The Claim

A daily intake of approximately 180 grams of high-nitrate vegetables for one week reduces systolic blood pressure by an average of 4 mmHg in healthy young women.

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

Cause and effect
1 study reviewed
In plain English

Eating about 180 grams of high-nitrate vegetables every day for one week lowers systolic blood pressure by an average of 4 mmHg in healthy young women.

See the scientific wording

A daily intake of approximately 180 grams of high-nitrate vegetables for one week reduces systolic blood pressure by an average of 4 mmHg in healthy young women, suggesting dietary nitrate may contribute to acute blood pressure modulation.

Why this might work

Eating nitrate-rich vegetables sends nitrate into the blood, which the mouth bacteria turn into nitrite. The body absorbs that nitrite, and in areas with low oxygen, it becomes nitric oxide. Nitric oxide tells blood vessels to relax, which lowers blood pressure.

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

    This study found that when healthy young women ate lots of nitrate-rich veggies like spinach for a week, their blood pressure dropped by about 4 points — just like the claim says. It proves these veggies can have a quick, measurable effect on blood pressure.
