Even one drink of beetroot juice can lower blood pressure. If everyone drank it, could reduce heart disease deaths overall.

One quick way to lower your blood pressure could be as simple as drinking a glass of beetroot juice, according to a new study.
Researchers from Baker IDI Heart and Diabetes Institute in Melbourne, Australia, found that within hours of drinking beetroot juice, a group of healthy men saw their blood pressure drop by an average of four to five points. The study was published last week in Nutrition Journal.
While that number may seem small, WebMD writes that "on a public health level a reduction like that would equate to a 10% reduction in deaths due to heart disease."
"It's promising that we can see an effect from a single dose," researcher Dr. Leah Coles told WebMD. "That effect might be even greater over the long term if they are drinking it day upon day."
The study involved 15 men and 15 women who drank 17.6 ounces (about 520 mL) of a drink containing about three-fourths beetroot juice and one-fourth apple juice or a placebo drink. Among both men and women, blood pressure levels dropped six hours after drinking the beet juice. But it was the men who saw the most significant difference, an average of about 4.7 points among the beetroot juice drinkers.
The study supports another published in March in the British Journal of Nutrition that found that beetroot juice was able to reduce blood pressure in a group of 18 male participants as soon as three hours after consumption.
While beetroots contain heart-healthy compounds like vitamins C and K, fiber and polyphenols, scientists say it's the high nitrate content that's likely responsible for the ability to reduce blood pressure.

High Blood Pressure Prevention Vocabulary
blood pressure - ความดันโลหิต (See Wikipedia)
high blood pressure - ความดันโลหิตสูง Same as "hypertension" below
hypertension - a long-term medical condition in which the blood pressure in the arteries is very high, this requires the heart to work harder than normal to circulate blood through the blood vessels which can lead to heart disease, "hypertension is a major risk factor for stroke, myocardial infarction (heart attacks), heart failure, aneurysms of the arteries (e.g. aortic aneurysm), peripheral arterial disease and is a cause of chronic kidney disease. Even moderate elevation of arterial blood pressure is associated with a shortened life expectancy. Dietary and lifestyle changes can improve blood pressure control and decrease the risk of associated health complications, although drug treatment is often necessary in people for whom lifestyle changes prove ineffective or insufficient" (See Wikipedia)
beetroot - a deep red vegetable that is a "rich source of potent antioxidants and nutrients, including magnesium, sodium, potassium and vitamin C, and betaine, which is important for cardiovascular health" หัวบีตรูตใช้เป็นอาหารสัตว์ (See Wikipedia)
juice - น้ำผลไม้ผัก
drinking a glass of beetroot juice

nitrate - "Research published in the American Heart Association journal Hypertension showed drinking 500 ml of beetroot juice led to a reduction in blood pressure within one hour. The reduction was more pronounced after three to four hours, and was measurable up to 24 hours after drinking the juice. The effect is attributed to the high nitrate content of the beetroot. The study correlated high nitrate concentrations in the blood following ingestion of the beetroot juice and the drop in blood pressure. Dietary nitrate, such as that found in the beetroot, is thought to be a source for the biological messenger nitric oxide, which is used by the endothelium to signal smooth muscle, triggering it to relax. This induces vasodilation and increased blood flow" (See Wikipedia & effect of nitrate)
