Nutrition research is among the most contentious fields of science. Although the totality of an individual’s diet has important effects on health, most nutrients and foods individually have ambiguously tiny (or nonexistent) effects.1 Substantial reliance on observational data for which causal inference is notoriously difficult also limits the clarifying ability of nutrition science. When the data are not clear, opinions and conflicts of interest both financial and nonfinancial may influence research articles, editorials, guidelines, and laws.2 Therefore, disclosure policies are an important safeguard to help identify potential bias. In this Viewpoint, we contend that current norms for disclosure in nutrition science are inadequate and propose that greater transparency is needed, including a broader definition of what constitutes disclosure-worthy information.
