I read a lot of books on nutrition. This one is now one of my favorites.
I think this book holds its own place in nutrition and the history of how we got to where we are today. It is written in a style that is easily accessible to those people who are both up on nutrition as well as those who are simply looking for someone to tell them what to eat. While the book doesn’t tell anyone what to eat, it makes a point of telling people that everyone is different and even explains the differences.
The book is divided into 3 sections. The first section basically tells the story of how the politics and moneyed interests trumped actual science. It's easily readable and is a good start. The second section, defines science terms and takes us through a scientific study. The book then explains the history of nutrition and disease through some of these studies, including Ancel Keys and Yudkin. The book describes both of these pioneers in reasonable terms. Certainly more reasonably then they described each other.
Finally the third section looks into 3 different diets; Mediterranean, Paleo/Primal and Veganism/Vegetarianism. The book looks at them both for what they correlate on (not a lot in terms of foods to eat) and what they both restrict (very similar restrictions in many cases). The book goes on to point out that since we are all individuals, it’s up to us to find the diet that works for us, but at the very least, we can start by subtracting what those three diets all leave out (processed, refined foods, sugars, trans-fats, PUFAs)
I think everyone should read this book. Vegans, Paleo/Primal, and mostly people who hear all the sound bites and are totally confused as to what to eat. Her main message is look at the science, look at what works for you and don't just take anyone's word for anything. Correlation does not equal causation.
