Study: Beetroot Juice May Lower Blood Pressure
A study showed that drinking beetroot juice might help lower blood pressure, especially in older people.
The juice contains nitrates, which change the bacteria in your mouth in a good way.
This change reduces bad bacteria and boosts good ones, which helps turn nitrates into something called nitric oxide, which is important for healthy blood vessels.
This process aids in the regulation of blood pressure.
Researchers found that the juice worked better for older adults than younger ones.
Other nitrate-rich foods include spinach and kale.
A study suggests beetroot juice can lower blood pressure, particularly in older adults.
Researchers found that nitrate-rich beetroot juice altered the oral microbiome.
Older adults experienced a decrease in harmful mouth bacteria and an increase in beneficial bacteria after consuming the juice.
Nitrate from the juice helps convert to nitric oxide, crucial for blood vessel function.
The study included adults under 30 and those in their 60s and 70s.
