March 22, 2002 -- Two glasses of orange juice a day lowers blood pressure, a new study suggests. It doesn't mean that OJ is the cure for what ails you.It does mean that a good diet is crucial -- especially for heart patients.High blood pressure isn't good for anybody.he blood-pressure decrease we saw is definitely clinically relevant, says Carla McGill, PhD, RD, a nutrition scientist at Tropicana. If we could reduce blood pressure by this much it would be very good for all patients.. At the end of the study, the patients stopped drinking orange juice for two weeks.
Blood pressure improves. Beets are rich in nitrates, which the body converts to nitric oxideâa compound that relaxes and dilates blood vessels, turning them into superhighways for your nutrient- and oxygen-rich blood. That means better circulation, and possibly lower blood pressure. A very small study from 2012 found that 13 men who drank just one glass of beet juice temporarily lowered their systolic blood pressure by an average of 4 to 5 points. (Note: the study was funded by a beet juice manufacturer.) Another study published in Hypertension in 2008 (which didn't receive funding from beet-juice makers) found that folks who drank the red root juice had a 10 mm Hg drop in blood pressure and less blood clotting three hours later, compared to those who drank water.
