Low Animal Protein(LAP) modified Specific Carbohydrate Diet in Pediatric Ulcerative Colitis

For this study, the investigators will examine the effect of low animal protein diet modified SCD in active ulcerative colitis. The investigators are examining how well a LAP SCD is tolerated and whether the LAP SCD appears effective for the treatment of active UC. Patients will be evaluated at 2, 4, 8, and 12 weeks with CBC, sedimentation rate, C-reactive protein, albumin, and stool for microbiome analysis at each follow up visit.
