Similar Assertions

People with more oral bacteria that convert nitrates to nitrites tend to have lower blood sugar levels.

88%

People with more oral bacteria that convert nitrates to nitrites tend to have better insulin sensitivity, meaning their bodies handle sugar better.

83%

Even after accounting for many other factors that could affect insulin sensitivity, the link between oral bacteria that convert nitrates to nitrites and better insulin sensitivity still holds true.

81%

People with more oral bacteria that convert nitrates to nitrites tend to have lower blood pressure, but only if they don't already have high blood pressure.

79%

The small blood pressure increase from using the special mouthwash was similar in size to what's known to increase the risk of heart disease and stroke.
