Protein has become the superstar nutrient. Protein powders are everywhere.
Protein bars fill supermarket shelves. People track grams of protein, calculate protein per meal, and ask:
“How much protein should I eat?”
And that’s not necessarily a bad thing.
Protein is essential for muscle, tissue repair, enzymes, hormones and many other functions.
But there is another nutrient that deserves considerably more attention: Fibre.
In fact, we could make a provocative argument: Fibre is the new protein.
Not because fibre replaces protein. It doesn’t.
But because many people are finally realising that protein alone does not create a healthy diet.
What Does Fibre Actually Do?
Dietary fibre is found predominantly in plant foods and passes through the digestive system differently from digestible carbohydrates.
Different fibres have different properties.
Some add bulk and support bowel regularity.
Others are fermented by gut microorganisms.
Some can influence blood glucose and cholesterol metabolism.
And certain fibres act as substrates for beneficial gut microbes.
A systematic review of 64 studies involving more than 2,000 healthy adults found that fibre interventions could increase certain beneficial bacterial groups and influence production of short-chain fatty acids such as butyrate.
Fibre Feeds Your Gut Microbiome
This may be one of the most fascinating reasons to pay attention to fibre.
Your gut microbiome is influenced by what you eat.
Certain dietary fibres reach the colon where they can be fermented by microorganisms.
This produces metabolites—including short-chain fatty acids—that are being extensively studied for their roles in gut and metabolic health.
But here’s the key:
Different fibres feed different microbes.
So instead of obsessing over one “super fibre,” diversity matters.
Think:
Beans + lentils + vegetables + fruit + whole grains + nuts + seeds
rather than one fibre supplement every day.
Fibre and Heart Health
The relationship between fibre and cardiovascular health is particularly compelling.
A large systematic review and meta-analysis found that greater dietary fibre intake was associated with lower cardiovascular disease and coronary heart disease risk.
More recent evidence continues to support the importance of adequate fibre intake as part of an overall healthy dietary pattern.
Some fibres can also help influence cholesterol levels.
This is one reason fibre should be considered a whole-body nutrient, rather than simply something that helps digestion.
Fibre and Blood Sugar
Fibre can also influence the way carbohydrates are digested and absorbed.
Higher dietary fibre intake has been associated with improvements in several cardiometabolic markers, including fasting glucose, insulin resistance and blood pressure in research syntheses.
This doesn’t mean fibre “cures” diabetes.
It means that a fibre-rich dietary pattern can be an important part of metabolic health.
How Much Fibre Do We Need?
A practical target for many adults is approximately:
25–30+ grams per day
Recommendations vary by country, age and sex, but 25–30 g or more daily is widely recommended for adults.
The challenge?
Many people don’t come close.
And the easiest way to increase fibre isn’t necessarily to buy a supplement.
It is to eat more plants.
The Fibre 10
Try building your diet around these fibre-rich foods:
1. Lentils
Excellent combination of fibre and plant protein.
2. Chickpeas
Easy to add to salads, curries and hummus.
3. Beans
One of the most fibre-dense food groups.
4. Oats
A convenient source of soluble fibre.
5. Chia Seeds
Small but exceptionally fibre-rich.
6. Flaxseeds
Provide fibre plus plant omega-3 ALA.
7. Berries
Fruit plus fibre plus polyphenols.
8. Broccoli
Fibre-rich and nutrient-dense.
9. Apples and Pears
Keep the edible skin when appropriate for additional fibre.
10. Nuts
Almonds, pistachios and other nuts provide fibre alongside healthy fats.
Don’t Forget the Fibre + Protein Combination
This is where the conversation gets really interesting.
Instead of:
Protein vs Fibre
think:
Protein + Fibre
For example:
Greek yoghurt + berries + chia
Eggs + avocado + whole-grain toast
Lentils + vegetables + brown rice
Chicken + quinoa + roasted vegetables
Salmon + broccoli + beans
Now you’re supporting multiple nutritional priorities at the same time.
Increase Fibre Slowly
If your current diet is relatively low in fibre, don’t suddenly double your intake overnight.
A rapid increase can cause:
- Bloating
- Gas
- Abdominal discomfort
Increase gradually and drink enough fluids.
The NIDDK also recommends increasing fibre gradually and consuming adequate liquids to help fibre work effectively.
What About Fibre Supplements?
Food should generally be the first choice.
But fibre supplements such as psyllium can sometimes be useful when dietary intake is inadequate or when recommended by a healthcare professional.
The important point is that one fibre supplement cannot replicate the diversity of fibre-containing whole foods.
Different plants provide different types of fibre and other beneficial nutrients.
Think diversity, not just dosage.
The Fitcart Takeaway
Protein deserves its place.
But perhaps we’ve spent too long asking:
“How much protein are you getting?”
and not enough time asking:
“How much fibre—and how much plant diversity—are you getting?”
For long-term health, your plate needs more than protein.
It needs plants, fibre, colour, diversity and quality.
So perhaps the next nutrition revolution isn’t:
Protein vs Fibre.
It’s:
Protein + Fibre + Plants = Better Nutrition.

If you significantly increase your fibre intake, do so gradually and maintain adequate fluid intake. People with digestive disorders, swallowing difficulties, bowel conditions, or other medical concerns should seek personalised advice from a qualified healthcare professional.
Fibre supplements may interact with certain medications or affect medication absorption. Consult your healthcare professional or pharmacist when appropriate.
Supplements should complement a nutrient-dense diet rather than replace whole foods.
