TL;DR

This perspective paper proposes a novel conceptual framework called Adaptive Personalized Nutrition Advice Systems (APNASs) to extend current personalized nutrition approaches. It argues that such systems should adapt advice to individual needs, capacities, and real-time food environments to improve efficacy and equity.

737 CHARS

The authors present a narrative perspective arguing that current personalized nutrition (PN) approaches, which often use genetic or other individual information, have shown only small to negligible effects on efficacy and effectiveness and may exacerbate health inequalities. They propose a new framework for Adaptive Personalized Nutrition Advice Systems (APNASs). The framework broadens PN goals beyond biomedical targets to include individual preferences, such as sustainable food choices. It emphasizes 'just-in-time' advice delivered in real-life environments via digital ecosystems, accounting for individual capacities and constraints. Finally, it calls for a participatory dialog between individuals and experts for goal-setting.

ABSTRACT

Nearly all approaches to personalized nutrition (PN) use information such as the gene variants of individuals to deliver advice that is more beneficial than a generic “1-size-fits-all” recommendation. Despite great enthusiasm and the increased availability of commercial services, thus far, scientific studies have only revealed small to negligible effects on the efficacy and effectiveness of personalized dietary recommendations, even when using genetic or other individual information. In addition, from a public health perspective, scholars are critical of PN because it primarily targets socially privileged groups rather than the general population, thereby potentially widening health inequality. Therefore, in this perspective, we propose to extend current PN approaches by creating adaptive personalized nutrition advice systems (APNASs) that are tailored to the type and timing of personalized advice for individual needs, capacities, and receptivity in real-life food environments. These systems encompass a broadening of current PN goals (i.e., what should be achieved) to incorporate “individual goal preferences” beyond currently advocated biomedical targets (e.g., making sustainable food choices). Moreover, they cover the “personalization processes of behavior change” by providing in situ, “just-in-time” information in real-life environments (how and when to change), which accounts for individual capacities and constraints (e.g., economic resources). Finally, they are concerned with a “participatory dialog between individuals and experts” (e.g., actual or virtual dieticians, nutritionists, and advisors) when setting goals and deriving measures of adaption. Within this framework, emerging digital nutrition ecosystems enable continuous, real-time monitoring, advice, and support in food environments from exposure to consumption. We present this vision of a novel PN framework along with scenarios and arguments that describe its potential to efficiently address individual and population needs and target groups that would benefit most from its implementation.
