Food fanatic Stefan Gates and his intrepid Gastronuts go on another wild culinary adventure to discover the truth about how we eat, what we eat and where food comes from. Along the way, they indulge in harebrained experiments, crazy cooking and eat the world's weirdest food. The Gastronuts explore whether food can be art. They meet artists and photographers who use everything from chocolate and cheese to mackerel and macaroons to make art that is a feast for both the eyes and the stomach.
