Fibermaxxing Takes Over: How High-Fiber Foods Are Dominating 2026 Trends

Fiber is poised to become the next big food trend by 2026, with a strong focus on high fiber foods. The push for fiber comes after previous trends in hydration and protein. McDonald’s CEO has emphasized focus on fiber for 2026, while Whole Foods predicts a rise in products with clear 'fiber-forward' labels. Snacks such as chips, popcorn, and crackers will lead the way, often made with legumes and beans.

PepsiCo is rolling out fiber-enhanced versions of SunChips, Smartfood popcorn, and Propel hydration packets. Meanwhile, store-brand products are also joining the market, offering affordable high-fiber options. The trend, dubbed 'fibermaxxing,' has gained traction on TikTok, with Gen Z users prioritizing stomach health. Scientifically, fiber boosts the hormone GLP-1, which helps suppress appetite. Surveys show 52% of consumers want to try 'fibermaxxing,' and 42% believe high-fiber foods are healthier. Major food brands are now racing to meet this demand with new product lines. Beyond food, fiber technology is advancing rapidly. Companies like Nokia, Cisco, Huawei, and Ciena have recently launched high-capacity fiber transport systems, including Nokia’s 1830 PSS-32e, Cisco’s NCS 1010 for 800G optics, and Ciena’s 6500-X series for 400G+ networks. This surge in both dietary and tech-related fiber points to a broader cultural shift.

The fiber trend is gaining momentum, with food giants and retailers expanding their offerings. As consumer interest grows, more products will feature added fiber to meet demand. The combination of health benefits, affordability, and tech advancements suggests fiber will remain a dominant focus in coming years.
