The book is divided into two parts. The first part addresses common killers and how they can be mitigated, prevented or reversed through nutrition. The second part of the book covers specific food groups and gives guidelines for their regular consumption.
The book is meticulously researched, with every claim backed up by real, peer-reviewed science. When reading it, it felt like every other sentence had a citation. It’s unlikely that the average reader could actually go through each of the cited studies to confirm that the conclusions presented in the book are an accurate representation of the paper, or if they’ve been skewed to better fit Dr. Greger’s message.
The book grew out of NutritionFacts.org, a non-profit organization started by Dr. Greger with the goal of reading and understanding as much of the published science on nutrition and health as possible, and presenting the results as dietary guidelines actionable for normal people. (Unfortunately the website focuses primarily on video dissemination, which for me is an ineffective means of information transmission. I prefer plain text. Hence the book.)
Dr. Greger is largely opposed to consuming meat. He eschews terms like “vegetarianism”, instead preferring to advocate for what he calls an evidence-based diet centered on whole-food, plant based nutrition. I like to consume flesh, do not intend to stop, and think the consumption of it does provide important nutritional value (a point on which the doctor does acquiesce). Many of his warnings about flesh eating are less about the nutritional value of the meat itself and more about the cleanliness of the production and preparation environment. However, if you can look past the anti-meat tendencies and the possible biases in which type of research is reported on, there is still a lot of very good data in the book. It’s one of the best owner’s manuals for the body that I have read.
