For years, protein has dominated the functional food conversation — today, another nutrient is rapidly emerging to fuel significant investment and M&A activity across the food and beverage industry. Consumers have historically rewarded brands that promised higher protein, whether in shakes, bars, snacks or beverages. In 2026, fiber — once viewed primarily as a digestive health ingredient — is now being repositioned as a key part of overall wellness, with growing consumer awareness around gut health, microbiome diversity, blood sugar management, satiety and metabolic health. Strategic acquirers and private equity investors are beginning to evaluate fiber-forward brands through the same lens that has been applied to protein, as a result. This includes assessing large addressable markets, differentiated product offerings and significant runway for growth.

This category is still in its early innings, but the momentum suggests fiber may become one of the next major investment themes within the broader food and beverage sector.

WHY M&A PROFESSIONALS ARE WATCHING THE CATEGORY

Although the broader food and beverage M&A market remains disciplined in 2026, buyers continue to aggressively pursue brands that exhibit strong consumer loyalty, differentiated positioning, resilient margins and attractive long-term growth profiles.

Strategic buyers and private equity investors remain particularly focused on businesses offering functional health benefits, proprietary formulations, differentiated brands and clear avenues for organic growth. At the same time, buyers continue to exercise significant discipline around valuation and diligence.

Fiber-focused businesses possess several characteristics that align well with these investment priorities:

  • Large whitespace opportunity: Despite widespread nutritional deficiencies, fiber remains substantially underpenetrated compared other categories 
  • Multiple product applications: Innovation extends beyond nutrition bars into beverages, cereals, baked goods, snacks, dairy alternatives, supplements and ingredient platforms
  • Premium positioning: Consumers increasingly demonstrate a willingness to pay for products combining wellness benefits with superior taste and clean ingredients
  • Ingredient platform potential: Proprietary fiber technologies may become just as valuable as branded consumer products by enabling innovation across multiple food categories
  • Sustainability differentiation: Upcycled ingredients provide an additional environmental, social and governance narrative that many strategic buyers value

Importantly, the investment opportunity extends beyond consumer brands. As manufacturers reformulate products to improve nutritional profiles, suppliers of proprietary fiber technologies and ingredients may also become attractive acquisition targets. Differentiated ingredient businesses have historically commanded premium valuations because they enable innovation across multiple brands and product categories.

CONSUMERS ARE PAYING ATTENTION TO FIBER

There has always been a substantial opportunity for brands that can make fiber both convenient and enjoyable, as approximately 95% of Americans do not consume the recommended daily amount of fiber. 

Unlike earlier generations of fiber products that focused almost exclusively on digestive regularity, today's brands are positioning fiber as a solution for a much broader set of consumer health priorities, including:

  • Gut microbiome health
  • Blood sugar management
  • Satiety and weight management
  • Heart and metabolic health
  • Plant diversity and whole-food nutrition

These trends align with consumer preferences for functional foods that provide measurable health benefits while maintaining clean labels and exceptional taste.

FLOURA FIBER DEMONSTRATES THE EVOLUTION OF THE CATEGORY

One example of this shift is Floura Fiber, the company founded by Jeni Britton, creator of Jeni's Splendid Ice Creams. After building one of America's most recognizable premium ice cream brands, Britton turned her attention to helping consumers address the nation's fiber gap through products focused on functional nutrition, plant diversity and sustainability. Floura produces prebiotic fiber from upcycled fruits and vegetables, including apple cores, pineapple rind and fermented watermelon rind, rather than relying on isolated fiber additives. 

The company's growth reached a significant milestone in August 2026, when Starbucks introduced Floura's Blueberry Matcha Daily Fiber Bar at company-operated stores nationwide. The launch marked Floura's first major national retail rollout following strong direct-to-consumer growth across its own website, Amazon, TikTok Shop and more than 300 independent retailers.

National distribution through Starbucks serves as meaningful third-party validation that fiber-focused products are transitioning from niche wellness products into mainstream consumer offerings. Historically, these types of inflection points have often attracted strategic and financial sponsor interest as buyers seek exposure to emerging consumer trends before categories mature. Examples include Kellogg's acquisition of RXBAR, Mars' acquisition of KIND, and Coca-Cola's acquisition of BodyArmor, each occurring after the brands had demonstrated meaningful consumer traction and expanding retail distribution.

FIBER ALIGNS WITH SEVERAL OF THE STRONGEST CONSUMER TRENDS

Fiber is benefiting from the convergence of multiple investment themes that have attracted capital across food and beverage brands over the past several years. First, consumers continue to prioritize functional nutrition and seek products that deliver value beyond basic nourishment. Digestive health, metabolic wellness, immune support and healthy aging remain among the fastest-growing functional claims, and investors often favor brands supported by differentiated formulations or proprietary ingredients.

Second, increasing consumer awareness surrounding GLP-1 medications has accelerated interest in foods that promote satiety, blood sugar stability and overall digestive health. Protein has traditionally dominated this discussion, but fiber is increasingly recognized as a complementary nutritional component that supports these same consumer objectives.

Lastly, sustainability continues to influence purchasing decisions. Companies incorporating upcycled ingredients into their products can simultaneously appeal to environmentally conscious consumers while creating differentiated brand stories. Floura's utilization of produce that would otherwise become waste illustrates how sustainability and nutritional innovation can reinforce one another.

WHAT THIS MEANS FOR FOOD AND BEVERAGE FOUNDERS

Founders building businesses within the fiber category should understand that investor enthusiasm will not be driven solely by revenue growth. As with virtually every consumer transaction today, buyers are placing heightened emphasis on the underlying quality and sustainability of earnings. Areas often receiving particularly rigorous diligence include:

  • Contribution Margin After Marketing (CMAM) by product and channel
  • Ingredient concentration and sourcing risk
  • Gross margin sustainability
  • Channel economics and concentration
  • Claims/regulatory diligence
  • Inventory/shelf-life considerations
  • Customer acquisition cost and lifetime value
  • Retail velocity and repeat purchase behavior
  • Promotional efficiency
  • SKU-level profitability
  • Supply chain scalability
  • Working capital requirements

Brands capable of demonstrating disciplined unit economics alongside compelling consumer demand can distinguish themselves, as competition within the category continues to increase.

LOOKING AHEAD

Fiber is becoming one of the more compelling consumer trends to watch. While meaningful M&A activity focused specifically on fiber brands has yet to emerge, history suggests that sustained consumer adoption, expanding retail distribution and differentiated ingredient innovation are often the types of signals that precede increased acquisition activity.

Fiber, today, is benefiting from a long-term shift in consumer preferences. Shoppers expect food to deliver more than calories or convenience — they want products that support their health, align with their values and are produced more sustainably.

The emergence of companies like Floura illustrates how these themes are beginning to converge. A founder best known for premium ice cream is now building a business centered on fiber, plant diversity and upcycled ingredients, highlighting the growing intersection of health and wellness, sustainability and functional nutrition.

For M&A professionals, that convergence may be the more important story. While the broader food and beverage market remains disciplined, buyers may reward businesses positioned around durable consumer preferences rather than short-term product fads. As these secular trends shape purchasing behavior, fiber-focused brands — and the ingredient platforms supporting them — appear well positioned to attract continued strategic and financial interest.
