Fibre moves mainstream
- U.K. industry coverage says high‑fibre foods have shifted from niche social-media trends into mainstream consumer demand. - Reports note manufacturers are innovating with fiber-forward products to meet growing health-focused preferences. - Analysts frame fiber as a major product trend shaping new product development and marketing in the U.K. food sector.

High-fibre food has moved from a social-media habit to a mainstream U.K. product strategy, with two trade publications on April 21 putting fibre at the center of 2026 food launches and marketing. (foodmanufacture.co.uk, foodnavigator.com) Food Manufacture listed “Healthy F&B: What the modern consumer wants” as an editor’s choice on April 21, 2026, and FoodNavigator published “How fibre went from forgotten nutrient to consumer obsession” the same day in its reformulation coverage. (foodmanufacture.co.uk, foodnavigator.com) The shift is happening against a nutrition gap the industry can market into: U.K. guidance says adults should get 30 grams of fibre a day, while British dietitians say average adult intake is about 18 grams. (gov.uk, bda.uk.com) Fibre is the part of plant food the small intestine does not digest, so it reaches the large intestine and helps with bowel function, fullness and, in some cases, cholesterol and blood-sugar control. The British Nutrition Foundation says most U.K. adults still do not eat enough of it. (nutrition.org.uk) That leaves manufacturers room to add fibre to products that were previously sold on protein, low sugar or “gut health” claims. Mintel said last year that protein claims had doubled globally over a decade while high- or added-fibre claims had stayed relatively flat, leaving fibre underused by brands. (mintel.com) Trend forecasters are now pointing the other way. Hatch’s 2026 food and beverage report said “fibremaxxing” was spilling from TikTok into desserts, crisps, snack bars and functional drinks, while Innova Market Insights put gut health at the top of its 2026 food-and-beverage trend list. (hatch.group, nutritioninsight.com) The U.K. policy backdrop also changed this year. Government guidance says new restrictions on advertising less healthy food and drink on television and paid online media took effect on January 5, 2026, pushing brands toward products and claims that fit a healthier brief. (gov.uk, asa.org.uk) Brands still have to be careful about what “high fibre” means on pack and in ads, because fibre is not one ingredient and different fibres behave differently in the body. The British Dietetic Association distinguishes between soluble fibre, insoluble fibre, resistant starch and prebiotics, and says people should get fibre from a range of foods including wholegrains, pulses, fruit, vegetables, nuts and seeds. (bda.uk.com) For now, the commercial case is simple: a nutrient most adults underconsume has become easier to sell, easier to formulate around and easier to tie to gut-health messaging. That is why fibre is showing up less as a niche wellness tip and more as a mainstream U.K. food brief. (foodnavigator.com, nutrition.org.uk)
