The Claim

Chewing sugar-containing acidic gum for 6 hours after consuming 400 mg of dietary nitrate from beetroot juice acutely lowers salivary pH by 1.4 units, increases salivary nitrite production by 45%, raises plasma nitrite concentration by 25%, and reduces systolic and diastolic blood pressure by 2.7 mmHg and 1.9 mmHg, respectively, in healthy young adults.

Source: Lowering salivary pH with sugar-containing gum augments salivary nitrite production and blood pressure reduction with dietary nitrate (beetroot juice).

How it works
1 study reviewed
In plain English

After consuming 400 mg of nitrate from beetroot juice, chewing sugar-containing acidic gum for 6 hours lowers salivary pH by 1.4 units, increases salivary nitrite by 45%, raises plasma nitrite by 25%, and reduces systolic blood pressure by 2.7 mmHg and diastolic blood pressure by 1.9 mmHg in healthy young adults.

See the scientific wording

Chewing sugar-containing acidic gum for 6 hours after consuming 400 mg of dietary nitrate from beetroot juice acutely lowers salivary pH by 1.4 units, increases salivary nitrite production by 45%, raises plasma nitrite concentration by 25%, and reduces systolic and diastolic blood pressure by 2.7 mmHg and 1.9 mmHg, respectively, in healthy young adults, demonstrating a mechanistic link between oral pH modulation and nitrate bioactivation.

Why this might work

Chewing sugary gum makes the mouth acidic, which helps mouth bacteria turn nitrate from food into nitrite. The nitrite gets swallowed, absorbed into the blood, and turns into nitric oxide, which relaxes blood vessels and lowers blood pressure.

What the research says

1 study

  1. Study: Lowering salivary pH with sugar-containing gum augments salivary nitrite production and blood pressure reduction with dietary nitrate (beetroot juice).

    Chewing sugary gum after drinking beetroot juice makes the mouth more acidic, which helps mouth bacteria turn nitrate into nitrite more efficiently. This leads to more nitrite in the blood, which slightly lowers blood pressure.
