In the past decade, archaeologists have applied new techniques for analyzing the teeth of prehistoric humans. Finding: Near-universal presence of wild grain/legume residues, going back more than 100,000 years. In other words: the ubiquitous presence of these foods during human evolutionary history.

Does eating like our ancestors mean eschewing grains and legumes? The opposite would seem to be true.

Incidentally, this also helps us to make sense of the transition by humans to agriculture: it was not an abrupt revolution in foodways but an intensification of dietary patterns in part already in place during the upper Paleolithic. This helps us to understand the neolithic revolution not as an inexplicable, radical break but something much more understandable from the viewpoint of those who undertook it.

And thank you for coming to my TED Talk.
