Better outcomes start with personalized nutrition done right.
Personalized nutrition has an entire profession behind it. The ANA trains, certifies, and advocates for the practitioners bringing rigorous, science-based nutrition into mainstream healthcare, one patient, one state, one practice at a time.

// Our stand
“Nutritionist” used to mean almost anything, and nothing at all. We changed that.
The CNS credential exists because personalized nutrition deserves the same rigor as any other clinical discipline: a master’s degree, supervised clinical hours, board examination, and a code of ethics. It’s not a certificate of completion. It’s a profession, with a peer-reviewed journal behind the science and advocates in state capitols behind the scope of practice. And unlike credentialing bodies that protect a smaller circle, the ANA is building a big tent, one where every qualified practitioner can practice to the level of their training.
What makes this a profession
Three things no other organization in personalized nutrition can claim together.

Educational Gaps and Communication Priorities for the Healthfulness of Carbohydrate Foods
Consumers and experts disagreed on how healthy most of 20 common carbohydrate foods are, and experts were often uncertain themselves. White rice, white bread, corn tortillas and fruit juice top the list for clearer patient education.
