Hey, I Just Report The Facts As I Learn Them


I'm confused. In your book ER4YT, you stated several times that O's live longer. Now I'm reading that B blood individuals attain more advanced age. I have found much of your work to be contradictory, Why?


You make it sound as if that were a bad thing. A lot of data is contradictory; that is just one of the delightful aspects of science, and especially the science of epidemiology. That is what distinguishes science from other intellectual pursuits. The study (1) that I was aware of much earlier, looked at elderly Italian doctors and concluded that there is an excess of group O. This other study (2) asserts that it is group B that is longer lived was just one that I came across much later. Which is correct? It is hard to say, since the indigenous diets may or may not fit the profile diet for that type as I recommend it.

The Ask Dr. D'Adamo internet advice column ran from 1996 to 2009, at which time Dr. D'Adamo's teaching and programming responsibilities no longer allowed him to devote time and resources to directly answering visitor questions. However we've recently reorganized this treasure-trove of material and made it again available to his readership. He occasionally posts new entries. These are marked with a NEW tag.
