ABSTRACT
INTRODUCTION: Diet has vital, preventive and therapeutic functions. Medical nutrition therapy is a part of the Standardized Nutrition Care Process integrated in health care systems. MATERIAL AND METHODS: An overview of the Nutrition Care Process model and the application of nutrition guidelines based on literature, reports, documents and programmes of international health, food and physical activity authorities was done. RESULTS: The Nutrition Care Process model requires registered dieticians, standardized terminology as well as nutrition diagnosis categorization. It consists of four distinct, but interrelated and connected steps: (a) nutrition assessment, (b) nutrition diagnosis, (c) nutrition intervention, and (d) nutrition monitoring and evaluation. An individual approach is essential for successful medical nutrition therapy. Nutrition guidelines facilitate the process of understanding and application of medical nutrition therapy. CONCLUSION: The Nutrition Care process provides dietetic professionals information on high-quality client nutrition care. The success of medical nutrition therapy rests not only upon the advice of the dietician, but also upon the client's compliance.
