Abstract Flavonoids are strong antioxidants that occur naturally in foods and can inhibit carcinogenesis rodents. Accurate data on population‐wide intakes of flavonoids not available. Here, using the Dutch National Food Consumption Survey 1987–1988, we report intake potentially anticarcinogenic quercetin, kaempferol, myricetin, apigenin, luteolin among 4,112 adults. The flavonoid content vegetables, fruits, beverages was determined by high‐performance liquid chromatography. In all subjects,...

Quercetin is a strong antioxidant and major dietary flavonoid. Epidemiological studies suggest that consumption of quercetin protects against cardiovascular disease, but its absorption in man controversial. We fed nine subjects single large dose onions, which contain glucose conjugates quercetin, apples, both non‐glucose glycosides, or pure quercetin‐3‐rutinoside, the glycoside tea. Plasma levels were then measured over 36 h. Bioavailability from apples rutinoside was 30% relative to onions....

Flavonoids are antioxidants present in plant foods. They occur mainly as glycosides, i.e. linked with various sugars. It is uncertain to what extent dietary flavonoid glycosides absorbed from the gut. We investigated how nature of sugar group affected absorption one major flavonoid, quercetin. Quercetin glucose, quercetin glucoside and rutinose, rutinoside, both widely When we fed these compounds nine volunteers, peak concentration (Cmax) plasma was 20 times higher reached (Tmax) more than...
Total flavonol and flavone contents of foods have been determined with validated state-of-the-art methods. Quercetin dominates, levels found in vegetables fruits are below 10 mg kg−1. However, high concentrations onions (300 kg−1), kale (450 broccoli (100 beans (50 apples blackcurrants (40 tea (30 l−1). The dietary intake flavonols varies 10-fold between countries (6–60 day−1). Flavones minor importance the diet. Tea, wine most important sources flavanols, but there gaps our knowledge on...

Catechins, compounds that belong to the flavonoid class, are potentially beneficial human health. To enable epidemiological evaluation of these compounds, data on their contents in foods required.

Procyanidins (PCs) are highly abundant phenolic compounds in the human diet and might be responsible for health effects of chocolate wine. Due to low absorption intact PCs, microbial metabolism play an important role. So far, only a few studies, with crude extracts rich PCs but also containing multitude other compounds, have been performed reveal PC metabolites. Therefore, origin metabolites remains questionable. This study included vitro fermentation purified dimers microbiota. The main...
Abstract Plant phenols are mostly products of the phenylpropanoid pathway and comprise a large variety compounds: cinnamic acids, benzoic flavonoids, proanthocyanidins, stilbenes, coumarins, lignans lignins. They strong antioxidants might prevent oxidative damage to biomolecules such as DNA, lipids proteins which play role in chronic diseases cancer cardiovascular disease. may interfere with all stages process, potentially resulting reduction risk.
