A challenge is that with this debate (say organic vs GMO) both sides have a lot at stake financially and you can make this argument either way. How then should one decide what to trust and read?
I recognize that genetic modification is sometimes used to enable greater use of these chemicals (eg roundup ready grains).
Which is totally not a guarantee, I freely admit.
The odd 'paleo' diet is nothing we're equipped to handle anymore. Nobody has eaten like that for 100,000 years, and we've moved on biologically?
