我们估计的摄入量的个别黄酮类化合物的横断面研究，并澄清了主要来源的黄酮类化合物水平的中年日本妇女的24小时称重饮食记录研究。研究对象包括516名自由生活的妇女。每名受试者完成24小时称重饮食记录并接受健康检查。我们使用功能性食物因素数据库来估计5种主要黄酮类化合物的摄入量，即黄烷-3-醇、黄酮、黄酮醇、黄烷酮和黄酮。黄烷-3-醇、异黄酮、黄酮醇、黄烷酮和黄酮的平均摄入量分别为1277、216、58、31和15 μ mol/d。黄烷-3-醇最丰富的来源是绿色茶。大豆加工食品是黄嘌呤的3个主要食物来源，洋葱、黄萝卜叶和日本萝卜叶是黄嘌呤的3个主要食物来源。葡萄柚和柑橘类果汁是黄酮类化合物的主要来源，而鹤村崎（马拉巴菠菜）、绿色辣椒和葡萄柚是黄酮类化合物的主要来源。此外，对日本中年妇女亚样本的分析表明，类黄酮摄入量与氧化LDL水平之间可能存在关联，这可能与心血管疾病的发病率有关。
We estimated the intake of individual flavonoids in a cross sectional study and clarified the major sources contributing to the flavonoid levels in the middle-aged Japanese women by a 24-h weighed dietary record study. The subjects included in the study were 516 free-living women. Each subject completed a 24-h weighed dietary record and received a health check-up. We used the Functional Food Factor database for estimating the intake of 5 major flavonoid intakes, i.e. flavan-3-ols, isoflavones, flavonols, flavanones and flavones. The mean intake of flavan-3-ols, isoflavones, flavonols, flavanones and flavones was 1277, 216, 58, 31 and 15 mu mol/d, respectively. The richest source of flavan-3-ols was green tea. The 3 major food sources of isoflavone were the processed soy foods and those of flavonol were the onion, moroheiya (nalta jute) and Japanese radish leaves. Grapefruit and citrus fruit juices were the major sources of flavanones, and tsurumurasaki (malabar spinach), green pepper and grapefruit were the main sources of flavone. Furthermore, analysis of sub-samples from middle-aged Japanese women indicated that there may be an association between flavonoid intake and the levels of oxidized LDL, which might be related to the incidence of cardiovascular diseases.
