Consumers increasingly prioritize fiber in their diets, building on the momentum from the recent protein surge.
Social Media Ignites a Fiber Revolution
A viral trend known as fibermaxxing has exploded on platforms like TikTok, where videos garner over 150 million views.[1][2] Participants share recipes featuring chia seeds, chickpeas, and overnight oats to hit 30 grams or more daily. This movement emerged in 2024 and accelerated through 2025, drawing Gen Z focused on gut health.[3]
Surveys reveal strong consumer interest. Nearly 70 percent of Americans aim to boost fiber intake, a seven-percentage-point rise since 2023.[4] Another poll showed 64 percent actively seeking more fiber, second only to protein.[3] Yet, over 95 percent fall short of recommendations, averaging just 15 grams daily against targets of 25 grams for women and 38 grams for men.[5]
Proven Health Advantages Propel Popularity
Fiber supports digestion by feeding gut bacteria and easing bowel movements. Soluble types from oats and beans form a gel that lowers cholesterol and stabilizes blood sugar, while insoluble varieties from whole grains speed food transit.[5] Studies link higher intake to reduced risks of heart disease, diabetes, colon cancer, and even improved mental health via the gut-brain axis.[1]
The nutrient also promotes fullness for weight management and triggers natural GLP-1 production, mimicking effects of popular drugs like Wegovy.[2] Benefits extend to better skin, cognition in older adults, and overall longevity. Protein-heavy diets often sidelined fiber, creating a gap now addressed by this shift.[4]
Food Companies Race to Fortify Products
Major brands launched fiber-enhanced items throughout 2025. PepsiCo introduced Prebiotic Cola and upgraded SunChips and popcorn lines.[2] Cereal bars and bran cereals proliferated at retailers like Kroger.[5] High-fiber claims on packaging grew, with sales rising six percent annually from 2019 to 2024.[4]
Executives voiced optimism. PepsiCo CEO Ramon Laguarta declared, “Fiber will be the next protein,” citing widespread dietary deficiencies.[2] McDonald’s CEO Chris Kempczinski predicted fiber would dominate 2026 menus. Whole Foods anticipated more fiber callouts in its trends forecast.[2]
