Tom: >> Is grain close enough in chemical composition to say, raw starchy tubers, >> that we can digest it OK? Jean-Louis Tu <[log in to unmask]>: >IMO, grain contains more protein. As for the starch part, I don't find >unsprouted grains very tasty (which may indicate that they are not >very digestible), and sprouted grains contain less starch. Tom: One minor point on grains and protein. Nuts and certain seeds, are also original foods, and contain significant amounts of protein. So perhaps I should have compared grain to something "between" (in composition) nuts and starchy tubers. I agree with you that raw, unsprouted grains are not very enjoyable.
