Best Resources for Evidence-Based Dietary Advice in Medical Conditions

Why RDNs Are the Best Resource

  • RDNs are trained to implement evidence-based dietary interventions based on clinical practice guidelines and current research 4
  • The American Gastroenterological Association specifically recommends referral to RDNs for implementing dietary interventions for conditions like Irritable Bowel Syndrome 1
  • RDNs can provide personalized nutrition care plans based on individual medical conditions, preferences, and needs 4
  • RDNs utilize the nutrition care process to systematically assess, diagnose, intervene, and monitor nutrition-related issues 4, 3
