The cons: the thought processes and organization of this book are not the easy to follow. It creates what feels like a "straw man" argument to be repudiated later in the book. I found much of the writing about the discovery of electricity and history of the industrial revolution to be unecessary and irritating. (Get to the point, please?) The first 140 pages can be summed up that a consequence of the industrial revolution were changes in cooking and dietary patterns. Those changes were based on no longer cooking with wood fuels, and conseqently, no longer using wood ash as fertilizer and/or any culinary ash in cooking.
The first 140 pages left me with a feeling that I was reading a solicitation for a multi-level marketing scam. In that situation, the sales person discusses a wide variety of issues without revealing the product or service at issue. This book would more effectively communicate the pertinent information if edited to 1/3rd of its current length.
The pros: Wallach's primary target audience appears to be the lay person, -certainly not the health care establishment. His primary take-home lesson is that mineral deficiencies are the root cause of "pica", -an innate craving to satisfy mineral deficiencies. Pica most often manifests as "the munchies". And the result has been pandemic obesity. And the result of obesity is a host of related diseases. He argues a excellent case for the social epidemiology of obesity.
The presentation and organization of this book could be improved. But it's encouraging to see an MD speak something other than the mantra of pharmaceutical companies.
