Dietary Fiber Intake Reduces Risk for Colorectal Adenoma

March 6, 2014

Reporting in Gastroenterology, Qiwen Ben and colleagues find that high dietary fiber intake is associated inversely with colorectal adenoma risk. Further studies are warranted.

Reports on the association between dietary fiber intake and risk of colorectal adenoma (CRA), the precursor of colorectal cancer, have been inconsistent. Qiwen Ben and colleagues conducted a meta-analysis of case-control and cohort studies to analyze this association. Reporting in Gastroenterology, they find that high dietary fiber intake is associated inversely with CRA risk. Further studies with prospective designs that use validated questionnaires and control for important confounders are warranted.
