Ulcerative Colitis
Conditions
Brief summary
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
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.
