E236: Why we need a new food labeling system

April 29, 2024

The first nutrition labels mandated by the Food and Drug Administration appeared on food packages in 1994. A key update occurred in 2016, informed by new science on the link between diet and chronic disease. Along the way, things like trans fats and added sugars were required, but all along, the labels have been laden with numbers and appear on the back or side of packages. There has long been interest in more succinct and consumer-friendly labeling systems that might appear on the front of packages. Such systems exist outside the US, but for political reasons and lobbying by the food industry, have been blocked in the United States. There’s new hope, however, described in a recent opinion piece by Christina Roberto, Alyssa Moran, and Kelly Brownell in the Washington Post. Today, we welcome Dr. Christina Roberto, lead author of that piece. She is the Mitchell J. Blutt and Margot Krody Blutt Presidential Associate Professor of Health Policy in the School of Medicine at the University of Pennsylvania.

E235: A successful interactive obesity treatment approach

April 22, 2024

Traditional clinical weight loss interventions can be costly, time consuming, and inaccessible to low-income populations and people without adequate health insurance. Today’s guest, Dr. Gary Bennett, has developed an Interactive Obesity Treatment Approach, or iOTA for short, that represents a real advance in this area. Dr. Bennett is Professor of Psychology and Neuroscience, Medicine and Global Health at Duke University, where he is also Dean of Trinity College of Arts and Sciences.

E233: Grocery and meal insight from the Baby’s First Years project

March 28, 2024

A growing number of research studies show that the cognitive and brain development of low-income children differs from that of children in higher income families. For any family, that is a concerning statement. Today’s podcast features a project called Baby’s First Years, a multi-year effort to test the connections between poverty reduction and brain development among very young children. Here to talk about what the study has revealed so far is Dr. Lisa Gennetian from Duke University’s Sanford School of Public Policy, and Dr. Sarah Halpern-Meekin from the La Follette School of Public Affairs at the University of Wisconsin, Madison.

E230: Results from a national consumer attitudes survey on dollar stores

February 22, 2024

Dollar stores are the fastest growing food retailer in the United States, both by sheer number of stores and consumer food purchases. Just two corporations, Dollar General and Dollar Tree, which also owns Family Dollar, operate more than 35,000 stores across the country. However, a growing body of research reveals that dollar stores offer limited healthy food options. Dollar stores shape the food environments of communities, especially in the South and Midwest regions and communities in rural areas with substantial shares of Black and Latin people and households with limited financial resources. What do we know about the impact dollar stores have on these communities and the overall wellbeing of community members? The Center for Science in the Public Interest conducted a national survey to understand how people perceive and actually use dollar stores. Today we will talk with lead author of this study, Senior Policy Scientist Sara John.

E223: Food Policy Lessons from Removing Trans Fats from our Diet

December 20, 2023

In August of 2023, the Food and Drug Administration issued something known as a direct final rule, disregarded trans fats in the food supply. Consumers won’t notice changes as the rule just finalizes FDA’s 2015 ruling that partially hydrogenated oils – trans fats – no longer had “GRAS status.” GRAS stands for generally regarded as safe. We cover this issue today because this trans fat ban was the product of lots of work by a key group of scientists, the advocacy community, and others. The anatomy of this process can teach us a lot about harnessing scientific discovery for social and policy change. At the center of all this is today’s guest, Dr. Walter Willett. Walter Willett is one of the world’s leading nutrition researchers. He is professor of epidemiology and nutrition at the Harvard T.H. Chan School of Public Health, and for many years served as chair of its Department of Nutrition. He’s published extensively, been elected to the National Academy of Medicine, and it turns out, is the world’s most cited nutrition researcher.

E221: Understanding Poverty, Wellbeing, and Food Security for US Children

November 30, 2023

As the parent of a 12-year-old child, I know that raising a child is one of the most profound and rewarding experiences of a person’s life. It is also shockingly expensive. The high cost of child rearing is particularly difficult for families with limited resources. To help us think through this issue, it is my great pleasure to welcome a colleague here at Duke: Dr. Christina Gibson-Davis, Professor of Public Policy. Christina studies economic inequality, and particularly how it affects families with children.

E217: When babies inherit Mom’s trauma-affected gut microbiome

October 12, 2023

A diversity of bacteria and microorganisms making up the gut microbiome supports both our physical and our mental health. Research has shown that stress and trauma can negatively impact the microbiome. But a recent study took that finding to a new level. This was a study published in the Proceedings of the National Academy of Sciences. Scientists now see inflammation-related microbiomes in babies born to women who experienced mistreatment or adversity during their own childhood. These microbiomes predispose children to physical and mental health problems. We’ll talk today with the co-author of that paper, Fran Querdasi, from the University of California, Los Angeles.

E216: Who are the biggest beef eaters of all?

October 5, 2023

I read a study recently featuring a term I had not heard or seen before: “disproportionate beef eaters.” The study was done by Dr. Amelia Willits-Smith, Diego Rose and colleagues at Tulane University. So, who are such beef eaters and how are their consumption patterns associated with environment and climate change? Today we’re joined by one of the authors of that study, Dr. Diego Rose, who is a professor and nutrition program director in the School of Public Health at Tulane.

E214: Championing MyPlate – USDA’s Director of Food & Nutrition Service Caree Cotwright

September 13, 2023

Our guest today is Dr. Caree Cotwright, director of Nutrition Security and Health Equity at the Food and Nutrition Service at the US Department of Agriculture. Dr. Cotwright is leading a USDA-wide approach to advancing food and nutrition security in the United States. Part of her responsibility includes the charge from Secretary of Agriculture Tom Vilsack to make MyPlate a household name. MyPlate is the official visual reminder of the US government to make healthy food choices from each of the five food groups. Now, this turns out to be a tall but important order. About a quarter of US adults have heard of MyPlate, according to a recent survey.
