  • Pathway to Market is Complicated for Cell-Cultivated Protein

    Pathway to Market is Complicated for Cell-Cultivated Protein
    Feb 24 2026
    As global demand for meat grows, this episode of Duke University's Leading Voices in Food podcast examines cell-cultivated protein—real meat grown from animal cells—and the evolving U.S. policy landscape shaping its future. Host Norbert Wilson (Duke World Food Policy Center) speaks with postdoctoral researchers Kate Consavage Stanley (Duke/Bezos Center for Sustainable Proteins) and Katariina Koivusaari (NC State/Bezos Center) about their article in Trends in Food Science and Technology on U.S. regulatory and legislative activity. The conversation explains the joint FDA–USDA regulatory approach for cell-cultivated meat (FDA oversight through cell cultivation; USDA oversight from harvest through processing, packaging, and labeling) and FDA oversight for cell-cultivated seafood (except catfish). They discuss timelines companies report for approval (often two to three years), the lack of federal public guidance on naming and labeling so far, and how USDA label approvals are currently handled case by case (e.g., "cell-cultivated chicken" and "cell-cultivated pork"). The episode also covers state-level labeling laws and the likelihood of federal preemption if state requirements conflict with federal statutes, as well as a growing wave of state restrictions and bans—Florida and Alabama in 2024, followed by Indiana, Mississippi, Montana, Nebraska, and Texas in 2025—plus funding restrictions in South Dakota and Iowa. The guests explore implications for consumers, interstate commerce, innovation, investment, and U.S. leadership, noting ongoing lawsuits in Florida and Texas and continued legislative activity such as a proposed ban in Georgia. Interview Transcript Kate, let's begin with you. In the paper, you write about the regulatory frameworks that have been developed for cell-cultivated meat and seafood products in the US. To start, let's talk about what's unique about cell-cultivated products from a regulatory standpoint and how the US Department of Agriculture and US Food and Drug Administration have decided to handle cell-cultivated protein products. Kate - Yes, so as you mentioned in the introduction, Norbert, cell-cultivation is a new technology for use of the food supply. So, the US government had to adapt its existing legal frameworks for food safety regulation. As your listeners may already know seafood is regulated by the FDA, so it was within their scope to also regulate cell-cultivated seafood. The FDA therefore regulates all cell-cultivated seafood products with the exception of catfish. When it came to determining the regulatory approach for cell-cultivated products from livestock, poultry, and catfish, it was a bit more nuanced as the processes and components evolved fell under both USDA and FDA purview. In 2019, the FDA and USDA therefore agreed on a joint regulatory approach where the FDA regulates the early stages of the cell cultivation process, including when those cells are taken from the animal, grown in the bioreactor, and matured into specific cell types such as muscle or fat cells. At the point where those cells are ready to be harvested from the bioreactor to use in a food product, oversight transfers to USDA who oversees that harvesting process as well as food processing, packaging, and labeling. I know this joint regulatory approach may sound complicated, but it's important to note that USDA and FDA already coordinate oversight over other foods in the food supply. I'll give you an example that we all love pizza. A frozen cheese pizza is regulated by the FDA, whereas a frozen pizza with meat toppings like pepperoni is regulated by the USDA. It is therefore not unprecedented that FDA and USDA would agree to jointly regulate cell-cultivated products. And while the process is new, the products go through the same safety checks as other foods in the food supply. In the past few years, we've seen four cell-cultivated meat products go through the joint USDA-FDA regulatory process, meaning they can be sold in the US food supply. And one cell-cultivated seafood product has gone through the FDA regulatory process. Kate, thank you for sharing this. And I've used a pizza example in my class, and it is super complex this regulatory maze that we're talking about. It seems like there has been a lot of collaboration between these two agencies, and so that's important to hear. But it is also the case that it seems challenging for cell-cultivated protein companies to get through this process. Is this a fair assessment and would you elaborate? Kate - Yes, absolutely. We've heard from cell-cultivated companies that it can take two to three years to get through this process. And there certainly is a lot of back and forth between the companies and FDA and USDA. Great, thank you. Katariina, now let's turn to you. How do these regulations extend to labeling and what do we know about the federal government's approach to labeling the sale of cultivated products thus far? Katariina – So, ...

  • E290: Grading the Biggest US Grocery Stores on Healthy Offerings

    E290: Grading the Biggest US Grocery Stores on Healthy Offerings
    Jan 15 2026
    Do you ever wonder whether your grocery store cares about whether you have a healthy diet? Every time we shop or read advertisement flyers, food retailers influence our diets through product offerings, pricings, promotions, and of course store design. Think of the candy at the checkout counters. When I walk into my Costco, over on the right there's this wall of all these things they would like me to buy and I'm sure it's all done very intentionally. And so, if we're so influenced by these things, is it in our interest? Today we're going to discuss a report card of sorts for food retailers and the big ones - Walmart, Kroger, Ahold Delhaize USA, which is a very large holding company that has a variety of supermarket chains. And this is all about an index produced by the Access to Nutrition Initiative (ATNi), a global foundation challenging the food industry investors and policy makers to shape a healthier food system. The US Retail Assessment 2025 Report evaluates how these three businesses influence your access to nutritious and affordable foods through their policies, commitments, and actual performance. The Access to Nutrition Initiatives' director of Policy and Communications, Katherine Pittore is here with us to discuss the report's findings. We'll also speak with Eva Greenthal, who oversees the Center for Science in the Public Interest's Federal Food Labeling work. Interview Transcript Access ATNi's 2025 Assessment Report for the US and other countries here: Retail https://accesstonutrition.org/index/retail-assessment-2025/ Let's start with an introduction to your organizations. This will help ground our listeners in the work that you've done, some of which we've spoken about on our podcast. Kat, let's begin with you and the Access to Nutrition Initiative. Can you tell us a bit about the organization and what work it does? Kat Pittore - Thank you. So, the Access to Nutrition Initiative is a global foundation actively challenging the food industry, investors, and policymakers to shape healthier food systems. We try to collect data and then use it to rank companies. For the most part, we've done companies, the largest food and beverage companies, think about PepsiCo, Coca-Cola, and looking are they committed to proving the healthiness of their product portfolios. Do the companies themselves have policies? For example, maternity leave. And these are the policies that are relevant for their entire workforce. So, from people working in their factories all the way up through their corporate areas. And looking at the largest companies, can these companies increase access to healthier, more nutritious foods. One of the critical questions that we get asked, and I think Kelly, you've had some really interesting guests also talking about can corporations actually do something. Are corporations really the problem? At ATNi, we try to take a nuanced stance on this saying that these corporations produce a huge amount of the food we eat, so they can also be part of the solution. Yes, they are currently part of the problem. And we also really believe that we need more policies. And that's what brings us too into contact with organizations such as Eva's, looking at how can we also improve policies to support these companies to produce healthier foods. The thought was coming to my mind as you were speaking, I was involved in one of the initial meetings as the Access to Nutrition Initiative was being planned. And at that point, I and other people involved in this were thinking, how in the world are these people going to pull this off? Because the idea of monitoring these global behemoth companies where in some cases you need information from the companies that may not reflect favorably on their practices. And not to mention that, but constructing these indices and things like that required a great deal of thought. That initial skepticism about whether this could be done gave way, at least in me, to this admiration for what's been accomplished. So boy, hats off to you and your colleagues for what you've been able to do. And it'll be fun to dive in a little bit deeper as we go further into this podcast. Eva, tell us about your work at CSPI, Center for Science in the Public Interest. Well known organization around the world, especially here in the US and I've long admired its work as well. Tell us about what you're up to. Eva Greenthal - Thank you so much, Kelly, and again, thank you for having me here on the pod. CSPI is a US nonprofit that advocates for evidence-based and community informed policies on nutrition, food safety and health. And we're well known for holding government agencies and corporations to account and empowering consumers with independent, unbiased information to live healthier lives. And our core strategies to achieve this mission include, of course, advocacy where we do things like legislative and regulatory lobbying, litigation and corporate accountability initiatives. We also do policy and ...

  • Posting calorie counts on menus should be just one strategy of many

    Posting calorie counts on menus should be just one strategy of many
    Dec 16 2025
    In this episode of the Leading Voices in Food podcast, Norbert Wilson of Duke University's Sanford School of Public Policy speaks with researchers Jean Adams from the University of Cambridge and Mike Essman from Duke's World Food Policy Center. They discuss the mandatory calorie labeling policy introduced in England in April 2022 for large food-away-from-home outlets. The conversation covers the study recently published in the British Medical Journal, exploring its results, strengths, limitations, and implications within the broader context of food labeling and public health policies. Key findings include a slight overall reduction in calorie content offered by food outlets, driven by the removal of higher-calorie items rather than reformulation. The discussion also touches on the potential impacts on different consumer groups, the challenges of policy enforcement, and how such policies could be improved to more effectively support public health goals. Interview Summary Now everyone knows eating out is just part of life. For many, it's a place to make connections, can be a guilty pleasure, and sometimes it's just an outright necessity for busy folks. But it is also linked to poor dietary quality, weight gain, and even obesity. For policymakers, the challenge is identifying what policy changes can help improve population health. Jean, let's begin with you. Can you tell our listeners about the UK's menu labeling intervention and what change did you hope to see? Jean - Yes, so this was a policy that was actually a really long time in coming and came in and out of favor with a number of different governments. So maybe over the last 10 years we've had various different suggestions to have voluntary and/or mandatory calorie labeling in the out-of-home sector. Eventually in April, 2022, we did have new mandatory regulations that came into a force that required large businesses just in England - so not across the whole of the UK, just in England - if they sold food and non-alcoholic drinks and they had to display the calories per portion of every item that they were selling. And then have alongside that somewhere on their menu, a statement that said that adults need around 2000 calories per day. The policy applied just to large businesses, and the definition of that was that those businesses have 250 or more employees, but the employees didn't all have to be involved in serving food and drinks. This might apply also to a large hotel chain who just have some bars or something in their hotels. And the food and drinks covered were things that were available for immediate consumption. Not prepackaged. And then there was also this proviso to allow high-end restaurants to be changing their menus regularly. So, it was only for things that were on the menu for at least 30 days. You mentioned that this policy or a menu labeling might have at least two potential modes of impacts. There's first this idea that providing calories or any sort of labeling on food can somehow provide information for consumers to make what we might hope would be better choices. Might help them choose lower calorie options or healthier options. And then the second potential impact is that businesses might also use the information to change what sort of foods they're serving. It might be that they didn't realize how many calories were in the foods and they're suddenly embarrassed about it. Or as soon as their customers realize, they start to put a little bit of pressure on, you know, we want something a little bit lower calorie. So, there's this potential mechanism that operates at the demand side of how consumers might make choices. And another one at the supply side of what might be available to consumers. And we knew from previous evaluations of these sorts of interventions that there was some evidence that both could occur. Generally, it seems to be that findings from other places and countries are maybe null to small. So, we were thinking that maybe we might see something similar in England. Thank you for sharing that background. I do have a question about the length of time it took to get this menu labeling law in place. Before we get into the results, do you have a sense of why did it take so long? Was it industry pushback? Was it just change of governments? Do you have a sense of that? Jean - Yes, so I think it's probably a bit of both. To begin with, it was first proposed as a voluntary measure actually by industry. So, we had this kind of big public-private partnership. What can industry do to support health? And that was one of the things they proposed. And then they didn't really do it very well. So, there was this idea that everybody would do it. And in fact, we found maybe only about 20% of outlets did it. And then definitely we have had government churn in the UK over the last five years or so. So, every new prime minister really came in and wanted to have their own obesity policy threw out the last one started over. And every ...
