Abstract:
Knowing the dietary flavonoid intake of individuals and populations is the first step to clearly understand their health effects. Dietary flavonoid intake studies have been hampered by the lack of flavonoid food composition data. The objectives of this study were to estimate intakes of individual, classes and total flavonoids in the US adults; to evaluate the effects of socio-demographic factors on the flavonoid consumption patterns; and to establish major dietary sources of flavonoids. We calculated flavonoid intakes using the most updated USDA flavonoid and isoflavone databases, and the National Health and Nutrition Examination Survey (NHANES) III 24-h dietary recall (DR). Estimated mean total flavonoid intake by US adults was 344.83 ± 9.13 mg/day. The flavan-3-ols (191.99 ± 6.84 mg/day) were the most abundant flavonoid class. The three most dominant individual flavonoids were catechin, epicatechin and polymers. Tea, wine, beer, citrus fruits and apples were the most important sources of total flavonoid intakes in the US adults.
