First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

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.
