Except pop-sci books are cancers in and of themselves. The book has some interesting notes but in general prescribes really questionable conclusions to the data. For example, one poster here suggests sleeping less leads to cancer. I don't personally think the article was in any worse taste than the book. Just because someone cites studies doesn't mean they know how to relate data. There's two entire websites dedicated to this sort of fallacy, here (HN) and Reddit. Pop-sci is the most annoying part of the 21st century to me. I'm not convinced anyone actually understands sleep. We know too little and we can die. Too much, and we can die too. "Just enough" is the answer but as far as I can tell no one can quantify what this even means. I sleep enough to be rested. This seems to be >= 6 hours a night. The book would insinuate that I'm going to die of all sorts of terrible diseases as a result. The book itself isn't good science and I don't think a criticism of such a broad-strokes painting of a complicated subject needs to be any more kind. To address your greater point if there's any place where you can throw a rock and find bullshit it's nutrition and health "science". In fact, the industry is so rife with bullshit it's often difficult to tease out actual actionable data. More people need to directly criticize these people in such a fashion until they simply go away.
