Sipping on Evidence

About Sipping on Evidence

Welcome to the podcast Sipping on Evidence, where we invite you to slowly take in the stories of your peers. It is a little bit like the difference between sipping water over time and gulping down a litre. So, grab a glass…In this podcast we are sharing stories about nutrition and dietetics professionals who are leading innovative work on transitions to sustainable dietary patterns in the face of systemic barriers, rapid change and uncertainty. We talk about impact, evidence, and what it takes to lead in this space.

   Introduction

   This podcast shares the outcomes of our research examining the Social Impact Potential (SIP!) of dietitians on healthy and sustainable dietary patterns across several countries. “Sipping on Evidence” invites you to slowly take in the stories from your peers, nutrition and dietetics professionals who are leading innovative work that supports transitions to sustainable dietary patterns in the face of systemic barriers, rapid change and uncertainty. We also move beyond innovation to ask hard questions like: how do we know the actions generate impact? What constitutes impact, or evidence? What other impacts should we be counting? Grab a glass and join us as your colleagues share their ideas! The work was funded by a Social Sciences and Humanities Research Council of Canada (SSHRC) Insight Development Grant and St. Francis Xavier University. We also credit Acadia University and Toronto Metropolitan University for much support along the way.

   Systems thinking as sustainable food systems pedagogy - Part 1

   In this episode, we talk to innovative practitioners who are using systems thinking as a pedagogical tool in nutrition and dietetics education to help students understand the complexity of food, nutrition, health and the broader systems in which these interact. We will also explore their ideas about evidence of impact, specifically regarding how their activities help foster student learning and skill development related to the adoption, or uptake, of healthy dietary patterns that support more sustainable food systems. Key points we will explore include: Using systems thinking as a framework to help students become better problem solvers, to get at the root causes of challenges they will face in their future work. Ideas for experiential ways to put systems thinking into practice so that students develop skills that can be scaled up to the broader community when they enter the workforce. Guests: Part 1: Erin Bergquist is a dietitian and Clinical Professor with Iowa State University’s Food Science and Human Nutrition Department, teaching in the Master of Professional Practice program. Erin was a member of the workgroup that developed the Standards of Professional Performance for Registered Dietitian Nutritionists in Sustainable, Resilient, and Healthy Food and Water Systems, and she also served as a co-lead in developing the dietetic internship concentration in Sustainable, Resilient, and Healthy Food and Water Systems. Her current research and teaching focus is sustainable food systems in the context of dietetics education.  It is fair to say that Erin has been, and continues to be, a solid champion in creating education and training opportunities in sustainable food systems, inspiring and fostering knowledge and skill development among nutrition students. Check out Erin’s recent work: Bergquist, E., and Tagtow, A. (2025). Strategies for Systems Thinking and Sustainable Food Systems Integration in Dietetics Education.

   Systems thinking as sustainable food systems pedagogy - Part 2

   In this episode, we  talk to innovative practitioners who are using systems thinking as a pedagogical tool in nutrition and dietetics education to help students understand the complexity of food, nutrition, health and the broader systems in which these interact. We will also explore their ideas about evidence of impact, specifically regarding how their activities help foster student learning and skill development related to the adoption, or uptake, of healthy dietary patterns that support more sustainable food systems. Key points we will explore include: Using systems thinking as a framework to help students become better problem solvers, to get at the root causes of challenges they will face in their future work. Ideas for experiential ways to put systems thinking into practice so that students develop skills that can be scaled up to the broader community when they enter the workforce. Sandy Murray, is a dietitian and a lecturer in food science and public health nutrition within the University of Tasmania(U-TAS), teaching in the Bachelor of Nutrition Science, a pathway degree to a Masters of Dietetics. With over 35 years of experience across public health and community nutrition, food industry, and higher education, Sandy brings expertise in participatory food governance research. She also serves on the leadership team of Dietitians Australia’s Food and Environment Interest Group. Like our first guest, she has been using a systems approach within her university setting, not only in her teaching but also through campus research projects such as the UTAS Healthy Sustainable and Equitable Food Strategic Plan. Often working “by stealth”, Sandy embeds sustainable food systems into her teaching and practice, finding strategic entry points even when not formally part of the curriculum. Sandy’s story provides insight into how educators can drive change within university campuses. Check out Sandy’s work: Healthy, Sustainable, and Equitable Food Strategic Plan at University of Tasmania, which can be found at the following link. https://www.utas.edu.au/about/sustainability/facilities-and-operations/food-and-gardens (https://www.utas.edu.au/about/sustainability/facilities-and-operations/food-and-gardens)

   Designing, supporting and using public policy for sustainable food systems - Part 1

   In this episode, we talk to dietitians who are using policy as a tool to facilitate increased uptake for healthy dietary patterns that support more sustainable food systems. We will explore shaping policy, utilizing policy, power, and empowerment, and examining evidence of impact. Key points we will explore include: The ways in which policy is integrated across scales, and how we can leverage that. A process, or framework, that you can use to analyze and address problems using systems thinking—the I+PSE framework How collaboration and structural empowerment can disrupt current ways of thinking. How to get started on policy work. Guests: Part 1: Angie Tagtow is a registered dietitian and nutritionist from the United States, whose career in public health spans decades and various scales. Angie has worked to increase the interconnectivity between agricultural, nutrition, and public health policies and to explicitly include sustainability-relevant evidence in food policy. Along the way, Angie has been a champion of educating dietitians and nutritionists on public policy and creating the advocacy structures and platforms to shape policy. Check out Angie’s work: The Individual plus Policy, System, and Environmental (I+PSE) Conceptual Framework for Action is a roadmap for RDNs across all areas of practice (eg, research, education, clinical, community, and management) to better address adaptive challenges and to formulate multidimensional strategies for optimal impact.
