Overview
The central objective of this proposal is to test a novel diet capable of meeting the elevated protein requirements in ulcerative colitis (UC), while simultaneously decreasing microbial hydrogen sulfide (H2S) production in the colon with fiber.
Interventions
- Other High Protein, High Fiber (HPHF) Diet
The HPHF diet is a diet designed to maximize the intake of proteins and fermentable dietary fibers. Frozen meals are provided to participants weekly and consumed over two non-consecutive 7-day periods.
Primary outcome measures
- Fecal H2S Production [Time frame: Week 4]
