Most of the paleo junk food I've seen has been variations on a theme of dark chocolate and coconuts. I don't have any nutrition labels to hand (paleo junk food is
expensive), but I wouldn't write it off as unhealthy without seeing what's in it.
Then again, the reason I can't stick to paleo is the slippery slope from 95% dark chocolate to Toblerones, so maybe it's better to cut chocolate out altogether.
