Brief Summary:
This protocol is designed to compare the effectiveness of two dietary interventions for patients with Crohn's disease (CD): the Specific Carbohydrate Diet (SCD) and a Mediterranean style diet (MSD) that has been demonstrated to have numerous other health benefits. The two diets will be compared in terms of their ability to resolve both the symptoms and bowel inflammation that characterize this debilitating disease.

  2. Reduction in bowel inflammation [ Time Frame: 6 weeks ]
    Calprotectin <250 mcg/gm and >50% reduction from baseline

Secondary Outcome Measures :
  1. Clinical remission [ Time Frame: 6 weeks ]
    Assessed by the Harvey Bradshaw Index

  2. Reduction in systemic inflammation [ Time Frame: 6 weeks ]
    hsCRP < 5mg/L >50% reduction from baseline

    • Patients may continue these medications at stable dose for the first six weeks and budesonide may be used at any dose. After the 6th week in the study, patients may taper their steroid dose. The study will provide a recommended taper schedule.

      • Loading/induction doses of biologic type medication will be considered a stable doses. ***Exception for treatment failures: if a subject is determined to fail on any of the following standard lines of treatment at the treating investigator's discretion, subjects may screen for study intervention based upon the following wash out periods: 4 weeks for thiopurine and methotrexate and 8 weeks for natalizumab, vedolizumab, anti-TNF, or ustekinumab.
