Summary

This week we have two interviews from the annual meeting of AAAS in Washington D.C.: one on the history of food and one about our own perceptions of food and food waste.  First up, host Sarah Crespi talks with Christina Warinner from the Max Planck Institute for the Science of Human History in Jena, Germany, about the history of dairying. When did people first start to milk animals and where? It turns out, the spread of human genetic adaptations for drinking milk do not closely correspond to the history of consuming milk from animals. Instead, evidence from ancient dental plaque suggests people from all over the world developed different ways of chugging milk—not all of them genetic. Next, Host Meagan Cantwell speaks with Sheril Kirshenbaum, co-director of the Michigan State University Food Literacy and Engagement Poll, about the public’s perception of food waste. Do most people try to conserve food and produce less waste? Better insight into the point of view of consumers may help keep billions of kilograms of food from being discarded every year in the United States. This week’s episode was edited by Podigy.
