Eating foods with nitrate and nitrite, like leafy greens and cured meats, might help lower blood pressure, protect your heart when blood flow is interrupted, improve blood vessel function, prevent blood clots, help your cells make energy better, and improve signs of metabolic syndrome—even when your body doesn’t have enough oxygen.
Claim Language
Language Strength
probability
Uses probability language (may, likely, can)
The claim uses 'can decrease', 'protect', 'enhance', 'inhibit', 'modulate', 'improve', and 'may serve'—all of which indicate possibility or potential rather than certainty. 'May serve' explicitly signals uncertainty, while the other verbs are modal and non-definitive, fitting the 'probability' category.

Mechanisms of the protective effects of nitrate and nitrite in cardiovascular and metabolic diseases.
This study says that eating foods with nitrate and nitrite (like leafy greens and cured meats) helps your body make a helpful molecule called nitric oxide, even when there’s not enough oxygen — and that this can lower blood pressure and protect your heart and metabolism, just like the claim says.
