800 million people currently go to sleep hungry, but 1 in 4 of us are predicted to be obese by 2035. Securing access to food for everyone and making it sustainable for our planet are some of our greatest challenges. Professor Johannes le Coutre, the leader of UNSW’s food program, and Katherine Samaras, Laboratory Head of the Garvan Institute and specialising in diabetes and obesity prevention, join STEMM journalist Neil Martin to talk about potential solutions for keeping us fed and the planet happy. They discuss why looking back to old agricultural techniques could hold some answers, and how diabetes drug Ozempic isn’t the fix for over-eating.
