Isoflavones are the most common type of plant estrogen. Soybeans are an abundant source of the most beneficial isoflavones known, daidzen and genestein, which both have a positive effect on breast health.
Features
Because of their chemical structure, isoflavones can mimic estrogen in the body, especially in breast tissue.
Function
Estrogen receptors exist throughout the body, especially in the breasts, vagina and uterus. Estrogen plays a crucial role in the reproductive system, but too much can trigger cancer growth.
Effects
Isoflavones attach to estrogen receptors in breast tissue cells, which prevents other estrogen from doing the same. Because isoflavones are a weaker form of estrogen, they do not stimulate cell division like stronger forms do, thereby minimizing the risk of cancer growth.
Study Findings
Frequent consumption of soy isoflavones is a major protective dietary factor against breast cancer, according to a study led by Dr. H.P. Lee of the National University of Singapore.
Sources
Soy isoflavones can be obtained by eating soy foods or taking soy isoflavone supplements.
