The problem is that this is yet another revolution which reverses the conclusions and advice of the previous one. It's not a revolution like modern physics, which qualified and re-explained classical mechanics. It's more like the French revolution. Off with the heads of the anti-fatists, salute the anti-carb flag... until the next reversal which will surely reject the conclusions of the current one. The situation is much like with artifical intelligence in the early days - trying to boil the problem down to a few simple rules. Until we are willing to accept the huge complexity involved in the problem we do more harm than good. There is no single useful scale on which to judge foods. (See lukesandberg's comment and link below.) In the meantime I recommend you eat like a caveman.
