Response To Critics (If You Care)


My conservative, normally omnivorous brother pointed to this website which jumps all over your program. Have you answered any of this guy's concerns? By the way, I find your program for Type A works great!


That is a very old and biased article that was cross-posted to several vegetarian websites. It was answered long ago.

Its major problem with my theory is that I allow some blood types to eat animal protein; thus the author's gripe is not just with me, but also with all the other 'high protein diets' out there as well. I suppose if I had just published the type A diet he would have not had much of a problem with my theory.

His points that attempt to refute the thousands of published studies linking blood type to many diseases and biological functions are simplistic and display no great appreciation or understanding of much of the material that he attempts to contradict.

Unfortunately it was not the science that resulted in his critique, but rather the conclusions.

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.
