I’m doing a prerecorded online presentation to the V Congresso Nacional de Alimentos e Nutrição, Universidade Federal de Ouro Preto, at 8:00 p.m. on my book Unsavory Truth (Um Verdade Indigesta). Information about the conference is here. It runs from October 4 to 8.
The strange story of my accepted but then unpublished commentary on a Disney-sponsored study
Last summer, Brian Wansink, a friend and Cornell colleague and the editor of the new Journal of the Association for Consumer Research, asked me to write a commentary on a paper to be published in its inaugural issue.
The paper turned out to be by a group of authors, among them John Peters and Jim Hill, both members of the ill-fated Global Energy Balance Network, the subject of an investigation by the New York Times last August.
Titled “Using Healthy Defaults in Walt Disney World Restaurants to Improve Nutritional Choices,” the paper described the benefits of improving the composition of kids’ meals at Disney World.
The healthy defaults reduced calories (21.4%), fat (43.9%) and sodium (43.4%) for kid’s meal sides and beverages sold in the park. These results suggest that healthy defaults can effectively shift food and beverage selection patterns toward healthier options.
The authors explain:
This work was supported by the Walt Disney Company and by the National Institutes of Health…The Walt Disney Company and the National Institutes of Health had no role in the design, analysis, or writing of this article. Full disclosure: JH is a consultant for the Walt Disney Company and for McDonalds; KA is a consultant for the Walt Disney Company.”
I thought Disney’s sponsorship of this research and its withholding of critical baseline and sales data on kids’ meals that the company considered proprietary did indeed deserve comment, and wrote my piece accordingly. Brian Wansink soon accepted it for publication but to my surprise, gave it to Peters et al. for rebuttal. They filed a lengthy response. I was then given the opportunity to respond, and did so, briefly.
The paper by Peters, et al. did was published in the journal’s first issue. This issue also includes several commentaries on other papers (none of which are accompanied by rebuttals).
My commentary—and the back-and-forth—however, were omitted.
After some discussion, the journal published my commentary online. You have to scroll down to find it. The site provides no links to it in the table of contents or in the article by Peters et al.
Is it possible that Disney or the authors’ contractual relationships with Disney could have had anything to do with the omission of my accepted-for-publication commentary? Brian Wansink says no, they just ran out of room (despite room for others).
Here’s what I wrote:
Dietary nudges for obesity prevention: They work, but additional policies are also needed
In 2006, the Walt Disney Company announced a new initiative to improve the nutritional quality of meals served to children at its theme parks. The company would be changing the default kids’ meals—the components that come without having to be ordered separately–to include low-fat milk, juice, or water rather than soft drinks, and sides such as apple sauce or carrots rather than French fries. Parents who wanted sodas or fries for their children would have to ask for them, something many might not bother to do. Health groups had long advocated for this policy change (Wootan 2012).
As I commented to a reporter at the time, “going to Disney World is an excuse for eating junk food…Disney or its advisers must be feeling they have some responsibility” (Horovitz and Petrecca 2006). Indeed, the healthier defaults were part of a larger effort by Disney to deal with its contribution to obesity in America. After ticket prices, food is the second greatest source of revenue at Disney World. Although reducing the amount of food consumed at the parks might help create a less “obesogenic” food environment, revenues might fall. But the default change might be revenue neutral. By 2008, Disney could report that two-thirds of U.S. customers ordering kids’ meals had accepted the default, with no loss in sales. In Hong Kong Disney parks, nearly all customers accepted the default. The report, however, did not include data on the numbers or proportions of customers ordering kids’ meals (Walt Disney Company 2008).
Disney’s more recent summary of its child health initiatives states that it is funding investigators at the University of Colorado to conduct a more formal evaluation of use of the default options (Walt Disney Company 2015). The paper by Peters et al. (2016) in this issue of the Journal presents the results of that research. Their work confirms the ongoing effectiveness of the strategy. Nearly half the customers ordering kids’ meals accepted the healthy default side dishes and two-thirds accepted the healthier beverages. These choices resulted in significant reductions in the calories, fat, and sodium in purchased kids’ meals, but not sugar (Peters et al 2016).
The authors argue that gentle nudges changes like these are preferable to more coercive policies that smack of nanny statism. Such reductions help, but are they enough to make a real difference? To answer this question, it would help to know what else the children were eating along with the drink and side dishes. Although the authors were given raw sales data, Disney did not permit them to use this information as part of the overall analysis. The company also refused to provide information about the number of children who visited the park or the number of kids’ meals sold.
These missing pieces raise red flags because this is a Disney-funded study that produced results that Disney can use to advertise itself as a company that cares about kids’ health, and to deflect attention from Disney World’s’ reputation as a junk-food paradise. Corporate funding of research introduces conflicts of interest and reduces the credibility of the results, not least because the biases inherent in such research are largely unconscious, unintentional, and unrecognized (Moore et al 2005) The results of this study merit especially careful scrutiny. Taking them at face value, the default strategy worked well for the drink, but the sides are still a problem, and so are the sugars. They do not reveal much about what kids eat in a day at Walt Disney World
Nudges like this default are an important part of strategies to counter childhood obesity. But are they enough to deal with the public health problem? To make a real difference, they need to be accompanied and supported by a range of policy approaches. Current thinking about such approaches recommends combining insights from behavioral research, economics, and public health to establish a food environment far more conducive to making the healthy choice not only easy choice, but also the preferred choice. Doing so is likely to require multiple actions—for example, regulation of nutrient content and marketing; incentives such as subsidies of healthier foods; disincentives such as taxes, warning labels, and nutritional rating systems for unhealthier foods; and education of adults and children (Hawkes et al 2015). Disney’s voluntary default is a small step in the direction of such policies, but many more are needed if we are to make real progress in reducing the prevalence of childhood obesity.

And here’s my response to the rebuttal by Peters et al.
The response from Peters and Hill still fails to acknowledge the severity of the problems posed by Disney’s sponsorship of their research—the company’s failure to produce data essential for proper interpretation of study results, and the level to which sponsorship by food companies biases such interpretations. At one point, Disney boasted of the results of this research, confirming its benefit to marketing goals. The threat of industry sponsorship to research credibility has received considerable press attention in recent months, as must surely be known to these authors.1,2
