When people think about healthy eating, fibre is often associated with keeping digestion regular. While that is certainly one of its benefits, fibre does far more than many people realise.
From feeding the beneficial bacteria in your gut to helping you feel fuller after meals, fibre plays an important part in supporting digestive and metabolic health. Yet despite its importance, most adults in the UK consume far less fibre than recommended.
Let’s take a closer look at why fibre deserves more attention and how increasing your intake could support your everyday wellbeing.
What Is Fibre?
Dietary fibre is a type of carbohydrate found in plant foods. Unlike other carbohydrates, it is not fully broken down or absorbed in the small intestine. Instead, it travels through the digestive system, where it performs several valuable functions.
Soluble Fibre
Soluble fibre dissolves in water to form a gel-like substance. It can be found in foods such as oats, apples, pears, citrus fruits, beans, lentils and barley.
This type of fibre helps slow digestion, which can contribute to feeling satisfied after meals. It also provides food for beneficial gut bacteria.
Insoluble Fibre
Insoluble fibre does not dissolve in water. Instead, it adds bulk to stools and helps food move through the digestive tract more efficiently.
Good sources include wholegrain bread, brown rice, nuts, seeds, vegetables and wheat bran.
Simple tip: most plant foods contain a mixture of both types, making a varied diet the best approach.
Why Fibre Matters for Your Gut
Your digestive system is home to trillions of microorganisms, collectively known as the gut microbiome. These bacteria play an important role in digestion and many other aspects of health.
Many beneficial bacteria rely on certain types of fibre as their food source. These fibres are known as prebiotics.
When gut bacteria ferment prebiotic fibre, they produce compounds called short-chain fatty acids. These compounds help nourish the cells lining the colon and contribute to a healthy digestive environment.
A diet rich in fibre also supports microbial diversity. In general, a more varied microbiome is considered a positive sign of good gut health.
Fibre and Digestive Comfort
Regular fibre intake may support normal digestive function in several ways.
It helps add bulk to stools, encourages regular bowel movements and supports the natural movement of food through the digestive tract.
Increasing fibre too quickly, however, can sometimes lead to temporary bloating or gas. For this reason, it is usually best to increase intake gradually while drinking plenty of water.
Simple changes often work well
- Add an extra portion of vegetables with dinner.
- Include berries with your breakfast.
- Add beans or lentils to soups and stews.
- Choose wholegrain alternatives instead of refined grains.
- Keep nuts or seeds available as a simple snack.
How Fibre Supports Metabolic Health
Digestive health and metabolic health are more closely connected than many people realise.
The gut microbiome influences how the body processes nutrients and interacts with hormones involved in appetite and energy regulation. Researchers continue to investigate how dietary fibre may help support these natural processes.
Foods rich in fibre often take longer to digest than highly processed alternatives. This can help meals feel more satisfying and support steady eating habits throughout the day.
- Wholegrains
- Beans
- Lentils
- Vegetables
- Fruit
- Nuts
- Seeds
Are You Getting Enough Fibre?
The UK recommendation for adults is around 30 grams of fibre each day, but surveys suggest that many people consume considerably less than this.
If your meals regularly include refined carbohydrates, sugary snacks or convenience foods, your fibre intake may be lower than you think.
A simple way to improve intake is to build each meal around plant foods.
- Fruit
- Vegetables
- Wholegrains
- Beans
- Lentils
- Nuts
- Seeds
Lifestyle Habits That Work Alongside Fibre
Fibre works best as part of an overall healthy lifestyle.
To support digestive and metabolic wellbeing, it also helps to:
- Stay well hydrated throughout the day.
- Exercise regularly.
- Eat a wide variety of plant foods.
- Get enough sleep.
- Manage stress where possible.
These everyday habits work together to support normal digestive function and overall health.

Supporting Your Daily Gut Health Routine
Building healthy habits takes time, and consistency matters more than perfection.
Alongside a balanced diet rich in fibre, some people choose to include a gut health supplement as part of their daily routine.
FitLab Nutrition’s Daily Biome combines live cultures, prebiotic fibre, L-glutamine and carefully selected botanicals including ginger, turmeric, marshmallow root and dandelion root. The formula is designed to complement a balanced diet and support everyday digestive wellbeing as part of a healthy lifestyle.
It provides a convenient way to include a range of gut-supporting ingredients within your daily routine.
Explore Daily BiomeThe Bottom Line
Fibre is much more than a nutrient that helps keep you regular.
It supports your gut microbiome, contributes to digestive comfort and forms an important part of a balanced dietary pattern that supports metabolic wellbeing.
The good news is you don’t need to completely change your diet to get more fibre. Making small, steady changes, like eating more whole plant foods and picking fibre-rich meals, can really help over time.
When combined with regular exercise, good sleep and healthy lifestyle habits, fibre remains one of the simplest ways to support both digestive and overall well-being.
