According to a British scientists, a glass of beet juice a day can reduce the blood pressure by up to 7 millimeters of mercury (manometric unit of pressure).
Beetroot has unusually very high levels of nitrates, which, as it turned out of a series of studies, reduces blood pressure. One of those studies revealed that only a glass of beetroot juice a day may reduce blood pressure.
According to those results, nitrates which are found in beetroot, when consumed are turned into nitric oxide gas (NO) and that gas relaxes and dilates blood vessels and thus helps blood flow.
The amount of beet juice used in the study contained about 0.2 g of nitrate. Same amount of nitrate can be found in a large bowl of salad or two beetroots. High nitrate concentrations, except in beet, can be found in celery, cabbage and other leafy vegetables, such as spinach and lettuce.
High blood pressure affects many people and at least one third of those patients do not know they have it, which is very dangerous because high blood pressure is a major risk factor for heart disease, kidney failure and stroke.
For people who have high blood pressure, to kept it under control, it is necessary to change lifestyle and to reduce salt intake and alcohol, and of course, to be physically active, to stay fit.
