Scientists use labeled wheat bran to uncover gut secrets
NCT ID NCT03717311
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This pilot study gave 6 healthy women a breakfast containing wheat bran with a special carbon label (13C) to track how it is fermented in the gut. Over 24 hours, researchers collected breath, urine, blood, and stool samples to measure breakdown products. The goal is to identify new biomarkers that reflect fiber digestion, which could lead to better dietary advice in the future.
