Summer is the perfect time to indulge in delicious blueberries—and help your heart at the same time. A daily one-cup serving of blueberries may lower blood pressure and potentially delay the
progression of prehypertension to hypertension, reducing your risk of coronary heart disease, according to a recent study in the Journal of the Academy of Nutrition and Dietetics.
For eight weeks, 48 postmenopausal women with pre- and stage-1 hypertension were given either the powder equivalent of one cup of fresh berries, or a placebo powder during a trial at Florida State University. Those who consumed blueberry powder experienced a decrease in blood pressure and a reduction in arterial stiffness.
