    E281: Is ultra-processed food still food?
    Aug 28 2025
    Lots of talk these days about ultra-processed foods (UPFs). Along with confusion about what in the heck they are or what they're not, how bad they are for us, and what ought to be done about them. A landmark in the discussion of ultra-processed foods has been the publication of a book entitled Ultra-processed People, Why We Can't Stop Eating Food That Isn't Food. The author of that book, Dr. Chris van Tulleken, joins us today. Dr. van Tulleken is a physician and is professor of Infection and Global Health at University College London. He also has a PhD in molecular virology and is an award-winning broadcaster on the BBC. His book on Ultra-processed People is a bestseller. Interview Summary Chris, sometimes somebody comes along that takes a complicated topic and makes it accessible and understandable and brings it to lots of people. You're a very fine scientist and scholar and academic, but you also have that ability to communicate effectively with lots of people, which I very much admire. So, thanks for doing that, and thank you for joining us. Oh, Kelly, it's such a pleasure. You know, I begin some of my talks now with a clipping from the New York Times. And it's a picture of you and an interview you gave in 1995. So exactly three decades ago. And in this article, you just beautifully communicate everything that 30 years later I'm still saying. So, yeah. I wonder if communication, it's necessary, but insufficient. I think we are needing to think of other means to bring about change. I totally agree. Well, thank you by the way. And I hope I've learned something over those 30 years. Tell us, please, what are ultra-processed foods? People hear the term a lot, but I don't think a lot of people know exactly what it means. The most important thing to know, I think, is that it's not a casual term. It's not like 'junk food' or 'fast food.' It is a formal scientific definition. It's been used in hundreds of research studies. The definition is very long. It's 11 paragraphs long. And I would urge anyone who's really interested in this topic, go to the United Nations Food and Agricultural Organization website. You can type in NFAO Ultra and you'll get the full 11 paragraph definition. It's an incredibly sophisticated piece of science. But it boils down to if you as a consumer, someone listening to this podcast, want to know if the thing you are eating right now is ultra-processed, look at the ingredients list. If there are ingredients on that list that you do not normally find in a domestic kitchen like an emulsifier, a coloring, a flavoring, a non-nutritive sweetener, then that product will be ultra-processed. And it's a way of describing this huge range of foods that kind of has taken over the American and the British and in fact diets all over the world. How come the food companies put this stuff in the foods? And the reason I ask is in talks I give I'll show an ingredient list from a food that most people would recognize. And ask people if they can guess what the food is from the ingredient list. And almost nobody can. There are 35 things on the ingredient list. Sugar is in there, four different forms. And then there are all kinds of things that are hard to pronounce. There are lots of strange things in there. They get in there through loopholes and government regulation. Why are they there in the first place? So, when I started looking at this I also noticed this long list of fancy sounding ingredients. And even things like peanut butter will have palm oil and emulsifiers. Cream cheese will have xanthum gum and emulsifiers. And you think, well, wouldn't it just be cheaper to make your peanut butter out of peanuts. In fact, every ingredient is in there to make money in one of two ways. Either it drives down the cost of production or storage. If you imagine using a real strawberry in your strawberry ice cream. Strawberries are expensive. They're not always in season. They rot. You've got to have a whole supply chain. Why would you use a strawberry if you could use ethyl methylphenylglycidate and pink dye and it'll taste the same. It'll look great. You could then put in a little chunky bit of modified corn starch that'll be chewy if you get it in the right gel mix. And there you go. You've got strawberries and you haven't had to deal with strawberry farmers or any supply chain. It's just you just buy bags and bottles of white powder and liquids. The other way is to extend the shelf life. Strawberries as I say, or fresh food, real food - food we might call it rots on shelves. It decays very quickly. If you can store something at room temperature in a warehouse for months and months, that saves enormous amounts of money. So, one thing is production, but the other thing is the additives allow us to consume to excess or encourage us to consume ultra-processed food to excess. So, I interviewed a scientist who was a food industry development scientist. And they said, you know, most ultra-processed food would be gray ...

  • E280: Industry user fees could fix a food safety loophole for FDA

    E280: Industry user fees could fix a food safety loophole for FDA
    Aug 25 2025
    The Food and Drug Administration or FDA regulates roughly 78% of the US food supply. This includes packaged products, food additives, infant formula, ultra-processed foods, and lots more. However, an analysis by the Environmental Working Group found that 99% of new food ingredients enter our food supply through a legal loophole that skirts FDA oversight and seems, to me at least, to be incredibly risky. Today we're speaking with two authors of a recent legal and policy analysis published in the Journal Health Affairs. They explain what this loophole is and its risks and suggest a new user fee program to both strengthen the FDA's ability to regulate food ingredients and address growing concerns about food safety. Our guests are Jennifer Pomeranz Associate Professor of Public Health Policy and Management at New York University School of Global Public Health and Emily Broad, director of Harvard Law School Center for Health Law and Policy Innovation. Interview Summary So Jennifer, let's start with you, help our listeners understand the current situation with food ingredient oversight. And what is this legal loophole that allows food companies to add new ingredients without safety reviews. Sure. So, Congress passed the Food Additives Amendment in 1958, and the idea was to divide food additives and generally recognized as safe ingredients into two different categories. That's where the GRAS term comes from generally recognized as safe? ‘Generally Recognized As Safe’ is GRAS. But it circularly defines food additives as something that's not GRAS. So, there's not actually a definition of these two different types of substances. But the idea was that the food industry would be required to submit a pre-market, that means before it puts the ingredient into the marketplace, a pre-market petition to the FDA to review the safety. And then the FDA promulgates a regulation for safe use of a food additive. GRAS ingredients on the other hand, initially thought of as salt, pepper, vinegar, are things like that would just be allowed to enter the food supply without that pre-market petition. The problem is the food industry is the entity that decides which category to place each ingredient. There's no FDA guidance on which category they're supposed to ascribe to these ingredients. What has happened is that the food industry has now entered into the food supply an enormous amount of ingredients under what we call the GRAS loophole, which is allowing it to just bring it to the market without any FDA oversight or even knowledge of the ingredient. So, in essence, what we're having now is that the food industry polices itself on whether to submit this pre-market petition for a food additive or just include it in its products without any FDA knowledge. When you said ‘enormous number of such things,’ are we talking dozens, hundreds, thousands? Nobody knows, but the environmental working group did find that 99% of new ingredients are added through this loophole. And that's the concerning part. Well, you can look at some ultra-processed foods and they can have 30 or 40 ingredients on them. That's just one food. You can imagine that at across the food supply, how many things there are. And there are these chemicals that nobody can pronounce. You don't know what's going on, what they are, what they're all about. So, what you're saying is that the food industry decides to put these things in foods. There's some processing reason for putting them in. It's important that the public be protected against harmful ingredients. But the food industry decides what's okay to put in and what's not. Are they required to do any testing? Are there criteria for that kind of testing? Is there any sense that letting the industry police itself amounts to anything that protects the public good? Well, the criteria are supposed to be the same for GRAS or food additives. They're supposed to be meeting certain scientific criteria. But the problem with this is that for GRAS ingredients, they don't have to use published data and they can hold that scientific data to themselves. And you mentioned food labels, the ingredient list, right? That doesn't necessarily capture these ingredients. They use generic terms, corn oil, color additive, food additive whatever. And so, the actual ingredient itself is not necessarily listed on the ingredient list. There is no way to identify them and it's unknown whether they're actually doing the studies. They can engage in these, what are called GRAS panels, which are supposed to be experts that evaluate the science. But the problem is other studies have found that 100% of the people on these GRAS panels have financial conflicts of interest. Okay, so let me see if I have this right. I'm a food company. I develop a new additive to provide color or flavor or fragrance, or it's an emulsifier or something like that. I develop a chemical concoction that hasn't really been tested for human safety. I declare it safe. And the ...

  • E279: Feed Us With Trees - the surprising importance of nuts

    E279: Feed Us With Trees - the surprising importance of nuts
    Jul 31 2025
    Every day, with few exceptions, I eat a handful of nuts. Usually a combination of almonds, walnuts, pecans, cashews, and pistachios. And they taste good for sure. But I'm responding mainly to research showing that consumption of nuts is related to less chronic disease. In particular, eating nuts lowers levels of inflammation related to heart disease and diabetes, and may improve cholesterol levels among other benefits. So, I saw it as welcome news that someone has just published a book about nuts, all aspects of nuts, actually. Today we're joined by NPR, food Writer Elspeth Hay author of a new book called Feed Us with Trees- nuts, and The Future of Food. And I had no idea. Nuts were so interesting until I dove in a little bit. Elspeth has gathered stories from dozens of nut growers, scientists, indigenous knowledge keepers, researchers and food professionals. She writes that humans once grew their staple crops in forest gardens of perennial nuts, such as oaks, chestnuts, and hazelnuts in these species. Particularly important to the environment as well as to human wellbeing. Interview Summary Elspeth, thanks so much for joining us and for writing such an amazing book. Thank you so much for having me. And it sounds like you have the same habit as my dad. He makes sure to eat a little bit of mixed nuts every night, ever since I can remember for his health. Let’s start by having you describe your book. Tell us about Feed us with Trees. Why did you write it and what's it about? I wrote it because I've been reporting on food in the environment for a long time, a little more than 15 years. And I had never heard anyone mention anything about eating acorns until a few years ago. And someone sent me a TEDx talk by a woman in Greece named Marcie Mayer, and she said, you can eat acorns. And not only that, but they're a super food nutritionally, and one of humanity's oldest foods. And I live in this giant oak forest that's protected on Cape Cod as part of the Cape Cod National Seashore. And I had always seen this forest as a sort of impediment to local food production, right? There's all this land that can't be farmed. And all that time, it turns out there was food literally raining down on my roof, underfoot in my driveway, and I just wasn't equipped to see it. The stories that I had grown up with hadn't mentioned that. And so that was a real eyeopener for me and I just couldn't stop thinking about it and I kept researching. So, have you started consuming acorns? I have, yes. I've collected them the past probably five falls and, you know, oaks do something called masting. Some years they have a really big production and some years smaller production. Some years I've gotten more than others. But I have started processing them at home and experimenting with different ways of using the flour. And I've also ordered online acorn oil. There are actually three food products that you can make from acorns. You can make starch, which works just like corn starch or potato starch. Thickens things. You can make flour and with some species you can make oil. It's actually a pretty diverse crop. That's so interesting. You know, I have a series of oak trees right outside my window and I never thought that they might be producing food I could consume. It's so interesting to hear your history with that. Yes, I mean I had no idea. And it turns out that actually acorns are very similar to olives in the way that they need to be processed. They're very high in these compounds that are very bitter, called tannins, just like an olive. I had the experience once of going to Italy with my husband, and we saw this olive grove and we thought, oh cool. Olives growing right here. And we picked one off the tree and he put his in his mouth and immediately spat it out and said, oh, that's awful. Tannins are not something that we want to eat. They don't taste good, but obviously they haven't hampered the olives rise to glory in terms of a human food source. And Acorns need the same kind of processing. So, tannins are water soluble. You pull them out with water. You know, you always get olives in brine, right? And so Yes, just started learning more about how to work with them and then also more about our relationship with oak trees. And I started seeing them differently in that light too. Going from sort of the species that I'd always seen as natural and wild and better off without humans, to actually understanding that we have a really long history with oak trees and in some places, they actually really depend on us. So that was total game changer for me. There's more to the story than oaks and acorns. Tell us what you learned about the history of humans eating nuts like acorns, but also things like chestnuts and hazelnut. Yes, I was really surprised. At first, I thought, okay, this is going to be an isolated thing where some people in really hilly areas or areas that aren't good for row crops are eating these nuts as staple foods. But when I ...

  • E278: Here's how screen time affects our kids' eating, activity, and mental health

    E278: Here's how screen time affects our kids' eating, activity, and mental health
    Jul 15 2025
    Interview Summary So, you two, along with a number of other people in the field, wrote a chapter for a recently published book called The Handbook of Children and Screens. We discussed that book in an earlier podcast with its editors, Dmitri Christakis and Kris Perry, the executive director of the Children and Screens organization. And I'd like to emphasize to our listeners that the book can be downloaded at no cost. I'd like to read a quote if I may, from the chapter that the two of you wrote. 'Screen time continues to evolve with the advent of continuous and immersive video reels, voice activated assistance, social media influencers, augmented and virtual reality targeted advertising. Immersive worlds where children can virtually shop for food and beverages, cook or work in a fast-food outlet from a smartphone, a tablet, a computer, or an internet connected tv and more.' So as much as I follow the field, I still read that and I say, holy you know what. I mean that's just an absolutely alarming set of things that are coming at our children. And it really sounds like a tidal wave of digital sophistication that one could have never imagined even a short time ago. Amanda, let's start with you. Can you tell us a little bit more about these methods and how quickly they evolve and how much exposure children have? I think you're right, Kelly, that the world is changing fast. I've been looking at screen media for about 20 years now as a researcher. And in the earlier years, and Tom can attest to this as well, it was all about TV viewing. And you could ask parents how much time does your child spend watching TV? And they could say, well, they watch a couple shows every night and maybe a movie or two on the weekend, and they could come up with a pretty good estimate, 1, 2, 3 hours a day. Now, when we ask parents how much time their children spend with media, they have to stop and think, 'well, they're watching YouTube clips throughout the day. They're on their smartphone, their tablet, they're on social media, texting and playing all these different games.' It really becomes challenging to even get a grasp of the quantity of screen time let alone what kids are doing when they're using those screens. I will say for this book chapter, we found a really great review that summarized over 130 studies and found that kids are spending about three and a half or four hours a day using screens. Yet some of these studies are showing as high as seven or eight hours. I think it's probably under-reported because parents have a hard time really grasping how much time kids spend on screens. I've got a one-year-old and a five-year-old, and I've got some nieces and nephews and I'm constantly looking over their shoulder trying to figure out what games are they playing and where are they going online and what are they doing. Because this is changing really rapidly and we're trying to keep up with it and trying to make sure that screen time is a safe and perhaps healthy place to be. And that's really where a lot of our research is focused. I can only imagine how challenging it must be to work through that landscape. And because the technology advances way more quickly than the policies and legal landscape to control it, it really is pretty much whatever anybody wants to do, they do it and very little can be done about it. It's a really interesting picture, I know. We'll come back later and talk about what might be done about it. Tom, if you will help us understand the impact of all this. What are the effects on the diets of children and adolescents? I'm thinking particularly when Amanda was mentioning how many hours a day children are on it that three to four hours could be an underestimate of how much time they're spending. What did kids used to do with that time? I mean, if I think about when you and I were growing up, we did a lot of different things with that time. But what's it look like now? Well, that's one of the important questions that we don't really know a lot about because even experimental studies that I can talk about that look at reducing screen time have not been very good at being able to measure what else is going on or what substitutes for it. And so, a lot of the day we don't really know exactly what it's displacing and what happens when you reduce screen time. What replaces it? The assumption is that it's something that's more active than screen time. But, you know, it could be reading or homework or other sedentary behaviors that are more productive. But we really don't know. However, we do know that really the general consensus across all these studies that look at the relationship between screen time and nutrition is that the more time children spend using screens in general, the more calories they consume, the lower the nutritional quality of their diets and the greater their risk for obesity. A lot of these studies, as Amanda mentioned, were dominated by studies of television viewing, or looking at ...

  • E277: Food Fight - from plunder and profit to people and planet

    E277: Food Fight - from plunder and profit to people and planet
    Jun 27 2025
    Today we're talking with health and nutrition expert Dr. Stuart Gillespie, author of a new book entitled Food Fight: from Plunder and Profit to People and Planet. Using decades of research and insight gathered from around the world, Dr. Gillespie wants to reimagine our global food system and plot a way forward to a sustainable, equitable, and healthy food future - one where our food system isn't making us sick. Certainly not the case now. Over the course of his career, Dr. Gillespie has worked with the UN Standing Committee on Nutrition in Geneva with UNICEF in India and with the International Food Policy Research Institute, known as IFPRI, where he's led initiatives tackling the double burden of malnutrition and agriculture and health research. He holds a PhD in human nutrition from the London School of Hygiene and Tropical Medicine. Interview Summary So, you've really had a global view of the agriculture system, and this is captured in your book. And to give some context to our listeners, in your book, you describe the history of the global food system, how it's evolved into this system, sort of warped, if you will, into a mechanism that creates harm and it destroys more than it produces. That's a pretty bold statement. That it destroys more than it produces, given how much the agriculture around the world does produce. Tell us a bit more if you would. Yes, that statement actually emerged from recent work by the Food Systems Economic Commission. And they costed out the damage or the downstream harms generated by the global food system at around $15 trillion per year, which is 12% of GDP. And that manifests in various ways. Health harms or chronic disease. It also manifests in terms of climate crisis and risks and environmental harms, but also. Poverty of food system workers at the front line, if you like. And it's largely because we have a system that's anachronistic. It's a system that was built in a different time, in a different century for a different purpose. It was really started to come together after the second World War. To mass produce cheap calories to prevent famine, but also through the Green Revolution, as that was picking up with the overproduction of staples to use that strategically through food aid to buffer the West to certain extent from the spread of communism. And over time and over the last 50 years of neoliberal policies we've got a situation where food is less and less viewed as a human right, or a basic need. It's seen as a commodity and the system has become increasingly financialized. And there's a lot of evidence captured by a handful of transnationals, different ones at different points in the system from production to consumption. But in each case, they wield huge amounts of power. And that manifests in various ways. We have, I think a system that's anachronistic The point about it, and the problem we have, is that it's a system revolves around maximizing profit and the most profitable foods and products of those, which are actually the least healthy for us as individuals. And it's not a system that's designed to nourish us. It's a system designed to maximize profit. And we don't have a system that really aims to produce whole foods for people. We have a system that produces raw ingredients for industrial formulations to end up as ultra processed foods. We have a system that produces cattle feed and, and biofuels, and some whole foods. But it, you know, that it's so skewed now, and we see the evidence all around us that it manifests in all sorts of different ways. One in three people on the planet in some way malnourished. We have around 12 million adult deaths a year due to diet related chronic disease. And I followed that from colonial times that, that evolution and the way it operates and the way it moves across the world. And what is especially frightening, I think, is the speed at which this so-called nutrition transition or dietary transition is happening in lower income or middle income countries. We saw this happening over in the US and we saw it happening in the UK where I am. And then in Latin America, and then more Southeast Asia, then South Asia. Now, very much so in Sub-Saharan Africa where there is no regulation really, apart from perhaps South Africa. So that's long answer to your intro question. Let's dive into a couple of things that you brought up. First, the Green Revolution. So that's a term that many of our listeners will know and they'll understand what the Green Revolution is, but not everybody. Would you explain what that was and how it's had these effects throughout the food systems around the world? Yes, I mean around the, let's see, about 1950s, Norman Borlag, who was a crop breeder and his colleagues in Mexico discovered through crop breeding trials, a high yielding dwarf variety. But over time and working with different partners, including well in India as well, with the Swaminathan Foundation. And Swaminathan, for example, managed to ...

  • E276: Climate Change - A little less beef is part of the solution

    E276: Climate Change - A little less beef is part of the solution
    Jun 20 2025
    Interest and grave concern have been mounting over the impact of agriculture and the food choices we all make on the environment, particularly on climate change. With natural weather disasters occurring much more frequently and serious threats from warming of the atmosphere in general, it's natural to look for places to make change. One person who has thought a lot about this is our guest today, Dr. William Dietz of George Washington University. He's been a prominent voice in this space. Bill, you're one of the people in the field I respect most because our relationship goes back many years. Bill is professor and director of research and policy at the Global Food Institute at George Washington University. But especially pertinent to our discussion today is that Dr. Dietz was co-chair of the Lancet Commission on the global syndemic of obesity, under nutrition and climate change. Today, we'll focus on part of that discussion on beef in particular. Interview Summary Bill, let's start out with a basic question. What in the heck is a syndemic? A syndemic is a word that reflects the interaction of these three pandemics that we're facing. And those are obesity, under nutrition, and we've also called climate change a syndemic insofar as it affects human health. These three pandemics interact at both the biologic and social levels and have a synergistic adverse impact on each other. And they're driven by large scale social forces, which foster clustering and have a disparate impact on marginalized populations. Both in the developed and equally important, in the developing world. Here are a couple of examples of syndemics. So, increased greenhouse gases from high income countries reduce crop yields in the micronutrient content of crops, which in turn contribute to food insecurity and undernutrition in low and middle income countries. And eventually the reduction in crop yields and the micronutrient content of crops is going to affect high income countries. Beef production is a really important driver of the climate change, and we're a major contributor in terms of the US' contribution. And beef production drives both methane and nitrous oxide emissions, and in turn, the consumption of red and processed meat causes obesity, diabetes, colon cancer, and cardiovascular disease. And finally, obesity, stunting and nutrition insecurity occur in the same children and in the same population in low- and middle-income countries. Okay, so we'll come back to beef in a moment, but first, help us understand the importance of agriculture overall and our food choices in changing climate. Well, so I think we have to go back to where this, the increase in mean global surface temperatures began, in about 1950. Those temperatures have climbed in a linear fashion since then. And we're now approaching a key level of increase of 1.5 degrees centigrade. The increase in mean surface temperature is driven by increased greenhouse gases, and the US is particularly culpable in this respect. We're it's second only to China in terms of our greenhouse gas emissions. And on a per capita basis, we're in the top four with China, India, and Brazil and now the US. And in the US, agriculture contributes about 10% of greenhouse gas emissions, and about 30% of fossil fuels are responsible for greenhouse gas emissions. But when you look at the actual contribution of car use among the fossil fuel use, it's pretty close to the contribution of greenhouse gases from agriculture. The important point here is each one degree increase centigrade in air temperatures associated with a 7% increase in water vapor. And this is responsible for the major adverse weather events that we're seeing today in terms of increased frequency and severity of hurricanes, the droughts. And I learned a new term from the New York Times a couple of days ago from the science section, which is atmospheric thirst. I had trouble understanding how climate change would contribute to drought, but that same effect in terms of absorbing moisture that occurs and drives the adverse weather events also dries out the land. So increasingly there's increased need for water use, which is driven by atmospheric thirst. But that increase in air temperature and the increase in water vapor, is what really drives these storms. Because in the Pacific and in the Atlantic and the Gulf of Mexico, this increase in air temperature is associated with an increase in water temperature, which further drives the increase in the severity of these storms. Thanks for that background. Now let's get to beef. You and I were not long ago at the Healthy Eating Research conference. And you gave what I thought was a very compelling talk on beef. We'll talk in a minute about how much beef figures into this overall picture, but first, tell us how beef production affects both climate and health. And you mentioned nitrous oxide and methane, but how does this all work? Cattle production is a big driver of the release of methane. ...

  • E275: Against the Grain - A Plea for Regenerative Ag

    E275: Against the Grain - A Plea for Regenerative Ag
    Jun 16 2025
    I was at a professional meeting recently and I heard an inspiring and insightful and forward-looking talk by journalist and author Roger Thurow. Roger was a reporter for the Wall Street Journal for 30 years, 20 of them as a foreign correspondent based in Europe and Africa. Roger has written a number of books including one on world hunger and another what I thought was a particularly important book entitled The First 1000 Days, A Crucial Time for Mothers and Children and the World. Now comes a new book on farmers around the world and how they are coping with the unprecedented changes they face. It was hearing about his book that inspired me to invite Mr. Thurow to this podcast and thankfully he accepted. His new book is entitled Against the Grain: How Farmers Around the Globe are transforming Agriculture to Nourish the World and Heal the Planet. Interview Summary I really admire your work and have loved the new book and what I've read before. So, let's talk about something that you speak about: the wisdom of farmers. And you talk about their wisdom in the context of modern agriculture. What do you mean by that? Farmers of the world, particularly the small holder farmers, indigenous farmers, family farmers as we know them in this country, they're really bold and pioneering in what they're doing. And these farmers, kind of around the world as we go on this journey around the world in the book, they've seen their efforts to earn a living and feed nourish their families and communities turn against. So, while conforming to the orthodoxies of modern industrial agriculture practices: the monocropping, the increased use of fertilizers and pesticides and insecticide chemicals, the land expansion, at the expense of savannas, forest wetlands, biodiverse environments. In the face of this, they've really witnessed their lands degrading. Their soils depleting. Their waters dwindling. Their pollinators fleeing. Their biodiversity shrinking and becoming less diverse. Their rains becoming ever more mercurial., Their temperatures ever hotter. And their children and families and their communities becoming ever more hungry and malnourished. So, they've really seen the future of their own impacts on the environment, and then the impacts of changing climates, of more extreme weather conditions. They've really seen this future. They've experienced, lived it, and it's ugly what they see and what they've experienced on their farms. So, that's their wisdom, and they'll really tell us that it doesn't have to be that way if we listen. That such a future isn't inevitable. Because out of their desperation, you know, these farmers have begun farming against the grain. So, there's the title of the book Against the Grain of this modern agriculture orthodoxy to reconcile their roles as both food producers and nourishers of us all, and stewards in the land. They're pushing forward with practices like agroforestry, agroecology, regenerative agriculture, kind of whatever one calls it. Farming with nature instead of bending nature to their will, which is what we too often done and with kind of the larger modern industrial agriculture techniques. So, farming with nature as opposed to against it as they strive to both nourish us all and heal our planet. Give us a sense, if you will, about how important these small farmers are to the world's food supply? So how important are these? They're really important. Extremely vital for the global food chain, certainly for their own families and communities, and their countries. In a lot of places, say in Africa, in many of the countries, on the continent, it's the small holder farmers that are producing the majority of the food. In their communities and in their countries and across the continent. Still not enough. Africa then must become a substantial importer of food. But these small holder farmers are so key and the more success that they have in feeding their communities and families, the more success we all have then in this great goal of ending hunger and malnutrition. Equally important, these farmers are the stewards of the land. And they're on the front lines of these environmental challenges. The threats from the changing climate and more extreme weather conditions. They're the first impacted by it, but they also increasingly see, and that's what stories in the book are about, how they see that their own actions are then impacting their environment and their climates. And this is why they're so important for all of us is that they find themselves at the center of what I think is this great collision of humanities two supreme imperatives. One, nourish the world, so nourish us all. That's the one imperative. And then the other imperative, kind of colliding with that, is to preserve, protect, and heal our planet from the very actions of nourishing us. So, these are these two colliding forces. You know as I think we already know agriculture and land use activities are responsible for about a ...

    E274: Sweet and Deadly - Coca-Cola in the spotlight
    Jun 5 2025
    Recently I was asked to review a forthcoming book for American Scientist magazine. The book was entitled, Sweet and Deadly: How Coca-Cola Spreads Disinformation and Makes us Sick. I did the review, and now that the book has been published, I'm delighted that its author, Murray Carpenter, has agreed to join us. Mr. Carpenter is a journalist and author whose work has appeared in publications such as the New York Times, and the Washington Post, and has been featured in places like NPR's All Things Considered and Morning Edition. Interview Summary So, let's start with your career overall. Your journalism has covered a wide range of topics. But a major focus has been on what people consume. First, with your book Caffeinated and now with Sweet and Deadly. What brought you to this interest? My interest in caffeine is longstanding. Like many of us, I consume caffeine daily in the form of coffee. And I just felt like with caffeine, many of us don't really discuss the fact that it is a drug, and it is at least a mildly addictive drug. And so, I became fascinated with that enough to write a book. And that really led me directly in an organic fashion to this project. Because when I would discuss caffeine with people, mostly they just kind of wanted the cliff notes. Is my habit healthy? You know, how much caffeine should I take? And, and in short, I would tell them, you know, if you don't suffer from anxiety or insomnia and you're consuming your caffeine in a healthy beverage, well, that's fine. But, what I realized, of course, is that by volume, the caffeinated beverage people consume most of is sodas. And so that led me to thinking more about sodas because I got a lot of questions about the caffeine in sodas. And that led me to realize just the degree to which they are unhealthful. We've all known sodas not to be a health food, but I think that the degree to which they are not healthy surprised me. And that's what led me to this book. Yes, there's some very interesting themes aren't there with addiction and manipulation of ingredients in order to get people hooked on things. So let's talk about Coca-Cola a bit. Your book focuses on Coca-Cola. It's right there in the title. And certainly, they're giants in the beverage field. But are there other reasons that led you to focus on them? Other than that, the fact that they're the biggest? They're the biggest and really almost synonymous with sodas worldwide. I mean, many people don't say ‘I want a pop, I want a soda.’ They say, ‘I want a Coke.’ I quote a source as saying that. You know, what that means is you want a sugar sweetened beverage. And it's not just that they're the most successful at this game, and the biggest. But as I started doing this research, I realized that they have also been the most aggressive and the most successful at this sort of disinformation that's the focus of the book. At generating these health campaigns, these science disinformation campaigns, we should say. This is not to say Pepsi and Dr. Pepper have not been at this game as well, and often through the American Beverage Association. But it is to say that I think Coca-Cola has been the most sophisticated. The most invested in these campaigns. And I would argue the most successful. And so, I really think it's a league apart and that's why I wanted to focus on Coca-Cola. That makes good sense. So, in reading your book, I was struck by the sheer number of ways Coca-Cola protected their business interest at the expense of public health and also the degree to which it was coordinated and calculated. Let's take several examples of such activities and discuss exactly what the company has done. And I'd love your opinion on this. One thing you noted that Coke acted partly through other organizations, one of which you just mentioned, the American Beverage Association. There were others where there was sort of a false sense of scientific credibility. Can you explain more about what Coke did in this area? Yes, and one of the organizations that I think is perhaps the exemplar of this behavior is the International Life Sciences Institute. It's a very successful, very well-funded group that purports to you know, improve the health of people, worldwide. It was founded by a Coca-Cola staffer and has, you know, essentially carried water for Coke for years through a variety of direct and indirect ways. But so front groups, the successful use of front groups: and this is to say groups that don't immediately appear to be associated, say with Coca-Cola. If you hear the International Life Sciences Institute, no one immediately thinks Coca-Cola, except for people who study this a lot. The International Food Information Council, another very closely related front group. This is one of the ways that Coke has done its work is through the use of front groups. And some of them are sort of these more temporary front groups that they'll establish for specific campaigns. For example, to fight soda taxes in ...
