A number of the ideas presented in the book I’ve found in other, much better scientifically grounded publications. It’s certainly important to take care of one’s microbiome and there is evidence out there that gluten, sugar and processed fats are detrimental to health.
I find it difficult to endorse this book, however. It’s very formulaic, dogmatic and sounds like a televangelist on steroids. I hate it when a scientist tries to convince the masses of the truth in scientific discovery through isolated personal interest stories. On top of it all, we’re to believe that all sorts of as-of-yet not understood illnesses are to be successfully cured by avoiding certain foods, taking food supplements, sleeping and exercising regularly. And, of course, if the Whole Life Plan doesn’t work for us, well, we must be truly and deeply sick and need integrative medicine to help us lest we kick the bucket prematurely. huh…
As a European, I can also rant for hours on the blinders-on US-centricity of this book. There are a few strategic references to the rest of the world sprinkled in, but largely non-Americans need not apply. There are zero comments on how the French manage to be significantly healthier than the US population, despite their love affair with croissants and crepes (not to speak of all the flour-based sauces). And what about the Italians with the mountains of pasta and fields of pizza they ingest on a regular basis? He also curiously omits to mention L. bulgaricus—a staple yoghourt bacteria and the reason behind the Japanese’s deep love for Bulgarian yoghourt and trust in its healths benefits.
Finally, I wonder about his repeated recommendation to drink coffee and tea. As a neurologist, he ought to be familiar with the available research on the detrimental effect caffeine has on the brain and the connection between caffeine and mood disorders, particularly anxiety/panic attacks for a measurable portion of the human population.
In all, if you are impressionable and find science difficult to comprehend, this might be a book for you. It might not be the best advice out there, but it’s got good sides and I don’t think it would hurt you.
If, on the other hand, you—like me—get GERD from people who’d like you to trust them with your wellbeing just because they are who they are, you’d be wasting your time with this book. (Or at least get a paper copy so you can use it in the toilet.) There are many other books with a ton of hard science in them, properly citing large meta studies on the subject—you can draw your own conclusions well enough.
The Case against Sugar, The Vegetarian Myth, The Big Fat Surprise, The Omnivore’s Dilemma are just a few of the books I’d suggest.
