GLOSSARY

Nutrition Recommendation A proposed nutrition action whose strength and applicability depend on the evidence, target group and intended outcome.

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.

A nutritional strategy should be evaluated by the quality and relevance of evidence, the athlete's response and the feasibility of implementation. Molecular signaling, a substrate-oxidation change, a laboratory capacity test and race performance are different outcomes. Association does not establish cause, and a response in one small study need not generalize to all athletes. Define the intended benefit before changing the plan, then evaluate training quality, recovery and performance under comparable circumstances rather than judging success by novelty.

Choose a dietary assessment method according to the question, population and resources. A recent intake record can explore meal timing around training; a frequency questionnaire can describe longer-term patterns. Neither automatically establishes exact habitual intake. Combine food details with training, access, symptoms, medication and relevant measurements. Explain uncertainties and what the method cannot answer. Good assessment produces a decision that can be reviewed, rather than an impressive nutrient report whose apparent precision exceeds the quality of the information collected.

For example, a recommendation derived from trained adults may not directly fit a child, pregnant athlete or person with kidney disease. Check the population and outcome before applying it. Explain the uncertainty and adapt practical details without presenting a consensus document as a guarantee of benefit in every individual.

Personalization combines established nutrition principles with the person's training, health, food access, preferences and measured response. Genetics can influence nutrient metabolism, but a commercial gene report rarely determines a complete optimal diet or proves a performance benefit from a specific supplement. Distinguish a reproducible clinical finding from exploratory associations. Nutrigenetics examines variation between people, while nutrigenomics examines interactions between nutrition and genomic function. Use relevant validated information with informed consent and privacy, and avoid replacing ordinary assessment with an attractive but unproven personalized score.

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.

Food practices reflect culture, family, religion, identity and personal preference as well as nutrient composition. Ask what the person actually eats and values rather than assigning a stereotyped pattern. Adapt food examples, preparation methods and meal timing while preserving nutritional adequacy and relevant safety requirements. Cultural restrictions may require suitable replacements, but unfamiliar foods are not inherently inferior. In team travel and clinical care, discuss acceptable options directly so that a well-intended prescription does not leave the person without enough food they can use.
