Fibre is becoming a major food trend as brands add prebiotics and fibre to soda, yoghurt, snacks and everyday foods amid rising gut-health interest.
From prebiotic soda and fibre-fortified yoghurt to snacks and everyday staples, the nutrient once associated with bran is becoming a major food-industry growth story.
Haven Trends Food & Consumer Trends Desk
Fibre is rapidly moving beyond cereal and whole grain bread as food companies add it to drinks, yoghurt, snacks and convenience foods. The shift reflects growing consumer interest in gut health, satiety and functional nutrition.
Introduction: Is Fibre Becoming the New Protein?
For years, protein dominated the food industry's health conversation.
It moved from gym bags and sports nutrition into yoghurt, breakfast cereals, coffee, snack bars, desserts and ready-to-drink beverages. Now another nutrient is following a remarkably similar path.
Fibre is moving from the nutritional fine print to the front of the package.
Recent industry analysis from Australia suggests fibre is becoming one of food and beverage's fastest-growing functional ingredients, appearing in products ranging from yoghurt and snacks to soft drinks. ANZ describes the development as increasingly similar to the rise of protein, while food-industry analysts have been asking whether fibre could become the next major nutrition platform.
The commercial signals are already visible.
In the United States, PepsiCo's Pepsi Prebiotic Cola is now available nationwide, containing 3 grams of prebiotic fibre per can. In the UK, Poppi's prebiotic soda launched at Tesco and Pret in March as the brand's first international expansion. In Australia, food manufacturers are putting protein and fibre into an expanding range of everyday products as consumers become more interested in functional nutrition.
This is no longer just a nutrition conversation. It is becoming a product-development, retail and consumer-behaviour story.
Background: How Fibre Moved From Bran to Beverages
Fibre has traditionally been associated with whole grain bread, bran cereal, oats, beans, fruit and vegetables.
Those foods remain important sources. But the latest trend is different: manufacturers are trying to put fibre into products people already buy.
That means yoghurt can carry a fibre claim. A snack bar can provide added fibre. A wrap can be reformulated. A beverage can contain prebiotic fibre. Even cola is now part of the conversation.
The strategy resembles what happened with protein.
Food companies discovered that consumers did not necessarily want to radically change their eating habits. They wanted familiar products with an additional nutritional benefit.
The result was protein-fortified versions of everyday foods.
Fibre is now following that playbook.
ANZ food and agribusiness analyst Michael Whitehead says fibre is increasingly appearing across categories where consumers would not traditionally expect it, while describing the movement as having characteristics similar to the earlier protein boom.
What is the difference between fibre and prebiotic fibre?
Fibre is a broad category of carbohydrate that the body does not fully digest.
Some fibres have physiological effects beyond simply contributing bulk to the diet. Prebiotics are substances that are selectively utilized by microorganisms in ways associated with a health benefit; many prebiotics are fibres, but not every fibre is a prebiotic.
That distinction matters as marketing around gut health becomes more prominent.
Consumers should therefore look beyond a front-of-pack claim and check the ingredient list and nutrition panel to understand what a particular product actually contains.
Why the Fibre Trend Is Growing
Gut health has become mainstream
One of the biggest forces behind fibre's rise is the growing public conversation around gut health.
Terms such as microbiome, probiotics, prebiotics and digestive health have moved from specialist nutrition discussions into advertising, social media and supermarket marketing.
Food Navigator reported earlier this year that fibre, prebiotics and gut health are increasingly connected with broader longevity-focused food innovation. The publication identified new launches designed around digestion, satiety, strength and long-term wellbeing.
The shift gives manufacturers a simple proposition: instead of selling a product only for taste, they can sell it as part of a broader wellness routine.
Consumers are looking for convenient nutrition
Modern consumers do not always want to add another food preparation task to their day.
That is why functional ingredients are increasingly appearing in foods that already fit existing routines.
A yoghurt can be eaten at breakfast. A cereal bar can become a snack. A drink can be picked up on the way to work.
The food does not have to feel medicinal or complicated.
This is one reason fibre could follow protein's trajectory: the ingredient can be added to familiar occasions rather than requiring consumers to adopt a completely new diet.
The fibre gap creates a commercial opportunity
ANZ reports that only about 28% of Australian adults meet recommended fibre intake levels. It cites Australian guidance of around 38 grams a day for adult men and 28 grams for adult women.
That gap gives food manufacturers an obvious opportunity.
But it also creates a responsibility: a fibre claim should complement, rather than replace, a balanced diet based on a variety of whole foods.
Social Media Is Helping Turn Fibre Into a Lifestyle Trend
Protein became a social-media phenomenon partly because it was easy to quantify.
People could post their daily protein totals, compare protein-packed breakfasts and share recipes designed to increase intake.
Fibre is now developing a similar online language.
“Fibremaxxing” is appearing in social-media discussions, with users sharing ways to increase fibre intake through foods such as chia seeds, oats, beans and other plant foods. ANZ specifically identifies the emergence of this online conversation as part of fibre's wider transition into mainstream food culture.
The attraction is straightforward.
Fibre can be turned into a challenge:
How much can I get into my breakfast?
Which snack has the most fibre?
Can I increase fibre without changing what I normally eat?
That type of content is highly compatible with TikTok, Instagram and YouTube, where simple food swaps and nutritional comparisons can generate substantial engagement.
But social media also introduces a risk.
Users may focus on hitting a number without understanding the broader nutritional context.
The best fibre-focused content therefore emphasizes food quality and dietary variety rather than treating fibre as a competition.
Consumer Behaviour: The Nutrient Is Becoming a Shopping Signal
The supermarket is perhaps the clearest indication that fibre's role is changing.
Consumers increasingly encounter functional claims while shopping for ordinary foods.
Instead of looking only for “whole grain” or “high in fibre,” shoppers may now see terms such as prebiotic, gut health, digestive health and functional nutrition.
This expands the potential market dramatically.
It also creates a new kind of consumer question:
Is the product genuinely better, or is fibre simply being used as a marketing hook?
That question is already emerging around protein.
Australian consumer group CHOICE reported in September that shoppers pay an average premium of about 50% for grocery products marketed as high-protein compared with conventional alternatives. Its analysis highlights how nutrition claims can materially affect what consumers pay.
Fibre products could face the same scrutiny.
Consumers may be willing to pay more for useful nutritional improvements, but they are likely to become increasingly interested in how much fibre they are actually getting for the extra cost.
Food Companies Are Building Fibre Into Everyday Products
Pepsi Prebiotic Cola takes fibre into a surprising category
One of the most visible examples is Pepsi Prebiotic Cola.
PepsiCo launched the product nationwide in the United States in February after a limited online release. The company says each 12-ounce serving contains 3 grams of prebiotic fibre, 5 grams of sugar and 30 calories in the product's stated formulation.
Pepsi's current product information lists soluble corn fibre among its ingredients and identifies 3 grams of dietary fibre per serving.
The significance is not that consumers suddenly need fibre from cola.
It is that a legacy soft-drink category is being redesigned around a functional ingredient.
That shows just how far the functional-food strategy has travelled.
Poppi's UK expansion shows the trend crossing markets
PepsiCo-owned Poppi brought its prebiotic soda brand to the UK in March, with an initial rollout through Tesco and Pret before a wider expansion. Beverage industry reporting described the UK as the brand's first international market.
The launch is important because it demonstrates that the modern functional soda movement is not confined to the United States.
Australia is becoming a major testing ground
Australian manufacturers are also responding.
ABC News reported in June that protein-enhanced foods had spread well beyond sports nutrition into yoghurt, pasta, bread, cereals, snacks and protein-infused water. The story also highlighted a new Australian facility producing high-protein peanut powder for food manufacturers.
That matters for the fibre story because it shows how functional nutrition ingredients can reshape the wider food-manufacturing ecosystem.
The next stage is likely to involve combinations rather than single-nutrient products: protein plus fibre, fibre plus prebiotics, or fibre plus other functional ingredients.
The Business and Restaurant Impact
The rise of fibre fits into a broader transformation in how food companies compete.
Taste remains essential. But brands increasingly want their products to deliver another reason to buy.
A fibre claim can provide that reason.
For manufacturers, fibre can become a platform for:
New product launches
Reformulation
Premium pricing
Gut-health positioning
Functional beverages
Better-for-you snacks
Breakfast innovation
Convenience foods
For retailers, it creates new shelf categories and new consumer conversations.
For restaurants and cafés, the opportunity is somewhat different.
Rather than simply advertising fibre content, operators can incorporate naturally fibre-rich ingredients into bowls, breakfast dishes, smoothies, wraps and plant-forward meals.
The biggest opportunity may be to make higher-fibre eating feel normal rather than clinical.
Health Considerations: More Fibre Does Not Automatically Make a Product Healthy
This is where consumers need to be careful.
A product can contain added fibre and still be high in sugar, saturated fat, sodium or calories.
A fibre-fortified biscuit is still a biscuit. A prebiotic soda is still a soft drink.
The presence of a functional ingredient should not erase the rest of the nutrition label.
Consumers should also distinguish between naturally fibre-rich foods and heavily formulated products with isolated or added fibres.
Whole grains, legumes, fruits, vegetables, nuts and seeds provide fibre alongside other nutrients and food components.
For people who dramatically increase fibre intake, gastrointestinal discomfort can occur, particularly if the increase is sudden. Gradual changes and adequate fluid intake are commonly advised, although individual dietary needs vary.
People with gastrointestinal conditions or medically prescribed diets should seek advice from a qualified healthcare professional before making major dietary changes.
Benefits and Criticisms of the Fibre Boom
The potential benefits
Better awareness: The trend is encouraging consumers to pay attention to a nutrient many people overlook.
More convenient choices: Added fibre can make it easier to increase intake within existing eating routines.
Product innovation: Manufacturers are developing new ways to incorporate fibre without radically changing familiar foods.
Gut-health awareness: The trend has brought digestive health into mainstream food conversations.
Agricultural opportunities: Rising demand can create new markets for grains, pulses and fibre ingredients.
The criticisms
Marketing inflation: Not every product carrying a fibre claim is nutritionally impressive.
Higher prices: Functional claims can come with substantial premiums.
Overconsumption of fortified products: Consumers may mistake functional foods for substitutes for a varied diet.
Confusing terminology: Fibre, prebiotics and probiotics are not interchangeable concepts.
Trend fatigue: If every product becomes “high fibre,” consumers may eventually become skeptical of the claim.
Real-World Examples to Watch
Pepsi Prebiotic Cola
A traditional cola with added prebiotic fibre demonstrates how functional nutrition is entering mainstream soft drinks.
Poppi in the UK
The brand's move into Tesco and Pret demonstrates the international expansion of the modern prebiotic soda category.
Fibre-fortified everyday foods
Industry reporting is tracking fibre additions across yoghurt, wraps, cereals, snacks and beverages, showing that the trend is spreading across categories rather than remaining confined to specialist health foods.
Protein-and-fibre combinations
Quaker's Oat Shake & Go, launched in the United States in July, provides an example of the convergence. PepsiCo says the product delivers protein, wholegrain oats and fibre in a portable shake format.
That combination could become increasingly important as consumers seek multiple nutritional benefits from convenient foods.
Verified Expert Insight: Is Fibre Really the New Protein?
The phrase should be treated as a trend description, not a scientific verdict.
Michael Whitehead, Executive Director of Food, Beverage and Agribusiness Insights at ANZ, argues that fibre is beginning to exhibit characteristics similar to those that helped protein become a major marketing platform.
Food-industry analysts have made similar observations.
Food Navigator's 2026 trend reporting identified fibre as a major challenger to protein because of growing interest in gut health and satiety, while noting that protein itself remains a powerful food trend.
The more accurate conclusion is therefore not that protein has disappeared.
It is that the functional-nutrition conversation is expanding.
Protein remains important. Fibre is gaining ground. Consumers are increasingly interested in both.
Future Outlook: From “High Protein” to “High Function”
The next stage of food innovation may be less about one superstar nutrient and more about combinations.
Expect to see products positioned around several attributes simultaneously:
Protein plus fibre
Fibre plus prebiotics
Lower sugar plus fibre
Whole grains plus protein
Gut-health positioning plus convenience
Functional drinks with multiple nutritional claims
That could produce better products—but it could also produce more complicated labels.
The winners will probably be brands that can make the nutritional proposition understandable without turning every package into a chemistry lesson.
There is also an opportunity for naturally fibre-rich foods to benefit from the trend.
Consumers may become more interested in beans, lentils, whole grains, fruits, vegetables, nuts and seeds as they learn more about fibre.
That would be a healthier outcome than simply adding isolated fibre to highly processed foods.
Conclusion: Fibre's Biggest Opportunity May Be Simplicity
The rise of fibre is not really about replacing protein.
It is about the food industry discovering another powerful way to make everyday products feel more relevant to modern consumers.
Protein taught brands that shoppers will pay attention when a familiar product promises a clear nutritional benefit.
Fibre is now entering that same space.
From Pepsi's prebiotic cola to fibre-fortified yoghurt, snacks and convenience foods, manufacturers are finding increasingly creative ways to put the nutrient in front of consumers.
The challenge will be maintaining credibility.
Consumers will increasingly ask whether a fibre claim represents meaningful nutritional value—or simply a clever marketing strategy.
The brands that answer that question honestly could benefit from one of the most important food trends currently taking shape.
Fibre may not replace protein. It may simply become the next essential part of the modern food label.
