The Claim
A 27 g/day increase in whole grain intake is associated with a 5.1% reduction in colorectal cancer risk and a 4.5% reduction in total cancer mortality risk.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who eat 27 grams more whole grains per day than the average Australian adult have a 5.1% lower risk of colorectal cancer and a 4.5% lower risk of dying from any cancer.
See the scientific wording
A 27 g/day increase in whole grain intake, equivalent to the gap between current Australian adult consumption (21 g/day) and the recommended Daily Target Intake of 48 g/day, is associated with a 5.1% reduction in colorectal cancer risk and a 4.5% reduction in total cancer mortality risk, based on pooled data from dose-response meta-analyses of prospective observational studies.
Eating more whole grains delivers fiber that reaches the gut unchanged, where bacteria break it down into special acids. These acids feed the cells lining the colon, strengthen the barrier that keeps harmful substances out, and reduce swelling in the tissue. This lowers the chance of damaged cells turning into cancer.
What the research says
1 studyEating about one extra serving of whole grains each day (27 grams more) is linked to a small but real drop in the chance of dying from colon cancer and other cancers, and this study confirms that by using data from many long-term health studies.
