I was wondering about this too. The Mediterranean Diet and the French Paradox both rely HEAVILY on grains. The French especially love their dairy. I'm still following PB, but the thought has crossed my mind: is eating an all natural, homemade French baguette AS bad (does it deserve the same intensity of rejection) as cooking with partially hydrogenated soybean oil? I understand that neither are "primal" and that the focus of PB isn't just on heart health and weight....but it would appear that there are some bread and cattle cultures that are doing just fine living more-than-primally.
