The Claim
Daily consumption of a freeze-dried watercress drink containing approximately 40 mg of 2-phenethyl isothiocyanate (PEITC) for two weeks significantly increases urinary detoxification biomarkers of acrylonitrile, crotonaldehyde, methacrolein, methyl vinyl ketone, and propylene oxide by 18.8% to 55.2% in healthy adults.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Healthy adults who drink a freeze-dried watercress beverage containing 40 mg of PEITC daily for two weeks show a measurable increase in urinary biomarkers for five environmental carcinogens, with increases ranging from 18.8% to 55.2%.
See the scientific wording
Daily consumption of a freeze-dried watercress drink containing approximately 40 mg of 2-phenethyl isothiocyanate (PEITC) for two weeks significantly increases urinary detoxification biomarkers of five additional environmental carcinogens—acrylonitrile, crotonaldehyde, methacrolein, methyl vinyl ketone, and propylene oxide—by 18.8% to 55.2% in healthy adults.
A compound in watercress enters the body and triggers a cellular defense system that attaches a natural molecule called glutathione to toxic chemicals from pollution. This makes the toxins water-soluble so the kidneys can filter them out and remove them through urine.
What the research says
1 studyDrinking a special watercress drink every day for two weeks helped people’s bodies flush out five harmful chemicals from pollution through their urine, according to a well-done study.
