Summary

This study tests whether eating more plants and fewer animal foods can lower colorectal cancer risk. Researchers will measure changes in bile acids, gut bacteria, and other markers in 40 adults who have had colon polyps removed. Participants follow a self-guided diet for several weeks, and the team compares stool and blood samples before and after the diet change.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: increased plant-based diet and decreased animal-based diet
What this could lead to: If it works, this could point toward a simple dietary approach to help prevent colorectal cancer in people who have had polyps removed.
What could go wrong: This is a very small early trial with only 40 participants and no control group, so results may not be conclusive or apply to everyone. Dietary changes can be hard to maintain long-term.
