a common vegetable found to be deficient in blood pressure In old people, a new Study Gives suggestions.
Beetroot Juice may reduce blood pressure in people 60 and older by suppressing potentially harmful bacteria In the mouth.
expert of University of Exeter The responses of young adults and older adults were compared to beetroot juice, which is rich in dietary nitrate.
These nitrates are converted by the body into nitric oxide, which helps to relax and widen blood vessels and reduce blood pressure.
The study included 39 adults under the age of 30 and 36 people between the ages of 60 and 70.
For two weeks, each group was given shots of beetroot juice.
After a two-week break, during which people were given antiseptic mouthwash every day, the groups were then given placebo juice with the nitrates removed for a fortnight.
The researchers used gene sequencing to analyze the bacteria present in the mouth after each part of the test.
In both groups, the so-called oral microbiome The complex ecosystem of microorganisms in the mouth changed after drinking nitrate-rich juice, although the effects varied.
In older people, there was a decline in normal bacteria that can sometimes cause infections, and an increase in bacteria that may benefit health.
The researchers also found that the older group’s blood pressure was reduced after drinking nitrate-rich juice for two weeks.
Professor Andy Jones, of the University of Exeter, said: “This study shows that nitrate-rich foods alter the oral microbiome in a way that may result in reduced SwellingAs well as reduction in blood pressure in older people.
“This paves the way for larger studies to explore the impact of lifestyle factors and biological sex on how people respond to dietary nitrate supplementation.”
Professor Anne Vanhatalo, from the University of Exeter, said: “We know that a nitrate-rich diet has health benefits, and older people produce less of their own nitric oxide as they age.
“They also have high blood pressure, which may be linked to cardiovascular complications heart attack And trauma.
“Encouraging older adults to consume more nitrate-rich vegetables could have important long-term health benefits.
“The good news is that if you don’t like beetroot, there are many nitrate-rich alternatives such as spinach, rocket, fennel, celery and kale.”
The study, published in the journal Free Radical Biology and Medicine, was funded by a BBSRC Industrial Partnership Award.
Dr Lee Beniston, Associate Director of Industry Partnerships and Collaborative Research and Development at the BBSRC, said: “This research is a great example of how bioscience can help us better understand the complex relationships between diet, the microbiome and healthy ageing.
“By highlighting how dietary nitrate affects oral bacteria and blood pressure in older adults, the study opens new opportunities for improving vascular health through nutrition.”
