Phytoestrogen α-Zearalanol in an Animal Model of Menopause

  • Chapter
  • First Online:
Nutrition and Diet in Menopause

Part of the book series: Nutrition and Health ((NH))

Key Points

  • Estrogen has drawn some serious attention regarding its health benefits.

  • The fact that estrogen replacement therapy (ERT) may predispose women to a much higher incidence of breast and endometrial cancers has undoubtedly compromised or jeopardized its clinical application.

  • A plant-derived phytoestrogen, α-zearalanol (α-ZAL), has been proposed as a potential replacement for estrogen.

  • α-ZAL has shown beneficial effects on blood vessels, osteoporosis, and Alzheimer’s disease in animal models of menopause similar with estrogen.

  • It has less proliferating effects on uterus and mammary gland compared to estrogen.
