Nov. 20 | 11:00 am – 12:00 pm

This free webinar will explore the U.S. Department of Agriculture’s (USDA) annual survey of household food security, and how it informs the work of different organizations in the U.S. Since the mid-1990s, USDA has reported on household food insecurity in the U.S. and at the state level. The Trump administration announced it is canceling the annual survey and will release a final report covering 2024 data in October 2025. The USDA reports and data are key to policy discussions on the health and well-being of Americans. Researchers, clinicians, and policymakers have used this information as an indicator of the impact of poverty, to assess the effectiveness of federal programs like the Supplemental Nutrition Assistance Program (SNAP), and to understand the contributions and limitations of the charitable food sector.

In this webinar, we will discuss how the nation’s largest food bank network uses USDA household food security data to report on Map the Meal Gap nationally; share work the Greater Boston Food Bank has led in assessing food insecurity and the charitable food sector in Massachusetts; and highlight economic research that uses these data to inform federal policy.

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.

Van Tulleken details his own month-long experiment consuming UPFs, resulting in significant weight gain and various health issues. He explains the scientific definition of UPFs, their industry-driven design to enhance addictiveness, and the broader implications on public health. The conversation delves into the addiction potential of UPFs, their effect on brain chemistry, and the critical need for policy change to address these issues. Hosted by Kelly Brownell, this episode offers a thorough, eye-opening exploration of why we can't stop eating food that isn't really food.

Bridging to Better Policy

The World Food Policy Center is a research, education, and convening organization at Duke University’s Sanford School of Public Policy. Center programs and activities focus on scalable food system practices and policies in support of a) equitable food-oriented economic development, b) social justice, c) public health, and d) environmental sustainability. Through our work, we explore human perspectives at each stage of problem analysis, solution design, and testing. We strive to uncover historical drivers of inequality and to bridge disconnected areas of food-related policy and practice intentionally. And, we seek to enhance community health and wellbeing by learning from and connecting with the people most affected by food system challenges.

Our Vision

Our goal is to improve human wellbeing, environmental health, and equity through innovative food system policy and practice. To achieve this, we strive to:

Understand the unique challenges and characteristics of rural and urban food systems, and how to translate solutions between them

Advance the principles and strategies of equitable food-oriented development as a mechanism for disrupting inequality, and driving sustainability

Engage critical audiences and change agents in a deeper understanding of food systems challenges, research advances, and pilot solutions

Contribute to food policy improvement by educating the next generation of professionals through hands-on, applied research

Our Approach

We catalyze innovative thinking and coordinated action to change policy and practice across the food system. To do this, we intentionally bridge the worlds of academia, industry, philanthropy, non-profits, governance, community, and culture. We conduct work at the global, national, and local levels in Durham and rural North Carolina.

We strive to:

create teams that bring stakeholders and change agents into collaboration

seek out and learn from the lived experiences of high-risk populations

build the relationships and trust needed to engage as partners in solution ideation fully

analyze historical context and the present-day outcomes of past public policy and practice

research gaps in knowledge to cultivate resilient, data-informed, and systemic solutions and best bet recommendations

structure solutions to achieve social justice, and to nurture human and environmental interdependence

Our Values

Healthy food is a fundamental human right. Society has a responsibility to create a resilient and sustainable food system to meet the evolving needs of our local, regional, and global communities.

Food system solutions must also address the root causes. Systemic and intermittent poverty creates simultaneous issues with housing, healthcare disparity, underemployment, and food insecurity in communities and individual households.

Relationships drive change. Trust is the basis for confronting the past, building mutual understanding, and envisioning new opportunities. Change happens at the speed of trust.

Social justice work must be grounded in humility. Confronting and dismantling the structural inequality in our culture requires continuous self-reflection, a willingness to try and fail, and a patient and long-term commitment to change.

Community-driven, institution-supported collaborations create sustainability. When institutions support community leadership, community ownership promotes sustained progress.
