The Claim

Consuming approximately 180 grams of high-nitrate vegetables daily for one week increases plasma nitrate concentrations by 150% and plasma nitrite concentrations by 90% in healthy young women, demonstrating that dietary nitrate from whole vegetables is effectively absorbed and converted into bioactive nitrite in humans.

How it works
1 study reviewed
In plain English

Eating about 180 grams of high-nitrate vegetables every day for one week raises plasma nitrate levels by 150% and plasma nitrite levels by 90% in healthy young women, showing that nitrate from these vegetables is absorbed and converted to nitrite in the human body.

See the scientific wording

Consuming approximately 180 grams of high-nitrate vegetables daily for one week increases plasma nitrate concentrations by 150% and plasma nitrite concentrations by 90% in healthy young women, demonstrating that dietary nitrate from whole vegetables is effectively absorbed and converted into bioactive nitrite in humans.

Why this might work

When a person eats high-nitrate vegetables, the nitrate is absorbed from the gut into the blood. The blood carries nitrate to the salivary glands, which pump it into the mouth. Bacteria on the tongue turn that nitrate into nitrite. The person swallows the nitrite, which re-enters the blood and raises its levels. This process happens reliably when people eat enough nitrate-rich vegetables for a week.

  1. Study: High-nitrate vegetable diet increases plasma nitrate and nitrite concentrations and reduces blood pressure in healthy women

    Eating about 180 grams of nitrate-rich veggies like spinach and rocket for a week made the blood levels of nitrate and nitrite go up a lot in young women, proving these veggies deliver active compounds into the body.
