E287: Food policy insights from government agency insider Jerold Mande

11/25/2025
In this episode, Kelly Brownell speaks with Jerold Mande, CEO of Nourish Science, adjunct professor at the Harvard School of Public Health, and former Deputy Undersecretary for Food Safety at the USDA. They discuss the alarming state of children's health in America, the challenges of combating poor nutrition, and the influence of the food industry on public policy. The conversation explores the parallels between the tobacco and food industries and proposes new strategies for ensuring children reach adulthood in good health. Mande emphasizes the need for radical changes in food policy and the role of public health in making these changes. Transcript So, you co-founded this organization along with Jerome Adams, Bill Frist and Thomas Grumbly, as we said, to ensure every child breaches age 18 at a healthy weight and in good metabolic health. That's a pretty tall order given the state of the health of youth today in America. But let's start by you telling us what inspired this mission and what does it look like to achieve this in today's food environment? I was trained in public health and also in nutrition and in my career, which has been largely in service of the public and government, I've been trying to advance those issues. And unfortunately over the arc of my career from when I started to now, particularly in nutrition and public health, it's just gotten so much worse. Indeed today Americans have the shortest lifespans by far. We're not just last among the wealthy countries, but we're a standard deviation last. But probably most alarming of all is how sick our children are. Children should not have a chronic disease. Yet in America maybe a third do. I did some work on tobacco at one point, at FDA. That was an enormous success. It was the leading cause of death. Children smoked at a higher rate, much like child chronic disease today. About a third of kids smoked. And we took that issue on, and today it's less than 2%. And so that shows that government can solve these problems. And since we did our tobacco work in the early '90s, I've changed my focus to nutrition and public health and trying to fix that. But we've still made so little progress. Give us a sense of how far from that goal we are. So, if the goal is to make every child reaching 18 at a healthy weight and in good metabolic health, what percentage of children reaching age 18 today might look like that? It's probably around a half or more, but we're not quite sure. We don't have good statistics. One of the challenges we face in nutrition is, unfortunately, the food industry or other industries lobby against funding research and data collection. And so, we're handicapped in that way. But we do know from the studies that CDC and others have done that about 20% of our children have obesity about a similar number have Type 2 diabetes or the precursors, pre-diabetes. You and I started off calling it adult-onset diabetes and they had to change that name to a Type 2 because it's becoming so common in kids. And then another disease, fatty liver disease, really unthinkable in kids. Something that the typical pediatrician would just never see. And yet in the last decade, children are the fastest growing group. I think we don't know an exact number, but today, at least a third, maybe as many as half of our children have a chronic disease. Particularly a food cause chronic disease, or the precursors that show they're on the way. I remember probably going back about 20 years, people started saying that we were seeing the first generation of American children that would lead shorter lives than our parents did. And what a terrible legacy to leave our children. Absolutely. And that's why we set that overarching goal of ensuring every child reaches age 18 in good metabolic health. And the reason we set that is in my experience in government, there's a phrase we all use - what gets measured gets done. And when I worked at FDA, when I worked at USDA, what caught my attention...

E286: How 'least cost diet' models fuel food security policy

11/3/2025
In this episode of the Leading Voices in Food podcast, host Norbert Wilson is joined by food and nutrition policy economists Will Masters and Parke Wilde from Tufts University's Friedman School of Nutrition, Science and Policy. The discussion centers around the concept of the least cost diet, a tool used to determine the minimum cost required to maintain a nutritionally adequate diet. The conversation delves into the global computational methods and policies related to least cost diets, the challenges of making these diets culturally relevant, and the implications for food policy in both the US and internationally. You will also hear about the lived experiences of people affected by these diets and the need for more comprehensive research to better reflect reality. Interview Summary I know you both have been working in this space around least cost diets for a while. So, let's really start off by just asking a question about what brought you into this work as researchers. Why study least cost diets? Will, let's start with you. I'm a very curious person and this was a puzzle. So, you know, people want health. They want healthy food. Of course, we spend a lot on healthcare and health services, but do seek health in our food. As a child growing up, you know, companies were marketing food as a source of health. And people who had more money would spend more for premium items that were seen as healthy. And in the 2010s for the first time, we had these quantified definitions of what a healthy diet was as we went from 'nutrients' to 'food groups,' from the original dietary guidelines pyramid to the MyPlate. And then internationally, the very first quantified definitions of healthful diets that would work anywhere in the world. And I was like, oh, wow. Is it actually expensive to eat a healthy diet? And how much does it cost? How does it differ by place location? How does it differ over time, seasons, and years? And I just thought it was a fascinating question. Great, thank you for that. Parke? There's a lot of policy importance on this, but part of the fun also of this particular topic is more than almost any that we work on, it's connected to things that we have to think about in our daily lives. So, as you're preparing and purchasing food for your family and you want it to be a healthy. And you want it to still be, you know, tasty enough to satisfy the kids. And it can't take too long because it has to fit into a busy life. So, this one does feel like it's got a personal connection. Thank you both for that. One of the things I heard is there was an availability of data. There was an opportunity that seems like it didn't exist before. Can you speak a little bit about that? Especially Will because you mentioned that point. Will: Yes. So, we have had food composition data identifying for typical items. A can of beans, or even a pizza. You know, what is the expected, on average quantity of each nutrient. But only recently have we had those on a very large scale for global items. Hundreds and hundreds of thousands of distinct items. And we had nutrient requirements, but only nutrient by nutrient, and the definition of a food group where you would want not only the nutrients, but also the phytochemicals, the attributes of food from its food matrix that make a vegetable different from just in a vitamin pill. And those came about in, as I mentioned, in the 2010s. And then there's the computational tools and the price observations that get captured. They've been written down on pads of paper, literally, and brought to a headquarters to compute inflation since the 1930s. But access to those in digitized form, only really in the 2000s and only really in the 2010s were we able to have program routines that would download millions and millions of price observations, match them to food composition data, match that food composition information to a healthy diet criterion, and then compute these least cost diets. Now we've computed millions...

E285: Gut instincts, food, and decision making

10/23/2025
The gut is in the news. It's really in the news. Catapulted there from exciting developments coming from laboratories all around the world. Links of gut health with overall health are now quite clear and surprising connections are being discovered between gut health and things like dementia and Alzheimer's. But how does the gut communicate with other parts of the body in ways that make it this important, and where does the brain figure into all this? Well, there's some interesting science going on in this topic, and a leading person in this area is Dr. Diego Bohorquez. Dr. Bohorquez is the associate professor of medicine, of molecular genetics and microbiology and of cell biology at the Duke University School of Medicine. Interview Transcript Diego, your bio shows that you blend work in nutritional biochemistry, gastrointestinal physiology, and sensory neurobiology. It took me a little time to figure out just what these things are, but what this represents, to be a little more serious, is a unique ability to understand that the different parts of the body, the gut and the brain in particular, interact a lot. And you're in a very good position to understand how that happens. Let's dive in with the kind of a basic question. What got you interested in this interaction of the gut with the brain and why care about it? Yes. Kelly, I think that that's all technicalese for saying that we are at the interface of food, the gut, and the brain. Apart from the fact that we are what we eat and if we truly believe that then food will be shaping us. Not only our body, but also like our belief systems, our societal systems, and so on and so forth. I don't think that that is anything new. However, what is new is the ability of the gut to guide our decision making. And it was interesting to hear in your introduction that now the gut is all in the news. In 2005 when I came to the United States, and I was at North Carolina State University, and I joined a graduate school. I remember taking a graduate course in physiology in 2007. And when the professor opened the session on gastrointestinal physiology, he said the gut is one of the most misunderstood and mysterious organs. It has almost as many neurons as the spinal cord, or more. But honestly, we don't give a lot of respect to the gut. We only think that it does some digestion and absorption, and we judge it more for the value of its products of digestion than what it does for the entire body. And fast forward almost 20 years later now, partly my laboratory and other laboratories that have entered this field since some of our discoveries started to emerge, it's very clearly showing that the gut not only has its own sensory system that is behind what we call gut feelings. The gut feelings are actually real. But it actually can influence our decision making. Like specifically, we have shown that our ability to choose sugars and consume sugars and feel sugars and choose them over sweeteners, it can be pinpointed to a specific set of cells in the intestine called neuropod cells and specific receptors in those cells. And the intestine is right after the stomach. And this is where these cells are exposed to the surface of the gut and detect the chemical composition of food to guide our decision making. Let's talk about that a little bit more. So, you've got this axis, or this means of communication between the gut and the brain going on. And let's talk about how it affects what we eat. You just alluded to the fact that it's pretty important. What does it tell us? What to eat, how much to eat? What we like to eat? When we're hungry, when we've had enough? How does this affect our eating? We are beginning to understand how much it affects this eating. And obviously we are departing from understanding, right? And an understanding is cognitive. In the 1500s is when the idea of 'we think therefore we are,' came online. And we needed to think things before we actually will understand them. But well...

E284: The Science of How Food Both Nourishes and Harms Us

10/16/2025
An avalanche of information besets us on what to eat. It comes from the news, from influencers of every ilk, from scientists, from government, and of course from the food companies. Super foods? Ultra-processed foods? How does one find a source of trust and make intelligent choices for both us as individuals and for the society as a whole. A new book helps in this quest, a book entitled Food Intelligence: the Science of How Food Both Nourishes and Harms Us. It is written by two highly credible and thoughtful people who join us today.Julia Belluz is a journalist and a contributing opinion writer for the New York Times. She reports on medicine, nutrition, and public health. She's been a Knight Science Journalism Fellow at MIT and holds a master's in science degree from the London School of Economics and Political Science. Dr. Kevin Hall trained as a physicist as best known for pioneering work on nutrition, including research he did as senior investigator and section chief at the National Institutes of Health. His work is highly regarded. He's won awards from the NIH, from the American Society of Nutrition, the Obesity Society and the American Physiological Society. Interview Transcript Thank you both very much for being with us. And not only for being with us, but writing such an interesting book. I was really eager to read it and there's a lot in there that people don't usually come across in their normal journeys through the nutrition world. So, Julia, start off if you wouldn't mind telling us what the impetus was for you and Kevin to do this book with everything else that's out there. Yes, so there's just, I think, an absolute avalanche of information as you say about nutrition and people making claims about how to optimize diet and how best to lose or manage weight. And I think what we both felt was missing from that conversation was a real examination of how do we know what we know and kind of foundational ideas in this space. You hear a lot about how to boost or speed up your metabolism, but people don't know what metabolism is anyway. You hear a lot about how you need to maximize your protein, but what is protein doing in the body and where did that idea come from? And so, we were trying to really pair back. And I think this is where Kevin's physics training was so wonderful. We were trying to look at like what are these fundamental laws and truths. Things that we know about food and nutrition and how it works in us, and what can we tell people about them. And as we kind of went through that journey it very quickly ended up in an argument about the food environment, which I know we're going to get to. We will. It's really interesting. This idea of how do we know what we know is really fascinating because when you go out there, people kind of tell us what we know. Or at least what they think what we know. But very few people go through that journey of how did we get there. And so people can decide on their own is this a credible form of knowledge that I'm being told to pursue. So Kevin, what do you mean by food intelligence? Coming from a completely different background in physics where even as we learn about the fundamental laws of physics, it's always in this historical context about how we know what we know and what were the kind of key experiments along the way. And even with that sort of background, I had almost no idea about what happened to food once we ate it inside our bodies. I only got into this field by a happenstance series of events, which is probably too long to talk about this podcast. But to get people to have an appreciation from the basic science about what is going on inside our bodies when we eat. What is food made out of? As best as we can understand at this current time, how does our body deal with. Our food and with that sort of basic knowledge about how we know what we know. How to not be fooled by these various sound bites that we'll hear from social media influencers telling you that...

E283: Taylor Hanson's Food On The Move

9/24/2025
Interview Summary You know I really like the innovative nature of Food On The Move, and I'm eager for you to tell us more about what it involves. But before we do that, how does a young, highly successful musician turn to battling food insecurity? What led you to create Food On The Move? It took me years to say I even created it. I didn't even use the term founder because I really had this sense of partnership that was a part of how it came to be. But I did found or 'start' Food On The Move because I have just a deep sense of gratitude in my life experience and also maybe a calling? I call it the tap on the shoulder that said there's more for you to do. There's more for me to do. And I didn't really know what that meant. I wanted to invest in Oklahoma and where we're from because as a musician, first you travel, you leave, you go out, you connect with people all over the world. But there's something about building and doing well for your community from the town you're from. And I was inspired by a former US ambassador. A man named Edward Perkins, who was an incredible representative of our country. He worked in some of the most difficult parts of the world representing the US and working with other nations. And his story struck me so deeply because he found ways to partner and transform communities as an ambassador. And I got to know him after his time as an ambassador because he was teaching as a professor at OU (Oklahoma University), in Oklahoma. And I asked him, I said - I want to honor your life. I want to learn from you. If I was to begin to really impact my community, Oklahoma where I'm from and maybe beyond, where would you begin? And he said, I would start with food. That's so interesting. You know, your concept of partnership is so interesting. I'd like to dive into that a little bit deeper in a little bit. But first, tell us about your organization and what it does, how it works, what it tries to accomplish. Yes. So, inspired by Ambassador Perkins' example, we set out to ask the right questions more than have the answers. And in 2014, I just basically cold called everyone in the community that worked in food - from the food bank to the food pantries and said ‘help me understand the gaps.’ Help me understand where it's hard to accomplish change. And the term food desert began coming up more and more. And food deserts are communities without grocery stores. So, think of it as the canary in the mine. Sort of when a grocery store goes, the neighborhood is declining. Because they're small margin organizations they have a hard time staying afloat and when they go it's hard to bring them back because you need either a company like a big chain or a small business that doesn't have a lot of resources. And oftentimes that decline continues, and it impacts the community. So, with Food On The Move I basically brought together partners to create an access point in food deserts where it's was all in kind. From food trucks that could bring great, tasty food and give people dignity and excitement and energy, to partners that are doing food safety training and teaching people to cook. And places like Oklahoma State University extension where they train people about how to prepare food because they may not know. And so, all these partners came together, and we basically spent five years just learning and serving people in those communities. And focusing on an environment that was not about raising a bunch of money; it was really about who is already in this space that we can garner relationships with and get to know the communities. And now those events continue to be flagships. We call them food and resource festivals. They are a pay-as-you-can. You show up, you get access to fresh produce, you have food trucks, you have wraparound services. You have people that are in the community, in different nonprofits, for-profits, and government organizations that we all collaborate with. And we reach people where they are while serving...

E282: Are healthy, environmentally sustainable diets economically achievable for everyone?

9/19/2025
In today's episode, we're discussing the complex and urgent topic of global food demand. The United Nations Sustainable Development Goals, or SDGs, ask countries to make measurable progress in reducing poverty, achieving zero hunger, and supporting every individual in realizing good health. While also mitigating climate change, sustaining the environment and responsible consumption and production habits. Researchers have recommended sustainable diets - planetary health diets. For example, the Eat Lancet Planetary Health Diet. However, others have criticized some of these diets for not addressing the economic and social impacts of transitioning to such diets. Is it possible to balance changing diets, rising incomes, and economic growth with economic feasibility, environmental impact, and long-term sustainability? Well, that's what our goals are today. Our guests today are Andrew Muhammad of the University of Tennessee Institute of Agriculture, and Emiliano Lopez Barrera from Texas A&M. They are my co-authors on a new paper in the Annual Review of Resource Economics entitled Global Food Demand: overcoming Challenges to Healthy and Sustainable Diets. Interview Summary Andrew let's begin with you. Why is it important to study the economics of dietary habits and food choices in a global context? Well, it's important for several reasons, right? When we think both about food security as well as environmental outcomes and maintaining biodiversity, in keeping both human beings and the planet healthy, we really do need to think about this in a global context. One could see agriculture as a global ecosystem where decisions in one country clearly have impacts on outcomes in others. While at the same time, we need to see food as a means by which we satisfy the demands of a global community. Whether it be through our own domestic production or international trade. And then the last thing I'll say, which is really most important are all the actual things we want to tackle and mitigate and correct, fix or improve. Whether it be the environmental issues, global food security outcomes, individual diets, mitigating obesity issues globally, right? It's pretty clear that most of the things affecting human beings in the environment as it relates to agriculture are global in nature, and there's an economic component that we need to consider when addressing these issues in a global context. Thank you for sharing that. And I am interested to understand what the role of economics in dietary habits is as we explored it in this review paper. In economics, this is a pretty long history, one could say going back centuries, right? This idea of how income growth impacts food spending on a household or individuals, as well as what economic affluence in development does to sort of how diets transition. And so, for example, it's been long established, right, as individuals get richer, a smaller and smaller share of their income is spent on food. So therefore, food dynamics become less important in [a developed, rich country versus a developing country where a large percentage of income is still spent on food. And what does that mean? That means that while I may find price shocks annoying, and while I may find higher grocery prices annoying, in a developing world that clearly has some implications on the nutritional needs and food decisions far more than it would have on me, for example. But the other thing which is something that has been highlighted for quite some time, and that is this transition from basic staples - from rice, grain, corn, cassava, potatoes, etc. - to more complex food products like high protein dense meat products, fish, milk, dairy, and even highly processed products that are deemed unhealthy. But the point is, as we look at the full spectrum of countries from least developed to most developed, you see this transition from basic staples to these protein dense products as well as complex processed products. This is a really important...

E281: Is ultra-processed food still food?

8/28/2025
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...

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

8/25/2025
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...

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

7/31/2025
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...

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

7/15/2025
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...

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

6/27/2025
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...

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

6/20/2025
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...

E275: Against the Grain - A Plea for Regenerative Ag

6/16/2025
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...

E274: Sweet and Deadly - Coca-Cola in the spotlight

6/5/2025
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...

E273: Feeding innovation by taste testing alternative proteins

5/29/2025
As someone who's been mostly vegetarian for a number of years, I have tried a lot of plant-based foods and there's a variety of them. And so how do they really taste, not just from my perspective? Well, it's really important to do really careful analysis, and this is going to be the subject of our conversation today. Plant-based foods are becoming increasingly healthier and cheaper. But one large question really remains for consumers. How do they taste. NECTAR, a nonprofit initiative on a mission to accelerate the alternative protein transition sets out to answer this question. Through large scale blind taste tests with thousands of consumers. NECTAR is amassing the largest publicly available sensory database on alternative protein products. In its latest report, Taste of the Industry 2025, NECTAR conducted blind sensory panels of 122 products across 14 categories and uncovered which products have achieved the taste that's on par with their animal-based counterparts. Today we talk with NECTAR's Director, Caroline Cotto, about which products are meeting and exceeding consumer taste expectations and what the alternative protein industry needs to do to get more products to this level. And how NECTAR's novel dataset can be used to get there faster. Interview Summary I understand you've conducted the world's largest clinical sensory test for plant-based and alternative meats compared to real animal meat. Tell me about how you conducted this study and why NECTAR is focused on this research. Absolutely. So, for us, we're really focused on this research because we know that taste is a major purchase driver for consumers and it's often the key reason people cite for not repurchasing plant-based meats once they've purchased them. We really want people to come back to the category and so in order for that to happen, we need taste to be where consumers expect it to be. As you mentioned, we set out to conduct a large study and sort of understand where the products on the market taste today. So, we tested 122 products across 14 categories. And we chose those categories by looking at the highest volume selling categories of animal meat, and then mapping the plant-based products to those categories. And then 43 of those products were from Europe as well. So, we were trying to get a real landscape analysis. Different than traditional sensory testing, we conducted all of our studies in restaurant settings to give a more natural experience for the participants. And all of our testing is done with omnivore consumers. So, we love vegans and vegetarians, but we're really trying to go after that hardcore meat eater and see if we can get them to switch because they love the taste of these products. And then the other difference is that we serve everything in what we call a full build. We serve burger patties and buns, hot dogs and buns. We really allow consumers to apply condiments as long as they do it equally across all of the products that they're testing, um, to give that authentic experience as they would experience the product in their own kitchen. And we ended up having 2,684 participants in this city. Each product was tried by a minimum of 100 consumers. Wow, that's pretty extensive. What were some of the surprising results of this? Yeah, I think we found that the average plant-based product was not quite ready for mainstream adoption. The average plant-based product was generally disliked more frequently than the animal product was, with 35% of tasters rating the product. Some form of dislike. And only 9% of tasters rating animal products as some form of dislike. That said, we did find 20 products out of the 122 that were worth celebrating. We created the Tasty Awards based on this data. And we set a threshold for top performance. And that threshold was that of the people that tried the product, if at least 50% of them said that it, that plant-based meat was the same or better than the animal meat that it was considered a winner...

E272: Why getting food date labeling right is so darn tough

5/22/2025
Do you pay attention to information printed on food labels? From eye-catching designs companies use to entice you to buy a product to nutrition facts panels to the tiny dates printed on packages. There's a lot going on to be sure. For policymakers, they hope that refining date labels on food packaging will help reduce the amount of uneaten food ending up in landfills. Food Waste is a major contributor to greenhouse gas emissions. The Food and Drug Administration and the Food Safety and Inspection Service recently asked for public input on food date labels. So, we decided to gather some experts together to talk about this important policy tool. Roni Neff is a professor in the Johns Hopkins Bloomberg School of Public Health and Senior Advisor at the School's Center for a Livable Future. Her research looks at the intersection of food waste policy, climate change, and food system resilience. Brian Roe is a professor at the Ohio State University Department of Agricultural, Environmental and Developmental Economics. His work focuses on issues including agricultural marketing, information policy, behavioral economics, and product quality. Ruiqing Miao is an associate professor of agricultural economics and rural sociology at Auburn University's College of Agriculture. His research emphasizes sustainability, innovation, and decision making. Interview Summary Brian, let's begin with you and let's make sure everyone's on the same page. Can you talk to us a little bit about what date labels are and where they are on packaging. And what is industry required to include in terms of these date labels? Yes, so date labels, we see them anytime we pick up a food package. Most packages are going to have some type of date label on them. Oddly, federal law doesn't regulate these or really require these other than the exception of infant formula, which is the only federal requirement domain out there. But in the absence of federal regulation, states have kind of done their own thing. About 40 different states require date labels on at least some food products. And about 20 states prohibit or restrict the sale or donation of food past the label date. And even though states that require date labels, manufacturers can still choose the dates. There are no real regulations on them. So, recognizing that confusion over date labels can lead to unnecessary food waste, Government and industry actors have made, you know, some efforts to try to standardize date labeling language. But nothing terribly authoritative. Now, some states have introduced bills that seek to standardize date labels, with the motivation to try to get rid of and reduce food waste. California being perhaps the most recent of these. In 2024, they passed a bill that prohibits the use of any date label other than 'Best if Used By,' the phrase that goes along with foods where the date represents kind of a quality indicator. And then the phrase 'Use By,", if that date has some implications for product safety. The bill doesn't go into effect until July of '26, so we're going to see if this is going to create a domino effect across other states, across the food manufacturing center or even bubble up and be dealt with at the federal legislation level. Now, industries tried to do things before. Back in 2017, the Food Marketing Institute and the Grocers Manufacturers Association had a standardized date labeling suggestion that some firms bought into. FDA has given out some guidance about preferring 'Best if Used By' on certain food products to indicate quality. But again, we're all kind of waiting to see if there might be a federal legislation that kind of brings these state labels into check. Thanks, Brian. And it's really important to know about the policy landscape and the fact that there hasn't been a federal policy across all foods. And it's interesting to see the efforts of, say, in California. I think this begs the question; how do consumers actually process the information of date...

E271: Grappling with digital food and beverage marketing to youth

5/13/2025
So even the people that follow the topic closely are stunned by the digital landscape that engulfs our children, how quickly it evolves, and the potential social cost. Two people in a unique position to explain all this are our guest today, Jeffrey Chester and Kathryn Montgomery, both from the Center for Digital Democracy. Jeff is executive director of the Center, and Kathryn is its research director and senior strategist, as well as professor emerita of communication at American University. Jeff and Kathryn have been pioneers in this work and have been uniquely strong voices for protecting children. Interview Summary Let me congratulate the two of you for being way ahead of your time. I mean the two of you through your research and your advocacy and your organizational work, you were onto these things way before most people were. I'm really happy that you're joining us today, and welcome to our podcast. Kathryn, let me begin with you. So why be concerned about this digital landscape? Kathryn - Well, certainly if we're talking about children and youth, we have to pay attention to the world they live in. And it's a digital world as I think any parent knows, and everybody knows. In fact, for all of us, we're living in a digital world. So young people are living their lives online. They're using mobile phones and mobile devices all the time. They're doing online video streaming. They form their communications with their peers online. Their entire lives are completely integrated into this digital media landscape, and we must understand it. Certainly, the food and beverage industry understand it very well. And they have figured out enormously powerful ways to reach and engage young people through these digital media. You know, the extent of the kids' connection to this is really remarkable. I just finished a few minutes ago recording a podcast with two people involved with the Children and Screens organization. And, Chris Perry, who's the executive director of that organization and Dmitri Christakis who was with us as well, were saying that kids sometimes check their digital media 300 times a day. I mean, just unbelievable how much of this there is. There's a lot of reasons to be concerned. Let's turn our attention to how bad it is, what companies are doing, and what might be done about it. So, Jeff, tell us if you would, about the work of the Center for Digital Democracy. Jeff - Well, for more than a quarter of a century, we have tracked the digital marketplace. As you said at the top, we understood in the early 1990s that the internet, broadband what's become today's digital environment, was going to be the dominant communications system. And it required public interest rules and policies and safeguards. So as a result, one of the things that our Center does is we look at the entire digital landscape as best as we can, especially what the ultra-processed food companies are doing, but including Google and Meta and Amazon and GenAI companies. We are tracking what they're doing, how they're creating the advertising, what their data strategies are, what their political activities are in the United States and in many other places in the world. Because the only way we're going to hold them accountable is if we know what they're doing and what they intend to do. And just to quickly follow up, Kelly, the marketers call today's global generation of young people Generation Alpha. Meaning that they are the first generation to be born into this complete digital landscape environment that we have created. And they have developed a host of strategies to target children at the earliest ages to take advantage of the fact that they're growing up digitally. Boy, pretty amazing - Generation Alpha. Kathryn, I have kind of a niche question I'd like to ask you because it pertains to my own career as well. So, you spent many years as an academic studying and writing about these issues, but also you were a strong advocacy voice. How did you go...

E267: Do food labels influence kids' snack shopping choices?

4/16/2025
As any parent knows, it is really important to help our children to make healthy food choices. I know as a father who cooks for my child, it is really critical that I introduce her to fruits and vegetables and encourage whole grains and try to manage the amount of additional sugars, but it's hard. We do this with the goal of trying to make sure that our child is able to eat healthy once she leaves the home. That she's able to make healthy choices there. But it's not just about the future. My child is making choices even today at school and outside of school, and the question is, can we help her make those choices that are going to lead to healthy food outcomes? Do food labels on products encourage children to make healthy food choices if it indicates good ingredients? Or would labels that warn against nutrients of concern actually discourage kids from using those or consuming those products? Today we're going to actually explore those questions in a particular context- in Chile. In 2016, the Chilean government implemented a comprehensive set of obesity prevention policies aimed at improving the food environment for children. Last year on this podcast, we actually explored how the Chilean food laws affected school food purchases. But now today, we're going to explore how food labels are influencing youth outside of school. It is my pleasure to welcome back my colleagues, Gabriela Fretes, who is an associate research fellow at the International Food Policy Research Institute, or IFPRI; and Sean Cash, who is an economist and chair of the Division of Agriculture, food and Environment at Tufts University at the Friedman School of Nutrition, Science and Policy. Interview Summary Gabi and Sean, I'm excited to discuss our new paper, Front of Pack Labels and Young Consumers an Experimental Investigation of Nutrition and Sustainability Claims in Chile that was recently published in a Journal of Food Quality and Preference. Gabi, let's begin with you. So why look at Chile? Can you explain the focus of the Chilean labeling and food environment policies there? So, the setting of our study, as in the previous study, was Chile because recently the country implemented the law of food labeling and advertising, which includes three main components. The first one being mandatory front of package warning labels on packaged goods and beverages. The second one being restrictions on all forms of food marketing directed to children younger than 14 years. So, including printed media, broadcast, and also all digital media. And the third component being at school regulations at different levels including preschool, elementary, and high school levels. Briefly, food manufacturers in Chile must place front of package labels on packaged foods or beverages that are high in specific nutrients of concern, including added sugars, saturated fats, sodium, and or energy. This law was implemented in three stages, starting in June 2016. The last stage was implemented in June 2019. So, it has been already six or seven years since the full implementation of the regulation. Specifically talking about the school component because this, yeah, it relates to children and adolescents. The law mandates that foods and beverages with at least one front of pack warning label cannot be sold, promoted, or marketed inside schools. And this includes the cafeteria, the school kiosks, and even events that are happening inside the schools. And additionally, food and beverages that have at least one front pack warning label cannot be offered as part of school meal programs. In addition to this front of pack warning label regulation, Chile also implemented voluntary eco labels starting in 2022 that provide information about the recyclability of food packages specifically. There is a certification process behind this labeling regulation and the eco label can be displayed if the food or beverage package is at least 80% recyclable. Wow. This is a really comprehensive set of policies...

E269: Children, screen time and wellbeing - many reasons for concern

4/9/2025
The amount of time children and adolescents spend with a screen is absolutely stunning. Lots of people, including parents, health leaders, educators, elected leaders from both parties I might mention, and even children themselves, are highly concerned and are discussing what might be done about all this. I'm delighted to begin this series of podcasts on children and screen time. Today we're welcoming two very special guests who can talk about this topic in general, and especially about what's being done to protect children and adolescents. Several podcasts will follow this one that deal with food and nutrition in particular. Our first guest, Kris Perry, is Executive Director of Children and Screens, an organization devoted to protecting children. In the digital world by addressing media's impact on child development, communicating state-of-the-art information, and working with policymakers. Prior to joining children in Screens, Kris was senior advisor of the Governor of California and Deputy Secretary of the California Health and Human Services Agency. Our other guest, Dr. Dimitri Christakis is a professor of pediatrics at the University of Washington School of Medicine, and director of the Center for Child Health Behavior and Development at Seattle Children's. He's also editor-in-chief of JAMA Pediatrics and both Chief Scientific Officer and Chair of the Scientific Advisory Board of Children and Screens. He's also the co-editor of a new book that I'm very excited to discuss. Interview Summary Download The Handbook of Children and Screens: https://link.springer.com/book/10.1007/978-3-031-69362-5 Kris, let's start with you. Could you set the stage and give us some sense of how much time children spend in front of screens, children and adolescents, and what devices are being used and what kind of trends are you seeing? Yes, I'd be happy to. I had better news for your listeners, but as you might imagine, since the advent of the smartphone and social media, the youth digital media use has been increasing each year. Especially as children get older and have increasing demands on their time to use screens. But let's just start at the beginning of the lifespan and talk about kids under the age of two who shockingly are spending as much as two hours a day on screens. Most spend about 50 minutes, but there's a significant chunk spending up to two hours. And that rises to three or three to five hours in childhood. And eventually in adolescence, approximately eight and a half hours a day our adolescents are spending online. Also wanted to talk a little bit about middle childhood children, six to 12 years of age. 70% of them already have a social media account, and we all know social media wasn't designed for children. And there are restrictions on children under 13 using them, and yet children six to 12 most have an account already. Over half of four-year-olds have a tablet and two thirds of children have their own device by the age of eight; and 90% of teens. This probably won't be surprising, and yet we should really think about what this means; that 90% of teens are using YouTube, 60% are on TikTok and Instagram, and 55% use Snapchat. I'll stop by ending on a really alarming statistic. Oh my, there's more? There's more. I know it! I told you. I'll be the bearer of bad news so that we can talk about solutions later. But, children are checking their devices as often as 300 times per day. 300 times. 300 times per day, and we're talking about screen time right now. And we know that when you're using time to be on screens, you are not doing something else. And we know that childhood is full of challenges and skill building and mastery that requires repetition and tenacity and grit and effort. And the more children are on their screens, whether it's social media or other entertainment, they're not doing one of these other critical child development tasks. That's pretty amazing. And the fact that the older kids are spending more...

E268: Why Corporate Control of Agriculture is Cause for Concern

3/26/2025
How big is too big? When it comes to corporate concentration many observers raise concerns about the tech industry. However, in the new book, Titans of Industrial Agriculture: how a few giant corporations came to dominate the farm sector and why it matters, political economist Jennifer Clapp draws attention to the overwhelming shadow a small handful of transnational corporations cast over the global agricultural sector. Professor Clapp argues that these corporations hold concentrated power over the agricultural sector that keep industrial agricultural practices entrenched in patterns of production, despite the concerns of the social, ecological and health impacts to society. She explains how we got to this point and what it might take to make changes. Jennifer's work at the intersection of the global economy, food security, and food systems, and the natural environment, looks specifically at issues of global governance. She is currently a member of the International Panel of Experts on Sustainable Food Systems, and a member of the Scientific Advisory Committee of the UN Food Systems Coordination Hub. Interview Summary Norbert - Jennifer, let's just jump right in and I'd love for you to help our listeners understand a little bit more about your book. You write about corporate concentration in the agricultural input sector. Can you explain what this involves and what products are we really talking about? Yes. The book is about what we call the agricultural inputs industry. And that's really four different product types typically, and maybe a fifth that we can talk about. So, one of them is farm machinery, and that's really referring to things like plows and tractors, harvesters, etc. That kind of machinery on the farm. The second industry is the fertilizer industry, which is all about, you know, the nutrients that we bring to the soil through fertilizer products like nitrogen, phosphorus, and potash. And the seed industry. That's another industry that is a key input for farmers. And then also pesticides. And when we talk about pesticides, we're referring to things like insecticides, chemicals that kill insects, but also chemicals that kill weeds and fungus. And so those are the four sort of big inputs that I talk about in the book. But also, the book covers a fifth input, an emerging input, which is data. And this is, especially as we're seeing the datafication and digitalization of farming. Increasingly data has now become a commodity that is bought and sold as an input into farming. Norbert - Great. I have to ask, what drew you to the input industry? I mean, let's be honest, that's not the thing that most people get excited about. Why should we be concerned? Yeah, that's a great question. I've actually had a very long interest in the seed in chemical industry. That goes way back to the start of my career because I did studies in agriculture for my PhD dissertation. But then I got quite interested in toxic waste and then that sort of drew me to this question of the global pesticide trade. And when I learned that, you know, oftentimes, like in the US there might be a banning of a pesticide that's no longer in use. But it was still being traded globally. And this, I found this very fascinating and how that industry worked. And that kind of drew me into understanding the connections between seeds and chemicals. And then when the digitalization of farming came along and in recent decades it became really clear that it wasn't just chemical and seed industry involved in that digitalization. It was also the fertilizer and the farm machinery sector. It made me want to understand the interconnections between these industries. I know it's like, maybe a bit specific, but they have huge consequences in terms of the way our food systems look like. And so that really drew me to understand where did these inputs come from? And why are they controlled by just a few large companies? Erika - Jennifer, I want to ask you a question about...
