    E236: Why we need a new food labeling system
    May 2 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. Interview Summary This is a really important topic, and if the nation gets this right, it really could make a difference in the way people make product decisions as they're in the supermarket. So, let's talk first about the importance of labeling on the front of the package. Why is that important when all the information is somewhere else, namely on the side or the back? I think there's a couple of key reasons why it's good to do front of packaging food labeling specifically. So, as you mentioned, it was a huge deal in 1994 to get this information mandated to be on food packaging to begin with, right? All of a sudden, there was much more transparency about what's in our food supply, but that being said, when you think about the nutrition facts label, it's pretty dense. There's a lot of percentages, there's a lot of numbers, there's a lot of information to process. And when people are actually in the supermarket shopping, they're making these split-second decisions, right? So, it's not to say that some consumers are turning it around and inspecting that packaging, but the reality is, for most people, it's a very habitual behavior. And so, we want to be in a place where that information is prominent, it's easily accessible, and it's easy to understand so that when you're making those snap judgements, they can be informed judgments. So, you're not talking about taking what's on the back and just moving it to the front. You're talking about a different set of information and symbols that might be available? That's right. Yeah. What front of package labeling is designed to do is just take some of the key bits of information that we know from science is going to be most important for consumers to base their nutritional decisions on. That's things like saturated fat, sodium, added sugars, right? And moving that to the front of the package and communicating about it in a very simple, clear way. So, no numbers, no percentages, just very straightforward language. And ideally some sort of icon, like an exclamation point, that would draw attention to that symbol and just quickly let consumers know that this product is high in those nutrients that you need to be concerned about and you need to try to limit. Why is it an important time to be thinking about this issue in the US? It's an important and it's an exciting time because the FDA right now is highly interested in actually moving forward on a policy that would require these types of front of package labels. And that hasn't been true, as you noted, for about a decade. But last year, the White House convened a very significant conference that hadn't happened in 50 years about nutrition, health, and hunger. And front of package labeling actually made it into their report in that conference as a key objective for this country in terms of a food policy that, under the Biden administration, they want to achieve. What we're seeing the FDA do now is actually undertake a series of research studies to try to understand what should this label look like, and how should it be designed to be consumer friendly. With the hope that actually we'll get a proposed rule on this potentially by June, and even if not by June. There's clear momentum that it looks like this is going to be happening in the near future. In a few minutes, I'd like to ask you about what's taken place in other countries, but what's been the history of this in the US? Front of package labeling really came to a head back in 2009. And it's actually quite a delight to share this with you, Kelly, because you and I were doing some research around it at the time. So, what played out then is a labeling system was introduced called Smart Choices. At its face, it seemed to make sense, right? It was going to be a check mark that was going to be put on products that were deemed to be healthy as a smart choice. So, a consumer could look at that and select something they wanted to eat that was relatively healthy. The ...

    E235: A Successful Interactive Obesity Treatment Approach
    Apr 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. Interview Summary You know, in this time when people are talking about more expensive, and kind of more intrusive interventions, like the big weight loss drugs, it's nice to know that there may be alternatives that could be accessible to more people. Could we start off with you telling our listeners what the iOTA approach is and how it works? Sure. This is an approach for weight management. It's useful for weight loss or preventing weight gain or maintaining one's weight after you've lost weight. The idea here is that it's a technology that's designed to be highly accessible, and useful for a range of different types of populations. So, as you described, we have developed and tested this primarily for folks who are medically vulnerable, who are low income, who are racial, ethnic minority, who live in rural communities, and where we have traditionally had real difficulty reaching populations with effective weight loss tools. So, iOTA is a fully digital approach. It uses technologies smartphone apps, but it can also use text messaging, interactive voice response, those are like robocalls, automated telephone calls, websites. We've tested this on a wide range of different types of technology platforms, and we've tested it in a range of different types of populations all over the country and indeed even in other countries. So, give us some examples of what kind of information people might be receiving through these various forms of media. The underlying kind of technology, the underlying approach, I should say, for iOTA is actually reasonably simple. It operates from the perspective that creating weight loss is really about making an energy deficit. That is to say, helping people to consume fewer calories than they are expending. The realization we had years ago is that you can get there, you can create that calorie deficit in a whole host of different ways. Some people diet, some people try to get more active, there are limitations around that kind of approach. But fundamentally, you can also just get there by asking people to do some reasonably straightforward behaviors. Like not consuming sugary beverages, or consuming fewer chips, cookies and candies. Or changing the amount of red meat that they put on the plate. And, if you frame those things out as goals, then you can prescribe those goals to people in ways that make sense to them personally. The trick though is actually in the idea of personalizing those goals to the given individual. And that's where technology comes in and gets very helpful. The case is, if you have a large library of these goals, you'd want to try to provide these in a highly personalized way. That really are aligned with what people's needs are and noting that those needs may change over time. So, what we do with iOTA is deliver a very short survey. That survey then helps us to be able to look into our library of goals and pick the ones that are most useful for our users. We prescribe those goals, and then we ask folks to self-monitor those goals. Self-monitoring or tracking is an extraordinarily powerful part of behavior change science. And so, we ask them to track using one of our technologies: the chat bot or the text message or interactive voice response or the smartphone app. Every time that we receive data from one of our users, we give them highly personalized feedback that is designed around principles of behavior change science. And then over time we also give them support. We do support sometimes from a coach or sometimes from a layperson, sometimes it's even from a physician. And over time what we find is that this kind of an iOTA approach helps people to lose weight, prevent weight gain, have weight loss maintenance, but it also has a cascade of other types of effects, some of which we didn't really even anticipate producing. This reminds me of something that I've fought for years, that nutrition and weight control can get incredibly complicated and down on the weeds in a fascinating way from a academic point of view. But that you can get to the goal line with just a few simple things. You might be 80% to the goal line just by eating less junk food and eating more fruits and vegetables and getting mired in that last 20% becomes confusing. It sounds like that's exactly what you're doing. That you kind of picked some of the big things that people can do, establish goals around them, and then provide a behavioral path for getting to those goals. That's precisely our thinking. And the ...

    E234: White Burgers, Black Cash - a history of fast food discrimination
    Apr 8 2024
    Fast food is part of American life. As much a part of our background as the sky and the clouds. But it wasn't always that way, and over the decades, the fast food landscape has changed in quite profound ways. Race is a key part of that picture. A landmark exploration of this has been published by today's guest, Dr. Naa Oyo Kwate. She is an Associate Professor in the Department of Africana Studies and the Department of Human Ecology at Rutgers University. Her book, recently published, is entitled White Burgers, Black Cash: Fast Food From Black Exclusion to Exploitation. The book has been received very positively by the field. And was recently named the best book in the field of urban affairs by the Urban Affairs Association. Interview Summary I was so happy to see your book because people have talked about the issue of race off and on in the field, but to see this kind of scholarly treatment of it like you provided has been really a welcome addition. Let me start with a general question. Let's begin with the fast food situation today and then rewind to where it began. Are there patterns to where fast food restaurants are located and who fast food is marketed to? Absolutely. There's quite a bit of research, and you just alluded to the work that's been done in the field. There's a lot of research that shows fast food is most dense in African American communities. Not every study has the same finding, but overall that's what the accumulated evidence shows. On the one hand you have the fact that Black communities are disproportionately saturated with these outlets. Then there's also the case that apart from the physical locations of the restaurants, fast food is strongly racialized as Black in terms of how it's portrayed to the public. It [Fast Food] relies on images of Blackness and Black cultural productions such as Black music for its marketing. These sometimes these veer into racial caricature as well. One of the things I talked about in the book briefly is the TV commercial character Annie who Popeye's introduced in 2009. They basically created this Black woman that Adweek at the time was calling "feisty," but it's really just this stereotypical idea of the sassy Black woman and she's in the kitchen frying up the chicken for Popeye's. And actually, some of the language that was used in those commercials really evokes the copy on late 19th century and Aunt Jemima pancake mix packaging. It's a really strong departure from fast food's early days, the way that fast food is now relying on Blackness as part of its core marketing constructs. I'm assuming that it follows from what you've been saying that the African American community has disproportionately been targeted with the marketing of these foods. Is that true of children within that community? Research shows that in terms of fast food marketing at the point of purchase. There's more - display advertising for example at restaurants that are in Black communities. And then there's also been research to show, not in terms of the outlets themselves, but in terms of TV programming that there tends to be more commercials for fast food and other unhealthy foods during shows that are targeting Black youth. How much of the patterning of the fast food restaurants is due to income or due to the amount of fast food consumption in these areas with many restaurants? Almost none of it really. It's not income and it's not the amount of fast food that people are consuming. In fact, one of the main studies that led me to start researching this book, because I was coming to it from public health where there was a lot of research around the disproportionality of fast food restaurants. We actually did a study in New York City, some colleagues and we published it in 2009, where we looked at how fast food was distributed across New York City's five boroughs. And restaurant density, we found, was due almost entirely to racial demographics. There's very little contribution from income. So, the percentage of Black residents was what was driving it. That was the biggest predictor of where fast food was located. It wasn't income, income made very little contribution and if you compared Black neighborhoods that were higher in income to those that were lower in income, they basically had about as much fast food exposure. Then if you compare them to white neighborhoods matched in income, Black neighborhoods still had more. So, it wasn't income, it was race. There are other areas that were high in fast food density like Midtown and downtown Manhattan where you have commercial and business districts, transportation hubs, tourist destinations. So, you expect fast food to be in these really dense and kind of busy commercial areas, but the only residential space that had comparable density were Black and brown neighborhoods. The assumption that many people have is that, okay, well if it's not income, then it's probably demand. So probably fast food is just dense in those ...
