The idea of going paleo is attractive to someone like me, who feels he is living in an unhealthy, vapid world of consumerism. The sprawl of modern humanity is clearly unhealthy for earth’s biodiversity and for the stability of our climate. And it makes a lot of sense that our modern lifestyle would prove unhealthy for us: Our bodies were shaped for hundreds of thousands of years to hunt and gather -- and yet we insist on sitting down all day while eating things our ancestors would not recognize as food. We keep introducing new things that don’t fit into the natural environment or the environment of our bodies.
There’s a natural yearning to backtrack -- to get back to the garden. But there’s a problem, usually unacknowledged, with the whole paleo phenomenon: Going back to a hunter-gatherer's meat-heavy diet is impossible unless we cull our population to pre-agricultural levels. There have been no reasonable proposals for achieving quick population reduction. And so we are faced with a sad reality: We can’t ever go home again.
In this week’s New Yorker, Elizabeth Kolbert wrote about putting her family on the paleo diet while reviewing “a small library of what might be called paleo literature -- how-to books that are mostly how-to-undo books.”
