Chard

Studies in people

• Benefit

  Nitrate and blood pressure³

  In people, chard gels raised blood nitrate and nitrite and lowered systolic blood pressure, similar to beetroot juice.

Found in some samples or products

These come from where it was grown, how it was processed or cooked, or what it was made into. They are not about the ingredient itself, so the signal does not count them.

• Arsenic in leafy greens⁴

  Chard grown in arsenic-rich soil and water took up arsenic into its leaves, above the limit set in Argentina.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted.
