Soy food consumption is associated with lower risk of coronary heart disease in Chinese women.Previous studies have demonstrated a beneficial effect of soy food intake on heart health. Many mechanisms have been formulated to explain this protective effect, such as improving of lipid profiles, lowering of blood pressure, improving vascular reactivity and inhibition of LDL cholesterol oxidation.
Xianglan and co-workers were the first to prospectively explore the effect of soy food intake on incidences of coronary heart disease among participants of the Shanghai Women's Health Study. Information on usual intake of soy foods was obtained form 64.915 women at baseline by using food-frequency questionnaire. This questionnaire covered soy foods such as tofu, soymilk, bean curd and fried bean curd.
The authors concluded that soy food consumption was inversely associated with the risk of coronary heart disease.
