The Fibre Gap  —  and How to Close It

What is the Fibre Gap?

The fibre gap is the growing difference between how much fibre our bodies need and how much we actually consume each day.

Most adults should be getting 25–38g of fibre daily, yet many people fall well short of this target. Modern diets—heavy in refined grains and ultra-processed foods—deliver plenty of calories, but very little fibre.

This gap may seem invisible, but its effects are felt every day.

Why the Fibre Gap Matters

Fibre is essential fuel for your gut. When intake is low:

  • Gut bacteria are under-fed, leading to imbalance
  • Digestive comfort suffers (bloating, irregularity)
  • Blood sugar and cholesterol control weaken
  • Satiety drops, making it easier to overeat
  • Long-term health risks rise, driven by chronic low-grade inflammation

In short, the fibre gap quietly undermines gut health—and when the gut struggles, the rest of the body follows.

Why It’s Hard to Get Enough Fibre from Food Alone

Even with good intentions, many people find it challenging to meet fibre needs consistently:

  • Busy lifestyles limit whole-food meals
  • Some high-fibre foods feel harsh on sensitive guts
  • Sudden increases in fibre can cause discomfort

That’s why not all fibres are equal, and why how you close the fibre gap matters.

A Smarter Way to Close the Fibre Gap

1. Prioritise Gentle, Functional Fibre

Look for soluble, fermentable fibres that nourish the gut without irritation. One of the most researched is beta-glucan, a naturally occurring compound found in barley.


Beta-glucan:

  • Forms a gentle gel in the gut
  • Is slowly fermented by beneficial bacteria
  • Supports the production of short-chain fatty acids that strengthen the gut lining
  • Helps improve stool regularity, cholesterol balance, and blood sugar response

This makes it especially suitable for daily, long-term gut support.

2. Build Fibre Consistently (Not Suddenly)

Closing the fibre gap works best when fibre intake is:


  • Steady (every day, not once in a while)
  • Well-tolerated, so your gut can adapt
  • Easy to maintain, even on busy days

Consistency matters more than extremes.

3.  Combine Whole Foods with Targeted Supplementation

Whole foods should always form the foundation—vegetables, whole grains, legumes, and fruits.

But when diet alone isn’t enough, targeted fibre supplementation can reliably

help bridge the gap.


This is where Gutrient comes in.
