The nutrition care process  is a standardized and systematic approach that nutrition professionals, namely dietitians (referred to as Registered Dietitians, ) and  use to provide care. The NCP has been adopted by international dietetic associations and is updated by an international working group every 5 years .  

 The process follows nutrition screening and consists of four interrelated steps:

 (1) nutrition assessment, 

(2) nutrition diagnosis, 

(3) nutrition intervention and

 (4) nutrition monitoring and evaluation.
