Quercetin is one of the most abundant dietary flavonoids. <ref name="lpi">{{cite web|url=http://lpi.oregonstate.edu/mic/dietary-factors/phytochemicals/flavonoids|title=Flavonoids|publisher=Micronutrient Information Center, Linus Pauling Institute, Oregon State University, Corvallis, OR|date=November 2015|access-date=1 April 2018}}</ref><ref name="usda" /> | Quercetin is one of the most abundant dietary flavonoids. <ref name="lpi">{{cite web|url=http://lpi.oregonstate.edu/mic/dietary-factors/phytochemicals/flavonoids|title=Flavonoids|publisher=Micronutrient Information Center, Linus Pauling Institute, Oregon State University, Corvallis, OR|date=November 2015|access-date=1 April 2018}}</ref><ref name="usda" /> To estimate the average quercetin intake of the U.S. population, data from the flavonoid database was combined with food consumption data from the 2003-2004 National Health and Nutrition Examination Surveys (NHANES). Only individuals who reported consuming foods naturally rich in quercetin were included in the analysis. | ||
The table below presents the estimated daily quercetin intake from natural sources for various U.S. population groups. The overall consumption of quercetin-rich foods led to an estimated average intake of 5.9 mg/person/day, with the 90th percentile at 14.7 mg/person/day. The highest reported individual intake was 258.2 mg/day, observed in the adult male group. It's worth noting that these estimates might be on the conservative side, as quercetin content data is available only for select foods. | |||
