Wheat starch theoretically has no wheat proteins, it is only the starch. But, how can you be sure all protiens were removed during processing? I don't chance it.

My entire family has intolerances to food. So, we avoided some of the stuff we already had intolerances to. But, I did not know my dad had celiac (diagnosed at 3 but told outgrew it, but you can't outgrow it, explains a lot about him). We never avoided wheat. In fact, I baked several loaves of bread a week. But, it turns out Samantha, and myself, probabaly have celiac.
www.celiac.com has a lot of information. There is also a Canadian celiac website I actually find better but I can find the link.
www.gfcfdiet.com has a lot of info about avoiding gluten and dairy. We are dairy and gluten free.
