9Helps in reducing menopausal symptoms

Soy contains natural isoflavones which are a class of phytoestrogens. These isoflavones act like a weak estrogen in the body. During menopause, estrogen levels decrease which then leads to emergence of symptoms like hot flashes. This can be reduced with the help of the natural estrogens in soy.

As per studies, soy can play a beneficial role in menopause. A review of 35 studies showed how soy isoflavone supplements increased the estradiol (estrogen ) levels in postmenopausal women by around 14%. In another review of 17 studies which involved women taking an average dose of 54 mg of soy isoflavones per day for 12 weeks recorded a 20.6% drop in hot flashes. These women also experienced a 26.2% decrease in symptom severity.
