Beet the pressure: Regular intake of nitrate-rich juice can lower blood pressure, suggests British meta-analysis
Hypertension, a condition marked by high blood pressure or arterial pressure of 140/90 mm Hg or more, poses significant health risks. It's a major contributing factor to numerous cardiovascular diseases.

It's estimated that hypertension affects 32% of Polish adults below the age of 80. Genetic predispositions, obesity, high salt intake, improper diet, stress, sedentary lifestyle, and deficiencies in certain vitamins (folic acid, riboflavin, and vitamins C and D) contribute to this condition.
Link between nitrates in beet juice and hypertension
Studies housed in the British National Medical Library reveal that beet juice, due to its nitrate content, can aid in decreasing arterial pressure.
Nitrates are integral to the body's nitrogen oxide metabolism, which is essential for properly functioning the blood vessels' endothelium, contributing notably to vasodilation among other things.
The meta-analysis regarding the impact of beet juice supplementation on blood pressure confirmed the effectiveness of this approach. Consumption of beet juice over 2-56 days lowered systolic blood pressure by an average of 3.55 mmHg and diastolic blood pressure by 1.32 mmHg. Further, this effect was seen in hypertensive patients and those with normal pressure.
This is a significant finding from a public health perspective, as even a slight decrease in blood pressure can profoundly reduce the risk of cardiovascular complications. For instance, a blood pressure reduction of just 2 mmHg could result in a 7% reduction in death risk from ischemic heart disease and a 10% reduction in stroke risk.
Additional benefits of beets
While nitrates are the key beet juice component influencing hypertension, beets also carry bioactive compounds with potential health benefits. Betalains, flavonoids, and polyphenols in beets possess antioxidant and anti-inflammatory properties. These may impact endothelial function and arterial pressure in ways different from nitrates.
Inspiring research conclusions indicate that adding beet juice to a daily diet could benefit cardiovascular health. As with all dietary shifts, it's essential to consider personal dietary needs and consult your doctor before making significant changes to your eating habits.
