Abstract

Cancer prevention through dietary modification requires prioritizing scientific evidence for effective policymaking. This note cites a comprehensive umbrella review of 246 meta-analyses and meta-analyses to clarify dietary priorities based on the World Cancer Research Fund/American Institute for Cancer Research framework. The findings indicate “convincing” evidence for a protective role of dietary fiber against colon and breast cancer, and strong “probable” evidence for dairy, whole grains, fruits, and vegetables in reducing the risk of gastrointestinal and breast cancers. Given this strong evidence, actions such as reviewing public food procurement, allocating targeted subsidies to whole grains, dairy and fiber resources, improving nutritional labeling standards, and establishing a per capita consumption monitoring system for targeted food groups are recommended. These findings provide a strategic tool for reorienting and smartening current nutritional policies to reduce the national cancer burden by focusing on effective interventions. © 2026, Isfahan University of Medical Sciences(IUMS).
