Fs. Dalais et al., URINARY-EXCRETION OF ISOFLAVONOID PHYTOESTROGENS IN CHINESE AND ANGLO-CELTIC POPULATIONS IN AUSTRALIA, Nutrition research, 18(10), 1998, pp. 1703-1709
The purpose of this cross-sectional study was to compare the urinary e
xcretion of phytoestrogens in Australians of Chinese and Angle-Celtic
origins. Urine samples from individuals already participating in two c
ross-cultural studies on food habits and health status, were used in o
rder to measure excretion of the two isoflavonoid phytoestrogens genis
tein and daidzein. The mean (+/- SEM) 24 h excretion of genistein and
daidzein, was 614 +/- 202 nmol and 688 +/- 218 nmol in the Chinese pop
ulation and 107 +/- 31 nmol and 164 +/- 63 nmol in the Angle-Celtic po
pulation (p<0.001) respectively. Differences were also observed in foo
d consumption where cereal and legume consumptions were significantly
higher in the Chinese population (p<0.001). The urinary excretion of p
hytoestrogen in the Melbourne Chinese and Anglo-celtic is consistent w
ith excretion rates of other populations. (C) 1998 Elsevier Science In
