Management of food and nutrition systems (MFNS) encompasses the varied roles of registered dietitian nutritionists (RDNs) with administrative responsibilities for food and nutrition services within an organization. RDNs in MFNS are frequently employed in acute care, but also expand into a multitude of other settings in which management of nutrition and foodservice is required, for example, foodservice departments in assisted living and post-acute and long-term care; colleges and universities, kindergarten through grade 12 and pre-kindergarten schools and childcare; retail foodservice operations; correctional facilities; and companies that produce, distribute, and sell food products. RDNs in MFNS aim to create work environments that support high-quality customer-centered care and services, attract and retain talented staff, and foster an atmosphere of collaboration and innovation.
