Does Blood Type B Live Longer?
Immune responses of healthy humans 83-104 years of age.

The immune responses of 19 healthy people 83-104 years of age were compared to those of younger healthy persons. A decline in mitogen response to concanavalin A and pokeweed mitogen, but not to phytohemagglutinin, was observed. Positive skin test to two recall antigens occurred in only 5 of the 19 aged people; 4 of these 5 reported a history of blood transfusion. Antibody titers were elevated for persistent DNA viruses but not for RNA viruses. An excess of ABO blood type B was found, but no human leukocyte antigen (HLA)-A or HLA-B type was found in elevated proportion.
It has been my feeling (for quite a long time) that group B individuals on average are a bit healthier than their counterparts. Since they tend to fall almost invariably between A and O with regard to disease susceptibilities, this 'tempering effect' can be expected to translate into a higher percentage of type B individuals attaining a more advanced age.
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.
Rather than trying to make a one-size fits all blend, Dr. D'Adamo specially formulated his Polyvite multivitamins for each blood type, giving people the specific vitamins that help their body best.
