This extended episode we’re learning about the four kinds of food processing and how each has changed our diets. Earlier, we learned of the five appetites driving human food preferences - but now Professors David Raubenheimer and Steve Simpson discuss an even more powerful craving. It's the appetite for profit, and it’s destroying the ability of many of us to keep ourselves healthy. As well, we learn about how and why protein needs change throughout our lives. Hosted by novelist Charlotte Wood, the first writer-in-residence at the Charles Perkins Centre, University of Sydney.
