Hi Kerri,

I'm also new to this group but I've been doing the funky diet thing for about 8 years. Congratulations on finding some reasons to change your diet and improve your health. This is a good time to be a 'special ed' eater. There are an amazing number of products and recipes to help you keep your goals. Let me know if there is anything in particular you are trying to replace. Here are a few of my favorites:

Almond Breeze Coconut Milk Almond Milk blend (for my money this is the best milk replacement since I don't do soy) Get the sweetened version at 60 calories per 8 oz.
Daiya products: this cheese-like substance is gluten free and melts!!! You can do pizza and grilled cheese with this stuff.
Applegate farms makes some great pepperoni, salami and lunch meats that don't have traces of dairy.

Udi's Gluten Free bread products. They have a wide variety and all except some of the cookies/desserts are dairy free. Good pizza crusts!!!
Bob's Red Mill mixes. There are many options but I like these as they are typically cheaper and often lower fat & sugar

AMAZON!!! There are tons of great allergen free foods available there. Orgran, Scharr, Zing, etc. So if you don't live in an area where specialty foods are readily available, order on line.

Beware:
I'm not sure how sensitive you are at this time, but as you decrease exposure, you are likely to become more sensitive to things gluten and dairy. If you are or become very sensitive: watch out for things like salami (lactic acid starter culture is typically from milk), chocolate made in the US almost always has diary protein in it (and I don't mean just the the milk chocolate, either).
Also, keep checking ingredients. Manufacturers change their ingredients so even if it was OK last month, it might not be OK today. Worse, when a manufacturer changes their ingredients they have 6 months to update their packaging. If you have a bad reaction to something, it might not be your imagination.

Retest!
Not sure how you were diagnosed and if you feel better without gluten & dairy it doesn't matter. However, do consider retesting every once in a while. I avoid gluten dairy & soy. However, on my first time through an elimination diet I only discovered dairy & soy. Eventually I was good enough at keeping them out of my food that I realized I had symptoms from something else. Retested and had an outrageously positive reaction to gluten. I think initially I just had test burnout and didn't figure it out.

Good luck! I know that for me figuring out my food sensitivities has been the most astonishingly positive thing I've done in my adult life. Gail
