Broccoli sprouts: the surprising new hope for gut health?
NCT ID NCT05507931
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether eating steamed broccoli sprouts daily for 28 days could increase anti-inflammatory compounds in the blood and stool of people with mild ulcerative colitis. 23 participants took either 1 or 3 servings of sprouts per day. The goal was to see if this diet is feasible and could reduce inflammation, paving the way for a larger trial.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- broccoli sprouts
- What this could lead to
- If it works, this could point toward a simple dietary addition to help manage mild ulcerative colitis symptoms.
- What could go wrong
- This is a very small pilot study with only 23 people, so results may not apply to everyone. It only tested feasibility and short-term effects, not long-term benefits or risks.
