A newly discovered archive of documents reveal the sugar industry’s efforts to shape the national research agenda away from the effects of sugar on tooth decay and push for programs to focus on alternatives to reducing consumption. We spoke to Cristin Kearns, a University of California, San Francisco postdoctoral scholar who discovered the papers, about her research, how the agenda of the National Institute of Dental Health became aligned with the sugar industry’s, and how industry can subvert research agendas to protect their economic interests at the expense of public health.
