Summary

This study looks at how eating different amounts of cysteine—a protein building block—affects gut bacteria and inflammation in people at higher risk for colon cancer. Researchers will compare Black and White adults aged 45-75 who have had colon polyps. Participants will follow both a high-cysteine and a low-cysteine diet for three weeks each, and provide blood, stool, and saliva samples to measure inflammation and gut microbes.

What this could mean

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

Active substance: Low Cysteine Diet and High Cysteine Diet
What this could lead to: If successful, this study could reveal how diet and gut bacteria contribute to colon cancer risk differences between Black and White populations.
What could go wrong: This is a small, early-stage observational study with only 40 participants. It does not test a treatment, so results may not lead to direct health changes.
