Radish

Studies in people

• Concern

  Blood pressure and blood vessels²

  In people with metabolic syndrome, Sakurajima radish raised systolic blood pressure and a stress marker, without improving blood vessel function.

Animal and lab studies only

• Benefit

  Antioxidant response in cells⁶

  In lab studies, radish sprouts triggered more antioxidant activity in cells than the same radishes' mature roots did.

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.

• Nitrates in vegetables³

  Radish and cabbage nitrates were measured in Poland and did not pose a health risk to consumers.

• Residue levels on leaves⁴

  In field tests, chlorfenapyr left more residue on radish leaves than on the radish itself.

• Heavy metals in root vegetables⁵

  Radish heads and shells held the most heavy metals, while the inner parts had less.

• Cooking lowers arsenic absorption⁷

  Boiling radish lowered how much arsenic the body absorbs from it compared with raw, steamed or griddled radish.

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.
