Flavonoids have been hypothesized to reduce the risk of chronic diseases, but lack of flavonoid database hampered epidemiologic studies addressing this issue in Korea. The objectives of this study were to construct a Korean flavonoid database and to estimate daily flavonoid intake among Korean adults. For Korean foods with flavonoid analytic data, only the data satisfied with a certain quality by USDA nutrient data evaluation system were added in database. The USDA flavonoid database was mainly used as the flavonoid data source and the Japan Functional Food Composition Database was also used. Flavonoid contents for combination foods were calculated using the standard recipes. Dietary flavonoid intakes for adults aged +19yr were estimated based on 24‐h dietary recall (DR) of the Korean NHANES 2008. The developed flavonoid database included 100% of fruits and fruit juices, 83% of vegetables, 100% of legumes and legume products, and, overall 85% of all plant foods (945 items) reported by 24‐h DR of the Korean NHANES 2008. Mean daily flavonoid intakes were 17.7 mg, 29.2 mg, 6.7 mg, 0.97 mg, 29.4 mg, and 27.1 mg for anthocyanidins, flavan‐3‐ols, flavonones, flavones, flavonols, and total isoflavones, respectively. The top contributing foods for anthocyanidins, flavan‐3‐ols, flavonones, flavones, flavonols, and total isoflavones were radishes, green tea, tangerines, Baechu‐kimchi, onions and soybeans. These data can be used in studies investigating the relation between flavonoid intake and several diseases. Grant Funding Source : Nutrition(ASN)
