Dr. D'Adamo,
I have discovered your Web pages via the Symbolistics connection as I am one of the Company. I could not help but comment on some of the information as I am a Blood Group Serologist. I regret to say I have not read your book as yet but intend to do so.
A few interesting facts about Blood Groups which you may or may not be aware of.
Blood Group B has a relatively high frequency amongst villages close to major English Rivers, this is a result of marauding Vikings who had a high percentage of Group B's.
I assume you are aware of an excellent very large book on the relationship of Blood Groups and Disease which was written by an individual whose name I have forgotten but I do know he lived on the Island of Jersey (UK). This book also covers not only ABO groups but many of the other Blood Group Antigens.
An incidence of Blood Group pp in Northern Scandinavia is thought to be due to natural selection of individuals who produced naturally occuring P antibody which is antagonistic to Diphylabothrum latum ( fish tape worm) Raw fish with tape worms used to be a fairly common item on the menu.
Many plants as you know produce Lectins, many also show antigenicity very similar to Blood Group Antigens. This can also be found in Pollens and it is possible to agglutinate some pollens with Blood Group Antibody. The obvious subsequent effect is that it will influence our health. As similar species and strains should show a variety of Antigenicity it must therefore follow that not all strains of grain will have the same effect. It of course could also be country specific as seed stocks are not often transferred between nations but bred within particular countries to provide a strain specific to the local environment.
I will place a link to your web site in my other companies capacity
Sanguin of course being derived from the Latin name for Blood. You will also find some other interesting links there as well.
