Phytoestrogener

Recommended Posts

Wikipedia sier at soya isolat inneholder phytoestrogen:

Soy protein contains phytoestrogens, which bind to estrogen receptors in the body.


[...]

In human beings, phytoestrogens are readily absorbed, circulate in plasma and are excreted in the urine. Metabolic influence is different from that of grazing animals due to the differences between ruminant versus monogastric digestive systems.[18]
Males
A 2010 meta-analysis of fifteen placebo-controlled studies said that "neither soy foods nor isoflavone supplements alter measures of bioavailable testosterone concentrations in men."[28] Furthermore, isoflavone supplementation has no effect on sperm concentration, count or motility, and leads to no observable changes in testicular or ejaculate volume.[29][30]
A soy phytoestrogen-rich diet can substantially reduce testosterone levels in male rats in laboratory studies, while possibly having protective benefits against prostate cancer.[31][32]


Jeg prøver å forstå hva dette betyr. Hva vil det si i praksis, liksom?
