ADA's Nutrition Care Process (NCP) is defined as "a systematic problem-solving method that dietetics practitioners use to critically think and make decisions to address nutrition-related problems and provide safe, effective, high quality nutrition care." The NCP is a standardized process not standardized care. The NCP consists of four distinct but interrelated steps: (1) nutrition assessment, (2) nutrition diagnosis, (3) nutrition intervention, and (4) nutrition monitoring and evaluation. The second step, nutrition diagnosis, is the newest addition to the nutrition care process. The desired format for writing a nutrition diagnosis is a PES (problem, etiology, and signs and symptoms) statement. Nutritional management for diabetes patients is conducted differently by each registered dietitian and medical institution. If a nutritional diagnosis is identified by nutrition assessment in diabetes patients and the accompanying process, which includes implementation of nutrition intervention and monitoring and evaluation of the results of intervention, is standardized, high quality nutritional management through standardized language and documentation is expected to result.
