Broccoli's hidden messages: can plant molecules talk to our cells?
NCT ID NCT07456267
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether small molecules called microRNAs from broccoli can be absorbed into the blood and affect gut bacteria in 20 healthy adults. Participants ate broccoli, and researchers measured these plant molecules in blood and stool samples. The goal was to understand a possible 'cross-kingdom' communication, not to treat any disease.
