The Claim
Acutely lowering salivary pH with sugar-containing gum enhances bacterial reduction of dietary nitrate to nitrite in the oral cavity, leading to increased plasma nitrite concentration and acute blood pressure reduction, independent of changes in salivary nitrate secretion or plasma nitrate levels.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Chewing sugar-containing gum that lowers saliva acidity increases the conversion of dietary nitrate to nitrite by oral bacteria, which raises nitrite levels in the blood and lowers blood pressure shortly after, without altering nitrate levels in saliva or blood.
See the scientific wording
Acutely lowering salivary pH with sugar-containing gum enhances bacterial reduction of dietary nitrate to nitrite in the oral cavity, increasing plasma nitrite concentration and contributing to acute blood pressure reduction, independent of changes in salivary nitrate secretion or plasma nitrate levels.
Chewing sugary gum makes the mouth acidic, which helps mouth bacteria turn nitrate from food into nitrite. This nitrite enters the bloodstream and is converted to nitric oxide, which relaxes blood vessels and lowers blood pressure.
What the research says
1 studyChewing sugary gum makes your mouth more acidic, which helps mouth bacteria turn nitrate from beetroot juice into nitrite. This nitrite gets into your blood and briefly lowers your blood pressure—even though the amount of nitrate in your saliva doesn’t change.
