NCT04401605

Brief Summary

The purpose of this study is to see how a diet that supplements fermented foods effects inflammation and quality of life in patients with mild to moderate Ulcerative Colitis (UC). There is a paucity of research and an enormous need for better understanding of diet and intestinal inflammation. Fermented food have been shown to positively influence inflammatory cytokines and intestinal microbial diversity in healthy volunteers.
