Soy food consumption may reduce the risk of fracture in postmenopausal women, particularly among those in the early years following menopause, according to a review of 24,403 postmenopausal women.

Researchers examined the relationship between soy food consumption and fracture incidence in 24,403 postmenopausal women who had no history of fracture or cancer. The women had participated in the Shanghai Women’s Health Study between March 1, 1997 and May 23, 2000.

Soy food intake was assessed at the beginning of the study and was reassessed during follow-up through in-person interviews using a validated food frequency questionnaire.

During a mean follow-up of four-and-a-half-years, 1,770 incident fractures were identified. Postmenopausal women who ate the most soy protein had a 37% lower risk of bone fracture compared to women who consumed the least soy.
