Comparison of ABTS/DPPH assays to measure antioxidant capacity in popular antioxidant-rich US foods
Abstract To evaluate the comparability of the two most common radical scavenging assays using 2,2′-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) and 1,1-diphenyl-2-picrylhydrazyl (DPPH)Expand
Daily consumption of phenolics and total antioxidant capacity from fruit and vegetables in the American diet
The daily intake of total phenolics, total flavonoids and antioxidants in the American diet was estimated from the most common 34 fresh fruit and vegetables and their daily consumption data. Among 14Expand
Estimated dietary flavonoid intake and major food sources of U.S. adults.
The proposed relation between flavonoid intake and the prevention of chronic diseases needs further investigation using the estimates introduced in this study. Expand
Quantification of polyphenolics and their antioxidant capacity in fresh plums.
A positive relationship (correlation coefficient r (2)() = 0.977) was presented between total phenolics and VCEAC, suggesting polyphenolics would play an important role in free radical scavenging, and Beltsville Elite B70197 showed the highest amounts of total phenolic and total flavonoids and the highest VCEac.

Is consumption of breakfast associated with body mass index in US adults?
RTEC breakfast consumption, associated with a desirable macronutrient profile for preventing obesity, predicted weight status in women, but not in men, according to data from the National Health and Nutrition Examination Survey, 1999-2000. Expand
Berry anthocyanins suppress the expression and secretion of proinflammatory mediators in macrophages by inhibiting nuclear translocation of NF-κB independent of NRF2-mediated mechanism.
BBA, BKA and BCA exert their anti-inflammatory effects in macrophages, at least in part, by inhibiting nuclear translocation of NF-κB independent of the NRF2-mediated pathways. Expand
Superoxide radical scavenging activity of the major polyphenols in fresh plums.
The effect of polyphenols among different varieties of plums on superoxide radical scavenging activity (SRSA) was studied by an enzymatic method and their IC(50) values were determined, which indicated that flavonoids might contribute to the total SRSA more directly than otherpolyphenols. Expand
Consideration on equivalent chemicals in total phenolic assay of chlorogenic acid-rich plums
Abstract The spectrophotometric characteristics of chemicals used as equivalents in Folin–Ciocalteu method were evaluated. Gallic acid and (+)-catechin showed the highest response at the range ofExpand
Serum C-reactive protein concentrations are inversely associated with dietary flavonoid intake in U.S. adults.
It is demonstrated that intake of dietary flavonoids is inversely associated with serum CRP concentrations in U.S. adults, and intake of flavonoid-rich foods may thus reduce inflammation-mediated chronic diseases. Expand
Tea is the major source of flavan-3-ol and flavonol in the U.S. diet.
It is found that tea is the major dietary source of flavonoids in U.S. adults; tea consumers differ from those of tea nonconsumers in sociodemographics, health-related behaviors, and dietary and beverage sources of Flavonoid intake. Expand
