Fibre is often overlooked, but it plays a crucial role in keeping your digestive system and overall health on track. Despite its importance, many adults are falling short of the recommended 25–30 grams per day, with the average intake hovering closer to 20 grams. This gap may seem small, but it can have a big impact on digestion, energy, and long-term health.
Why Fibre Deserves More Attention
Fibre isn’t just about keeping things “regular.” It also feeds the beneficial bacteria in your gut, helping to maintain a balanced microbiome. These bacteria produce short-chain fatty acids that support immunity, reduce inflammation, and even influence mood. Without enough fibre, your gut bacteria go hungry, and this can affect more than just digestion.
Here are some of the biggest benefits of getting enough fibre:
- Better gut health – encourages a thriving, balanced gut microbiome.
- Smooth digestion – prevents constipation and supports regularity.
- Satiety and weight management – helps you feel fuller for longer and curbs cravings.
- Stable blood sugar – slows down the absorption of sugar and prevents energy crashes.
- Heart health – supports healthy cholesterol levels by lowering LDL cholesterol.
Are You Meeting Your Fibre Needs?
Research shows that the majority of people aren’t getting enough fibre, and diets high in processed foods are a big reason why. Older adults are particularly vulnerable, often eating even less fibre than younger groups—despite needing it most to support digestion and heart health.
The Three Main Types of Fibre
Not all fibre works in the same way. Each type plays a different role in supporting your body:
- Soluble fibre – dissolves in water to form a gel-like texture, slowing digestion and helping balance blood sugar and cholesterol.
- Found in oats, apples, legumes, flaxseeds, and citrus fruits.
- Insoluble fibre – adds bulk to stool, supporting healthy bowel movements and reducing the risk of constipation.
- Found in whole grains, nuts, seeds, and the skins of fruits and vegetables.
- Resistant starch – bypasses digestion in the small intestine and becomes food for beneficial gut bacteria.
- Found in cooked and cooled potatoes, lentils, green bananas, and whole grains.
What 30 Grams of Fibre Looks Like
Reaching the daily goal may sound tricky, but it’s achievable with simple food choices. A single day could include:
- One banana (3g)
- Half an avocado (5g)
- Two slices of whole grain bread (6g)
- A handful of almonds (4g)
- One cup of lentils (10g)
- A kiwifruit (5–6g)
These everyday foods add up quickly, showing that small swaps can make a big difference.
Easy Ways to Add More Fibre
- Start the day with oats, whole grain toast, or a smoothie blended with chia or flaxseeds.
- Choose wholemeal pasta, quinoa, or brown rice over refined options.
- Load your meals with vegetables, fruits, and legumes.
- Snack on nuts, seeds, or fibre-rich snack bars.
Can You Overdo It?
While fibre is essential, increasing your intake too quickly can cause bloating, cramping, or changes in bowel habits. The best approach is to add fibre gradually and stay well hydrated to keep digestion smooth.
Final Thoughts
Fibre is one of the simplest yet most powerful ways to support your health. From feeding your gut bacteria to balancing blood sugar and improving heart health, it does far more than just aid digestion. With a few mindful food choices each day, you can close the fibre gap and enjoy the benefits of a healthier, happier gut.
