H. pylori infection and sprout intake
How does broccoli sprout intake affect H. pylori colonization and gastric inflammation measures?
Human and animal · comparative trial of infection measures

Key findings
Reduction in infection and inflammation measures
Test measures reflecting bacterial colonization and gastric inflammation fell in the broccoli sprout group.
Return toward baseline after discontinuation
Two months after intake stopped, related values returned to baseline.
Animal data for the NRF2 mechanism
Mice lacking NRF2 were used as a comparison to examine the defense pathway's role. This was a mechanistic experiment distinct from the human trial.
Study design
Forty-eight infected adults were assigned to 70 g/day of broccoli sprouts or alfalfa control for eight weeks. Urea breath tests, stool antigen, and serum pepsinogen were measured, alongside a separate mouse experiment.
