BTW, the protein in oats that can cause intolerance is avenin. I think I am intolerant of it, as I improved a lot after quitting gluten, but then relapsed when I had some oats, so ditched them. Always hard to be sure of the causes of symptoms, but I decided to be on the safe side, and to be honest I really don't like oats anyway!
I also seem to be one of those who can't tolerate buckwheat - or not much anyway (and I know it's not a grain).
How do folks here get on with quinoa? I find it very bland, but I might be able to make it palatable with spices, etc., it might be a good way for a vegan to get more protein.
