Daily a glass of beet juice for high blood pressure
Daily, a glass of beet juice can reduce blood pressure in the long run. Researchers at Wake Forest University in Winston-Salem discovered this during a study. In addition, subjects with heart failure could significantly improve their stamina. Responsible for this effect is inorganic nitrate, which is abundant in other vegetables.
Everything has become an herb
"One herb has grown against everything," is the name of an ancient proverb of natural medicine. For millennia, the knowledge of natural medicine has been passed on to the next generation. In modern times, many scientists are trying to rediscover the knowledge once it has been supplanted by the pharmaceutical industry and belief in the medicine of the tablets. Researchers at Wake Forest University in Winston-Salem have found in a comparative study that a daily beet juice can significantly improve the performance of patients with heart failure. In addition, better blood pressure values were found at rest and under stress.
Inorganic nitrate content causing
The beet is rich in inorganic nitrate. This circumstance is the reason why an increase in performance has been observed in many studies. A new US study has shown that heart failure patients with preserved ejection fraction (FHREP) can have a positive effect if they regularly drink beet juice. After only one week of daily consumption, systolic blood pressure was measurably improved. The services in the test were also visibly improved.
A total of 20 hypertensive patients with HFPS in NYHA stages 2 and 3 and 69 in middle age participated in the pilot study. First, participants received a single dose of beet juice or placebo in a cross-over design. After the so-called washout phase, all candidates participated in the healing of the juice for a week. Each 70 ml daily ration contained exactly 6.1 mmol of nitrate.
After one week, the aerobic resistance in the submaximal load increased from 363 seconds to 449 seconds. This means that performance increased by 24%. However, the single dose in the placebo comparison showed no effect. The heart rate and oxygen consumption during exercise ECG remained almost identical. (Link Study)
Stress test showed visible success
It was evident that in both treatments (the concentration of nitrate and nitrite, once during the week) in plasma had increased measurably. Systolic blood pressure fell from 134 to 120 mmHg after one week. The stress test also showed improvement after one week. Although this was not as pronounced (from 166 to 159 mmHg), but still showed a tendency to point.
Although the study was conducted with only a small number of participants and the comparison period was also quite short, the study should have a "significant therapeutic consequence," according to study director Joel Eggebeen of Wake Forest University in Winston-Salem . For reduced performance is the main symptom of heart failure. Patients suffer from restrictions in everyday life. There are no drugs that achieve performance gains. Only resistance training could help patients so far. Therefore, physicians write, "Our study suggests that chronic ingestion of NO by ingestion of inorganic nitrate through diet may improve submaximal tolerance to exercise."
Previous studies point in the same direction
An earlier study pointed in a similar direction. The single use of beet juice in the placebo comparison led to an increased exercise tolerance of patients. In the research, however, the nitrate content was twice as high as this.
Pills do not help
And one more thing was noticeable. In contrast, no or even negative effects were achieved with organic nitrate. This could be, according to the scientists, that "a different pharmacokinetics" was present. That is, organic nitrate rapidly leads to a release of large amounts of NO. "Inorganic nitrate, on the other hand, provides a slower NO formation and hence a smaller but sustained vasodilatation," write the researchers. In addition, "NO release is targeted more specifically to hypoxic regions."
But why does the gift of beet juice work so well? Scientists suspect that after consumption "systemic vascular resistance lowers." In addition, the study authors suspect that the distribution of blood flow and thus the circulation of the muscles is promoted. The study should be used to conduct larger and larger surveys. Finally, "the secret must be revealed for the benefit of the patient." (Sb)
