In the study of "Long-term dietary habits affect soy isoflavone metabolism and accumulation in prostatic fluid in caucasian men. by Hedlund TE, Maroni PD, Ferucci PG, Dayton R, Barnes S, Jones K, Moore R, Ogden LG, Wähälä K, Sackett HM, Gray KJ., posted in US National Library of Medicine National Institutes of Health, researchers found that Equol production was not linked to age, BMI, or the consumption of
yogurt, dairy, fruit, or American-style fast food. Daidzein and its
metabolites (but not genistein) were typically present at higher levels
in prostate fluid than plasma (median = 4-13 times that in plasma). In
conclusion, our data suggest that the ability of Caucasian men to
produce equol is favorably influenced by the long-term consumption of
high amounts of soy
and the consumption of meat. Last, the high concentrations of
isoflavonoids in prostatic fluid increases the potential for these
compounds to have direct effects in the prostate.
