Dietitian Career Guide

Dietitians assess patients' nutritional needs, develop individualized meal and therapy plans, monitor progress, document outcomes, and counsel patients and families. In clinical settings they collaborate with physicians, nurses and therapists to manage disease-related nutrition (e.g., diabetes, renal disease, cancer), coordinate tube-feeding and parenteral nutrition, perform nutrition screening, lead education groups, and help manage foodservice operations or public health nutrition programs. Daily tasks balance direct patient care, documentation, care planning, interdisciplinary meetings, and continuing education.
