There can be a difference between the academic discussion of edibility and what we as individuals actually choose to eat.

On an individual basis I also consider the addictive quality of the food.  By this I mean that if I observe a tendency to overeat a particular food, to go to it even when I am not actually hungry, then this raises a personal red flag to me.  Many writers in the field of weight control raise the issue that intolerance foods seem to carry an addictive character for the individuals for whom they are intolerance foods.  I find this appears to be true for me.

Therefore, regardless of the academic discussions, if I can't eat just one potato, without finding myself craving potatos again the next day, to list just one example, then I don't believe that it is in my best interest to eat potatos.  They were certainly not available to my predominately Europeon gene pool until the last few hundred years.

I am personally also most tempted to justify my non-paleo or quasi-paleo food choices.  rationalization is another clue that i'm not following my own best interests.

Over time I have found that almost every food that I have this addictive draw to is a non-paleo or questionably paleo food.  This conforms for me the likelihood that my body should "believe" in purist paleo, regardless of the academic conclusions.
