Study after study has shown that consumption of sugar sweetened beverages poses clear health risk. So how have the big soda companies, Coke and Pepsi in particular, reacted to this news and to public health policies that have aimed to restrict their business dealings like marketing, labeling, and even taxes? A fascinating and important part of this history has been told in a new book by Dr. Susan Greenhalgh called Soda Science: Making the World Safe for Coca Cola. Dr. Greenhalgh is the John King and Wilma Cannon Fairbank Professor of Chinese Society Emerita at Harvard University. But hold on, what in the heck does China have to do all this? Well, we're about to find out. This will be a very interesting discussion. Interview Summary Let's begin by setting the context for your book, again, on soda science. Back in 2015, the New York Times published a major expose, written by Anahat O'Connor, and a critique of what was called the Global Energy Balance Network (GEBN), that was funded by Coca Cola. Could you explain what this network was? Sure. The GEBN was an international network of researchers that argued that the energy balance framework is the best approach for addressing the obesity epidemic. So that simple framework calls for balancing the energy in the number of calories consumed through eating with a number of calories burned through moving to achieve a healthy weight. While that sounds neutral in practice, in the early 2000s, Coke and the food industry at large, adopted energy balance as their motto. It had several advantages. One is under the banner of "energy balance," the industry and the scientists working with it could say that people could eat whatever they wanted and then exercise it off. Unfortunately, that doesn't work for most people. Second, in practice, the energy balance slogan was used to promote exercise as the priority solution. What the research shows about energy is that exercise helps, but the primary answer to the obesity issue is to eat fewer unhealthy foods. Now the third advantage to the energy balance framework is that talking about energy balance meant the companies and the GEBN didn't need to mention soda taxes, or other legislative and regulatory measures, that worked but that might hurt the industry. So, in my book, I call this body of ideas adopted by the GEBN and the food industry “Soda Science.” That's short for Soda Defense Science - a science created not so much to understand obesity, as to defend the profits of the soda industry. Okay, that all makes sense, and I totally agree with your interpretation of the science that food intake is much more important in the obesity epidemic, in particular, than physical activity. It's not that activity is unimportant, but to divert attention away from the dietary part of it is really a public health misdeed. But one can obviously see the benefit to the industry for making that diversion. So, in that 2015 article, it was highly critical of the conflicts of interest that had been created by the soda industry paying prominent scientists. What benefits did the company reap from making these payments and what happened after that article got published? The GEBN was the product of the 15 years that came before it, of gradually building up this soda science. The GEBN itself lasted only about a year, but during that 15-year period, the industry benefited by having fewer people, fewer specialists, fewer countries talking about soda taxes. But what happened after the GEBN was outed in the New York Times in late 2015 was Coca Cola was absolutely mortified. The revelation that the company had paid for industry-friendly science was just incredibly embarrassing. So, under absolutely withering criticism from scientists and the public, Coke stopped funding the GEBN, which of course led to its collapse. The company also took a major turn in its approach to obesity. Vowing to no longer single-handedly fund scientific research, and by publishing a long so-called transparency list of all the individuals and organizations it had funded over the last 15 years. So, those things helped, but Coke's reputation remains tarnished to this day. But meanwhile, as for the academic scientists behind the GEBN, they saw things differently. They continued to maintain that their science had not been affected by the 20 million dollars that Coke had promised to support their network. Of the four researchers who led the GEBN effort, two stepped down and found wonderful jobs elsewhere. They both have leadership positions in different universities. One retired and the fourth continues to work in his previous position. So, there was no single, discernible impact on these debates within the academy. I know some of the individuals involved. And by the way, I know a good bit of information available to understand what this network was doing came from Freedom of Information requests that various parties made. And your book contains transcripts from emails and things ...
