Gut Health & Microbiome - IBS & symptoms

The low-FODMAP diet, properly used

Last reviewed 3 August 2026. How we write this.

A low-FODMAP diet is a short structured intervention for selected IBS symptoms, not a lifelong template for gut health.

It reduces fermentable carbohydrates, then reintroduces groups to identify tolerance.

The three phases matter

Restriction for a limited period.
Systematic reintroduction.
Personalisation with the broadest tolerated diet.
Dietitian support where possible.

Long-term unnecessary restriction can reduce diet quality and social flexibility.
