Nutritionist Terminology Guide

Key terms every nutritionist should know — drawn from the ABCN Certified Nutritionist curriculum. Search or filter by topic.

This glossary is general nutrition education from the American Board of Certified Nutritionists (ABCN). It is not medical advice. The Certified Nutritionist (CN) credential is a private certificate — not a Registered Dietitian Nutritionist (RDN) credential and not a state license.
