This study analyzed the correlations between the acute and habitual intake of dietary tyrosols, their main food sources, and 24 h urine excretions of tyrosol (Tyr) and hydroxytyrosol (OHTyr) in participants from the European Prospective Investigation into Cancer and Nutrition study (EPIC). Participants (n = 419) were healthy men and women aged from 34 to 73 years from 8 EPIC centers belonging to France, Italy, and Germany. Acute and habitual dietary data were collected using a standardized 24 h dietary recall software and validated country-specific dietary questionnaires, respectively. The intake of 13 dietary tyrosols was estimated using the Phenol-Explorer database. Excretions of Tyr and OHTyr in a single 24 h urine sample were analyzed using tandem mass spectrometry. Urinary excretions of Tyr, OHTyr, and their sum (Tyr + OHTyr) correlated more strongly with their corresponding acute (rho0.63) rather than habitual intakes (rho0.47). In addition, individual and combined urinary excretions of Tyr and OHTyr were weakly to moderately correlated with the acute and habitual intake of other individual tyrosol precursors (rho = 0.10-0.44) and especially with major food sources, such as wine (rho = 0.41-0.58), olive oil (rho = 0.25-0.44), and beer (rho = 0.14-0.23). Urinary Tyr + OHTyr excretions were similarly correlated with the acute intake of total tyrosols but differently correlated with food sources among countries. Based on these results, we conclude that 24 h urinary excretions of Tyr + OHTyr could be proposed as biomarkers of total tyrosol intake, preferably for acute intakes.
本研究分析了欧洲癌症与营养前瞻性调查研究(EPIC)参与者中膳食酪醇的急性和习惯性摄入量、其主要食物来源与酪醇(Tyr)和羟基酪醇(OHTyr)24小时尿排泄量之间的相关性。参与者(n = 419)为来自法国、意大利和德国8个EPIC中心的34至73岁健康男性和女性。急性和习惯性饮食数据分别使用标准化的24小时饮食回忆软件和经过验证的特定国家饮食问卷收集。使用酚类物质探索者数据库估计13种膳食酪醇的摄入量。使用串联质谱法分析单次24小时尿液样本中Tyr和OHTyr的排泄量。Tyr、OHTyr及其总和(Tyr + OHTyr)的尿排泄量与其相应的急性摄入量(rho0.63)的相关性比习惯性摄入量(rho0.47)更强。此外,Tyr和OHTyr的个体及联合尿排泄量与其他单个酪醇前体的急性和习惯性摄入量(rho = 0.10 - 0.44),特别是与主要食物来源,如葡萄酒(rho = 0.41 - 0.58)、橄榄油(rho = 0.25 - 0.44)和啤酒(rho = 0.14 - 0.23)之间的相关性较弱至中等。尿中Tyr + OHTyr排泄量与总酪醇的急性摄入量的相关性相似,但在不同国家与食物来源的相关性不同。基于这些结果,我们得出结论,Tyr + OHTyr的24小时尿排泄量可被提议作为总酪醇摄入量的生物标志物,急性摄入量时更佳。
