  • Sites of digestion and of absorption of macronutrients and micronutrients
  • How GI dysfunction, surgical resections, disease, and gut microbiota affect nutrition and health
  • Knowledge of evidence-based pathways of care for patients with GI disorders based on disease and treatment type including recognition of appropriate time points for nutrition screening, assessment, intervention and monitoring
  • Value and limitations of enteral and parenteral formulas, evidence-based therapeutic diets, probiotics, common nutraceuticals and other common adjacent therapies

  • Can explain the relative strength of association between therapeutic diets used to manage or treat GI disorders and outcomes expected
  • Predict nutritional inadequacies, intolerances, or complications resulting from dietary inadequacies, GI disease and/or resections
  • Estimation of nutritional requirements (energy, macronutrients, micronutrients, fibre and fluid) relevant for specific GI disorders accounting for variations that occur due to fluctuations in condition stability, medical therapy outcomes and gastrointestinal losses.
  • Ability to provide evidence based, specific and tailored advice to the individual with the GI disorder, considering the changing physiological and psychosocial needs related to disease state and treatment (pharmaceutical, surgical, psychotherapy, dietary, biological therapies).

Activities entry level APDs would conduct

Activities APDs working at a higher level would conduct
