A Registered Dietitian (RD) or Registered Dietitian Nutritionist (RDN) is a food and nutrition expert who provides Medical Nutrition Therapy (MNT) — the treatment of disease through evidence-based nutritional interventions . Unlike nutritionists (often unregulated), dietitians are licensed healthcare professionals who work alongside physicians, nurses, and therapists. This role exists in hospitals (inpatient and outpatient), clinics, private practice, long-term care facilities, sports organizations, corporate wellness, public health programs, research institutions, food industry, and media. Dietitians help manage chronic diseases (diabetes, heart disease, kidney disease, GI disorders), support eating disorder recovery, provide pre/postnatal nutrition, optimize athletic performance, and promote overall health.
