Fibre is one of the most talked-about nutrients in digestive health yet most people still aren’t getting enough of it.
If you’ve ever wondered what fibre actually does, why it matters for your gut, or how much you should be eating each day, this guide breaks it down clearly and simply.
What Is Fibre?
Fibre is a type of carbohydrate found in plant-based foods that the body cannot fully digest. Unlike other carbohydrates that are broken down and absorbed for energy, fibre passes through the small intestine largely intact before reaching the large intestine.
Here, it plays a powerful role. Some types of fibre are fermented by beneficial gut bacteria, while others help add bulk to stool and keep digestion moving smoothly. Together, they support a healthy digestive system and contribute to overall wellbeing.
A diet rich in fibre has been associated with long-term health benefits, including improved heart health, better blood sugar balance and reduced risk of certain chronic conditions.
The Two Types of Fibre - And Why Both Matter.
Fibre isn’t just one thing. There are two main types: soluble fibre and insoluble fibre. Rather than competing, they work together to support different aspects of digestion and health.
Soluble Fibre
Soluble fibre dissolves in water and forms a gel-like substance in the digestive tract. This gel slows down digestion, which can help stabilise blood sugar levels and support normal cholesterol balance. It also helps you feel fuller for longer, which can assist with appetite control and energy stability throughout the day.
You’ll find soluble fibre in foods such as oats, apples, berries, citrus fruits, beans, lentils and certain seeds.
Some soluble fibres also act as prebiotics. This means they feed beneficial bacteria in the gut, helping to support a diverse and balanced microbiome.
Insoluble Fibre
Insoluble fibre does not dissolve in water. Instead, it adds bulk to stool and helps food pass more efficiently through the digestive system. This is especially important for maintaining bowel regularity and preventing constipation.
Wholegrains, vegetables (particularly when eaten with the skin on), nuts and seeds are all good sources of insoluble fibre. For optimal digestive health, your body benefits from a balance of both types.
Fibre and Your Gut Microbiome
Your gut microbiome is made up of trillions of microorganisms that live in your digestive tract. These bacteria play a vital role in digestion, immunity and nutrient production.
Certain fibres particularly prebiotic fibres act as fuel for these beneficial bacteria. When fermented, they produce compounds known as short-chain fatty acids, which help support gut lining integrity, reduce inflammation and maintain digestive balance. In simple terms, fibre helps feed the good bacteria that help keep you well.
Signs You May Not Be Getting Enough Fibre
If your diet is low in fibre, you may notice symptoms such as sluggish digestion, bloating, constipation or feeling hungry soon after meals. Some people also experience energy dips or irregular bowel movements.
Increasing fibre intake gradually can often help improve these issues but it’s important to do so slowly and ensure adequate hydration at the same time.
How to Increase Fibre Safely
When increasing fibre, gradual change is key. A sudden jump in intake can lead to bloating or digestive discomfort.Focus on incorporating more whole plant foods into your meals, including wholegrains, beans, lentils, vegetables, fruits, nuts and seeds. Drinking enough water throughout the day is equally important, as fibre works best when the digestive system is properly hydrated.
Fibre and Everyday Wellness
Fibre supports far more than digestion alone. It contributes to gut health, balanced energy, appetite control and heart health.
