Oatmeal

I am striving to avoid gluten, and my naturopath gave me a list of grains to avoid, which included oatmeal. But I’ve since read that it doesn’t contain gluten, rather it ‘can’ be contaminated during processing. So if that is the case, then oat groats should be ok?

Another question, I am enjoying the raw dessert recipes I’ve tried so far, but I’d like to cut back on the nuts. I wonder if anyone has had any experience with substituting grains for some of the nuts. ie. pie crust made with dates and ground up nuts, maybe add some ground up oats?
