I disagree. It should be foods that our ancestors ate on a regular 
basis. Long enough to have adapted to them. But the big killer here 
is none of those early paleo people that made it to the New World 
were our ancestors.

Only if you have some Native American ancestry could there have been 
an adaptation to potatoes.
