BACKGROUND/AIMS: To compile a database on content of individual glucosinolates in food and to describe the dietary intake of individual glucosinolates in a German population.
Studies analysing the content of individual glucosinolates in food were aggregated to form a database of 26 individual glucosinolates in 18 vegetables and condiments consumed in Germany. This database was linked to food intake data derived from 24-hour diet recalls of 2,121 participants of the EPIC-Heidelberg cohort study.
Mean total glucosinolate intake (+/-standard error) was 14.2 (+/-1.1) mg/day for men and 14.8 (+/-1.3) mg/day for women. The intake increased with age and education; smokers ingested less glucosinolates than never or former smokers. The quantitatively most important individual glucosinolates were glucobrassicin and sinigrin with mean daily intakes of 3.5 (+/-0.3) and 1.7 (+/-0.2) mg/day for men, and 4.2 (+/-0.4) and 2.5 (+/-0.4) mg/day for women, respectively. Broccoli, Brussels sprouts and cauliflower contributed most to the total glucosinolate intake in this population.
The established database allowed for the first time the estimation of dietary intake of individual glucosinolates. The database can be used for epidemiological research on the role of glucosinolates in health and disease.
背景/目的：编制一份关于食物中单个硫代葡萄糖苷含量的数据库，并描述德国人群中单个硫代葡萄糖苷的膳食摄入量。
汇总分析食物中单个硫代葡萄糖苷含量的研究，形成一个包含德国消费的18种蔬菜和调味品中26种单个硫代葡萄糖苷的数据库。该数据库与来自海德堡欧洲癌症与营养前瞻性研究（EPIC-Heidelberg）队列研究中2121名参与者的24小时饮食回顾得出的食物摄入量数据相关联。
男性中男性硫代葡萄糖苷的平均总摄入量（±标准误）男性为14.2（±1.1）毫克/天，女性为14.8（±1.3）毫克/天。摄入量随年龄和教育程度增加；吸烟者摄入的硫代葡萄糖苷比从不吸烟或曾经吸烟的人少。在数量上最重要的单个硫代葡萄糖苷是萝卜硫素和黑芥子硫苷，男性的平均每日摄入量分别为3.5（±0.3）毫克和1.7（±0.2）毫克，女性分别为4.2（±0.4）毫克和2.5（±0.4）毫克。西兰花、抱子甘蓝和花椰菜对该人群硫代葡萄糖苷的总摄入量贡献最大。
建立的数据库首次实现了对单个硫代葡萄糖苷膳食摄入量的估计。该数据库可用于硫代葡萄糖苷在健康和疾病中的作用的流行病学研究。
