The antioxidant effects of soy isoflavones may further be beneficial in reduction of certain chronic diseases especially that of the cardiovascular system in postmenopausal women.
Soymilk is beneficial in providing relief from osteoporosis in postmenopausal woman. Osteoporosis is a risk for women in post-menopausal years of age. Often known as brittle bones, loss of calcium contributes the risk of developing this disease.

Curdle soymilk or tofu has antioxidant and hepatoprotective properties which help in reducing oxidative stress and damage. Study suggests that it may be beneficial in preventing liver damage caused by oxidative stress.
