Lewis Blood Group System

Incidence         Whites          Blacks
LeA+, LeB-  =    22%             23%  (non-secretor)
LeA-, LeB+  =    72%             55%  (secretor)
LeA-, LeB-   =    6%               22%  (double negative; should eat like a non-secretor)
LeA+, LeB+ =    rare              rare

I got these numbers from a presentation on Serotyping Techniques by Thomas A.Kruzel, M.T., N. D., Southwest College of Naturopathic Medicine & Health Sciences

I don't know if the numbers are for the world, USA, or some other area.

Since the list is limited to Whites and Blacks, it's presumably not for the whole world.  I would guess it's just the U.S.

Even so, it seems odd that the LeA+B- category of unequivocal nonnies amounts to 22-23% of the White+Black population.  I thought the figure for all nonnies was more like 15-20%.

Does this mean that there's a smaller percent of nonnies among Asian-Americans, Hispanics, and other groups?  Or that the U.S. has a higher percentage of nonnies than the rest of the world?  Or am I overlooking something obvious?

The frequencies among Asians are similiar for caucasians;however,though there are three separate non-secretor variants among taiwanese. Meaning there are three separate mutations on the Se gene to produce these non-secretor variants. Among the Le(a-b-) populations the majority (80%) are secretors.

I assume the *half* in her sig line describes *O* rather than *nonnie*.  I took it to mean her A gene hides a recessive O.  My husband and I both know we're not just As but A-Os as we each have an O parent who could donate nothing other than an O gene to our conceptions.

Good reminder that if your salivary secretor test comes back as secretor, but you feel you may benefit from the non-secretor diet, you may well be a lewis double-negative, especially for the African American population.
