Prominent nutrition researcher resigns from NIH over scientific censorship
Kevin Hall, a prominent nutrition expert who led influential studies on ultra-processed foods, has resigned from his long-held position at the National Institutes of Health, alleging censorship of his research by top aides of health secretary Robert F. Kennedy Jr.
In a post on LinkedIn, Hall claimed that he “experienced censorship in the reporting of our research because of agency concerns that it did not appear to fully support preconceived narratives of my agency’s leadership about ultra-processed food addiction.”
In comments to CBS News, Hall said the censorship was over a study he and his colleagues recently published in the journal Cell Metabolism, which showed that ultra-processed foods did not produce the same large dopamine responses in the brain that are seen with use of addictive drugs. The finding suggests that the mechanism leading people to overconsume ultra-processed foods may be more complex than the studied mechanisms in addiction. This appears to slightly conflict with the beliefs of Kennedy Jr., who has claimed that food companies use additives to make ultra-processed foods addictive.
