Description
1 study reviewed
In plain English

Australian adults eat an average of 21 grams of whole grains per day, and 73% of them eat less than the recommended 48 grams per day.

See the scientific wording

Current median whole grain intake among Australian adults is 21 g/day, with 73% of the population consuming less than the recommended Daily Target Intake of 48 g/day, indicating widespread dietary shortfall.

Why this might work

When people eat whole grains, the fiber and starches in them pass through the stomach and small intestine without being broken down. In the colon, bacteria break down these compounds and produce short-chain fatty acids. These fatty acids feed the cells lining the colon, strengthen the barrier between the gut and the rest of the body, and reduce inflammation. This lowers the chance that damaged cells in the colon turn into cancer.

  1. Study: Whole Grain Intakes Are Associated with Healthcare Cost Savings Following Reductions in Risk of Colorectal Cancer and Total Cancer Mortality in Australia: A Cost-of-Illness Model

    This study found that most Australians eat way less whole grain than doctors recommend — about 21 grams a day instead of the 48 grams they should be eating. That matches exactly what the claim says.
