The Claim

Daily consumption of a freeze-dried watercress drink providing approximately 40 mg of 2-phenethyl isothiocyanate (PEITC) for two weeks increases urinary excretion of mercapturic acid detoxification products of acrolein by 65.6% and benzene by 37.3% in healthy adults, indicating enhanced detoxification of these environmental carcinogens through the glutathione-S-transferase pathway.

In plain English

Drinking a freeze-dried watercress beverage containing 40 mg of PEITC daily for two weeks increases the amount of specific detoxification byproducts in urine by 65.6% for acrolein and 37.3% for benzene in healthy adults.

See the scientific wording

Consuming a freeze-dried watercress drink providing approximately 40 mg of 2-phenethyl isothiocyanate (PEITC) daily for two weeks significantly increases urinary excretion of mercapturic acid detoxification products of acrolein by 65.6% and benzene by 37.3% in healthy adults, indicating enhanced detoxification of these environmental carcinogens through the glutathione-S-transferase pathway.

Why this might work

A compound in watercress enters the body and changes a protein that normally holds back a master switch for detox genes. This switch turns on and tells cells to make more enzymes that attach a protective molecule to toxic chemicals from smoke and pollution. These tagged toxins are then shipped out of the body in urine.

  1. Study: A watercress drink increases detoxification of common environmental carcinogens such as acrolein and benzene: Results of a randomized clinical trial

    Drinking a special watercress drink every day for two weeks helped people’s bodies flush out harmful chemicals from pollution and smoke more effectively, as shown by higher levels of these toxins in their urine.
