What the research says

1 study

  1. Study: High and low dietary fiber consumption and cancer risk: a comprehensive umbrella review with meta-meta-analysis involving meta-analyses of observational epidemiological studies

    The study looked at whether eating more fiber lowers cancer death risk and found the exact same 17% lower risk as the claim, so it supports the claim.
