Posted on November 29, 2018

Prebiotics are essential for good gut health!

Is there a way to incorporate prebiotic foods when following a low FODMAP diet?

Read on to find out!

What are Prebiotics?

Prebiotics are a type of fibre that promotes good gut health by stimulating growth of good bacteria in the large intestine. While not all fibres are prebiotic, all prebiotics are fibre! Prebiotics are classified as:

  1. Fibre that passes through the gastrointestinal tract. In other words, are resistant to gastric acids and do not get digested by enzymes or absorbed by GI tract,
  2. Fibre that is fermented by gut microflora in the large intestine,
  3. Fibre that promotes growth of good bacteria.

The extent of health benefits of prebiotics are still being studied, but there is good evidence to suggest that prebiotics have a positive impact on our overall gut health. Prebiotics may have a protective benefit against cancers such as colon, maintain balance of healthy bacteria, improve absorption of minerals and may have benefits for metabolic diseases such as improved control of blood glucose levels and insulin in those with Type II Diabetes.

Prebiotics and the Low FODMAP diet

Prebiotics are predominately found in foods containing Fructans and Galacto-Oligosacchatrides (GOS), making up the O in FODMAPs. of the four FODMAP groups. People following the low FODMAP diet tend to avoid GOS and Fructan intake, therefore, limit their intake of prebiotic foods.  However, it is still possible to consume prebiotic foods in all three phases of the low FODMAP diet, which are the low FODMAP phase, reintroduction phase and maintenance phase.


It is important to complete the reintroduction and maintenance phase as you may tolerate larger amounts of fructans and GOS. Not only does it allow you to have more variety in your diet, but also help maintain a healthy gut microbiome. Don’t forget to consult a dietitian when starting a low FODMAP diet to ensure you are completing all three phases correctly.

Smaller serves of common high FODMAP foods can also be considered low FODMAP prebiotics.
