Dietary fibre is one of the most overlooked nutrients in modern diets, yet it plays a critical role in maintaining long-term health. Despite clear guidance and growing awareness, most people in the UK still fall far short of recommended daily fibre intake. At Grounds for Good, we believe that part of the solution may already be sitting in your kitchen — in the form of used coffee grounds.
What Is Dietary Fibre and Why Does It Matter?
Dietary fibre refers to plant-based carbohydrates that the body cannot fully digest. Unlike other nutrients, fibre passes relatively intact through the digestive system, delivering a range of powerful health benefits along the way.
There are two main types of fibre:
- Soluble fibre – dissolves in water and helps regulate blood sugar and cholesterol levels
- Insoluble fibre – adds bulk to stool and supports healthy digestion
Both are essential for a well-functioning body.
Fibre: Nature’s Own “Ozempic”
Fibre is increasingly being described as nature’s own version of Ozempic.
By slowing digestion, stabilising blood sugar, and increasing satiety, fibre naturally helps regulate appetite and reduce overeating. It supports:
- Reduced hunger and snacking
- Better weight management
- Improved metabolic health
Unlike pharmaceutical solutions, fibre works as part of everyday food — making it one of the most accessible and powerful tools for improving public health.
Key Health Benefits of Fibre
A fibre-rich diet is associated with:
- Improved digestive health
- Heart health and lower cholesterol
- Better blood sugar control
- Sustained energy and fullness
- Reduced risk of chronic diseases
In short, fibre isn’t just beneficial — it’s essential.
The Fibre Gap in the UK
Despite these benefits, the UK faces a significant fibre shortfall.
- Recommended intake: 30g per day
- Average intake: ~18g per day
That’s a gap of around 40%.
Why Aren’t We Eating Enough Fibre?
- Highly processed diets lacking natural fibre
- Low fruit and vegetable intake
- Lack of awareness around fibre importance
- Convenience-driven eating habits
The result: a population under-consuming one of the most important nutrients for long-term health.
A Surprising Solution: Used Coffee Grounds
What if the answer to the UK’s fibre gap wasn’t growing more — but wasting less?
Used coffee grounds are typically discarded, yet they are incredibly rich in dietary fibre.
Just How Much Fibre?
- Waste coffee grounds: ~54g fibre per 100g
Compared to other high-fibre foods:
- Chia seeds: ~34g per 100g
- Oats: ~10g per 100g
- Lentils (cooked): ~8g per 100g
- Whole wheat bread: ~6–7g per 100g
This makes coffee grounds one of the most fibre-dense resources available — yet almost entirely overlooked.
A True Circular Economy Approach
In a true circular economy, we prioritise using what already exists.
Growing new crops specifically for fibre comes with:
- Economic costs (land, labour, transport)
- Environmental impact (water use, fertilisers, emissions)
- Climate risk (crop yields affected by extreme weather)
By contrast, coffee grounds are already produced at scale. Repurposing them creates a low-impact, climate-resilient fibre source without additional agricultural demand.
From Waste to Wellness
Incorporating recycled coffee grounds into food products offers a powerful dual benefit:
- Boosting fibre intake across the population
- Reducing food waste and supporting sustainability
With the right processing, they can be used in baked goods, snacks, and functional foods — helping people increase fibre intake without changing habits drastically.
The Bigger Picture
Closing the UK’s fibre gap will take more than education — it will require innovation.
While whole foods remain essential, sustainable alternatives like repurposed coffee grounds offer a scalable way to bridge the gap.
Final Thoughts
Dietary fibre is one of the simplest ways to improve health outcomes, yet it remains chronically under-consumed. By rethinking waste and embracing circular solutions, we can tackle both nutrition and sustainability challenges at once.
At Grounds for Good, we’re working to turn everyday waste into a meaningful health solution — one cup of coffee at a time.
Sign up to our newsletter at www.groundsforgood.co.uk to follow our journey and see how we’re transforming waste coffee grounds into a sustainable, high-fibre ingredient for the future.
