A small study has demonstrated that the blood-pressure lowering effects of Beet-root juice by increasing the intake of dietary nitrates.
Dr Amrita Ahluwalia (Barts and the London School of Medicine and Dentistry, UK) and colleagues have previously shown that beet juice, after coming into contact with human saliva, increases levels of plasma nitrate and nitrite and leads to significant blood-pressure decreases in healthy volunteers.
In their latest study, published online April 15, 2013 in Hypertension, Ahluwalia and colleagues from the Queen Mary University of London, UK turned again to beetroot, which, along with green leafy vegetables, has high concentrations of inorganic nitrate.
The authors tested the beet-juice effects in 15 hypertensive, drug-naive patients, randomized to either 250 mL of inorganic nitrate-rich beetroot juice or an equal volume of water. The “dose” of juice elevates nitrite levels approximately 1.5 fold.
In patients who drank the juice, systolic blood pressure dropped by a mean of 11.2 mm Hg between three and six hours after consumption (vs 0.7 mm Hg in subjects who drank water). By 24 hours, clinic systolic BP remained significantly lower in the beet-juice group and roughly 7.2 mm Hg lower than baseline. Peak drop in diastolic BP also occurred within the first six hours, dropping by a mean of 9.6 mm Hg. Pulse-wave velocity also decreased in the beet-juice group, but not in the controls.
