Brief Summary:
Ulcerative colitis is a chronic inflammatory disease primarily involving the colon and has long been considered to be due to a dysregulated immune response targeting the colon, and involves unknown environmental factors. Currently, no effective therapy targets the microbiota or its interaction with the colonic epithelium. Diet has a significant impact on the composition of the microbiota; however, no dietary intervention to date has proven effective for induction of remission. The primary objective of this study is to determine whether the Ulcerative Colitis Diet (UCD) can induce remission or response in pediatric UC patients with active mild to moderate UC on a stable medication.

Arm Intervention/treatment
Experimental: Ulcerative Colitis Diet
Participants will receive a structured 12-week diet with a step down phase.
Other: Ulcerative Colitis Diet (UCD)
The primary study intervention is a novel dietary intervention, the UC Diet. The UC Diet is a structured 12-week diet with a step down phase designed to remove products that allow harmful bacteria to thrive and add products that can change the bacteria in the gut to induce remission

Primary Outcome Measures :
  1. Clinical Remission [ Time Frame: At 6 weeks following enrollment ]
    Remission defined by the Pediatric Ulcerative Colitis Activity Index (PUCAI)

Secondary Outcome Measures :
  1. Dietary Compliance [ Time Frame: Up to 12 weeks following enrollment ]
    Using modified Medication Adherence Rating Scale (MARS) questionnaire

  2. Change in C-reactive protein (CRP) between baseline and week 12 [ Time Frame: 12 weeks ]
  3. Change in erythrocyte sedimentation rate (ESR) between baseline and week 12 [ Time Frame: 12 weeks ]
  4. Change in fecal calprotectin (FCP) between baseline and week 12 [ Time Frame: 12 weeks ]
  5. Microbial composition of the gastrointestinal tract [ Time Frame: 12 weeks ]
    Change in the microbial composition of the stool and rectum from baseline to 12 weeks.
