Abstract

Background

Despite growing evidence that personalized nutrition (PN) can improve dietary behavior and health outcomes, the implementation of PN food services in real-world settings remains largely unexplored.

Objectives

This study evaluated the feasibility of a PN service to deliver personalized nutrition products (PNPs) in a military setting and assessed consumer acceptance following repeated consumption.

Methods

A PN service was developed to design, produce, and distribute PNPs. Twenty-five participants from the Royal Netherlands Army took part in a feasibility study, using a single-cohort pretest posttest design. Each participant consumed a PNP (in-between meal) on 10 consecutive days during a combat training exercise. Product liking was assessed through daily questionnaires, whereas broader user experiences were assessed at baseline (t = 0), 1-wk follow-up (t = 1), and 2-wk endline (t = 2).

Results

The PN service was successfully implemented during a military training exercise. In total, 229 PNPs were produced and distributed. Participants evaluated all aspects of the PN service as slightly positive (4.5 ± 1.4 to 5.0 ± 1.7 on 7-point scales), except for variation in products, which was rated as slightly negative (3.4 ± 1.6). Across the different product combinations, mean overall liking and all sensory attributes were slightly positive (5.7 ± 1.7 to 6.1 ± 1.6 on 9-point scales). Overall product liking did not change over time (F (9, 194) = 1.242, P = 0.27). Attitudes toward a PNP service in the army were positive at study start but decreased to neutral at study end.

Conclusions

This study supports the feasibility of a prototype PN service in a real-life military setting. The PNPs received modestly positive evaluations, and repeated exposure did not change the overall liking of the products. Initial positive attitudes toward the service declined over time. Therefore, further optimization of both the service and the PNPs is needed before implementation at a larger scale can be considered.

在真实的军事环境中实施个性化营养服务：可行性和消费者接受度

尽管越来越多的证据表明个性化营养（PN）可以改善饮食行为和健康结果，但在现实环境中实施PN食品服务在很大程度上仍未得到探索。尽管越来越多的证据表明个性化营养（PN）可以改善饮食行为和健康结果，但在现实环境中实施PN食品服务在很大程度上仍未得到探索。本研究评估了PN服务在军事环境中提供个性化营养产品（PNPs）的可行性，并评估了重复消费后消费者的接受程度。本研究评估了在军事环境中提供个性化营养产品（PNPs）的PN服务的可行性，并评估了重复消费后消费者的接受程度。方法建立pnp服务系统，设计、生产、销售pnp。来自荷兰皇家陆军的25名参与者参加了一项可行性研究，采用单队列前测后测设计。在连续10天的战斗训练中，每个参与者都吃了一顿PNP（中间餐）。产品喜欢度通过日常问卷进行评估，而更广泛的用户体验则在基线（t = 0）、1周随访（t = 1）和2周终点（t = 2）进行评估。开发了一个PN服务来设计、生产和分发pnp。来自荷兰皇家陆军的25名参与者参加了一项可行性研究，采用单队列前测后测设计。在连续10天的战斗训练中，每个参与者都吃了一顿PNP（中间餐）。产品喜欢度通过日常问卷进行评估，而更广泛的用户体验则在基线（t = 0）、1周随访（t = 1）和2周终点（t = 2）进行评估。结果在一次军事演习中成功实施了PN服务。共编制和分发了229份国家行动纲领。参与者对PN服务的所有方面都进行了略正面的评价（在7分制中为4.5±1.4至5.0±1.7），除了产品的变化，被评为略负面（3.4±1.6）。在不同的产品组合中，平均总体喜欢度和所有感官属性略为正（在9分制中为5.7±1.7至6.1±1.6）。整体产品喜欢度没有随时间变化（F (9,194) = 1.242, P = 0.27）。在研究开始时，对军队中PNP服务的态度是积极的，但在研究结束时，态度下降到中性。PN服务在一次军事训练演习中成功实施。共编制和分发了229份国家行动纲领。参与者对PN服务的所有方面都进行了略正面的评价（在7分制中为4.5±1.4至5.0±1.7），除了产品的变化，被评为略负面（3.4±1.6）。在不同的产品组合中，平均总体喜欢度和所有感官属性略为正（在9分制中为5.7±1.7至6.1±1.6）。整体产品喜欢度没有随时间变化（F (9,194) = 1.242, P = 0.27）。在研究开始时，对军队中PNP服务的态度是积极的，但在研究结束时，态度下降到中性。本研究支持了在现实军事环境中原型PN服务的可行性。PNPs获得了适度的正面评价，反复接触并没有改变产品的总体喜好。最初对这项服务的积极态度随着时间的推移而下降。因此，在考虑大规模实现之前，需要对服务和pnp进行进一步优化。这项研究支持了原型PN服务在现实军事环境中的可行性。PNPs获得了适度的正面评价，反复接触并没有改变产品的总体喜好。最初对这项服务的积极态度随着时间的推移而下降。因此，在考虑大规模实现之前，需要对服务和pnp进行进一步优化。
