Conflict of interest in nutrition conference financing: Moving towards solutions after IUNS 2022

Making contributions to reducing malnutrition entails sharing evidence and approaches among the research and practice communities, including through conferences. But who is involved in these processes, including who pays, matters both in terms of actions and optics. This paper was motivated by observations – in 2022 and historically – that the International Union of Nutritional Sciences (IUNS), in putting on its flagship International Congress of Nutrition (ICN), was leaving itself – and, by extension, participating scientists – open to conflicts of interest (COI). With contemporary scholarship on the commercial determinants of health making clear the ways in which this kind of sponsorship represents both a conflict of interest for nutrition events and a negative force in broader food system drivers of nutrition, this paper aims to document the issues surrounding the 2022 IUNS-ICN conference as historical record; draw on academic literature on conflict of interest to better understand the issue; and suggest some practical options moving towards COI-free nutrition events in the future.
