I chose new primal, though I never eat rice. I don't see why sweet potatoes are not primal.
My 20% is too much dairy (though all grassfed, fermented and sometimes raw), honey, a dark chocolate bar about once a week if I'm out of better food aannd occasions where I can't help but to eat unhealthy. When I'm with friends I just eat nothing. But when I'm with my dad for a longer period of time I'll have to eat crap unfortunately.
