There is 'convincing' evidence that fibre-rich foods can offer protection against bowel cancer, scientists claim.
The call was made by leading experts in the wake of analysis of the most current research on the disease.
Recent research, analysed by experts from Imperial College London, found that three servings a day of cereal, fibre and wholegrains reduce the risk of the disease.
The latest findings come after scientists said in 2007 that dietary fibre 'probably' cuts the risk.
The World Cancer Research Fund (WCRF), which commissioned the analysis, said it recommended people eat a plant-based diet including fibre-rich foods such as wholegrains, fruits, vegetables and pulses such as beans.
The report is part of the WCRF's Continuous Update Project (CUP) and updates the bowel cancer findings in its 2007 report, Food, Nutrition, Physical Activity and the Prevention of Cancer: a Global Perspective.
Overall, the new analysis adds 263 new papers on bowel cancer to the 749 that were studied as part of the 2007 report.
Professor Alan Jackson, Chair of the CUP expert panel, said: "Our review has found strong evidence that many cases of bowel cancer are not inevitable and that people can significantly reduce their risk by making changes to their diet and lifestyle.
"Because our judgments are based on more evidence than ever before, it means the public can be confident that this represents the best advice available on preventing bowel cancer."
