Decent self-help/medical nonfiction. Some good advice and decent information in there, though not all of it is 100% accurate. Of course, as with any self-help book, the author will always overstate their claims. Given the author’s background in nutrition, this book overstates the importance of nutrition. Not to say that nutrition isn’t super important; it is. But your mileage may vary. If you’re eating a shit diet, you will get amazing results from following the advice in this book, though you probably know that already. If you’re eating moderately healthy, you likely would benefit more from other lifestyle changes rather than hyper-focusing on nutrition. Also, and this is my personal opinion, I feel the author suggests supplements a bit too much instead of focusing more on the food side of things. Like for example, the author always talks about the benefits of phytonutrients without really explaining much. Finally, part of the main thesis of the book depends on the idea that our diets are shit, and that’s why we have problems such as ADHD, and depression on the rise. I am not denying that there is a link between nutrition and these illnesses, in fact I do believe in that link. Rather, there are many other factors which cause the rise of these illnesses, and the author overstates the role that nutrition plays in the rise of ADHD and depression. Factors such as changes in social environments, the rise of cell phone technology, erosion of social nets, economic crises, and improvements and changes in diagnostic practices are all factors that I would argue contribute more to the rise of ADHD and depression rates. All in all, I think this book is a decent resource if you wanna learn how to dial in your nutrition for better general health and performance. But it likely won’t be as life changing as it sounds. 3/5
