Introduction
Fibre is one of the most important nutrients for good health, yet many people don’t consume enough of it.
Unlike carbohydrates, protein and fat, fibre isn’t digested or absorbed by the body in the same way. Instead, it passes through the digestive system, where it plays several important roles in supporting digestive health, heart health and overall wellbeing.
Because fibre doesn’t receive as much attention as nutrients like protein, it’s often overlooked. However, eating enough fibre is associated with numerous health benefits and can be an important part of a balanced eating pattern.
Fortunately, increasing your fibre intake doesn’t require expensive supplements or specialised diets. Many everyday foods—including fruits, vegetables, whole grains, beans and nuts—are naturally rich sources of fibre.
At 1% Movement, we believe healthy eating should focus on practical habits rather than individual “superfoods.” Learning why fibre matters and where to find it can help you build meals that are both nutritious and satisfying.
In this article, you’ll learn what fibre is, why it matters, the different types of fibre and simple ways to include more fibre in your daily diet.
What Is Fibre?
Fibre is a type of carbohydrate that your body cannot fully digest.
Unlike other carbohydrates, which are broken down into glucose for energy, fibre passes through the digestive system largely unchanged.
Although fibre doesn’t provide energy in the same way as other carbohydrates, it performs many important functions that support overall health.
These include:
- Supporting healthy digestion.
- Helping maintain regular bowel movements.
- Supporting heart health.
- Contributing to feelings of fullness after meals.
- Feeding beneficial bacteria in the gut.
Because of these benefits, fibre is considered an essential component of a healthy eating pattern.
You’ll notice that many foods naturally high in fibre—such as fruits, vegetables, whole grains and legumes—are also rich in vitamins, minerals and other beneficial nutrients.
Why Fibre Matters
Eating enough fibre contributes to many aspects of health.
Research has shown that diets rich in fibre are associated with numerous health benefits, including supporting:
- Digestive health.
- Heart health.
- Healthy blood cholesterol levels.
- Healthy blood sugar regulation.
- Feelings of fullness after meals.
- Healthy weight management when combined with an overall balanced lifestyle.
Rather than viewing fibre as a nutrient only for digestion, it’s helpful to recognise that it contributes to many body systems.
This is one reason why dietary guidelines around the world encourage eating a variety of fibre-rich foods every day.
Types of Fibre
Although there are many forms of dietary fibre, they are commonly grouped into two main categories.
Soluble Fibre
Soluble fibre dissolves in water to form a gel-like substance during digestion.
It is found in foods such as:
- Oats
- Barley
- Apples
- Citrus fruits
- Beans
- Lentils
- Chia seeds
- Psyllium
Soluble fibre can help support healthy cholesterol levels and contribute to feelings of fullness after meals.
Insoluble Fibre
Insoluble fibre does not dissolve in water.
Instead, it adds bulk to stool and helps food move through the digestive tract.
Good sources include:
- Wholegrain bread
- Brown rice
- Wheat bran
- Nuts
- Seeds
- Many vegetables
Both soluble and insoluble fibre contribute to good health, which is why eating a variety of plant foods is recommended.
Fibre-Rich Foods
Many nutritious foods naturally provide fibre.
Examples include:
Fruits
- Apples
- Pears
- Berries
- Oranges
- Bananas
Vegetables
- Broccoli
- Carrots
- Spinach
- Brussels sprouts
- Sweet potatoes
Whole Grains
- Oats
- Brown rice
- Wholemeal bread
- Wholegrain pasta
- Quinoa
Legumes
- Lentils
- Chickpeas
- Kidney beans
- Black beans
Nuts and Seeds
- Almonds
- Walnuts
- Chia seeds
- Flaxseeds
- Sunflower seeds
Including foods from these groups regularly can help increase your fibre intake while also providing many other important nutrients.
How Much Fibre Do You Need?
Fibre requirements vary depending on factors such as age, sex and overall energy intake.
Rather than focusing on a specific number each day, most people benefit from gradually increasing their intake of fibre-rich foods as part of a balanced eating pattern.
Increasing fibre intake is often easier and more sustainable when it comes from whole foods rather than relying on supplements.
If you currently eat very little fibre, increase your intake gradually and drink plenty of water. This can help your digestive system adjust more comfortably.
Practical Ways to Eat More Fibre
Improving your fibre intake doesn’t require a complete overhaul of your diet.
Small changes can make a meaningful difference over time.
Choose Whole Grains More Often
When possible, choose:
- Wholemeal bread instead of white bread.
- Brown rice instead of white rice.
- Wholegrain pasta.
- Oats for breakfast.
Whole grains generally provide more fibre than refined grains while also contributing additional vitamins and minerals.
Eat More Fruits and Vegetables
Aim to include fruits and vegetables throughout the day.
Simple ideas include:
- Adding berries to breakfast.
- Including a side salad with lunch.
- Snacking on fruit.
- Filling at least half your dinner plate with vegetables.
Eating a variety of colourful fruits and vegetables also increases your intake of other beneficial nutrients.
Include Legumes Regularly
Beans, lentils and chickpeas are among the richest natural sources of fibre.
They can easily be added to:
- Soups
- Salads
- Curries
- Stir-fries
- Pasta dishes
Legumes also provide plant-based protein, making them an excellent addition to balanced meals.
Snack on Nuts and Seeds
Nuts and seeds provide fibre together with healthy fats and other important nutrients.
Examples include:
- Almonds
- Walnuts
- Pistachios
- Chia seeds
- Flaxseeds
- Pumpkin seeds
Because they are energy-dense, enjoy them in appropriate portions as part of a balanced diet.
Fibre and Healthy Weight Management
Fibre-rich foods can contribute to feelings of fullness after meals.
This may make it easier for some people to feel satisfied between meals as part of an overall healthy eating pattern.
However, fibre alone is not a weight-loss solution.
Healthy weight management depends on many interconnected lifestyle factors, including:
- Balanced nutrition.
- Regular physical activity.
- Quality sleep.
- Stress management.
- Appropriate portion sizes.
This reflects the principles of Lifestyle Medicine, where long-term health is supported by multiple healthy habits working together rather than relying on one nutrient or food.

Common Fibre Myths
Nutrition myths often create unnecessary confusion about fibre.
Myth 1: Fibre is only important for digestion.
No.
Although fibre is well known for supporting digestive health, it also contributes to heart health, healthy blood sugar regulation and feelings of fullness after meals.
Myth 2: Fibre supplements are better than food.
Not usually.
Whole foods provide fibre together with vitamins, minerals and many other beneficial compounds that supplements cannot fully replace.
Whenever possible, aim to obtain most of your fibre from a varied diet.
Myth 3: Only vegetables contain fibre.
No.
Many foods contain fibre, including:
- Fruits
- Whole grains
- Beans
- Lentils
- Nuts
- Seeds
Eating a variety of plant foods is the best approach.
Myth 4: More fibre is always better.
Not necessarily.
Very large increases in fibre over a short period may lead to bloating or digestive discomfort for some people.
Increasing fibre gradually while drinking enough water is generally recommended.
