Study: Beetroot Juice May Lower Blood Pressure in Elderly
A study found that drinking beetroot juice might help older people with high blood pressure.
The juice contains nitrate, which affects the bacteria in your mouth.
In the study, older adults drank beetroot juice for two weeks, and their blood pressure went down.
This is because the good bacteria in their mouths increased, while the harmful bacteria decreased.
This process helps the blood vessels work better, which then helps with blood pressure.
You can also get nitrates from other vegetables like spinach and kale, if you don't like beetroot.
Study suggests beetroot juice may lower blood pressure in older adults.
The effect is linked to changes in the oral microbiome, according to researchers.
Older adults experienced a decrease in harmful mouth bacteria and an increase in beneficial bacteria.
Nitrate-rich beetroot juice was administered twice daily for two weeks in the study.
Nitrate is important for blood vessel function and blood pressure regulation.
