So he's trying to figure out what these very poor people are going to do as they ascend to middle class status. What are they going to buy so that he can invest in those companies and make money. And the problem is we know that as people get richer, they change what they eat. But when you ask them what they're going to eat, they're like, oh no, no, no, I would still eat the same things. I wouldn't change anything.
Ricky Mulvey
Foreign. I'm Ricky Mulvey and that's Nicola Twilley, the author of How Refrigeration Changed Our Food, Our Planet and Ourselves. She's also the co host of Gastropod. We played a part of my conversation with Twilly on Friday's show. It's about how the technology of refrigeration followed the Gartner hype cycle because its history has some lessons for investors today. If you haven't listened that first part, I recommend you listen when you can. But if you haven't, today's show will make sense in and of itself. I chat with Twillie about her experience inside the cold chain, what it's like working in refrigerated warehouses. We also talk about why ice cream is especially tricky to handle and how an emerging markets investor made money by checking the fridge. Been following the artificial cryosphere for, for a while now. And it's something that we come in contact with in a very small form. Maybe our refrigerators at home or the frozen food section at a Walmart. But you've called it the third Pole. Can you give, can you give us a scope of the artificial cryosphere?
Nicola Twilley
Yeah, I ended up calling it the artificial cryosphere to distinguish it from Earth's natural cryosphere. So that's the ice caps at the Antarctic and the Arctic and the glaciers that are increasingly shrinking. And the irony of course, is that as the natural cryosphere is shrinking, the artificial cryosphere, the places we've built for our food to live in, that's growing, it's already at over 5 billion cubic feet that's huge. But it grew 20% between 2018 and 2020. There's a global cold rush under way. So it's, it's expanding at a extremely rapid rate, kind of as our natural cryosphere shrinks. And I'm not just talking like you say, about your home fridge or the, the walk in at the restaurant or the freezer aisle at the, at the supermarket. I'm talking about these gigantic refrigerated warehouses and juice tanks and avocado ripening rooms and meat lockers that most of us, even the most committed foodies and chefs will never have seen.
Ricky Mulvey
You saw the inside of Americold, which is, it's a real estate investment trust that is heavily involved in the cold chain. What was it like, you know, in your day working there? What's it like to work inside of the cold chain?
Nicola Twilley
I mean, this is going to make me sound stupid, but it's really cold. It's hard to exaggerate how cold it is. Obviously, I figured it would be cold. They kit you out. I was working shifts in americold locations in Southern California. So you show up, it's this gorgeous day outside as it is in Southern California. Then you go in, they kit you up with refrigerator gear, which is this special company that makes equipment for people who work in refrigerated warehouses. It's called iron tough minus 50. And it's supposed to keep you warm down to that temperature. And it, it's pretty great stuff. But let me tell you, once your toes and your nose and your fingers get cold, it's, it's all over. You're really cold. I was told that, you know, a lot of folks, they do their first shift, they leave at lunchtime, they just, they're just not okay with being that cold. But yeah, I. Americold is the second largest refrigerated warehouse provider in the world. They're a global company. And I wanted to get a sense of what it like to work and be in these spaces that we have built for our food to live in, but we so rarely see inside. And so the way to do that is to work alongside folks and get a sense for the rhythm, what goes in, what comes out, what it's actually like to work there.
Ricky Mulvey
What did you learn about the workers who stayed there longer than lunchtime? It seems like it takes a special type of person to work for years in a refrigerated warehouse.
Nicola Twilley
Yeah, my co workers were really the best part of working in the cold. You do have to be a pretty tough individual. A lot of Them end up saying, oh, they love the cold. It keeps them young. I guessed one of them as being a full 10 years younger than he actually was. And he was like, see, it's the cold. It preserves me just like it preserves your milk. So they, it's interesting. It's. It's a terrible place to work if you wear glasses, because your glasses are constantly steaming up from the condensation. As you change, you come out of the cold room, into the cold room, into the freezer, out of the freezer. If you have a mustache, you will grow icicles off that. So also a bad idea. Everyone gets sick. They all warned me about that. Colds, sneezes, something called freezer flu. And there is actually a scientific reason for that. You actually are more likely to catch a cold in the cold. It's a mechanism that scientists have only just discovered. There are these little bubbles in our noses that prevent the cold virus from sort of settling and taking hold. And you make fewer of those bubbles in the cold. So if you work in the cold, you're more likely to get sick. So that was kind of interesting. It's a. I mean, you have to, you have to be sort of slow, steady, and patient. Because one of the things that's interesting is, you know, the way cold preserves food is it slows down the metabolism of the things that are trying to eat our food. So all the bacteria and the fungi that are, that are trying to eat our food before we can, they, they, they have their metabolism slowed down in the cold. Same with producers. It is breathing. It's a living thing, and it breathes more slowly in the cold, so it has more breaths before it dies. Hence it's preserved for longer. But the cold also slows humans down. So actually, however fast and sharp you think you are, I went into the cold storage warehouse with my type A personality thinking I was going to ace this. And you just. They call it cold stupid. You just operate more slowly in the cold. Everything does, actually. You have to have special computers, special equipment. You know, the. There are heaters on screens. The engine oil gets kind of clogged up and sticky, so things work less well. Everything just kind of goes a little slower in the cold. Which makes a cold warehouse one of the most dangerous working environments in America. It's warehouse work is already one of the more dangerous jobs. Add coal to that and it really is, it really is a dangerous and tough environment.
Ricky Mulvey
You mentioned ice cream as well. And one of the stories we saw earlier this year in the business world is that unilever spun off their ice cream division, which includes Ben and Ben and Jerry's. The cold. The. A cold chain is difficult enough to take care of, but is there anything unique about ice cream that makes it especially difficult to get through a cold chain into a freezer in a grocery store?
Nicola Twilley
Absolutely. Yeah. Ice cream is well known for being one of the trickiest items you can handle in the cold chain. And there's a few reasons for that. Okay? So first of all, for non premium brands, so for things like Turkey Hill or Breyers or things like that, a pint of ice cream is about half air. When you buy that ice cream, half of it is air. And that leads to a lot of logistical headaches because when you move that ice cream around the country, it goes up and it goes down. Or, you know, there are mountain ranges, the Rockies, the Sierra Nevadas, and what happens is at those higher elevations, air is thinner. And so you get something called overflow or shrinkage. And that's where, because the ice cream is 50% air, it will either collapse in on itself and pull away from the sides of the. Of the container or actually explode out and overflow and sort of have this kind of mushroom puffy top because the air has expanded. So you actually can't truck ice cream from Washington state to Georgia because of the rock. That's one thing. The other thing with a premium brand like Ben and Jerry's is because you aren't using the kind of stabilizers and emulsifiers that you might use in a less expensive brand. You are really relying on cold chain integrity to keep that ice cream from crystallizing. Now, we've all had that experience when you keep a pint of ice cream in your freezer for too long, and it gets kind of crystalline around the top and the texture is gone, and it's just not as nice anymore. That's because your home freezer doesn't maintain these, the absolute perfect temperature at all times. It lets that slight melt and refreeze and slight variations in temperature that will cause those crystals to form. And if those crystals form, your ice cream is ruined. So for. For someone like Unilever trying to keep Ben and Jerry's absolutely smooth, creamy, dense, delicious, no crystals as they ship it around with none of the chemical aids that you might use the stabilizers that would help, I can see why they got out of that business, because, you know, I saw it even myself in working at americold. You pull a pallet, you leave it on the loading dock. Well, the loading dock is at a Different temperature than the freezer. Then it goes into the, the truck. But while the truck is being loaded, well that's, that might be a two hour process and the temperature is fluctuating too. So ice cream really needs white glove treatment and that makes it a headache.
Ricky Mulvey
I think my main takeaway from that answer is that ice cream is 50% air, therefore it is healthier than I, than I think. You've given me permission for a treat after this interview.
Nicola Twilley
You don't need permission. Treat yourself. Do it.
Ricky Mulvey
There we go.
Nicola Twilley
Ice cream is one of the great gifts of the cold chain.
Ricky Mulvey
The cold chain is also allowed essentially the rise of Walmart's grocery business, which you point out is 15% of all perishables sold in the United States. We often it makes intuitive sense that Walmart's produce is cheaper than Whole Foods produce. Some of that has to do with I'm sure the cost of having a huge supercenter versus smaller grocery stores and maybe more expensive rent areas. But how has the cold chain allowed Walmart's rise in essentially domination in grocery in the United States?
Nicola Twilley
Yeah, this was really interesting to me. It was explained to me by a logistics expert called Mark Wolfrat and he pointed out that when Walmart decided to go into the perishables business, which was surprisingly recently, they hired a bunch of grocery store people and they figured out how to do it. And the key constraint is that if you are stocking your own stores with perishable goods, you need to have them within 250 miles of a distribution center, your own distribution center to keep costs down. And that way you can have the truck load up in the morning at the, at the distribution center, get out to the store, drop off at the store, come back 250 miles. Is the, the sort of limit for doing, for stocking a store efficiently. Now Walmart very deliberately planned its rollout of grocery in its stores so that it kind of happened in these 250 mile radii. It just said, okay, we're going to start here at this store, this, this kind of circle of stores and build a distribution center here that can supply this circle. We'll sort of leap out from there. So, so at no time was it trying to stock stores from distribution centers that were further away or subcontracting out that distribution. So it kept tight control over that and that is what enabled it to be so efficient. Somewhere like Whole Foods, it doesn't have enough stores within a 250 mile radius to justify the cost of having its own distribution center. So it has to outsource that. And when you outsource it, well, you're not getting the efficiencies, first of all. Second of all, you're paying someone else's overhead. And second of all, you're also not at the top of the list. So if there's a delay getting a truck out that might hit your store. So Walmart, because it sort of did this very sort of tight logistical planning around the limitations of the cold chain, it has managed to have those super low prices on perishable producer that, you know, Whole Foods been in the business much longer of selling groceries, but doesn't have the density of stores within that 250 mile radius to make it worth.
Ricky Mulvey
Building their own facilities and cold chain.
Nicola Twilley
Exactly.
Ricky Mulvey
We're now at a place where refrigeration is thankfully for, for us eaters, a mature business. But it continues to grow in the cryosphere comes at a cost because the first law of thermodynamics, you can't, you can only transfer energy, you can't destroy it. Why does the cryosphere continue to grow, particularly in the United States, even though it's such a mature part of our economy?
Nicola Twilley
Yeah, this, there should be enough refrigerated space in the US for everybody. We have the most per person of, you know, of anyone in the world pretty much. But the issue is, and this is why there is such a lot of investment in refrigerated cold storage right now and such growth in the market, even in the US the issue is to do with location and type. So location, okay. With the expansion of the Panama Canal, for example, a lot of new refrigerated warehouses are being built along east coast ports. That's because now that the Panama Canal is being expanded, well, food shippers don't want to be dependent on west coast ports where you have more union presence and more environmental rules. And they can be hit with those. They want the opportunity to ship out of the east coast too. And so there's huge investment in South Carolina, North Carolina, Jacksonville, Florida. Those ports are all building a lot of refrigerated warehouse space. Also post pandemic, there has been a transition in American shopping habits. So this rise in delivery and on demand and things like get here and you know, the, the companies that are doing this kind of two hour grocery delivery service, they have to have distribution centers that can't be far out of town. So they're building, they're coming back into cities or peripheral areas and building new cold storage there to deal with this new demand. The other thing is The American labor force is increasingly saying, you know what, I don't want to work in the cold. And I sympathize having done that. And. Exactly. I am 100% on board with that sentiment. And so there's this rise in automated cold storages, and those are very different buildings. You can't just retrofit an existing cold storage to make it automated. The automated ones are several stories high. They're really cool. I went into one and they strapped me to this sort of the automated crane handle and I went swooping through the racks with this kind of. Inside the machine, they keep them deliberately low oxygen for fire prevention because they're too tall for sprinkler systems. So I was a little bit delirious anyway. And the whole thing was like the best theme park ride ever. But. But yeah. So that's why the, the, the amount of refrigerated space in the US is still expanding because of these shifts in, in logistics chains, in how Americans demand their food and in where Americans are willing to work.
Ricky Mulvey
I want to talk about some of the, the economics and investors in refrigeration. One person who I think would be particularly interesting to our audience is Tassos Stasopoulos. I think I got that right.
Nicola Twilley
You did.
Ricky Mulvey
He made money by looking in other people's fridges, particularly in India. How did Tassos invest based on looking inside people's fridges?
Nicola Twilley
Tassos runs an investment and an asset management firm based in London. And his whole investment strategy is based around looking in people's fridges. And he sort of rejects, you know, the, the normal benchmarks. He's like, oh, you know, The S&P 500 is for schmucks. Everyone can look at that. I go and look in fridges. And so what he does, the, the revelation came to him actually in India. He was trying to figure out here is a country that is. And his specialty, I should say, is emerging markets. This is where he goes, but. So he's trying to figure out what these very poor people are going to do as they ascend to middle class status, what are they going to buy so that he could invest in those companies and make money. And the problem is we know that as people get richer, they change what they eat. But when you ask them what they're going to eat, they're like, oh, no, no, no, I would, I would still eat the same things. I wouldn't change anything. I would send my kid to school and I would, you know, make sure, I don't know, my sister gets the medical treatment she needs. But they don't say, oh, I'm going to change my whole diet. And they don't know. And he realized, oh, if you look in the fridges of people who are one socioeconomic class ahead of them, you can see where an entire society will go. So now he does these huge ethnographic immersions. He's just come back from Indonesia, which is a very kind of exciting market for, for investors. Huge group of very young people poised on the cusp of becoming middle class. And he just spends hours sitting down having them talk through what's in their fridge. And he's developed this whole system for analyzing that. Okay, they're interested. He, for example, he told me, you know, in India you can start seeing, oh, they'll buy some processed dairy products. Dairy is huge in India because of the Hindu prohibition on eating a lot of meat. So dairy becomes sort of a key protein. And he noticed, ah, in the fridges of people 1 socioeconomic class up there were, there were yogurts, there were, there were butters, there were cheeses, there was processed dairy. That gives him an investment tip. He goes into that. It also tells him when to divest. So in China, which is another country that has refrigerated really recently, it's further along than India, but only by a little bit. And he used to invest in yum China there, which is the parent company of KFC and Taco Bell, all of those. And he, he went and looked at Chinese kind of upper middle class fridges and saw that actually those buckets of KFC had been replaced by things like green curry and probiotic yogurt. And they had moved on to this sort of next stage where it was about international foods and also health halo, things that were going to make you better somehow, you know, more worldly, more cosmopolitan, more healthy. So that, that international fast food was no longer a sort of status symbol. And so he divested. So this has proven a very successful investing strategy for him. And it's super, super fascinating process. I sort of tagged along remotely on his latest expedition and sort of sat there and watched as he has people sort of talk their way through their fridge. He does a really interesting exercise where he has them imagine their fridge in 10 years, which is really just people can't imagine their fridge in 10 years. They're talking about what they want right now. It tells you about their aspirations for right now. And he came back from Indonesia with, you know, a squeezable yogurt company that he thinks is a hot tip there.
Ricky Mulvey
You go, my fridge in 10 years will be significantly cleaner than it is today.
Nicola Twilley
You also learned about don't invest on that basis.
Ricky Mulvey
You learned a lot about fridge economics in the United States as well. And one, one thing that surprised me, and this is from William Rathji, is that economic stress changes how we eat in a more interesting way, which is that people buy more perishable foods and they also throw away more food when they're under economic stress. What do you think explains that phenomenon?
Nicola Twilley
It seems a bit counterintuitive, yet it's totally counterintuitive. And Bill Rathji was a garbologist. He sort of invented this discipline of sorting through people's trash and figuring out what, what it said about them. He was like, well, you know, we do it for ancient civilizations. We learn a ton from, you know, the midden heaps at archeological sites. So why not go and sort through the trash of, you know, middle class homeowners in Phoenix, Arizona, and managed to persuade a few graduate students to get the appropriate shots and come along with him and do it. And he's, he's the one who really quantified how much food Americans throw away, which is a huge amount. But also, as you say, this really counterintuitive finding that under economic stress people will buy more and throw away more. And I think it comes from a hoarding mentality. I mean, our fridges, there's something very primitive about our relationship with them. It is a sort of cave in which we store and that helps us feel safe and as if we are going to be okay and not hungry and not desperate. And so there is a hoarding mentality. There's an amazing UCLA study that took place over a decade here in la, looking at people's homes and focusing on their fridges and the level of sort of, yeah, just stockpiling that took place almost the more stress and the more chaos in the household, economic stress, but also just sort of time pressure stress and lifestyle stress. The more they tried to cram into their fridges and freezers to make sure they kind of weren't without. And you can see that come through really clearly in the transcripts. It's, it's sort of astonishing. People's fridges are so crammed full that they haven't been able to, you know, get ice out of their ice tray in, you know, a decade. But, but it, it's a sort of safety mechanism. And honestly, that's how fridges are marketed a lot of the time, as sort of, you have a mini supermarket at home, you're going to be okay. You have what you need, whatever it is, even if you haven't thought of it or yet, you're going to be fine. And so that reassurance is, is part of their promise, which is why they end up leading to so much food waste. Because, you know, a fridge does keep things fresh, but not forever. It's not this vault that you can put things in and you know, save for retirement, you have to eat it, eventually it will go bad. So yet people treat them as this sort of as a vault where they can put things in and those things will remain safe.
Ricky Mulvey
After reading frostbite, it did encourage me to clean out some of the yogurt I had in the back of my fridge. So you are having impact on readers. Nikki, I want to wrap up with, with just a few questions outside of the book. One really has nothing to do with what we've been talking about. But you study food, you know, the produce supply chain. One thing I'm constantly amazed by when I go to a grocery store, whether, whether it's Walmart or Whole Foods or Kroger, is that bananas are just so cheap. It's, they're like 59 cents a pound. It makes no sense to me. Why are bananas so cheap?
Nicola Twilley
Partly why bananas are so cheap is a loss leader. I mean bananas represent 10% of everything that goes across the supermarket scanner. A lot of is what I've been told by industry experts. So they are a key part of a supermarkets business. They are something that a lot of people buy. They are America's most popular fruit by a really large margin. And so keeping those prices down is going to attract customers also. I mean the banana of commerce is the ultimate refrigerated fruit. It's something I talk about in the story. It was really the first fruit to get the full commercial refrigerated treatment. And you get the United Fruit Company's great white fleet, you know, now chiquita bringing, bringing bananas under refrigeration. This tropical fruit that, you know, now Americans could enjoy for the first time. I will say it's possible it could become more expensive as those companies are now having to pay for what they did in Central America. I mean the term banana republic was coined because of the, the shenanigans, just to put it very mildly, of these banana companies in league with the CIA in Central America that have left them destabilized and with really poor governance and infrastructure. And that's increasingly, I mean there was a very recent court case in the news where you know, these companies are now being held accountable for that action and are having, are being fined. So ultimately, those bananas may reflect more of their real cost at the store. I don't know.
Ricky Mulvey
Are there any food trends or trends in refrigeration that you're particularly excited about? Interested in that you want to leave the listeners of Motley Fool Money with?
Nicola Twilley
Yeah, I'm really excited about alternatives to refrigeration and how much better our produce could taste. And this actually ties to another trend that I know you've talked about on the show, which is the rise of Ozempic and these GLP drugs. One of the things that's happening for folks who are on these drugs is that they have a much greater appreciation for produce. They want to eat produce. Suddenly a cucumber or a peach is more appealing than, you know, a deep fried potato chip or a, you know, I don't know, a General Tso's chicken. So that's fascinating for someone who is excited about the future of the cold chain because one of the areas where refrigeration really doesn't do that well is on delivering great produce. We all know how bad a grocery we all know how bad a grocery store tomato is. In the winter, it tastes of nothing and is as hard as baseball. That's a deliberate choice on the part of tomato growers to breed for something that can be stored and shipped under refrigeration. Same is true for apples. They're stored and shipped under refrigeration. And that is what the breeders breed for. Not flavor, not deliciousness. Now, if, and this is a big if, people start demanding more flavor in their produce, well, guess what? We might need better techniques for preserving our fruit and vegetables. And one of the stories I look at in the book is a company called Appeal, which is actually saying they've developed a coating made out of food waste. But in the way it's applied at this nanoscale, it sort of self assembles into a coating that restricts the amount of oxygen and carbon dioxide and moisture going in and out of the fruit in such a way that it gives you the same shelf life as refrigeration, but at room temperature. And it preserves the good things, the flavor molecules, the nutrients in your produce, better than refrigeration. Now, if we could have this appeal coated produce in our stores tasting better with more of the nutrients we want and it didn't have to be refrigerated, that could be a huge win win.

Motley Fool Money Podcast Summary: "The Global Cold Rush"
Release Date: June 30, 2024
Hosts: Dylan Lewis, Ricky Mulvey, and Mary Long
Guest: Nicola Twilley, Author of How Refrigeration Changed Our Food, Our Planet and Ourselves and Co-host of Gastropod
In this episode of Motley Fool Money, host Ricky Mulvey engages in an enlightening conversation with Nicola Twilley, delving deep into the expansive world of refrigeration and its profound impact on our global economy, food supply chains, and investment opportunities. Titled "The Global Cold Rush," the episode uncovers the intricate dynamics of the artificial cryosphere, the challenges of maintaining perishable goods, and innovative investment strategies inspired by everyday household behaviors.
Nicola Twilley introduces the concept of the artificial cryosphere, distinguishing it from Earth's natural cryosphere, which includes ice caps, glaciers, and polar regions. She highlights the rapid expansion of artificial cold storage facilities, noting that "it's already at over 5 billion cubic feet and grew 20% between 2018 and 2020" ([02:23] Twilley). This surge occurs concurrently with the shrinking of the natural cryosphere, underscoring a significant shift in how humanity preserves and distributes food.
Twilley shares her firsthand experience working in Americold, the second-largest refrigerated warehouse provider globally. She vividly describes the extreme cold conditions, stating, "It's really cold. Once your toes and your nose and your fingers get cold, it's all over" ([03:50] Twilley). Despite the harsh environment, she emphasizes the camaraderie among workers, saying, "My co-workers were really the best part of working in the cold" ([05:32] Twilley). However, she also highlights the physical and logistical challenges, including the difficulty for those who wear glasses or grow facial hair, and the increased likelihood of getting sick due to lower body temperatures affecting the immune response.
A significant portion of the discussion centers on ice cream's unique challenges within the cold chain. Twilley explains, "Ice cream is well known for being one of the trickiest items you can handle in the cold chain" ([08:48] Twilley). She breaks down the complexities:
Air Content: Non-premium brands like Breyers contain about 50% air, leading to logistical issues such as overflow or shrinkage during transportation, especially over varying elevations.
Premium Brands: Companies like Ben & Jerry's avoid stabilizers and emulsifiers, relying solely on cold chain integrity to prevent crystallization. Any temperature fluctuation can ruin the product's texture, making transportation delicate and expensive.
These factors contributed to Unilever's decision to spin off its ice cream division, recognizing the high costs and complexities involved in maintaining product quality.
Twilley and Mulvey explore how the cold chain has been pivotal in Walmart's rise to grocery dominance in the United States. Twilley explains, "When Walmart decided to go into the perishables business, they hired grocery store experts and meticulously planned their distribution strategy" ([12:34] Twilley). By establishing distribution centers within a 250-mile radius of their stores, Walmart ensures efficient stocking and minimizes costs. This strategic localization contrasts with competitors like Whole Foods, which cannot achieve the same efficiency due to fewer stores within the critical distribution radius, leading them to outsource and incur higher costs.
Despite refrigeration being a mature industry, the artificial cryosphere continues to grow. Twilley attributes this to several factors:
Geographical Expansion: The Panama Canal expansion has spurred new refrigerated warehouses along East Coast ports (e.g., South Carolina, North Carolina, Florida) to reduce dependency on West Coast ports affected by stricter regulations.
E-commerce Growth: The rise in on-demand grocery delivery services necessitates more localized distribution centers to meet the demand for rapid delivery times.
Labor Challenges: With fewer individuals willing to work in cold environments, there's a shift towards automation. Twilley describes automated cold storage facilities as "several stories high" with advanced systems that replace human labor, albeit introducing new technological complexities ([15:31] Twilley).
These trends ensure that the artificial cryosphere remains a dynamic and growing segment of the global economy.
A standout segment features Twilley discussing Tassos Stasopoulos, an investor who leverages insights from household fridges to inform his investment decisions. Twilley explains, "Tassos runs an investment firm based in London, and his whole investment strategy is based around looking in people's fridges" ([18:30] Twilley). By analyzing the contents of fridges in emerging markets like India and Indonesia, Stasopoulos identifies rising consumer trends as populations ascend to middle-class status. For instance:
In India, the presence of "yogurts, butters, cheeses, and processed dairy" signals growing demand in the dairy sector.
In China, observing a shift from fast food buckets to "green curry and probiotic yogurt" indicated a move towards healthier and more international food preferences, prompting Stasopoulos to divest from companies like Yum China.
This ethnographic investment approach provides a unique lens for predicting market shifts based on tangible consumer behaviors.
Twilley and Mulvey delve into research by William Rathji, a garbologist who studies food waste through trash analysis. Twilley notes, "Under economic stress, people buy more perishable foods and throw away more food" ([23:24] Twilley). This counterintuitive behavior is attributed to a hoarding mentality, where individuals stockpile food as a safety mechanism against scarcity and uncertainty. A decade-long UCLA study corroborates this, revealing that households under economic or lifestyle stress tend to "cram their fridges and freezers," leading to increased food waste as stored items eventually spoil ([23:24] Twilley).
Addressing a seemingly simple question, Twilley explains why bananas remain one of the cheapest fruits in grocery stores. She states, "Bananas are a loss leader, representing 10% of everything that goes across the supermarket scanner" ([26:47] Twilley). As America's most popular fruit, maintaining low prices attracts customers and stimulates overall store traffic. Additionally, the historical commercial refrigeration of bananas by companies like the United Fruit Company revolutionized their accessibility and affordability. However, Twilley hints at potential future price increases due to legal and ethical repercussions faced by banana-exporting companies for past exploitative practices in Central America ([26:47] Twilley).
Looking ahead, Twilley expresses excitement about innovations that could replace traditional refrigeration while enhancing produce quality. She highlights companies like Appeal, which has developed a nanoscale coating from food waste materials. This coating regulates the exchange of oxygen, carbon dioxide, and moisture, effectively preserving produce at room temperature without sacrificing flavor or nutrients. Such advancements could lead to "better-tasting and more nutritious produce" while reducing dependence on energy-intensive refrigeration systems ([28:45] Twilley).
Additionally, Twilley connects this to the rise of GLP drugs like Ozempic, which increase consumer appreciation for fresh, flavorful produce. This shift in consumer demand could drive further innovation in the refrigeration and produce industries, aligning better with health and taste preferences ([28:45] Twilley).
The episode concludes with Twilley's recommendation of her book, "Frostbite," and her podcast, Gastro Pod, both of which offer deeper insights into the intersections of food, technology, and society. Mulvey emphasizes the episode's value in understanding the global cold rush and its significant implications for investors and consumers alike.
