Les valeurs nutritionnelles de référence (VNR) constituent un outil essentiel dans les domaines de la nutrition clinique et de la santé publique. Elles fournissent des repères permettant d’évaluer les apports nutritionnels, tant au niveau individuel que populationnel, afin d’identifier les situations adéquates ainsi que celles à risque de carence ou d’excès, et d’orienter les interventions nutritionnelles. De nouvelles VNR sont disponibles pour la Suisse depuis 2022 et constituent désormais la référence nationale. Cet article présente les principes qui sous-tendent les VNR et illustre leur utilisation concrète en pratique clinique et en santé publique. Des exemples d’application sont présentés à travers l’évaluation des apports alimentaires en se focalisant sur trois nutriments et dans le cadre de l’élaboration de recommandations nutritionnelles.
Nutritional reference values (NRV) are an essential tool in clinical nutrition and public health. They provide benchmarks for assessing dietary intake at the individual and population levels, to identify situations at risk of deficiency or excess and to guide nutritional interventions. New NRV have been available for Switzerland since 2022 and now constitute the national reference. This article presents the principles underlying NRV and illustrates their practical application in clinical practice and public health. Examples of applications are provided, particularly in relation with the assessment of dietary intake, focusing on three nutrients, and the development of nutritional recommendations.
