Get ready for a fiber revolution! It's time to say goodbye to the protein-centric diets of the past and embrace the rising star of nutrition: fiber.
In the world of health and wellness, trends come and go, but fiber is poised to take center stage. With a growing focus on stomach health, especially among Gen Z, the 'fibermaxxing' trend has taken the TikTok world by storm. People are seeking ways to maximize fiber intake, and major food companies are jumping on the bandwagon with innovative fiber-focused products.
Sherry Frey, a health and wellness thought leader at NIQ, highlights the consumer demand for improved digestion and gut health. She emphasizes that the younger generation understands the link between digestive well-being and overall health, including better skin and cognitive function.
Dataessential, a research firm, found that over half of consumers are eager to try 'fibermaxxing' after learning about the trend, and a significant portion believe that 'high fiber' labels indicate healthier food choices.
Fiber builds upon previous wellness trends, Frey explains. First, there was the hydration craze, followed by the enduring popularity of protein. Now, fiber is the natural progression, creating a 'perfect storm' of converging trends.
But here's where it gets interesting: fiber has been scientifically proven to stimulate the production of GLP-1, an appetite-suppressing hormone similar to those found in weight-loss drugs like Wegovy.
The evidence of this trend is already visible on grocery store shelves. Whole Foods predicts a surge in fiber-forward products and packaging in 2026. Thrive Market, an online supermarket, has seen a 30% increase in fiber-related searches, with shoppers gravitating towards snacks, bars, and supplements.
Even major food companies are taking note. PepsiCo CEO Ramon Laguarta declared that 'fiber will be the next protein.' With the majority of Americans falling short of their daily fiber intake, Laguarta believes this trend will gain momentum.
PepsiCo is already enhancing its soda portfolio with fiber-forward products, such as the gut-friendly 'Pepsi Prebiotic Cola.' McDonald's CEO Chris Kempczinski also predicts that fiber will be a big deal in 2026, potentially signaling the fast-food giant's entry into this trend.
Snacks, particularly those made from legumes and beans, are expected to be the battleground for fiber innovation. However, taste remains a crucial factor, especially when it comes to plant-based ingredients.
'Consumers are willing to make compromises, but taste is non-negotiable,' says Frey. 'Even in challenging economic times, they're willing to pay a premium for these healthier options.'
This is where private labels from major grocery stores come into play. They are entering the wellness sector with fiber-enhanced products at more affordable prices. Aldi's in-house line, for example, offers 'better for you' soda and meal bar alternatives, while Walmart expands its Bettergoods lineup with plant-based options.
Medical experts recommend 25 grams of fiber per day for adult women and 35 grams for adult men. Paul Kriegler, a registered dietician, believes this trend is generally positive for health.
However, he cautions against relying solely on prepackaged products to meet fiber needs. He encourages consumers to prioritize fresh produce and vegetables, as the US government's new dietary guidelines also emphasize the importance of 'real food' and reducing highly processed foods.
'The key is to eat a large variety of vegetables every day,' says Kriegler. 'Ironically, many of the best sources of fiber are fresh and unlabeled, so you have to seek them out.'
So, will fiber live up to its hype? Only time will tell, but one thing is certain: the focus on gut health and fiber intake is here to stay.
