Learn more about PEN: Practice-based Evidence in Nutrition®

Practice-based Evidence in Nutrition (PEN) is a global, dynamic knowledge translation tool that allows busy practitioners to quickly find up-to-date answers to day-to-day questions, based on the latest evidence. It was developed by Dietitians of Canada, with input from thought leaders and practitioners in dietetic practice and is managed by a collaborative partnership between the British Dietetic Association, Dietitians Australia and Dietitians of Canada.

The PEN System is designed as a series of over 200 knowledge pathways (similar to chapters in a book) that includes practice questions, background information, recommendations and evidence summaries, practice guidance toolkits and links to relevant tools and resources, including client handouts, on hundreds of topics. 

DC membership includes access to the PEN system in the form of 50 access credits (logins). Find out about this member benefit and more

What are the benefits of using the PEN System?

  • Saves you time searching and appraising because the PEN Team finds and analyzes the best available evidence and then summarizes the key information on a particular topic.  
  • Access to diverse dietetic topics ranging from population health, the lifecycle, health conditions and disease, food and nutrients and professional practice. All this information is frequently reviewed and updated, and new content is continually being added.
  • All of the evidence is graded, using the prestigious GRADE approach, so you always know the quality of the evidence behind a nutrition or dietetic recommendation. 
  • Access to cited references; all linked to the abstract or full text so you can easily locate the original journal article or research paper.
  • Useful features such as multilingual navigation, filtered results, personalization of your favourites, and content alerts for new and revised content.
