Potatoes may not suit everybody but. the general
negative attitude to potatoes and the mostly
positive acceptance of sweet potatoes in the
Paleo/Primal community has always perplexed me...
after all... both have been discovered/cultivated
by the indigenous people of Central and South
America for MILLENNIA!

<<The potato was first domesticated in the region
of modern-day southern Peru and extreme
north-western Bolivia between 8000 and 5000 BC>>

<< In Central America, sweet potatoes were
domesticated at least 5,000 years ago. / In South
America, Peruvian sweet potato remnants dating as
far back as 8000 BC have been found.>>

[Jim]  Potatoes never.  Not only are they nearly
100% carbohydrate, but they
are poisonous.  Not even remotely arguably paleo,
in my opinion.

[Ron] They can become poisonous from exposure to
sunlight, but I don't know
which natives cultivated them and whether they did
so for long enough to
adapt to eating them. Do you? 

I don't either.  Thus caution.
