The Claim
A one-week avoidance of high-nitrate vegetables has no significant effect on plasma nitrate concentrations, plasma nitrite concentrations, or systolic blood pressure in healthy young women.
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.
When healthy young women stop eating high-nitrate vegetables for one week, their blood nitrate levels, nitrite levels, and blood pressure do not change.
See the scientific wording
Avoiding high-nitrate vegetables for one week does not significantly alter plasma nitrate, plasma nitrite, or systolic blood pressure in healthy young women, indicating that the observed effects are specifically linked to nitrate intake rather than general dietary changes.
When you eat vegetables high in nitrate, your body absorbs the nitrate into your blood, sends it to your saliva, where bacteria in your mouth turn it into nitrite. You swallow that nitrite, it re-enters your blood, and in areas with low oxygen, it becomes nitric oxide. Nitric oxide relaxes blood vessels, making them wider and lowering blood pressure. If you stop eating those vegetables for a week, none of this happens — nitrate, nitrite, and blood pressure stay the same.
What the research says
1 studyWhen young women stopped eating nitrate-rich veggies like spinach for a week, their blood nitrate levels and blood pressure didn’t change — but when they ate those veggies, both improved. This shows it’s the nitrate in the veggies, not just eating more vegetables in general, that makes the difference.
