I really don't think it is fair to complain that The Case Against Sugar repeats his previous work, because it really does not. There's prominent mention of a couple of pivotal studies, like the New Zealand atolls and the experience of British Empire physicians caring for aboriginal peoples and documenting their encounters with Western Civilization; but it would be wrong not to.

There's lots of new stuff, too, like Big Sugar with a stranglehold on research and their PR efforts, and more about Ancel Keys and how he shaped the new direction of nutritional thought. There's also a whole new chapter on gout and its relationship to sugar.

I'm a huge fan of Good Calories, Bad Calories, but I suspect his publisher would prefer he not write doorstoppers any more.
