Type O blood is the most recent development in humans, and so naturally the most adapted to our current diets. If you are type O, you don't even need to bother with the book, essentially.

If you are drowning in your own phlegm--and many of the retirees here in my mom's community are--you are almost surely not type O, and will benefit from finding out what you are eating that is causing all the snot.
