As much attention as “paleo” has received as the latest fad diet, the people who are looking into its basic tenet as a guide to what a human is meant to experience – how we are to live, not just to eat – are much fewer.
It may be understandable only too easily.
“Do you want us to go back to the Stone Age?!?” is a popular reaction to e.g. environmentalists’ calls for degrowth and to remember lessons from earlier times, after all – and surely we wouldn’t want to literally live like cavemen.
That said, if you believe that maybe we are not physiologically well-adapted to eating modern foodstuffs (yet), it is all the more likely that we are not adapted to many other modern conditions.
