Blueberries May Help Patients With Hypertension

Blueberries May Help Patients With Hypertension

Blueberry Heart – JA7955
A study published in the Journal of the Academy of Nutrition and Dietetics found that daily blueberry consumption improved blood pressure and reduced arterial stiffness in postmenopausal women.  Researchers performed a double-blind study on a group of women, ages 45-65, with pre- and stage 1-hypertension.  Half the participants were given daily servings of freeze-dried blueberry powder, while the other half received a placebo.  After eight weeks, blueberry eaters showed significant decreases in systolic and diastolic blood pressure as well as an increase in levels of nitric oxide, a chemical known to relax and widen blood vessels.
Though the changes in blood pressure were modest compared to traditional blood pressure medications, a growing number of patients are turning to more natural remedies.  Blueberries in particular have demonstrated anti-hypertensive and vascular-protective abilities which other fruits have not been able to exhibit.
