The Skeptvet has finally released his long-awaited review of Dr. Jean Dodds' book "Canine Nutrigenomics." The full review can be found here:
Canine Nutrigenomics by Dr. Jean Dodds: Science as Windowdressing | The SkeptVet
To help him review the book, he recruited the help of two experts in small animal nutrition, a cancer specialist, and a nutrigenomics researcher.
The review is quite thorough, and also discusses the validity (or lack thereof) of the Nutriscan saliva test. I won't go into any specific details--those can be found in the link I gave above--but I will quote the conclusion:
Bottom Line
While Dr. Dodds’ book is a mixture of fact and fiction, science and pseudoscience, plausible ideas and outright nonsense, overall the work is deeply misleading. It has little at all to do with nutrigenomics or epigenetics, despite the title and claims to the contrary, and it uses real science primarily to give an aura of legitimacy or authority to claims which are unproven or outright false. References are employed in a manner that suggests an academic research summary with conclusions based on scientific evidence. The reality is that the book is a collection of opinions, some plausible and some not, supported in most cases by very little evidence and in some cases clearly contradicted by this evidence. The references employed are often simply other people’s opinions or, in some cases, Dr. Dodds’ own opinions reprinted elsewhere. The recommendations made for and against specific feeding practices and dietary supplements are mostly typical for proponents of alternative medicine, and they stem from ideology and philosophical beliefs rather than scientific evidence. Occasionally, such claims turn out to be true, in the manner of a broken clock which happens to be right twice a day but this has little to do with the underlying principles. And while there are a few evidence-based claims here and there in the book, and some recommendations I would agree with, overall Canine Nutrigenomics is misleading, misguided, and in conflict with the best evidence and expert consensus in veterinary nutrition.
