Plant polyphenols have various health effects. Genistein, which is abundant in soybeans,
and epigallocatechin-3-gallate, which is abundant in green tea, are major flavonoids, a …

Flavonoids are polyphenolic compounds ubiquitously foundin human diets. We have
studied the association between urinary excretion of flavonoids and the intake of fruits and …

Soy products contain high amounts of isoflavonoids, which have been shown to exhibit
possible cancer-protective properties. Chinese populations in Asia, in particular, have a high …

Purpose The aim of this study was to determine the association between urinary
isoflavonoid (genistein, daidzein, and the daidzein metabolites O-desmethylangolensin (O …

Background: Isoflavonoids (IFL) may protect against chronic diseases, including cancer. IFL
exposure is traditionally measured from plasma (PL), but the reliability of urine is uncertain …

Polyphenols, commonly contained in fruits and vegetables, have long been associated with
a protective role against multiple diseases and adverse health effects. Generally, in vitro and …

Isoflavonoids are a group of biologically active phytochemicals that humans are exposed to
mainly through soy food intake. Because of the similar chemical structure of these …

Background Whether soy food consumption may protect against coronary heart disease
(CHD) remains controversial. No previous study has used biomarkers of soy intake in …

Dietary isoflavone and lignan phytoestrogens are potential chemopreventive agents. This
has led to a need to monitor exposure to these compounds in human populations and to …

Background: Epidemiologic studies have suggested that a higher intake of flavonoids may
be associated with lower risk of ischemic heart disease. However, the traditional estimation …
