I didn't read it as , judging from reports he has no formal training in medicine or nutrition, making his claims rather less reliable than the masses of scientists and studies

 he criticises. Taubes is a classic example of the type of scientist who is pretty good within his own field(in this case physics) but then , much like the vitamin-C-supplement-fanatic Linus Pauling and Richard Wrangham and others, then branches out into other fields he is somewhat less qualified in, to put it mildly.

 

That said, I plan on reviewing his book on a particular dietary website 

within the next 6 months, given that he has been given rather a lot of attention on the various forums, if only to debunk some of his claims re saturated fat etc.
