: The EAT-Lancet Commission proposed a healthy and sustainable 'planetary health diet' (PHD) based on the nutritional needs of adults, but recommended for all population groups over the age of two years. This study investigated the extent to which UK adolescent diets meet these recommendations, and the association between meeting recommendations and nutritional intake. : Dietary intake data collected from students aged 11-15 years between 2019 and 2022 as part of the Food provision, cUlture and Environment in secondary schooLs (FUEL) study was used. Specifically, 24 h intakes of food groups and key nutrients were summarised for each participant, and micronutrient intake was expressed as a percentage of the reference nutrient intake (RNI). The proportion of participants meeting each PHD recommendation was calculated. A PHD index score was developed to measure the overall adherence to recommendations. Multilevel linear regression models were fitted to explore the association between the PHD score and intake of each nutrient. : No participants fully met the recommendations. The mean PHD score was 14.2 (3.3) out of 39. Adherence was low for the emphasised foods, and lowest for nuts (1.3%) and unsaturated oils (0.2%). Higher PHD index scores were associated with lower intakes of all micronutrients, with the largest association for vitamin B12 [regression coefficient: -12.9% (95% CI: -16.3, -9.4) of RNI] and the smallest for vitamin D [regression coefficient: -0.4 (95% CI: -0.7, -0.2) of RNI]. : Substantial dietary changes are needed for this population group to meet the PHD guidelines. Further research should focus on why these recommendations may lead to the inadequate intake of some nutrients in this age group. We propose that the PHD guidance needs to be reviewed and potentially adapted for this specific population, with consideration of the typical dietary behaviours of this age group.
柳叶刀委员会（EAT-Lancet Commission）基于成年人的营养需求提出了一种健康且可持续的“行星健康饮食”（PHD），但建议适用于所有两岁以上的人群。本研究调查了英国青少年饮食符合这些建议的程度，以及符合建议与营养摄入之间的关联。：使用了2019年至2022年期间作为中学食品供应、文化与环境（FUEL）研究的一部分从11至15岁学生收集的饮食摄入数据。具体而言，汇总了每位参与者24小时的食物组和关键营养素摄入量，微量营养素摄入量以参考营养素摄入量（RNI）的百分比表示。计算了符合每项PHD建议的参与者比例。制定了一个PHD指数得分来衡量对建议的总体遵守情况。采用多水平线性回归模型来探讨PHD得分与每种营养素摄入量之间的关联。：没有参与者完全符合建议。PHD平均得分在满分39分中为14.2（3.3）。对于重点强调的食物，遵守率较低，坚果（1.3%）和不饱和油（0.2%）的遵守率最低。较高的PHD指数得分与所有微量营养素摄入量较低相关，其中与维生素B12的关联最大[回归系数：RNI的 -12.9%（95%置信区间：-16.3，-9.4）]，与维生素D的关联最小[回归系数：RNI的 -0.4（95%置信区间：-0.7，-0.2）]。：该人群组需要进行重大饮食改变才能符合PHD指南。进一步的研究应关注这些建议为何可能导致该年龄组某些营养素摄入不足。我们建议需要对PHD指南进行审查，并可能针对这一特定人群进行调整，同时考虑该年龄组的典型饮食行为。
