Indication: Blood pressure

Research: Test subjects included 45,694 individuals from the Shanghai Women’s Health Study, between the ages of 40 and 70, with no history of hypertension, diabetes or cardiovascular disease. At baseline, usual intake of soy foods was assessed. Two to three years after baseline, blood pressure (BP) was measured. Using multiple regression models, researchers estimated mean differences in BP linked with a range of soy food intakes.
Results: After adjustment for age, body mass index and lifestyle, as well as other dietary factors, soy protein intake was inversely associated with systolic BP as well as diastolic BP. Specifically, the adjusted mean systolic BP was 1.9 mm Hg lower and the diastolic BP was 0.9 mm Hg lower in women who consumed 25 grams per day or more soy protein than in women whose soy protein intake was less than 2.5 grams per day. The inverse associations between systolic BP and diastolic BP and soy intake were greater with increasing age. Among women greater than 60 years of age, the reductions in systolic BP and diastolic BP were -4.9 mm Hg and -2.2 mm Hg, respectively. The researchers concluded that usual intake of soy foods is inversely associated with both systolic BP and diastolic BP, particularly among older women.
