I have no background in science, and was totally sucked in by one of Gary Taubes' books precisely because of that. A lot of these authors are incredibly biased and happy to filter science to you in a way that's profitable for them. Volek and his Superstarch is someone I have little respect for. If you haven't come across it, and you're willing to listen to a different viewpoint, I really recommend http://carbsanity.blogspot.com Have a search for Attia, Taubes, Volek etc and you may find some surprises.
