A glass of beetroot juice for high blood pressure every day
A glass of beetroot juice every day can lower blood pressure sustainably, as a pilot study by the Wake Forest University in Winston-Salem showed. This is due to inorganic nitrate, which can also be found in other vegetables. We report in the following article how much patients should actually drink every day.
An herb is grown against everything
"There is an herb against everything," is an old saying in naturopathy. The knowledge of natural medicine has been passed on to the next generation for thousands of years. In modern times, numerous scientists are trying to rediscover knowledge after it has been supplanted by the pharmaceutical industry and belief in pill medicine. In a comparative study, researchers at Wake Forest University in Winston-Salem found that beetroot juice enjoyed daily can significantly improve the performance of heart failure patients. In addition, improved blood pressure values were seen at rest and under stress.
Inorganic nitrate content is the cause
Beetroot is rich in inorganic nitrate. This is the reason why an increase in performance has been observed in many studies. A new study from the USA showed that patients with heart failure with preserved ejection fraction (HFPEF) can achieve a positive effect if they drink the beet juice regularly. After just one week of daily consumption, it was shown that the systolic blood pressure improved measurably. The performance in the test was also visibly improved.
A total of 20 hypertonic HFPEF patients in NYHA stage 2 and 3 and in the middle age of 69 years participated in the pilot study. First, the subjects were given a single dose of beetroot or placebo juice in a cross-over design. After a so-called washout phase, all subjects took part in the one-week juice cure. Each 70 ml daily ration contained exactly 6.1 mmol nitrate.
After a week the aerobic endurance had increased from 363 to 449 seconds with submaximal exertion. This means that performance has increased by 24 percent. However, the single administration in the placebo comparison showed no effect. The heart rate and the oxygen intake during the exercise ECG remained almost identical. (Study link)
Stress test showed visible success
It was evident that with both doses (the one-week and the one-time) nitrate and nitrite concentrations in the plasma had increased measurably. After a week, the systolic blood pressure dropped from 134 to an incredible 120 mmHg. The stress test also showed an improvement after one week. Although this was not as pronounced (from 166 to 159 mmHg), it nevertheless showed a trend.
Although the study was undertaken with only a few participants and the comparison period was also very short, the study leader Joel Eggebeen from Wake Forest University in Winston-Salem believes that the study should have an “important therapeutic consequence”. Because reduced performance is the main symptom of heart failure. Patients suffer from everyday restrictions. There are no drugs that can improve performance. Only endurance training has so far been able to help patients. This is why the doctors also write: "Our study suggests that a chronic NO intake through the intake of inorganic nitrate through food can improve the submaximal tolerance to exercise".
Previous studies point in the same direction
A previous study pointed in a similar direction. The one-time consumption of beetroot juice in the placebo comparison led to an increased stress tolerance of the patients. In the research work, however, the nitrage content was twice as high as this one.
Pills don't help
And another was striking. In contrast, no or even negative effects were achieved with organic nitrate. According to the scientists, this could be due to the fact that “there are different pharmacokinetics”. Organic nitrate quickly leads to the release of large amounts of NO. "Instead, inorganic nitrate ensures slower NO formation and thus less, but persistent vasodilation," the researchers write. In addition, "the NO release is directed more specifically into hypoxic regions".
But why does the beetroot juice work so well? The scientists suspect that “after consumption, the systemic vascular resistance is reduced”. In addition, the study authors suspect that the distribution of blood flow and thus blood flow to the muscles is promoted. The study should be used to undertake further, larger research. Finally, "the secret should be revealed for the benefit of the patient". (sb)
