To the Editor:
Flavonoids and other polyphenolic natural compounds have
attracted much attention as candidate cancer preventive and
anticarcinogenic agents, as well as antiatherogenic and antioxidant
compounds (1). Although the public now consumes these
compounds in substantial amounts from dietary sources, food
supplements, and more recently, as "nutraceutical" tablets, their
actual mode of action is not fully defined. The most compelling
hypotheses correlate the biological action of
flavonoids to their ability to mimic natural estrogens
(2)(3) such as estradiol, or to act as
antioxidants (4). Indeed, genistein, a natural soy
isoflavone, is among the most potent known phytoestrogens. The ability
of flavonoids to act as androgen mimics or antiandrogens
