Without Thiamine, our mitochondria don't function properly, affecting different organs, and causing all sorts of diseases. I find it fascinating how insufficient Thiamine can affect the mitochondria. Vaccinations and so many things can cause Thiamine deficiency disorders. Not to worry, I simply like to add in references for future readers. Further, it is ethically questionable to perpetuate unsubstantiated claims. It is a terrible shame that the Putnam & Sons were/are willing to publish such manipulative nonsense. The rest of the book essentially makes broad recommendations based on an unsubstantiated relationship (namely blood type to dietary function). 392pp), stating that each person needs to be treated as an utterly unique individual (a fallacy right off the bat). It is interesting that D'Adamo quotes his father (also a Naturopath) on page XV of the introduction (D'Adamo, Peter J, 4 Blood Types, 4 Diets: Eat Right 4/For Your Type, New York: Putnam and Sons. Combined with evidence-based evaluations, it is better advice to determine your own physiological responses to various foods and adjust your diet accordingly. It could be he is right, but it could also be that he is decidedly wrong. Until such time as solid, repeatable evidence demonstrating that blood type is a reliable predictor of food sensitivity, it is unproductive to follow D'Adamo's advice. Without repeatable statistically verifiable evidence, such stories are just 'affirming the consequent', ' post hoc' and false premise logical fallacies. They are stories deliberately selected to prove a claim. The scientific method is a collection of procedures designed to account for our natural tendency to see patterns where none exist and for our tendency to seek confirmation of our biases instead of solid proof. It must be true!' People with AB- might say 'I must be a fluke because I don't have type O blood'. But without proper critical analysis, people with celiac and type O blood will be inclined to say 'wow, I have type O blood and celiac.

Given the prevalence of type O it is reasonable to assume that a large percentage of the total number of people with either condition will have type O blood. There is no research supporting his claims of a correlative (much less causal) relationship between blood type and celiac or gluten sensitivity. It is pure speculation supported by anecdote presented as fact. Whether or not D'Adamo has an PhD or even an MD (which he doesn't) the main problem is that the book is based on an untested hypothesis.
