The Claim
Cruciferous vegetables supply sulforaphane, which activates cellular antioxidant defense pathways.
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.
Cruciferous vegetables contain sulforaphane, and sulforaphane triggers the activation of cellular pathways that defend against oxidative stress.
See the scientific wording
Cruciferous vegetables provide sulforaphane, which activates cellular antioxidant defense pathways.
Sulforaphane enters cells and binds to a protein that normally blocks a master regulator of defense genes. This binding frees the regulator, allowing it to move into the cell's control center and turn on genes that make enzymes to neutralize harmful chemicals and repair damaged molecules.
What the research says
3 studiesThis study showed that taking a sulforaphane supplement for a year reduced signs of abnormal cell growth in the lungs of former smokers, which is exactly what sulforaphane is expected to do by turning on the body’s natural defense systems against damage.
Study: Optimal dietary patterns for healthy aging
This study found that people who ate lots of vegetables, including broccoli and cabbage, lived healthier longer lives. Since these veggies contain sulforaphane—which helps cells fight damage—the results support the idea that eating them boosts your body’s natural defenses.
This study shows that a compound in broccoli (sulforaphane) turns on the body’s natural defense system against damage from toxins and stress, which is exactly what the claim says.
