Best/worst gluten and dairy substitutes?

Both should avoid gluten.

There is absolutely NO benefit to avoiding gluten if you are genetically able to produce the gluten-digesting enzymes. In fact, such a person is missing out on a valuable protein source.

Thanks, Knot, that made a lot of sense. I don't know why these people I met avoid gluten. They're also trying to lose weight so maybe there's something there.
