The next time you open your fridge, take a second to behold the miracles inside of it: Raspberries from California, butter from New Zealand, steak from Nebraska. None of that would have been remotely possible before the creation of the cold chain. The cold chain is the name for the end-to-end refrigeration of our food from farm to truck to warehouse to grocery store and ultimately to our fridges at home. And it's one of the great achievements of the modern world. On today's show, Nicola Twilley, food journalist and author of Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves, tells us the story of how our world got cold, and what that's meant for the economy.  We'll hear about two pioneers of cold: The cheapskate meat baron Gustavus Swift, and the train-hopping chemist Polly Pennington. And we'll take a look at whether all this refrigeration might have created some new problems. Subscribe to Planet Money+Listen free: Apple Podcasts, Spotify, the NPR app or anywhere you get podcasts.Facebook / Instagram / TikTok / Our weekly Newsletter.Today's episode of Planet Money was hosted by Nick Fountain and Alexi Horowitz-Ghazi.

In the early 1900s, people didn't trust refrigerated food. Fruits and vegetables, cuts of meat… these things are supposed to decay, right? As Nicola Twilley writes, “What kind of unnatural technology could deliver a two-year old chicken carcass that still looked as though it was slaughtered yesterday?”But just a few decades later, Americans have done a full one-eighty. Livestock can be slaughtered thousands of miles away, and taste just as good (or better) by the time it hits your plate.  Apples can be stored for over a year without any noticeable change. A network called the “cold-chain” criss-crosses the country, and at home our refrigerators are fooling us into thinking we waste less food than we actually do. Today, refrigeration has reshaped what we eat, how we cook it, and even warped our very definition of what is and isn't “fresh.” Featuring Nicola Twilley.For full credits and transcript, visit outsideinradio.org. SUPPORTOutside/In is made possible with listener support.

Farmers markets are a great provisioning option for cruisers. Produce is often fresher and less bruised. And if it hasn't been refrigerated, it will keep longer on your boat.  Summary Farmers markets are a great provisioning option for cruisers. Produce is often fresher and less bruised. And if it hasn'tbeen refrigerated, it will keep longer on your boat.  As we head into peak harvest season in many places, count on farmers markets for provisioning. Why? Goods are usually fresher, picked locally, and not trucked across the country. Produce is often unrefrigerated, making it key for storage aboard. Finally, it's usually less bruised, offering a longer shelf life and better flavor. And it's not only produce you'll find. Look for fresh eggs, homemade baked goods, cheese, and meat with fewer preservatives (although they will last less long). Best of all, you can ask vendors questions about what they're selling. You can find farmers markets around the world. Every town has its specialties. Ask everyone in your local cruising network for locations. And, if you're sailing the ICW, you'll find farmers markets near many marinas and anchorages. Oneof the largest is the West Palm Beach GreenMarket, which runs from October through April. Check the show notes for a link to a list of markets located along the ICW.

We eat apples in the summer and enjoy bananas in the winter. When we do this, we go against the natural order of life which is towards death and decay. What gives? This week, Latif Nasser spoke with Nicola Twilley, the author of Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves. Twilley spent over a decade reporting about how we keep food alive as it makes its way from the farm to our table. This conversation explores the science of cold, how fruits hold a secret to eternal youth, and how the salad bag, of all things, is our local grocery store's unsung hero.Special thanks to Jim Lugg and Jeff WoosterEPISODE CREDITS: Reported by Latif Nasser and Nicola Twilleywith help from Maria Paz GutierrezProduced by Maria Paz GutierrezOriginal music from Jeremy BloomSound design contributed by Jeremy Bloomwith mixing help from Arianne WackFact-checking by Emily Krieger and Edited by Alex NeasonEPISODE CITATIONS:Articles  New Yorker Article - How the Fridge Changed Flavor (https://zpr.io/32TuSmAc2HbQ)by Nicola TwilleyNew Yorker Article - Africa's Cold Rush and the Promise of Refrigeration (https://zpr.io/3g9VdgKMAiHf) by Nicola TwilleyBooks Frostbite (https://zpr.io/Mg3Q7JCBvcAg) by Nicola TwilleySignup for our newsletter!!
