The deal is there is no general consensus, thus we are each left to figure it out ourselves.
I seem to have found something that helps me tolerate sweet potatoes, potatoes and other foods of varying carbiness a bit better and improved my blood glucose modulation--foods rich in resistant starch, inulin and other prebiotics, especially the RS. So tubers are now closer to "Paleo"/beneficial for me, though I still generally tolerate raw carbs better than cooked.
Oddly enough, mung beans have so far turned out to be one of my more beneficial foods. I had never heard of them, much less guessed such a thing.
