Study Arms:
- carrageenan-free diet with placebo (Type: EXPERIMENTAL): This is the experimental arm in which subjects will be on a no-carrageenan diet and receive placebo capsules. This will test whether the no carrageenan diet leads to longer relapse-free interval for patients with ulcerative colitis.
- carrageenan-free diet w/ carrageenan (Type: ACTIVE_COMPARATOR): The carrageenan-free diet with carrageenan supplement will mimic the carrageenan normally consumed in the diet. The study will permit blinded comparison of carrageenan-free vs. carrageenan consumption.

Based on this trial design, predict the completion outcome and termination type (if applicable).
