The main  problem with ERFYT is that blood groups aren't as simple as
just ABO  I suspect, if there is anything in the theory at all, that the
ABO genotype plays a part.
eg group A people can be AA or AO depending on what they have inherited
- It could be that the A's and B's  who do well on the type O diet are
actually AO or BO genetically .
