Dietary Fiber and Whole Grains Reduce CRC Risk
According to study published in this week's issue of the British Medical Journal, a high intake of dietary fiber — in particular cereal fiber and whole grains — is associated with a reduced risk of colorectal cancer (CRC). Doctors from the U.K. performed a systematic review and meta-analysis of prospective observational studies. The summary relative risk of developing CRC for 10g daily of total dietary fiber was 0.9, for fruit fiber it was 0.93, for vegetable fiber it was 0.98, for legume fiber it was 0.62 and for cereal fiber it was 0.90. The team found that the summary relative risk for an increment of three servings daily of whole grains was 0.83. Further studies should report more detailed results, including those for subtypes of fiber and be stratified by other risk factors to rule out residual confounding. Further assessment of the impact of measurement errors on the risk estimates is also warranted.
