Summary

This study looks at how different types of dietary fibre (cellulose, oat fibre, and rye fibre) affect gastrointestinal symptoms like bloating and gas in healthy adults. Researchers will examine how each person's unique gut microbiome influences their reaction to these fibres. The goal is to understand why some people experience discomfort with certain fibres, paving the way for personalised nutrition advice.

What this could mean

What this could lead to: If successful, this could help personalise dietary fibre recommendations to minimise gut discomfort.
What could go wrong: This is a small, early-stage study (28 participants) focused on short-term effects, so results may not apply broadly or lead to immediate dietary advice.
