Individualized nutrition counseling and care is a cornerstone of practice for registered dietitian nutritionists (RDNs). The term personalized nutrition (PN) refers to "individual-specific information founded in evidence-based science to promote dietary behavior change that may result in measurable health benefits." PN technologies, which include the "omics" approaches, may offer the potential to improve specificity of nutrition care through assessment of molecular-level data, such as genes or the microbiome, in order to determine the course for nutrition intervention. These technologies are evolving rapidly, and for many RDNs, it is unclear whether, when, or how these technologies should be incorporated into the nutrition care process. In order to provide guidance in these developing PN fields, International Life Sciences Institute North America convened a multidisciplinary panel to develop guiding principles for PN approaches. The objective of this article is to inform RDN practice decisions related to the implementation of PN technologies by examining the alignment of proposed PN guiding principles with the Code of Ethics for the Nutrition and Dietetics Profession, as well as Scope and Standards of Practice. Guiding principles are described as they apply to each stage of the nutrition care process and include identifying potential beneficiaries, communicating effects transparently, and protecting individual privacy. Guiding principles for PN augment standard guidance for RDNs to pose relevant questions, raise potential concerns, and guide evaluation of supporting evidence for specific PN technologies. RDNs have a responsibility to think critically about the application of PN technologies, including appropriateness and potential effectiveness, for the individual served.

个性化营养技术的进步：注册营养师营养师的指导原则

个性化营养咨询和护理是注册营养师营养师 (RDN) 实践的基石。个性化营养 (PN) 一词是指“以循证科学为基础的个人特定信息，以促进饮食行为的改变，从而可能带来可衡量的健康益处。” PN 技术，包括“组学”方法，可以通过评估分子水平数据（例如基因或微生物组）来确定营养干预的过程，从而提供提高营养保健特异性的潜力。这些技术发展迅速，对于许多 RDN 而言，尚不清楚是否、何时或如何将这些技术纳入营养保健过程。为了在这些发展中的 PN 领域提供指导，北美国际生命科学研究所召集了一个多学科小组来制定 PN 方法的指导原则。本文的目的是通过检查提议的 PN 指导原则与营养和饮食职业道德准则以及实践范围和标准的一致性，为与 PN 技术实施相关的 RDN 实践决策提供信息。指导原则被描述为适用于营养保健过程的每个阶段，包括确定潜在受益者、透明地传达效果和保护个人隐私。PN 的指导原则增强了 RDN 提出相关问题、提出潜在问题并指导评估特定 PN 技术的支持证据的标准指南。
