Joking aside, for all his past advice he's clearly energetic enough to keep reading, intelligent enough to see the point, and flexible enough to adapt his viewpoint. What's everyone else's excuse. :-)
Have you seen the video where a dietitian angrily (and irrelevantly) argues with Dr. Lane Sebring?
Of course, dense acellular carbohydrate has been around for some time. Loren Cordain makes a meal out of the invention of the roller mill in the latest edition of The Paleo Diet, but you can grind grain pretty fine with millstones, and you can sieve most of the bran out by bolting through cloth. (Useful for also taking out bits of millstone grit on which you might break a tooth, toon doubtless.). Robinson Crusoe even makes sieves on the desert island in Defoe! (His real-life counterpart, Alexander Selkirik, however, seems to have lived mostly of goats' flesh.)
Modern people, of course, have unprecedented levels of "dense acellular carbohydrate" and little sleep and industrial seed oils. It's surprising anyone functions at all.
