A few weeks ago, I made the point that even though we may not have access to our paleolithic ancestors’ (yes, all of them) food journals, and even though there were many different paleolithic diets depending on climate, latitude, topography and other environmental contexts, the ancestral eating paradigm remains viable, helpful, and relevant to contemporary interests. That almost goes without saying, right? It’s kind of why we’re all here, reading this and other blogs, and asking the butcher for lamb tongues and goat spleens with straight faces. This stuff works.
But make no mistake: we may not know the day-to-day eating habits of our ancestors, but we know some things. And we can use what we know, drawing on several lines of evidence, to make some educated estimates.
