GLOSSARY

Registered Dietitian (RD) A regulated or credentialed dietetics designation within its relevant jurisdiction; the title's legal meaning should be verified locally.

For example, a sports dietitian and physician can coordinate a nutrition plan when an athlete has unexplained fatigue. Clarify professional roles, credentials and the referral question. Share relevant information with consent so that advice about food, treatment and training is consistent and the athlete is not left to reconcile conflicting instructions.

A nutrition care record should explain the assessment, interpretation, agreed plan, responsible professionals and follow-up criteria. Separate reported information from measured findings and clinical judgments. Record relevant units, dates, methods and changes so that another practitioner can understand the decision. Seek consent for sharing sensitive information and limit access appropriately. A referral should communicate the specific concern and urgency rather than only a broad label. In sport, documentation should support continuity of care while protecting health information from inappropriate use in coaching or selection.

Clinical nutrition translates assessment into an individualized intervention and evaluates the response. A disease name alone cannot define the prescription: disease stage, medication, symptoms, laboratory findings, intake and functional goals matter. Screening identifies possible risk, whereas a full assessment supports a nutrition diagnosis and care plan. A sports context adds training demands but does not remove clinical requirements. Coordinate care when medical and performance objectives interact instead of applying a standard athlete menu to every patient.

A guideline translates evidence into recommendations for a defined population and setting; a consensus statement records an agreed expert interpretation. Neither format removes the need to inspect evidence quality, conflicts of interest, publication date and applicability. A strong-sounding position is not automatically supported by strong trials. Distinguish established practice from a research hypothesis, and revise advice when better evidence emerges. For athletes, explain which part is broadly supported and which is an individualized practical choice rather than presenting every option as mandatory.
