from the paper that paleomom references
http://file.scirp.org/pdf/FNS_2013011516575568.pdf (which I have only glanced through) it would seem that teff, quinoa, amaranth, sorghum, buckwheat, hemp and sesame would be the best bets.
But this is about allergic responses. We have three issues: the way that dysbiosis and acellular carbs cause a breakdown of the mucosal layer: the way that gliadin and other pro permeability factors increase permeability; and then the presentation of pood particles to the immune system.
My approach taking heavily from john bagnulo
, has been to try to stick to cellular carbs, take plently of anti permeability agents and avoiding pro permeability agents, and avoid anything that I know makes me feel worse.
And thanks for the link, I read it about two years ago and had completely forgotten about this crossreactivity issue. I wil have to get some of the better grains if I continue with the porridges.
