So, you’re at the dentist office. While sitting in the waiting room, you pick up one of the many magazines. On the cover, is a title heralding a new dietary trend; the Paleo Diet. It may read “Eat like a Caveman” or “Paleo diet 101”. We see such titles everywhere as the paleo diet has gained enormous popularity in the western world. Often boasting staggering, stupendous, incredible health benefits, the paleo diet attempts to return us to the food our early ancestors consumed. However, many of the paleo diets we see in books and magazines are only loosely based on actual hominin diets. But, how are these paleo diets compiled when the generation they refer to has been gone for a few million years? Well, paleoanthropologists have been able to delve into the hominin diet by observing dental adaptations left behind by our early ancestors, documenting and cataloging information on early hominin diet.
