Research has found that having a glass of beetroot juice each day could lower the blood pressure of people suffering from hypertension. The study, which was conducted at Queens Mary University of London, found that patients suffering from hypertension who drank 250ml of beetroot juice a day, saw their blood pressure levels return to the ‘normal’ range by the completion of the study.
Beetroot juice reduces high blood pressure, because it contains high amounts of nitrate. The digestive system automatically converts nitrate NO3 to nitric oxide (NO) and biologically active nitrate (NO2). The role of nitric oxide in the body is to relax and widen the blood vessels, which in turn makes it easy for blood to flow through the body and reduces hypertension.
The study carried out at Queen Mary University of London involved 64 participants, aged 18 to 85. The participants spent four weeks consuming beetroot juice. They were also monitored two weeks prior to the experiment, as well as two weeks after.
Two groups were split randomly. One group took 250 ml of inorganic beetroot juice daily and the other group, the placebo group, took 250 ml of nitrate-free beetroot juice.
Blood pressure levels were reduced by 8/4 mmHg for participants in the group taking inorganic beetroot juice. They also saw a 10 to 20% increase in their artery stiffness, dilation capacity and blood vessel widening. Unlike the placebo group, where there were no changes to the blood pressure, artery stiffness and blood vessel function.
The study by the Queen Mary University of London suggests that drinking a glass of 250ml of beetroot juice, on average, daily will reduce your blood pressure by 8/4 mmHg. For many of the participants, this brought their levels back to normal.
Drinking beetroot juice can reduce blood pressure levels after an hour. After ingestion, hours later blood pressure will reach the lowest point and will continue to have an effect on the levels up to 24 hours after taking your beetroot juice.
There are more juices that are known to have an improving impact on people with hypertension. Drinking natural drinks that contain nitrate, folate, vitamin C, antioxidants and bioactive compounds will reduce your systolic and diastolic blood pressure.
Please speak to your health professional before taking these remedies. Your doctor will be best placed to advise on the most appropriate treatment for your hypertension.
