Eat Right For Your Type :: The Official Blood Type Diet Site Blood Types - Lifestyle and diet suggestions for your blood type. Does anyone have any legitimate claims to trash this? I don't really buy into it, but if it is (for some strange reason that we cannot yet fully explain) correct, then I (type O+) am doing my job by eating tons of chicken and avoiding beans.

Does anyone have any support/attacks for this that are more grounded than those PROVEN penis enlargement techniques?
