Beetroot juice increases in heart failure endurance and lowers blood pressure. A glass of beetroot juice daily: patients with heart failure during the study could significantly improve their endurance. Also, the systolic blood pressure fell. The results show that nature can also help with serious illnesses.
“Against Everything is an herb grown”, is an ancient naturopathy saying. Millenniums the knowledge of natural medicine has been transmitted to the next generation. In modern times strive numerous scientists, knowledge rediscovering after being displaced by the pharmaceutical industry and the belief in the pills medicine. Researchers at Wake Forest University in Winston Salem found in a comparative study that a daily enjoyed a beetroot juice can significantly improve the performance of heart failure patients. In addition, improved blood pressure readings showed at rest and stress.

Inorganic nitrate levels cause
Beetroot is rich in inorganic nitrate. This fact is the main reason why in many studies to increased performance could be observed. A new study from the US showed that patients can achieve with heart failure with preserved ejection fraction (HFPEF), a positive effect when drinking the beet juice regularly. After just one week daily consumption showed that systolic blood pressure improved measurably. The performance in the test were also visibly improved.
At the pilot study a total of 20 hypertensive patients HFPEF participated in NYHA class 2 and 3 and a mean age of 69 years. First the volunteers a single dose beetroot juice or placebo was administered in a cross-over design. After a so-called wash-out then all Proanden participating in the weeklong Saftkur. Each 70 ml daily ration contained exactly 6.1 mmol nitrate.
After a week aerobic endurance had increased at the submaximal load of 363 to 449 seconds. This means that the performance has been increased by 24 percent. However, the single dose compared with placebo showed no effect. The frequency of the heart as well as the oxygen uptake during exercise ECGs were virtually identical. (Study Link)
Stress test showed visible results
was visible that both doses (of the week, as the one-time) nitrate and nitrite concentration had increased measurably in plasma. Systolic blood pressure decreased after a week of 134 to an incredible 120 mmHg. When stress test also showed an improvement after one week. This was not as pronounced (from 166 to 159 mmHg), but showed a trend-setting.
Although the study was done only with few participants and also the comparable period turned out quite scarce, the study should have an “important therapeutic consequences” in the opinion of the principal investigator Joel Eggebeen of Wake Forest University in Winston Salem. Because a reduced performance is the main symptom of heart failure. The patients suffer from the limitations in everyday life. There are no drugs that achieve performance gains. Only the endurance training has hitherto help patients. Therefore write the physicians: “Our study suggests that chronic NO delivery by the ingestion of inorganic nitrate via food can improve submaximal exercise tolerance.”
Previous studies point in the same direction
A previous study showed a similar direction. The one-time consumption of beetroot juice compared with placebo had led to increased exercise tolerance of the patients. In the research, however, the Nitra content was twice as high as in this.
Pills do not help
And one thing was striking. With organic nitrate, however, no or even negative effects were achieved. This could be because, according to the scientists that “a different pharmacokinetics” for the purposes. Organic nitrate SIEPSA quickly to the release of large amounts of NO. “Inorganic nitrate provides instead for a slower NO formation and thus for a lower but persistent vasodilation,” the researchers write. In addition, “NO release is targeted conducted in hypoxic regions”.
But why does the beetroot juice gift as well? The scientists suspect that “will reduce the systemic vascular resistance” after consumption. Additionally suggest the study authors, that the distribution of blood flow, and thus the blood flow to the muscles is promoted. The study should be used to make further, more research. Finally, “the secret should be aired for the benefit of patients.” (Sb)
