Role of Diet in Colorectal Cancer Incidence: Umbrella Review of Meta-analyses of Prospective Observational Studies.

ABSTRACT:

Importance

Several meta-analyses have summarized evidence for the association between dietary factors and the incidence of colorectal cancer (CRC). However, to date, there has been little synthesis of the strength, precision, and quality of this evidence in aggregate.

Data sources

MEDLINE, Embase, and the Cochrane Library were searched from database inception to September 2019.

Evidence review

Only meta-analyses of prospective observational studies with a cohort study design were eligible. Evide
