Ron: Based on the examples you give, it seems you prescribe based on outliers, to begin by eating anything at all in the world and only prohibiting when obvious negative health signs present themselves. But would it not make more sense to start with core paleo — which, when it comes down to it, isn’t that hard to define — and then slowly and deliberately add in non-paleo items one by one?  It’s funny you mention Todd.  He was always seemingly so threatened by this approach.  But does it not make the most sense?  Is core paleo *unhealthy* for anyone?   Does anyone *require* non-paleo foods to survive?
