To assess the intake of glucosinolates and cruciferous vegetables among Spanish adults.
Cross-sectional analysis of a prospective cohort study.
The Spanish cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC).
We analysed data from 40 684 men and women aged 35-64 years from the EPIC-Spain cohort. The usual diet was assessed by means of the dietary history method, and glucosinolate intake was calculated using a published food composition database.
The average intake of cruciferous vegetables was 11.3 g/day, accounting for about 5% of total vegetable consumption, whereas the daily intake of total glucosinolates was 6.5 mg, among which 35% were of indole type. The absolute intake of glucosinolates was in average higher in men than in women (6.8 vs 6.2 mg/day), whereas glucosinolate density per energy unit was higher in women's diet (3.4 vs 2.7 mg/4200 kJ). Northern regions consumed in average 36% more glucosinolates than Southern regions (7.3 vs 5.4 mg/day). There was a positive association of glucosinolate intake with body mass index, physical activity, educational level and an inverse relationship with alcohol consumption.
Contrary to the pattern seen for total vegetable intake, our estimate of consumption of cruciferous vegetables, and hence of glucosinolates, is relatively low within Europe, which in turn is lower than in North America and several Asian populations.
评估西班牙成年人中硫代葡萄糖苷和十字花科蔬菜的摄入量。
一项前瞻性队列研究的横断面分析。
欧洲癌症与营养前瞻性调查（EPIC）的西班牙队列。
我们分析了来自EPIC-西班牙队列中40684名年龄在35至64岁之间的男性和女性的数据。通过饮食史方法评估日常饮食，并使用已发表的食物成分数据库计算硫代葡萄糖苷的摄入量。
十字花科蔬菜的平均摄入量为11.3克/天，约占蔬菜总消费量的5%，而硫代葡萄糖苷的每日总摄入量为6.5毫克，其中35%为吲哚型。男性硫代葡萄糖苷的绝对摄入量平均高于女性（6.8对6.2毫克/天），而女性饮食中每能量单位的硫代葡萄糖苷密度更高（3.4对2.7毫克/4200千焦）。北部地区硫代葡萄糖苷的平均摄入量比南部地区高36%（7.3对5.4毫克/天）。硫代葡萄糖苷摄入量与体重指数、身体活动、教育水平呈正相关，与饮酒量呈负相关。
与总蔬菜摄入量的模式相反，我们对十字花科蔬菜以及硫代葡萄糖苷消费量的估计在欧洲相对较低，而这又低于北美和一些亚洲人群。
