The present study aimed to assess the correlation between food and fatty acid (FA) intake and the serum phospholipid (PL) FA status in European adolescents and explored the percentage of variation in serum PL FA that could be attributed to dietary habits. Participants included 528 adolescents recruited in the HELENA Study. Dietary intake was assessed by two, self-administered, non-consecutive 24-h recalls. PL FA concentrations were measured in fasting venous serum samples. Reduced rank regressions were applied to examine the combined effect of food intakes. Results indicated that the variance in serum PL FA in adolescents, that could be explained by diet varied from 7.0% for MUFA to 14.2% for n-3FA. The variance in the long-chain n-3FA was mainly explained by fish intake but also by coffee and tea consumption. In conclusion this study indicated that dietary intake influences the serum PL FA status to a limited amount but that also other factors interfere. However, dietary intake is important as it is among those factors that could be modified. Furthermore, the results suggest that the overall dietary habits should be considered instead of only the consumption of single foods or nutrients, as the medium of the food or concomitant intake of foods and nutrients might interact and as such influence absorption or metabolism.
本研究旨在评估欧洲青少年食物和脂肪酸（FA）摄入量与血清磷脂（PL）FA状态之间的相关性，并探讨血清PL FA中可归因于饮食习惯的变异百分比。参与者包括在HELENA研究中招募的528名青少年。通过两次非连续的24小时自我管理回忆来评估饮食摄入量。在空腹静脉血清样本中测量PL FA浓度。应用降秩回归来检验食物摄入量的综合影响。结果表明，青少年血清PL FA中可由饮食解释的变异，从单不饱和脂肪酸（MUFA）的7.0%到n-3脂肪酸（n-3FA）的14.2%不等。长链n-3FA的变异主要由鱼类摄入量解释，但也与咖啡和茶的消费有关。总之，本研究表明饮食摄入量对血清PL FA状态的影响有限，但也有其他因素起作用。然而，饮食摄入量很重要，因为它是可以改变的因素之一。此外，结果表明应考虑整体饮食习惯，而不仅仅是单一食物或营养素的消费，因为食物的介质或食物与营养素的同时摄入可能相互作用，从而影响吸收或代谢。
