Mango a day keeps the doctor away? new study tests immune and brain benefits
NCT ID NCT06229262
First seen Jun 24, 2026 · Last updated Jul 10, 2026 · Updated 2 times
Summary
This study will test whether eating 1.5 cups of mango every day for 12 weeks can improve immune function and thinking skills in healthy young adults aged 18 to 30. Researchers will measure changes in immune cells, inflammation, and cognitive test scores. The goal is to see if this simple dietary addition can support overall health.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

- What this could lead to
- If it works, this could show that a simple dietary change like eating mango can boost immune health and cognitive performance in young adults.
- What could go wrong
- This is a small, early-stage trial with only 54 participants, so results may not apply to everyone. The effects may be modest or not statistically significant.
