Fibermaxxing in 2026 may bring more fiber-focused foods to shelves.

Food companies and social media attention have helped push dietary fiber into the spotlight, while studies and health organizations report most U.S. adults still fall short of recommended daily fiber amounts.

Fiber is receiving renewed attention in 2026 as both companies and social platforms highlight it. PepsiCo has planned products such as fiber popcorn and chips, and Coca-Cola launched a prebiotic soda in 2025, according to reporting. On TikTok, the trend called "fibermaxxing" has many videos that discuss weight and gut benefits. Nutrition coach Hunter Stoler and Dr. Kellyann Petrucci are quoted explaining that fiber is indigestible, can affect feelings of fullness, and serves as food for gut bacteria. Reported details: - Less than 10% of U.S. adults meet recommended daily fiber intake, according to a study presented at Nutrition 2021 Live Online. - USDA and Harvard Health recommendations note adult women up to 50 need about 25 grams daily and men up to 50 about 38 grams; older adults have lower recommended amounts. - Typical U.S. adult intake is reported at about 10 to 15 grams of fiber per day, according to a Harvard Health blog from 2019. - PepsiCo's planned fiber snacks and Coca-Cola's 2025 prebiotic soda were reported as examples of product shifts toward fiber. - The TikTok "fibermaxxing" trend includes content claiming benefits for weight and gut health. Summary: Increased attention from brands and social platforms has brought fiber into public conversation and product development. Undetermined at this time.
