槲皮素和相关的类黄酮在大鼠中具有抗癌作用，但对人类的摄入量知之甚少。研究人员利用来自14个国家的17名志愿者的1天饮食记录，以及8名荷兰成年人的3天饮食记录和食物频率问卷，计算了5种主要黄酮醇和黄酮的摄入量。根据3天记录，国际受试者的总摄入量（+/- sd）为27.6 +/- 19.5 mg/天，荷兰成年人为34.1 +/- 31.2 mg/天，调查问卷显示为41.9 +/- 23.7 mg/天。槲皮素占68-73%，山奈酚占22-29%，主要来源于茶叶和洋葱。一个简短的食物频率问卷可能是根据黄酮醇摄入量对个体进行排名的合适方法。(C) 1997爱思唯尔科学爱尔兰有限公司
Quercetin and related flavonoids are anticarcinogenic in rats, but little is known about human intakes. The intake of five major flavonols and flavones was calculated using 1-day dietary records of 17 volunteers from 14 countries, and using both 3-day records and a food frequency questionnaire of eight Dutch adults. Total consumption (+/-SD) was 27.6 +/- 19.5 mg/day in the international subjects, 34.1 +/- 31.2 mg/day in the Dutch adults according to 3-day records, and 41.9 +/- 23.7 mg/day according to questionnaires. Quercetin contributed 68-73%, and kaempferol 22-29%, the major sources being tea and onions. A brief food frequency questionnaire may be a suitable method for ranking individuals by flavonol intake.
