Association of Industry Sponsorship With Outcomes of Nutrition Studies

Although industry-sponsored studies were more likely to have conclusions favorable to industry than non-industry-sponsored studies, the difference was not significant. There was also insufficient evidence to assess the quantitative effect of industry sponsorship on the results and quality of nutrition research. These findings suggest but do not establish that industry sponsorship of nutrition studies is associated with conclusions that favor the sponsors, and further investigation of differences in study results and quality is needed.
