About this study
The goal of this clinical trial is to learn whether consuming a high fermented food diet improves bowel function and gut health in adults with chronic spinal cord injury (SCI). The study will also evaluate the feasibility and tolerability of consuming fermented foods daily for 10 weeks. The main questions it aims to answer are: 1. Does a high fermented food diet improve neurogenic bowel dysfunction symptoms and colonic transit in adults with SCI? 2. Does fermented food intake change gut microbiome composition, short-chain fatty acid production, and intestinal inflammation? Researchers will compare a high fermented food diet to a control diet to evaluate effects on bowel health and gut microbiome outcomes. Participants will: * Consume study foods daily for 10 weeks * Attend 2 in-person study visits * Collect stool samples at home and ship them overnight to the research team using provided collection kits and prepaid shipping materials * Complete bowel health questionnaires and dietary recalls * Undergo Sitz marker testing with abdominal X-rays to assess colonic transit * Participate in biweekly monitoring contacts throughout the study period
