Summary

This study looks at whether adding 10 grams of fibre to your daily diet for two weeks can improve mental wellbeing, including anxiety, stress, sleep, and mood. Researchers will track changes in 40 healthy adults aged 18-40 using questionnaires. It's a small, early-stage trial to see if this simple diet change is worth studying further.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: dietary fibre (10 grams per day)
What this could lead to: If it works, this could point toward a simple dietary change to help ease anxiety, stress, and sleep problems.
What could go wrong: This is a very small, early feasibility trial with only 40 people and no placebo group, so results may not be reliable or apply to everyone.
