As stated75 vegans and 75 omnivorous Danes

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.
Claim 2 of 5Not checkedThe researchers found that gut bacterial diversity was, on average, lower among vegans than among omnivores.View evidenceHide evidence
As statedon average
Not checked
A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.
Claim 3 of 5Not checkedThe lower average diversity among vegans may be linked to their lower protein intake, because vegans who consumed the most protein had biodiversity levels comparable to those of omnivores.View evidenceHide evidence
As stated12% of dietary energy from protein in vegans versus 17% in omnivores
Not checked
A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.
Claim 4 of 5Not checkedApart from reduced diversity, the vegan group was described as having a health-promoting gut microbiome, with more fiber-degrading bacterial species, more Blastocystis, lower blood glucose and cholesterol, and fewer inflammatory markers.View evidenceHide evidence
Not checked
A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.
Claim 5 of 5Not checkedThe researchers said the study was relatively small and observational, so it can point to associations but cannot establish that protein intake or other dietary habits directly cause changes in gut microbiome or gut health.View evidenceHide evidence
