The second tier of nutrition services is the provision of nutrition therapy, which includes individualized assessment of nutritional status, evaluation of nutritional needs, and intervention, which ranges from counseling on diet prescriptions to the provision of enteral and parenteral nutrition.

Nutrition therapy encompasses the assessment of an individual’s nutritional status, evaluation of nutritional needs, and interventions or counseling to achieve optimal clinical outcomes. The assessment of nutritional needs takes into consideration the individual’s medical and dietary histories, as well as physical, anthropometric, and laboratory data. Nutrition therapy includes oral, enteral, and parenteral nutrition interventions and takes into consideration the cultural, socioeconomic, and food preferences of the individual.
