The phytoestrogens examined included soya isoflavones, lignans and enterolignans including equol and coumestrol into the analysis.
Although using pure unconjugated isoflavones represents a more controlled experimental setup, using a soy-based diet constitutes a more relevant model of phytoestrogen exposure for humans, cattle, and rodents.
Effects of the phytoestrogen genistein on the circulating soluble receptor activator of nuclear factor kappaB ligand-osteoprotegerin system in early postmenopausal women.
Bioavailability studies confirmed that most phytoestrogens are readily absorbed by humans, but this varies somewhat, possibly due to a variability in gut microflora, diet and metabolism.
Phytoestrogens are members of the phytochemical family with naturally occurring oestrogenic activity.
Soy supplements, which are rich in phytoestrogens, are growing in popularity as a nonpharmacologic alternative, Melanie R.
Data from four randomized, controlled trials on phytoestrogens suggest that soy isoflavones may affect verbal memory (immediate recall of a story) and executive function (ability to plan).
Phytoestrogen (plant derived estrogen) can apparently substitute for estrogen in the body, but has a far weaker effect and apparently no side effects.
Phytoestrogens appear to exert their beneficial effects by helping to control the way in which oestrogen is transported in the blood.
Although the data are limited for developmental effects of phytoestrogens, the similarity of DES and phytoestrogen effects in newborn rodents should be considered a cautionary note for the developmentally later exposure that occurs with soy infant formula.
