Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves
Nicola Twilley | June 2024
In June 2024, Gastropod co-host Nicky published this book, which we discussed in our episode The Birth of Cool: How Refrigeration Changed Everything.
Frostbite takes readers on a tour of the cold chain from farm to fridge, visiting off-the-beaten-path landmarks such as Missouri’s subterranean cheese caves, the banana-ripening rooms of New York City, and the vast refrigerated tanks that store the nation’s orange juice reserves. A deeply researched and reported, original, and entertaining dive into the most important invention in the history of food and drink, Frostbite makes the case for a recalibration of our relationship with the fridge—and how our future might depend on it.
In the developed world, we’ve reaped the benefits of refrigeration for more than a century, but the costs are catching up with us. We’ve eroded our connection to our food and redefined what “fresh” means. More important, refrigeration is one of the leading contributors to climate change. As the developing world races to build a US-style cold chain, Nicky asks: Can we reduce our dependence on refrigeration? Should we?
Today, nearly three-quarters of everything on the average American plate is processed, shipped, stored, and sold under refrigeration. It’s impossible to make sense of our food system without understanding the all-but-invisible network of thermal control that underpins it. Nicky’s eye-opening book is the first to reveal the transformative impact refrigeration has had on our health and our guts; our farms, tables, kitchens, and cities; global economics and politics; and even our environment.

Until Proven Safe: The History and Future of Quarantine
Nicola Twilley and Geoff Manaugh | July 2021
In July 2021, Gastropod co-host Nicky and her husband Geoff published this co-authored book, which inspired this episode: Chocpocalypse Now! Quarantine and the Future of Food.
Until Proven Safe tracks the history and future of quarantine around the globe, chasing the story of emergency isolation through time and space—from crumbling Mediterranean lazarettos built to contain the Black Death to an experimental Ebola unit in London, from the hallways of the CDC to closed-door simulations where pharmaceutical execs and epidemiologists prepare for pandemics yet to come.
But the story of quarantine ranges far beyond the history of medical isolation. The authors tour a nuclear-waste isolation facility beneath the New Mexican desert, see plants stricken with a disease that threatens the world’s wheat supply, and meet NASA’s Planetary Protection Officer, tasked with saving Earth from extraterrestrial infections.
Geoff Manaugh and Nicola Twilley have been researching quarantine since long before the COVID-19 pandemic. With Until Proven Safe, they bring us a book as compelling as it is definitive, an up-to-the-minute investigation of the interplay of forces—biological, political, technological—that shape our modern world. It is a thrillingly reported, thought-provoking exploration of the meaning of freedom, governance, and mutual responsibility.
Until Proven Safe helps us make sense of our new reality. Buy it here.
Tracking and Increasing the Representation of Diverse Voices: A Report and Findings
Gastropod | September 2020
In October 2018, with the support of the Alfred P. Sloan Foundation, Gastropod launched a ground-breaking and ambitious diversity initiative. This report is, to our knowledge, the first time a podcast has publicly and transparently demonstrated the ways in which they work to ensure their guests represent a wide diversity of voices.
In it, we share the novel metric and method we developed to quantify that representation—a way of measuring our performance against our real goal, which is increasing the diversity of voices heard as opposed to simply the diversity of guests on the show. We also share our surveys and tools, our strategies for finding diverse sources, and our lessons learned, in order to help other radio shows and podcasts. We hope this report contributes to a dialogue we think is essential: how can podcasts help combat pervasive bias against women and Black, Indigenous, and People of Color (BIPOC) in our society?
