Celery

Studies in people

• Benefit

  Blood pressure and blood sugar³

  In people, celery lowered blood pressure, fasting blood sugar and triglycerides, but scientists say more good trials are needed.

• Concern

  Severe allergic reactions⁴

  Some people allergic to celery can have severe reactions throughout the body, and current tests may miss this.

• Open question

  Food allergy in older people⁵

  In older people with celery allergy, celery that was properly digested was less able to trigger allergy reactions.

Study type not stated

• Open question

  Chemical levels in plant parts⁶

  In celery, PAE levels were higher in leaves than stems and in greenhouse crops, but risks from eating it were acceptable.

• Open question

  Pesticide residues in vegetables⁷

  More than half of celery samples had pesticide residues, and most stayed below the maximum residue limit.

• Concern

  Heavy metals in food⁸

  Celery grown in polluted soil soaks up cadmium, and eating it often may put your health at risk.

How it’s made and used

• Pesticide residue in vegetables⁹

  In celery, metconazole broke down differently than in other vegetables, and the amounts people eat are within acceptable limits.

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 two findings in people. Findings whose study type is not stated are shown but not counted.
