The Claim

Dietary fiber intake density (grams per megajoule of energy) is inversely associated with colorectal cancer risk, with a 17% lower odds of colorectal cancer per 0.7-g/MJ increase in fiber intake density (OR = 0.83, 95% CI: 0.70–0.97), indicating that fiber intake relative to total energy intake may be a stronger predictor of risk than absolute fiber intake.

Support is ahead, but a single strong opposing study can change this.

In plain English

People who consume more dietary fiber relative to their total energy intake have a lower risk of developing colorectal cancer compared to those with the same amount of fiber but higher overall calorie intake.

See the scientific wording

Dietary fiber intake density (grams per megajoule of energy) shows a stronger inverse association with colorectal cancer risk than absolute fiber intake, with a 17% lower odds per 0.7-g/MJ increase (OR = 0.83, 95% CI: 0.70–0.97), suggesting that fiber intake relative to total energy may be a more accurate indicator of protective dietary patterns.

What the research says

1 study
  1. Study: Dietary fiber and colorectal cancer risk: a nested case-control study using food diaries.

    This study found that people who ate more fiber relative to how much food they consumed had a lower risk of colon cancer, and this was a better predictor than just counting total fiber. So, it’s not just how much fiber you eat, but how much fiber you eat compared to your overall food intake.
