Practice-based Evidence in Nutrition (PEN)TM

Global resource library

The PEN system is a global library of evidence-based resources developed by Dietitians of Canada, with Dietitians Australia and the British Dietetic Association as global partners. It's a powerful database where you'll find answers to your dietetic questions.

Use the PEN system to find:

  • practice guidance toolkits
  • calculators and tools
  • client handouts
  • emerging evidence
  • evidence summaries
  • international guidelines
  • nutrition research
  • trending topics

PEN helps busy dietitians keep up to date with credible evidence to use in their practice.
