The Claim
Consumption of a freeze-dried watercress drink leads to significant increases in mercapturic acid biomarkers regardless of GSTM1 and GSTT1 genotype status, with only minor additional increases observed in double-null individuals.
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.
Drinking a freeze-dried watercress beverage increases mercapturic acid biomarkers in all people, whether or not they have specific genetic variations in GSTM1 and GSTT1 enzymes, with only slightly higher increases in those with both genes missing.
See the scientific wording
The detoxification-enhancing effect of a freeze-dried watercress drink is largely independent of genetic variations in glutathione-S-transferase enzymes (GSTM1 and GSTT1), as significant increases in mercapturic acid biomarkers were observed across all genotype groups, with only minor additional effects in double-null individuals.
A compound in watercress triggers a cellular defense system that boosts the body's ability to bind toxic chemicals to a natural molecule called glutathione, turning them into water-soluble waste that the kidneys flush out in urine, regardless of a person's genetic makeup.
What the research says
1 studyDrinking this watercress drink helped people’s bodies get rid of harmful chemicals from pollution, no matter what genes they had. Even people who normally have trouble detoxifying still saw big improvements.
