David Katz is solidly against the consensus of scientists when it comes to food. It's no surprise, he is a friend of Dr. Oz. Thus, it is also no surprise he really likes the latest book from Dr. Marion Nestle, which invokes a vast, corporate soda conspiracy, etc. et al. 

The problem is that it isn't really a serious work, though books like that never are. Like Dr. Oz, Nestle needs a fact checker, writing that the American Council on Science and Health “depends heavily on funding from corporations that have a financial stake in the scientific debate it aims to shape” and that Coca-Cola is a significant sponsor.

It's untrue, which is fine, because it is a pop consumer book promoting fear and doubt about food, so it is right up there with any other diet book. More of a concern is that this kind of “Google University” claim is becoming the norm among people who claim they want to be trusted guides for the public.
