  • Intervention
    In adults with gastrointestinal disorders (i.e., inflammatory bowel syndrome/disease, Crohn’s disease, ulcerative colitis), what is the cost benefit of MNT provided by a Registered Dietitian Nutritionist (RDN)?
    • Conclusion

      No published research studies were found on this topic. Future research assessing the cost effectiveness of MNT provided by a nutrition professional (registered dietitian nutritionist or equivalent) to improve gastrointestinal disorder outcomes is imperative.

    • Grade: V
      • Grade I means there is Good/Strong evidence supporting the statement;
      • Grade II is Fair;
      • Grade III is Limited/Weak;
      • Grade IV is Expert Opinion Only;
      • Grade V is Not Assignable.
      • High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
      • Moderate (B) means we are moderately confident in the effect estimate;
      • Low (C) means our confidence in the effect estimate is limited;
      • Very Low (D) means we have very little confidence in the effect estimate.
      • Ungraded means a grade is not assignable.
    In adults with gastrointestinal disorders (i.e., celiac disease, inflammatory bowel syndrome/disease, Crohn’s disease, ulcerative colitis), what is the effectiveness of MNT provided by a Registered Dietitian Nutritionist (RDN) on health outcomes (i.e., weight status, GI distress, nutrient deficiencies)?
    • Conclusion

      Evidence suggests that patients with celiac disease who received MNT by a nutrition professional (registered dietitian nutritionist or equivalent) had increased adherence to the GF diet, reduced gastrointestinal distress, improved intestinal villous atrophy and improved BMI, although the extent of positive outcomes varied among the studies. Additional research is required. No conclusions could be drawn about the optimal frequency, duration of nutrition professional (RDN or equivalent) visits or MNT effectiveness for other gastrointestinal disorders.
