黄酮类和异黄酮类的摄入量是根据40种食物的初步数据库估计的，这些食物至少占总食物消费量的80%。1996年9月，“i-City”的50名志愿妇女记录了3天内所有膳食摄入量的重量，并接受了健康检查和实验室检查。根据各种食物因素对数据进行了分析。平均每人每天摄入的黄酮类如下：山奈酚4.9 mg、槲皮素8.3 mg、芦丁1.5 mg、杨梅素0.6 mg、木犀草素0.3 mg、杨梅苷0.01 mg、菲斯汀0.4 mg、芥子醇0.3 mg。蔬菜和水果的总摄入量均在10 mg以下，每天摄入大豆苷元和染料木素等异黄酮类成分分别为16.2 mg(3.18~35.61 mg)和23.27 mg(4.62~52.12 mg)，总摄入量为39.46 mg(7.80~87.73 mg)。对进食的维生素、黄酮类和异黄酮类进行了主成分分析。因子1主要由类黄酮类和抗氧化维生素组成。因子1与年龄、高密度脂蛋白水平呈正相关，与甘油三酯水平呈负相关。因子2主要由异黄酮类化合物组成，与肌酐和尿酸水平呈正相关。到目前为止，这些因素与骨密度和其他健康指数，如BMI和血压还没有显示出显著的关联。
The intake of flavonoids and isoflavonoids was estimated based upon a preliminary database of 40 food items, covering at least 80% of total food consumption. Fifty volunteer women in "I-City" recorded the weight of all dietary intake for 3 days in September 1996, and received a health check-up, as well as laboratory examination. The data was analyzed in relation to the various food factors. Average daily intake per capita of flavonoids was as follows: 4.9 mg kaempferol, 8.3 mg quercetin, 1.5 mg rutin, 0.6 mg myricetin, 0.3 mg luteolin, 0.01 mg myricitrin, 0.4 mg fisetin, and 0.3 mg eriodictyol. Total intake from vegetables and fruits was less than 10 mg 16.2 mg (range: 3.18-35.61 mg) and 23.27 mg (4.62-52.12 mg) of isoflavones, such as daidzein and genistein, respectively, were taken per day, and total isoflavone intake was 39.46 mg (7.80-87.73 mg). Chief component analysis on ingested vitamins, flavonoids and isoflavonoids was carried out. Factor 1 was mainly composed of flavonoids and antioxidant vitamins. Factor 1 was positively associated with age and the level of HDL cholesterol and negatively related to the level of triglycerides. Factor 2, which was mainly composed of isoflavonoids, was positively associated with creatinine and uric acid levels. So far, these factors did not show a significant association with bone density and other health indices, such as BMI and blood pressure.
