In this final episode, Professors David Raubenheimer and Steve Simpson step back from the details of research to think about the big picture. We hear about how the Charles Perkins Centre's work is modelled on the biology of the human brain, and we learn of the connection between climate change, protein, infectious disease pandemics and our nutrition. Last, we talk about our individual and collective responsibility for creating the systems that harm our health.  Hosted by novelist Charlotte...

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...

Last time we looked at how animals' environments provide for their nutritional health. In this episode Professors David Raubenheimer and Steve Simpson step us through key evolutionary developments in human nutrition, from the first use of fire to the start of industrialised food production, and what each big change has meant for our bodies, our societies and our health. Hosted by novelist Charlotte Wood, the first writer-in-residence at the Charles Perkins Centre, University of Sydney. More...

Moving out of the lab and into the wild, Professors David Raubenheimer and Steve Simpson take a look at how animals' natural environments provide everything they need for a healthy diet. From chasing a single grasshopper through the Arizona desert to measuring the urine of wild Borneo orang-utans, David explains how carefully animals in the wild select what they eat, and why. And we hear about some of the risks taken by passionate scientists living among the animals for their...

In Episode 3 Professors Steve Simpson and David Raubenheimer take us through further experiments - this time on humans, fruit flies and mice - to discover that there's a difference between 'benign' and unhealthy obesity, and a tradeoff between longevity and reproduction when it comes to the amount of protein we eat. And we discover why when you're craving barbecue-flavoured chips, you should eat an egg instead.  Hosted by novelist Charlotte Wood, the first writer-in-residence at the Charles...

What drives our food preferences? In Episode 2 Professors Steve Simpson and David Raubenheimer explain their breakthrough discovery about what animals eat and why. They take us through some of their research with insects, spiders, cats, dogs, primates and humans, all leading to the 'protein leverage hypothesis' - the profound change in thinking about what drives our human appetites. Along the way we hear about the challenges of holding your nerve in overturning long-held scientific...

Are scientists born or made? In Episode 1 we hear about the early years of Professors Steve Simpson and David Raubenheimer, and their childhood investigations into the natural world. From Steve's high school reconstructions of a cow skeleton to David's childhood hypothesis about the harmfulness of bees, we see how two schoolboys grew into two world-renowned scientists. We learn of their meeting at Oxford University and the early experiments with locusts that led to their groundbreaking...
