Soy diet has been suggested to have antihypertensive effect in animal studies. The present study examined the cross-sectional relationship between blood pressure and intake of soy products and other food groups in Japanese men and women.
Blood pressure was measured in Japanese 294 men and 330 women (246 premenopausal and 84 peri- and postmenopausal women) who participated in a health check-up program provided by a general hospital. Intake of various food groups and nutrients was estimated from a validated semiquantitative food frequency questionnaire.
In men, soy product intake was inversely significantly correlated with diastolic blood pressure (r = -0.12, P = 0.04) after controlling for age, total energy, smoking status, body mass index, and intake of alcohol, salt and seaweeds. The correlation of soy product intake with systolic blood pressure was of borderline significance (r = -0.10, P = 0.09). Systolic blood pressure was inversely correlated with intake of vegetables (r = -0.12, P = 0.04) and dairy products (r = -0.12, P = 0.05). There were no significant correlations between soy product intake and diastolic blood pressure in women.
These results indicate a mild effect of soy intake on blood pressure reduction in men.
动物研究表明大豆饮食具有降压作用。本研究调查了日本男性和女性的血压与大豆制品及其他食物组摄入量之间的横断面关系。
对参与一家综合医院提供的健康检查项目的294名日本男性和330名女性（246名绝经前女性以及84名围绝经期和绝经后女性）测量血压。通过一份经验证的半定量食物频率问卷估算各种食物组和营养素的摄入量。
在男性中，在控制了年龄、总能量、吸烟状况、体重指数以及酒精、盐和海藻的摄入量后，大豆制品摄入量与舒张压显著负相关（r = -0.12，P = 0.04）。大豆制品摄入量与收缩压的相关性接近显著（r = -0.10，P = 0.09）。收缩压与蔬菜摄入量（r = -0.12，P = 0.04）和乳制品摄入量（r = -0.12，P = 0.05）呈负相关。在女性中，大豆制品摄入量与舒张压之间无显著相关性。
这些结果表明大豆摄入对男性血压降低有轻微作用。
