BMJ Stands by Teicholz Critique of DGAC Methods

Following a formal post-publication review , the BMJ (formerly British Medical Journal) decided against retracting Big Fat Surprise author Nina Teicholz's critical assessment of the Dietary Guidelines Advisory Committee (DGAC) process published last year. Teicholz took issue with methods employed by the DGAC to produce the scientific report underpinning the Dietary Guidelines for Americans. BMJ conducted the formal review in response to calls from advocacy groups, including the Center for Science in the Public Interest, urging BMJ to retract Teicholz's article. Individuals conducting the post-publication review, however, found that DGAC processes to protect against bias are inadequate, and that in some instances, methods in the DGAC scientific report lacked sufficient detail and circumvented systematic search processes. The reviewers concluded the composition of the DGAC and its conflict of interest policies and work group structure require further investigation. In addition, the reviewers found that the Nutrition Evidence Library and DGAC do not appear to have incorporated key developments in methodology and governance of evidence-based guideline development since 2010, though they did offer some corrections and clarifications to the original article.
