

Recipes --> Check out the recipe threads that are just getting started in this forum. You'll find some good ideas! Also, I really like Food Allergy Survival Guide by Vesanto Melina. I have yet to purchase it since it is readily available at my library.
