Instaread Summary, Analysis & Review of Peter J. D’Adamo's Eat Right for Your Type The Individualized Diet Solution to Staying Healthy, Living Longer & Achieving Your Ideal Weight
One out of five stars
I spent far more time evaluating this summary than I normally do. The topic of blood type (the standard set of A, B, AB, O), how they evolved and the differential role they play in physiology is on the surface a fascinating one. Therefore, I did a lot of online research in evaluating the claims made in the book as expressed in the summary.
Unfortunately, my conclusions were that it is largely unsubstantiated pseudo-scientific nonsense. Some of the very contradictions appear in the summary itself. For example, key takeaway five contains the following two contradictory phrases:
“Blood type plays a role in how individuals react to everyday stressors.”
“Although there has been little scientific investigation into the link between blood type and stress response, . . . “
This illustrates the form of the summary, a statement is made as if it has been established, followed by another that clearly states that it has not. Or no real evidence in support.
I found some research linking some of the other blood types to resistance to specific diseases, but nothing solid regarding blood types affecting the relative efficacy of the consumption of specific foods. There is nothing in the list of references (scientific literature) cited in the summary supporting the primary theme of eating to your blood type. There is also no critical analysis in the summary, unusual because there is no scientific evidence to support the claims.
The best comments that I discovered about the content of the book (the significance of blood types) is:
“Isn’t it amazing?” says Ajit Varki, a biologist at the University of California, San Diego. “Almost a hundred years after the Nobel Prize was awarded for this discovery, we still don’t know exactly what they’re for.”
“There is no direct evidence supporting the health effects of the ABO blood type diet,” says Emmy De Buck of the Belgian Red Cross-Flanders.”
Both of these quotes are from
and are consistent with all the other scientific literature I could find. The second comment was made after a thorough examination of over 1000 studies examining links between blood types and diet.
