Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves

Nicola Twilley investigates the artificial cryosphere, a massive network of cold storage that sustains the modern global food supply. She documents how mechanical cooling disconnected human eating habits from the constraints of geography and seasons. The narrative explains the biological consequences of chilling produce, such as the loss of flavor in tomatoes and the extended shelf life of apples kept in low-oxygen environments for nearly a year. Twilley details the rise of the "cold chain" logistics system, which enables the transport of perishable goods across continents while fundamentally altering the chemical makeup of our diets and the energy consumption of our environment.

This book serves readers interested in the hidden infrastructure of industrial food systems and the link between technology and health. It appeals to home cooks who want to understand why supermarket ingredients differ from farm-fresh harvests and to environmentalists studying the carbon footprint of the cooling industry. Readers gain a technical understanding of refrigeration's impact on human gut microbiomes and the physical landscape. You finish with a clear perspective on how thermal control reshaped urban design and household behavior.
