Beetroot and Blood Pressure

According to a 2012 study, drinking beetroot juice lowers blood pressure in healthy people. Two randomized, placebo-controlled trials were carried out in people without blood pressure problems. "Randomized" means the participants were selected at random, and "placebo-controlled" means there was a comparison group that did not consume beetroot juice. In all participants, blood pressure was measured over a 24-hour period after consumption. Eighteen participants received either beetroot juice at different concentrations (0, 100, 250 and 500 g), while another 14 people received bread enriched with beetroot, bread with white beetroot, and control bread. The results showed that beetroot juice significantly lowers both systolic and diastolic blood pressure. The breads enriched with beetroot or white beetroot also lowered blood pressure noticeably, though to a lesser extent.

In another study, healthy people had their blood pressure reduced by about 10 mmHg three hours after drinking 500 ml of beetroot juice - at the same time, the nitrite concentration in plasma increased.

It's actually the nitric oxide (NO) in beetroot that can have so many beneficial effects. It positively influences many processes in the body: NO increases oxygen levels in the blood, causes blood vessels to widen and thus improves oxygen delivery to tissues. NO regulates the clumping of blood platelets (thrombocytes) and thereby reduces the risk of atherosclerosis. And NO supports the immune system.

But the nitrite found in beetroot is also important. As early as the 1970s, F. Murad discovered that organic nitrates can dilate blood vessels. Another pharmacologist, R. F. Furchgott, found a factor in the inner lining of blood vessels that causes the muscle tension in the vessel wall to relax. At the end of the 1980s this factor was identified by Furchgott and by L. J. Ignarro: it was NO. In 1998 these three researchers received the Nobel Prize for their findings that NO can play a decisive role in treating cardiovascular diseases and their consequences.

Soon afterward, in 1999, INOmax gas was approved by the FDA in the USA. It is a mixture of different nitrogen monoxides used to lower blood pressure in newborns with pulmonary hypertension (the lungs fail). Today, NO is also used as supportive treatment during heart surgery.

Concentrated organic beetroot juice is available from the Austrian organic fruit juice producer fitrabbit. The nitrate content is about five times that of standard commercially available beetroot juice. The producer recommends 100 ml per day, which is equivalent to half a litre of standard commercially available juice. In the convenient 3-litre box, it keeps for months without refrigeration.
