to the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. We also support Stanton and colleagues’ call for further clarification, justification, or reconsideration of the theoretical minimum risk exposure level of zero for unprocessed red meat selected by GBD in their latest estimates. Not only does the increase in the estimated burden appear implausible, but the lack of transparency in the assumptions underlying the calculations undermines the authority of the GBD estimates.
Further, insufficient clarity of such assumptions potentially reduces their use within policy development.
Removing meat from such diets is impractical and unrealistic, and carries a risk of nutritional deficiency judged to outweigh future cancer risk.
The absence of an explicit rationale for the assumptions underlying the GBD estimates is troublesome, unsupported by the evidence, and unrealistic.
We declare no competing interests.
