The Science That Feeds Us

In this episode, Katie and Bhavisha take a step away from the data and into the harder, often unspoken questions that shape science communication in practice. We reflect on what it means to do this work in spaces where expertise, public values, and lived experience do not always align, and where simply presenting the facts falls short. Drawing on our own experiences, we talk through moments where advocating for evidence can feel at...

In this episode, Dr. Melinda Knuth joins us to unpack the science and social dynamics behind glyphosate, one of the most widely used and debated weed control products. Dr. Knuth explains what glyphosate is, how it works, and how recent lawsuits, questions about scientific transparency, and differing global health conclusions have contributed to public uncertainty. From a consumer behavior perspective, we explore how trust, social m...

In this episode, we sit down with Dr. Ellen Shumaker to explore the science behind food safety and the systems that protect our food from farm to fork. Dr. Shumaker breaks down what food safety really means from a scientific perspective, how research informs cooking temperatures and storage guidelines, and why simple tools like food thermometers and refrigerator thermometers matter more than we think. We dive into common consumer r...

In part three of our land-grant series, we turn to the final pillar of the land-grant mission: Extension. We’re joined by Dr. Annie Hardison-Moody and Dr. Misty Blue-Terry to explore how Extension connects research and teaching directly to communities across North Carolina. Together, they explain what Cooperative Extension is, why it was created, and how it continues to serve as the outreach arm of land-grant universities. We also ...

In part two of our land-grant series, Dr. Joseph Donaldson joins us to explore what makes land-grant teaching distinct from other higher education models. From the federal mandate that defines land-grant institutions to the balance of theory and hands-on learning reflected in mottos like “Think and Do,” Dr. Donaldson explains how land-grant programs intentionally prepare students for real-world careers. We discuss how land-grant te...

In this episode, we kick off a three-part series exploring the land-grant university system by focusing on the first pillar of its mission: research. We sit down with Dr. Ben Chapman to discuss how research within the land-grant system developed historically and why it plays such an important role in supporting agriculture, food systems, and communities. Dr. Chapman explains what makes land-grant research unique, particularly its s...

In this episode, Dr. Jonathan Allen joins us to unpack the science behind some of today’s most popular dietary supplements and the claims that surround them. From protein powders and creatine and their role in muscle development and brain energy, to collagen supplements marketed for beauty and health, and even the rise of greens powders as a convenient nutrition option, Dr. Allen explains what the evidence actually shows and where ...

In this episode, we sit down with Dr. Manuel Kleiner to explore all things gut health. Dr. Kleiner breaks down how trillions of bacteria work together to help us digest food, protect our health, and shape the way our bodies function. We dive into his research on how different protein sources, like eggs, red meat, and plant proteins, can alter the microbiome and impact long-term health. He also shares science-backed advice for suppo...

In this episode, we sit down with Dr. Carrie Pickworth to break down one of the most talked-about and often misunderstood topics in food and agriculture: beef production. From grass-fed to grain-fed systems, Dr. Pickworth explains what these production terms actually mean and how beef cattle are raised across different stages of their lives. We explore how cattle diets influence growth, efficiency, and meat quality, what science sa...

In this episode, Dr. Chris Taylor joins us to unpack the growing conversation around processed and ultra-processed foods, and why these labels often oversimplify a much more complex food system. From common claims about additives, preservatives, and metabolic health, Dr. Taylor explains what food processing really means and where the evidence still falls short. We explore how nutrient density, fiber, energy density, and substitutio...

In this episode, Dr. Dara Bloom and Dr. Allison Pullin joined us to unpack what food labels and animal certifications really mean and why they can be so confusing for consumers. From third-party verification and auditing standards to recordkeeping on farms, our guests explain how these programs are designed, how they are implemented across different farming systems, and where flexibility exists to balance animal health with practic...

In this episode, we sit down with Dr. Eric Trexler to unpack why protein has exploded from a niche fitness topic into a full-blown wellness trend, and what the science actually says behind the hype. From the rise of resistance training to misconceptions about protein needs, Dr. Trexler explains how protein works in the body, why lifters need it differently than sedentary consumers, and how muscle growth really happens. We explore p...

In this episode, Dr. Lynette Johnston joins us to explore the science, use, and safety of one of the most common artificial food colors: red dye #40. Dr. Johnston explains where this dye shows up in our everyday lives, and why it is used so extensively in our food system. We discuss how the FDA regulates artificial dyes, what current research says about potential health effects, and how dose, context, and individual sensitivities p...

In this episode, we sat down with Dr. Basheerah Enahora to unpack the science and controversy behind two of the most debated sweeteners in our food system: high fructose corn syrup and cane sugar. From their nearly identical chemical structures to how our bodies metabolize them, Dr. Enahora explains why the real concern lies not in the source of sugar but in how much of it we consume. She also explores how cost, processing, and con...

In this episode, Dr. Khara Grieger and Dr. Katy May join us to explore the growing concern around PFAS, often called “forever chemicals,” and their connection to our food and water systems. From cookware and cosmetics to contaminated rivers in North Carolina, they unpack how PFAS make their way into our bodies and the risks they pose for human health, farmers, and local communities. We discuss what the science does and doesn’t yet ...

In this episode, Dr. Carolyn Bird joins us to unpack the role of SNAP outreach in connecting families to vital food resources. She explains how the More In My Basket program works to reduce barriers, simplify applications, and raise awareness of benefits many people don’t realize SNAP offers. We explore the challenges of keeping benefits aligned with rising food costs, innovations that could streamline enrollment, and the importanc...

In this episode, Tammy Brunelle and Kim Eshleman join us to unpack the Supplemental Nutrition Assistance Program’s education arm, SNAP-Ed, and its role in promoting healthier communities. We explore how SNAP-Ed goes beyond food assistance to support nutrition education, policy, systems, and environmental changes that make healthy choices more accessible. They share powerful stories from their work, highlighting how small shifts can...

In this episode, Dr. Sarah Bowen and Dr. Annie Hardison-Moody join us to explore the Supplemental Nutrition Assistance Program (SNAP), and the stories, science, and policies behind it. We talk about who uses SNAP, what it actually provides, and how it became one of the most effective tools for fighting food insecurity in the U.S. We also unpack common myths and look at new policy proposals that could reshape how the program works. ...

In this episode, we turn the mic on ourselves to share the story behind The Science That Feeds Us. We talk about how our own paths led us into science and communication, and why this podcast exists in the first place. At the core is our belief that storytelling makes science more human, more relatable, and ultimately more impactful. We explore what makes food systems communication different from agricultural communication, and why ...
