CNH8 Provide Nutritional Therapy to clients

Overview

This standard is about providing Nutritional Therapy to clients.  Nutritional Therapy Practitioners work in preventive medicine, the optimization of physical and mental health, and in the treatment of chronic diseases, often with complex multiple causes.  Nutritional Therapy encompasses personalized dietary therapy and nutraceutical prescription, and life style advice within a functional medicine framework.

The scope of practice for Nutritional Therapy excludes artificial (parenteral/enteral) feeding and dietary management of acute life threatening states, e.g. intestinal or renal failure, and injury trauma.

Users of this standard will need to ensure that practice reflects up to date information and policies.

Knowledge and Understanding

You will need to know and understand:

  1. the historical development of the therapy and the profession
  2. the concepts underpinning functional systems biology/medicine, and patient centred approaches
  3. the concept of Nutritional Therapy as a process driven modality
  4. the concepts underpinning CAM, and integrative and orthodox medicine
  5. roles that evidence-based and traditional research play in informing clinical decision-making
  6. how to use questionnaires and diaries to optimise gathering of information
  7. methods for obtaining and recording anthropometric measurements
  8. methods for conducting and recording observations of health status
  9. how to select, when appropriate, biochemical, nutritional and functional tests
  10. how to use support materials, resources and information to increase compliance
  11. how to communicate with other health professionals to provide a client-centred integrated approach
  12. how to use the client’s story as a key tool for integrating diagnosis, signs and symptoms, and evidence of clinical imbalances into a comprehensive approach to improve both the patient’s environmental inputs and physiological function
  13. how to apply a functional systems biology/medicine, and patient centred approach
  14. how to use prognosis to rationalize strategies for prioritisation, and timeline planning
  15. how to identify situations in which it may be appropriate to delay implementing all or part of a treatment plan
  16. ways in which individual safety may be compromised by inappropriate treatment and how to minimise such risks
  17. how to interpret and evaluate data from observations and laboratory tests

  19. how to synthesize new information and modify the treatment plan over successive consultations
  20. issues in translating government guidelines, epidemiological, and other research findings to the construction of individualized interventions
  21. models of reflection and how these are applied to practice
  22. strategies for managing potential dissonance between expected and actual treatment outcomes for self and client
  23. the relationship the client has with food, food groups and dietary models
  24. how different cultures describe effects of food on health
  25. how to conduct quantitative and qualitative analyses of food intake

  31. the approach of orthodox dietetics in prevention and treatment, including enteral and parenteral nutrition, to facilitate collaboration and identify professional boundaries
  32. the nature and extent of changes to performance or symptoms expected
  33. how to distinguish perceived negative effects that may be experienced by individuals from other causes of change
  34. how changes are explained by nutritional therapy principles

  51. the functioning and web-like interaction between tissues and organs at the, cellular and systemic levels
  52. the core clinical imbalances that underlie various disease conditions
  53. the clinical signs and symptoms generated by the body’s response to stress, poor nutrition, insult or injury through exposure to endogenous and exogenous toxins, allergens, infectious agents, parasites, other environmental factors, genetic predisposition, emotional and psychosocial factors
  54. common biomedical terminology used in pathology
  55. the aetiology and pathology of common diseases and their clinical features
  56. the impact of microbiota on health
  57. how to ascertain the sensitivity, specificity and validity of diagnostic tests
  58. selection, use and evaluation of tests of biochemistry, pathology, microbiology genetic information, and functionality in diagnosis and monitoring
  59. differential diagnoses of common conditions and diseases
