Is Taubes giving the impression that Reaven said that sugar caused the problem in the first place, as Stephan says? There's misrepresenting of what a person says, and then there's having a different interpretation or hypothesis about the implications of a person's research than they have themselves, these are two different things. Not the first time Taubes has been accused of misrepresentation of Reaven.

I know of a number of low fat researchers whose work can easily be put into a different light, and seen as just as supportive of low carb as they ever were of low fat.
