The Claim
Higher dietary fiber intake, as measured by detailed 4- to 7-day food diaries, is associated with a 34% lower odds of developing colorectal cancer in adults when comparing the highest to the lowest quintile of fiber intake density (odds ratio: 0.66, 95% CI: 0.45–0.96), after adjustment for age, weight, smoking, education, physical activity, alcohol, folate, and red meat intake.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adults who consume more dietary fiber, based on detailed food records, have a lower statistical likelihood of developing colorectal cancer compared to those with the lowest fiber intake, even after accounting for other lifestyle and dietary factors.
See the scientific wording
Higher dietary fiber intake, particularly when measured by detailed 4- to 7-day food diaries, is associated with a 34% lower odds of developing colorectal cancer in adults when comparing the highest to the lowest quintile of fiber intake density (0.66 odds ratio, 95% CI: 0.45–0.96), after adjusting for age, weight, smoking, education, physical activity, alcohol, folate, and red meat intake, suggesting fiber may play a protective role in colorectal cancer risk.
What the research says
1 studyStudy: Dietary fiber and colorectal cancer risk: a nested case-control study using food diaries.
This study found that people who ate more fiber, as recorded in detailed food diaries, were much less likely to get colon cancer. It’s like keeping a food journal helped scientists see the real benefit of fiber that other methods missed.
