Objective: To estimate flavonoid intake in the Australian population. Design: Flavonoid consumption was estimated from 24-hour recall data and apparent consumption data using US Department of Agriculture flavonoid composition data. Subjects: The National Nutrition Survey 1995 assessed dietary intake (24-hour recall) in a representative sample (n ¼ 13 858) of the Australian population aged 2 years and over. Results: Analysis of the 24-hour recall data indicated an average adult intake (. 18 years) of 454 mg day 21 (92% being flavan-3-ols). Apple was the highest quercetin source until age 16-18 years, after which onion became an increasingly important prominent source. Variations in hesperetin consumption reflected orange intake. Apple, apricot and grapes were the major sources of epicatechin and catechin for children, but subsided as wine consumption increased in adulthood. Wine was the main source of malvidin. Naringenin intake remained static as a percentage of total flavonoid intake until age 19-24 years, corresponding to orange intake, and then increased with age from 19 -24 years, corresponding to grapefruit intake. Apparent dietary flavonoid consumption was 351 mg person 21 day 21 , of which 75% were flavan-3-ols. Black tea was the major flavonoid source (predominantly flavan-3-ols) representing 70% of total intake. Hesperetin and naringenin were the next most highly consumed flavonoids, reflecting orange intake. Both 24-hour recall and apparent consumption data indicated that apigenin intake was markedly higher in Australia than reported in either the USA or Denmark, presumably due to differences in consumption data for leaf and stalk vegetables and parsley. Conclusions: Tea was the major dietary flavonoid source in Australia. Flavonoid consumption profiles and flavonoid sources varied according to age. More consistent methodologies, survey tools validated for specific flavonoid intakes and enhanced local flavonoid content data for foods would facilitate better international comparisons of flavonoid intake.

“…More recent studies have estimated individual flavonoid or flavonoid profile intakes in the USA 18 , Denmark 19 , Holland 20 , Finland 21 , France 22 , Greece 23 , Japan 24 and Spain 25 , although the dietary intake methodologies vary substantially. The present study was initiated to add an Australian perspective to international comparisons.…”

“…So far, there has not been the population dietary flavonoids intake survey in our country. Tea, onions, and apples are the most predominant food sources of flavonols in The Netherlands (Hertog et al, 1993), Denmark (Justesen et al, 1997), and United States (Rimm et al, 1996). Variations in the dietary sources are influenced by such factors as feeding habits and cultural changes.…”

The objective of this work was to quantify the potential anticancer flavonoids (quercetin, kaempferol, isorhamnetin, apigenin and luteolin) by a rapid, reliable and accurate reverse phase high performance liquid chromatography (RP-HPLC) among 100 edible vegetables and fruits commonly consumed in Harbin city, China. The predominant flavonoids found in the largest abundance in all of the analyzed foods were kaempferol, followed by luteolin and quercetin. Potherb mustard, lettuce (red), toona leaf, celery leaf, garlic, garlic stalk, apple, date, ginger (with peel) and radish leaf (red root, small) were major food sources of flavonols and flavones. This study contribute to the establishment of China's flavonoid database and provide a basis for the assessment of the daily flavonoid intake.

“…According to Tomás-Barberán and Clifford (2000), the consumption of the entire fruit could even supply five-fold higher amounts of flavanones. These levels are quite high compared with the mean flavonol intake which has been estimated to about 25 mg=day in several European countries (Hertog et al, 1993;Pietta et al, 1996;Justesen et al, 1997). In a recent study on the polyphenol intake in Finland, hesperetin was reported to be the most highly consumed flavonoid with an intake of 28.3 mg=day, equivalent to 30% of the total flavonoid intake (Kumpulainen, 2001).…”

Objective: Flavanones are polyphenols specific of citrus fruits, where they are present in high amounts. Although citrus fruits and juices are widely consumed in the world, little information has been published on flavanone bioavailability in humans. The aim of the present study was to determine the nature of the circulating metabolites, the plasma kinetics and the urinary excretion patterns of the flavanones, hesperidin and narirutin. Design: After an overnight fast, five healthy volunteers ingested 0.5 or 1 l of a commercial orange juice providing 444 mg=l hesperidin and 96.4 mg=l narirutin, together with a polyphenol-free breakfast. Blood was sampled at 10 different timepoints over a 24 h period. Urine was collected for 48 h, in five fractions. Results: Flavanones metabolites appeared in plasma 3 h after the juice ingestion, reached a peak between 5 and 7 h, then returned to baseline at 24 h. The peak plasma concentration of hesperetin was 0.46 AE 0.07 mmol=l and 1.28 AE 0.13 mmol=l after the 0.5 and 1 l intake, respectively. It was lower for naringenin: 0.20 AE 0.04 mmol=l after the 1 l dose. The circulating forms of hesperetin were glucuronides (87%) and sulphoglucuronides (13%). For both flavanones, the urinary excretion was nearly complete 24 h after the orange juice ingestion. The relative urinary excretion was similar for hesperetin and naringenin and did not depend on the dose: values ranged from 4.1 AE 1.2 to 7.9 AE 1.7% of the intake. Conclusions: In case of a moderate or high consumption of orange juice, flavanones may represent an important part of the pool of total polyphenols present in plasma.
