Why high-fiber foods are taking over wellness in 2026—and beyond

Fiber is set to become the next major wellness trend in 2026, according to industry leaders. McDonald’s CEO has highlighted its growing importance, following past consumer focuses on hydration and protein. Food companies and retailers are now racing to meet demand with new high-fiber foods and packaging solutions.

The shift towards fiber comes as research shows its benefits for digestion and appetite control. The hormone GLP-1, which suppresses hunger, is triggered by fiber intake, making it appealing to health-conscious consumers. Currently, only 52% of people meet the recommended daily intake—25 grams for women and 35 grams for men.

Social media is driving the trend, with 'fibermaxxing' gaining traction on TikTok, especially among Gen Z. Over half of consumers express interest in trying fiber-rich foods, while 42% already view high-fiber options as healthier. Major brands are responding: PepsiCo is rolling out fiber-enhanced versions of SunChips, Smartfood popcorn, and Propel hydration packets. Snacks like chips and puffed crackers will see the biggest changes, with legume and bean-based foods leading innovation. Packaging is also evolving, with past successes like PAPACKS’ hemp-wood fiber boxes and ILLIG’s dry fiber systems paving the way for more sustainable solutions. Whole Foods predicts a surge in fiber-focused foods and packaging by 2026. Beyond food, telecom firms are expanding fiber infrastructure. Companies like KPN, Vodafone, and Deutsche Telekom are accelerating fiber-to-the-home (FTTH) rollouts, while IQGeo is upgrading network planning software. These developments signal fiber’s dual role in both nutrition and technology sectors.

The fiber trend is reshaping consumer habits and product development. With food giants and tech firms investing heavily, high-fiber foods will become more accessible. As awareness grows, the market is likely to see even broader adoption of fiber-rich foods and advanced packaging solutions.
