This is just my own fairly unsophisticated take on this
after doing a tiny bit of research. A lot of people around
me (this being Japan and all) are pretty into the idea of
blood types influencing personality, etc., so over the
years I have looked into it from time to time. I recently
read that there was an excess of some kind of cancer among
people with type A, but the "excess" was only something
like 1.05 compared to an expected value of 1.00. The
authors said it was "small but statistically significant."
Which means, it's a "statistically significant" difference
but not much of a "clinically significant" one. I suspect
that it may be similar with ABO and diet, that there may
really be some small differences but they are not really
sufficient to nullify the fact that humans are generally
designed for a pretty equivalent diet. There may be
differences in specific foods, but basically we are all
meat, fish, insect, green vegetable, nut, fruit eaters.
