Could your diet change gut bacteria and raise colon cancer risk?
NCT ID NCT03550885
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how two different diets affect gut bacteria and markers linked to colon cancer risk in 15 African American adults at higher risk. Participants ate a high-fat, animal-based diet and a low-fat, plant-based diet for three weeks each. Researchers measured changes in gut bacteria and bile acids to understand the connection between diet and colon cancer risk.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
diet (high taurine and saturated fat vs. low taurine and saturated fat)
What this could lead to
If successful, this could help explain how certain diets increase colon cancer risk and point to dietary changes that lower that risk.
What could go wrong
This is a very small, early study with only 15 participants, so results may not apply to everyone. It looks at biological markers, not actual cancer outcomes.
