you have to love it when a 'healer' comes in and gets all offended when SOMEONE IS HEALING AND FEELING BETTER AFTER FINDING SOMETHING THAT WORKS FOR THEM.
i think it is called petty tyrant syndrome, or curezone grandiose healer syndrome.
i am VERY skeptical of people/'healers' who can't even function at the baseline of human decency and just be happy for someone else's success regardless of whether they were the source of it or not. it's a big universe and some folks just can't see that they are not the center of it.
i assume you have looked into sally fallon's books, the Blood Type Diet (which lam basically stole from peter d'adamo), and all of the various paleo websites. a lot of this could turn out to be genetic.
