Gluten free grains

So what if a major portion of the population does not digest well the gluten protein in some grains? What if gluten is hard on the digestive system and even affects the ability to burn fat? What if gluten .. or gliadin in gluten ... is an allergen. Lots of information .. and probably mis-information... exists on the internet. Check out "gliadin" on your favorite search engine.
I am experienting with eating "gluten free".

Some other grain choices (gluten free):
amaranth, kasha, millet, quinoa, tef, wild rice... and of course a marvelous selection of rice... brown, basmatic, aromatic, long grain, short grain, arborino, etc.

Quinoa, available in bulk at food co-ops, is especially tasty, I think.
Oats, organic and processed in a wheat-free facility, may be a possibility.
I am reluctant to give up my breakfast (organic) oatmeal. Bob's Red Mill has gluten free rolled oats, which most people can tolerate.
