Why Increasing Fibre Matters — The Latest Research & Practical Tips
In the UK, many adults fall short of recommended fibre intake. Despite growing awareness of its importance, most diets still lack sufficient plant-based sources. Fibre isn’t just a buzzword — it plays several essential roles in maintaining everyday well-being.
This article looks at what recent research says about fibre, how much you need, and practical ways to include more in your diet while staying mindful of healthy, balanced eating.
What Does “Dietary Fibre” Actually Mean?
Dietary fibre refers to plant-derived carbohydrates that are not digested in the small intestine. These include naturally occurring components such as:
- Cellulose
- Pectin
- Hemicellulose
- Lignin
- Gums
These fibres can be broadly grouped into:
- Soluble fibre: dissolves in water and forms a gel-like material
- Insoluble fibre: adds bulk to stools and helps maintain regular digestion
Both types contribute to a healthy, varied and balanced diet and are found in many whole foods.
UK Fibre Recommendations
Public health guidance in the UK suggests adults aim for 30g of dietary fibre per day. This target is based on evidence showing that fibre supports normal digestive function and contributes to overall health when consumed as part of a balanced diet.
Despite these recommendations, surveys suggest most adults do not regularly achieve this level. Increasing fibre intake is a simple nutritional step that can be incorporated gradually.
What Recent Research Shows
Recent studies continue to highlight important benefits associated with higher fibre intakes:
Regularity and Digestive Comfort
Fibre contributes to an increase in faecal bulk, especially insoluble fibre, which supports normal bowel function when consumed in sufficient amounts. This effect is one of the reasons fibre is emphasised in dietary guidelines.
Research also shows that a mix of soluble and insoluble fibres supports comfortable everyday digestive rhythm.
Variety Matters
Different types of plant-based foods provide different fibre profiles. A broad mix of fruits, vegetables, pulses, nuts, seeds and whole grains introduces a range of fibre types, helping support digestive health and satiety.
Diverse sources include:
- Oats, barley and wholegrain cereals
- Beans, lentils and peas
- Apples, berries and pears
- Root vegetables and leafy greens
- Nuts, seeds and dried fruit
Fermentation and Gut Environment
Some soluble fibres are fermented by beneficial bacteria in the large intestine. This fermentation supports a healthy gut environment and can contribute to sensations of wellbeing after meals.
Practical Ways to Increase Fibre Intake
Here are practical strategies that fit into everyday life:
-
Start the day with wholegrains
Choose whole-grain cereals, porridge or seeded toast. -
Add vegetables to every meal
Aim for a colourful plate — the more variety, the wider the range of fibre types. -
Snack on plant foods
Fruit, raw vegetables, nuts and seeds are quick, fibre-rich options. -
Include pulses regularly
Try beans or lentils in soups, salads, stews and pasta dishes. -
Stay hydrated
As fibre intake increases, adequate water helps it move smoothly through the digestive system.
Supplements as a Supporting Option
For some people, a fibre supplement can help fill the gap when dietary changes alone are not enough. A multi-fibre dietary supplement such as the Hale&Well Dietary Fibre Complex provides a blend of soluble and insoluble fibres including psyllium, pectin and sugar beet fibre to complement everyday intake.
Supplements should be used alongside a varied diet rich in whole plant foods. They are not a substitute for balanced eating but can be a useful tool for those looking to reach the recommended 30g per day.
Tips for Adding Fibre Gradually
A sudden large increase in fibre may cause mild bloating or gas in some people. A sensible approach is to increase fibre intake gradually over a week, allowing your body to adapt.
Final Thought: Variety + Balance = Best Results
Health authorities emphasise that high fibre intake should come from a diverse mix of foods. Recent research supports the idea that a diet rich in a range of plant foods contributes to everyday wellbeing, digestive regularity and satisfaction after meals.
Whether through food choices or thoughtful supplementation, prioritising fibre is a simple step towards supporting a healthy, balanced lifestyle.
