These factors worsened in the placebo group. The subjects also had a slight decrease in blood clotting, another sign of improved cardiovascular health. Using ultrasound, researchers determined that the nitrate-rich beetroot juice led to a 24 percent improvement in blood vessel flexibility and tone. All of the subjects had elevated cholesterol levels. All three techniques found a reduction in blood pressure among people drinking the beetroot juice with naturally occurring nitrate.Ī separate study by the same researchers involved giving 69 patients a cup of either nitrate-rich beetroot juice or beetroot juice without nitrate daily for six weeks. The researchers measured the subjects’ blood pressure using three different techniques. The drinks were switched so that everyone in the study eventually consumed both types of juice daily for two weeks. Researchers at Queen Mary University in London asked 68 people with hypertension to drink either 1 cup (150 mL) of nitrate-rich beetroot juice or nitrate-free beetroot juice daily. The studies on the benefits of beetroot juice and hypertension show remarkably consistent benefits. (The juice is extracted from the red beetroots you cook with or use in salads, not the sugar beets used for making sucrose.) How to Lower Blood Pressure with Beetroot Juice But the hands-down richest source is beetroot and, in particular, beetroot juice and concentrate. Many fruits and vegetables are good sources of nitrate, and there are significant amounts of nitrate in celery, lettuce, arugula, and spinach. Through a series of steps, the body converts nitrate to nitric oxide. Nitric oxide’s nutritional precursors include the amino acid L-arginine, but dietary nitrate is also an often overlooked and excellent precursor. Because of this property, nitric oxide plays a key role in maintaining normal blood pressure. Nitric oxide helps the body’s cells talk with each other, and one of its functions is to tell the endothelial cells that line blood vessels to dilate or relax. The journal Science once declared nitric oxide to be the “molecule of the year,” and three scientists earned the Nobel Prize in Physiology or Medicine for their research on this substance. The story of dietary nitrate begins with nitric oxide, not to be confused with nitrous oxide-aka laughing gas. Nitrate is now coming out of obscurity, with studies showing it can help to lower blood pressure, protect against glaucoma, improve athletic performance, and more. Only recently has nitrate-and supplements containing it in the form of beetroot-gained serious scientific interest. If you’ve never heard of “dietary nitrate,” you’re far from alone. The secret to the healing powers of the humble beetroot? Turns out, it’s an incredibly concentrated source of dietary nitrate. Heading out the door?
