The Claim
Six weeks of daily dietary nitrate intake reduces aortic pulse wave velocity by 0.22 m/s in hypercholesterolemic adults compared to placebo, indicating reduced arterial stiffness, though the difference was not statistically significant (P=0.06).
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.
In adults with high cholesterol, taking dietary nitrate daily for six weeks lowered a measure of arterial stiffness by 0.22 meters per second compared to a placebo, but the change was not statistically significant.
See the scientific wording
Six weeks of daily dietary nitrate intake improves aortic pulse wave velocity by 0.22 m/s in hypercholesterolemic adults, indicating reduced arterial stiffness, though this effect did not reach statistical significance compared to placebo (P=0.06).
When someone eats nitrate-rich food, bacteria in the mouth turn it into nitrite, which enters the blood and becomes nitric oxide. This gas relaxes the walls of the main artery, making it less stiff and allowing blood to flow more easily.
What the research says
1 studyThis study found that drinking beetroot juice daily for six weeks slightly softened the main artery in people with high cholesterol, which is good for heart health — but the change was small and not quite strong enough to say for sure it wasn’t just luck.
