目的评价中国成人每天从蔬菜和水果中摄入的类黄酮,为计算中国成人的膳食类黄酮摄入量提供流行病学基础。方法来自辽宁、北京、江苏和广东的932名16~34的男性参与了本次的横断面研究,时间从2006年4-10月。采用称重法计算来自蔬菜和水果的类黄酮摄入量。结果在年轻男性中每日总类黄酮摄入量为(mg/d)71.55±21.15。杨梅黄酮、槲皮素、坎二菲醇、芹菜配基和玉米黄酮的日平均摄入量(mg/d)分别为(46.43±16.44)、(15.09±4.84)、(4.85±0.79)、(3.23±0.68)和(1.94±0.68)。平均总的类黄醇(杨梅黄酮、槲皮素和坎二菲醇)和黄酮(芹菜培基和玉米黄酮)摄入量(mg/d)分别为66.37±21.55和5.17±1.35。类黄酮最丰富的来源包括蔬菜中的土豆、卷心菜和白萝卜,水果中的苹果和香蕉。辽宁男性每日从蔬菜中摄入的玉米黄酮显著高于江苏和广东,江苏男性每日摄入的玉米黄酮显著低于辽宁和北京。广东男性每日摄入的杨梅黄酮高于辽宁男性。广东男性的槲皮素摄入量显著高于辽宁和江苏,且广东男性从蔬菜中摄入的槲皮素在四个地区中最高。广东男性类黄酮摄入量高于辽宁。结论不同地区间类黄酮摄入量存在显著的不同。杨梅黄酮是类黄酮摄入的主要贡献者。
Objective To evaluate the daily intake of flavonoids from Chinese vegetables and fruits by Chinese adults and provide an epidemiological basis for the calculation of dietary flavonoid intake in Chinese adults. METHODS: A total of 932 men aged 16-34 from Liaoning, Beijing, Jiangsu and Guangdong participated in this cross-sectional study from April to October 2006. Weighed method was used to calculate flavonoid intake from vegetables and fruits. Results The daily total flavonoid intake in young men was (mg / d) 71.55 ± 21.15. The average daily intake of myricetin, quercetin, canndifen, celery ligand and zeaxanthin were (46.43 ± 16.44), (15.09 ± 4.84), (4.85 ± 0.79) and 3.23 ± 0.68) and (1.94 ± 0.68). The average total flavonoids (myricetin, quercetin and mayndanil) and flavones (celery and zeaxanthin) intakes (mg / d) were 66.37 ± 21.55 and 5.17 ± 1.35, respectively. The most abundant sources of flavonoids include potatoes in vegetables, cabbage and turnip, apples and bananas in fruits. Liaoning male daily intake of vegetables from the corn flavonoids was significantly higher than that of Jiangsu and Guangdong, Jiangsu daily intake of maize flavonoids was significantly lower than Liaoning and Beijing. Guangdong men’s daily intake of bayberry flavonoids than Liaoning men. Quercetin intake was significantly higher in Guangdong males than in Liaoning and Jiangsu provinces, and quercetin uptake by vegetables from Guangdong was highest among the four regions. Guangdong male flavonoids intake higher than Liaoning. Conclusions There was a significant difference in flavonoid intake among different regions. Myricetin is a major contributor of flavonoid intake.
