More Accurate Statement

“Beetroot juice consumption is associated with increased salivary flow in all participants, with healthy individuals showing a greater increase (115.33 ± 119.27 μl/min) compared to periodontitis patients before (101.57 ± 157.27 μl/min) and after treatment (108.66 ± 242.54 μl/min).”

Similar Assertions

People with gum disease have more nitrate left in their saliva after drinking beetroot juice, meaning their mouth bacteria aren't converting it as well as healthy people's bacteria.

83%

People with gum disease don't get the same blood pressure-lowering effect from beetroot juice as healthy people do.

76%

Treating gum disease helps people with gum problems get the blood pressure-lowering benefits from beetroot juice.
