Drinking specific vegetable juice could reduce the blood pressure of older adults, find the study

Beet juice, which is rich in nitrates, has been linked to changing the community of bacteria living in the mouth.

Now, a new study has found that drinking this juice could reduce the blood pressure of older adults.

Researchers at the University of Exeter compared the response of the younger and older participants with the juice and published the study in Biology and Medicine of Free Radicals.

Thirty -nine participants under 30, plus 36 individuals in their 60s and 70s, were divided into two separate phases of two weeks.

A group consumed beet juice shots in nitrate daily, while the other group, a placebo group, received a version without nitrates. Each group had a “wash period” between phases to restore their systems.

The researchers practiced the sequencing of bacterial genes to identify which microbes were present in the mouth of the participants before and after each treatment.

Older adults who drank beet juice rich in nitrate had less bacteria in the mouth called PREVETELLA, which is linked to inflammation, and more useful bacteria such as Neisseria.

“Foods that are high in dietary nitrates, such as green leafy vegetables, beets and lettuce, can help reduce blood pressure.”

News senior medical analyst, Dr. Marc Siegel, told News Digital that nitrates lead to lower blood pressure by improving flexibility, decreasing resistance in blood vessels and reducing inflammation.

Patients began the study with greater blood pressure, which fell after beet juice, but blood pressure did not change with those of the placebo group.

“We know that foods that are high in dietary nitrates, such as green leafy vegetables, beets and lettuce, can help reduce blood pressure,” Siegel said.

He added: “His body becomes nitrates into nitric oxide. Nitric oxide is a key molecule in vascular health, since it promotes that the vessels dilate and, therefore, reduce blood pressure.”

Co -author Andy Jones, a professor at the University of Exeter, said in a press release that the study shows that “foods rich in nitrate alter oral microbiome in a way that could result in lower inflammation, as well as a decrease in blood pressure in the elderly.”

Lee Beniston, associate director of the Biotechnology and Biological Sciences Research Council, said that “research is a great example of how bioscience can help us better understand the complex links between diet, microbiome and healthy aging.”

“Upon discovering how nitrate in the diet affects oral bacteria and blood pressure in older adults, the study opens new opportunities to improve vascular health through nutrition,” Beniston added.

Both researchers shared that more research is needed.

Siegel pointed out that “as we age, our lower biodisponable nitric oxide levels, so it makes sense that we see more benefits in the consumption of dietary nitrates in older patients.”

He said the study supports the well -established belief that a good diet, high in fresh fruits and vegetables, can help control many chronic medical conditions.
