Questions About Lectins

Type B and Corn Lectin


Many thanks for your wonderful work. I think I can speak for the hundreds of thousands of people who have been so helped by your great work. I discussed your theory with the dietician who works at the university clinic where I am treated for inflammatory bowel disease who just scoffed at the theory that my improvement could have been the result of following the type B diet. In particular she said that there was no evidence that corn contained any lectin that specifically agglutinated type B blood. I am 80% better -and off of most of my medicines- thanks to your book. God Bless.


In general I've found most dieticians to be quite ignorant of the large lectin literature to be found on such easily accessed venues such as MEDLINE or OVID. My suspicion is that because their education is insufficient in the basic rudiments of immunology and hematology, they cannot appreciate much of the lectin literature since it is quite complex. Sadly, your interaction is typical of the reaction of most "ADA-droids" when a little intellectual curiosity could have opened up new pathways of thinking.

That corn lectins (Zea Mays Agglutinin) is a d-galactose specific lectin has been known for over 25 years (1). The results of serological studies of Zea mays everta seed extracts with anti-B specificity showed the lectin will agglutinate type B and AB red blood cells. Interestingly corn lectin agglutinated A1B red blood cells significantly more weakly than A2B red blood cells.

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.
