Practice-based Evidence in Nutrition (PEN)pen_logo

There are many areas a dietitian is expected to know about; from diabetes and intolerances to kidney disease and weight management. But, maintaining an accurate overview of the evidence-base in all general and specialised areas of dietetic practice can be a challenge. The PEN system keeps you up-to-date with the fast-paced world of dietetics!

The PEN system condenses and summarises the entire nutrition and dietetic evidence-base on more than 190 nutrition and dietetic-related topics, then gives you practical guidance to help apply to dietetic practice!
