Daily Blueberry Consumption Improves Blood Pressure And Arterial Stiffness In Postmenopausal Women With Pre- And Stage 1-hypertension: A Randomized, Double-blind, Placebo-controlled Clinical Trial
Notes for this study:
||Brachial-ankle PWV decreased from 1498 to 1401 cm/s but carotid-femoral PWV remained unchanged.
|Number of Subjects
48 postmenopausal women with pre- or stage 1 hypertension were given placebo or 22 g (11 g twice daily) freeze-dried blueberry powder for 8 weeks. The powder had 4.69 mg/g anthocyanins and 8.45 mg/g phenolics. After 8 weeks, systolic and diastolic blood pressure dropped to an extent less than that of hypertensive medications. Brachial-ankle pulsewave velocity also dropped. Carotid-femoral pulsewave velocity remained unchanged.
Funding issues for this study:
Supported by the US Highbush Blueberry Council but also by the US Department of Agriculture.
