Dietetik

Dietetik, commonly rendered as dietetics in English, is the science and practice of applying nutrition to maintain health, prevent disease, and support treatment and rehabilitation through dietary interventions and food management. It integrates knowledge from biology, physiology, and food science to translate nutrition research into real-world guidance and care.

Professionals in dietetik typically hold accredited degrees in dietetics or nutrition, complete supervised practice, and obtain licensure or registration where required by law. The most widely recognized credential is the registered dietitian (RD) or registered dietitian nutritionist (RDN) in many countries. Practice is guided by evidence-based guidelines, clinical standards, and professional ethical codes, with ongoing professional development emphasized.

Core activities include nutrition assessment, developing individualized nutrition care plans, implementing medical nutrition therapy, and providing counseling and education to individuals and groups. Dietetik professionals may also coordinate with other health care providers, monitor patient progress, and adapt plans as needed. Work settings are diverse and include hospitals and clinics, outpatient programs, public health agencies, schools, elder care facilities, and food service or organization management.

Dietetik intersects with nutrition science, clinical medicine, public health, and food service management. The field has evolved with advances in metabolic understanding, diet-related disease management, and a commitment to evidence-based practice and patient-centered care, reflecting broader trends in health promotion and preventive medicine.
