Wellness culture has found its latest obsession\u2014fiber. And not your grandmother\u2019s bran muffin version. It\u2019s Korean \u201ccutting\u201d jellies backed by Kylie Jenner, gummies fronted by Alix Earle and an entire TikTok subculture built around counting grams. But beneath the trendiness are the real questions: What is fiber, exactly? Which foods have it? And is the hype deserved? <\/p>\n
To answer the last one first: yes\u2014even the algorithm agrees. Per trend analytics platform Spate, fiber content is up nearly 300 percent year-over-year on Instagram, and fiber-forward drinks have surged more than 430 percent in overall popularity, largely fueled by TikTok creators. <\/p>\n<\/div>\n
Fiber\u2019s wellness glow-up may be recent, but the science isn\u2019t. A plant-based carbohydrate, fiber helps regulate digestion and blood sugar, explains board-certified holistic nutritionist Jennifer Hanway. \u201cIt creates more stable energy and reduces the physiological drive to eat every few hours,\u201d she says. <\/p>\n
The catch: Fiber isn\u2019t one-size-fits-all. \u201cSoluble fibers, like psyllium, chia and oat, tend to be gentler and better for blood sugar control, while insoluble fibers like wheat bran add bulk but can feel harsher if you\u2019re not used to them,\u201d Hanway explains. <\/p>\n
But people aren\u2019t here for the science; they\u2019re here to buy. Enter Alan Lin, founder of Liquid+ and better known to his 200,000 followers as \u201cFiber Daddy.\u201d He\u2019s not a doctor or dietitian, but he\u2019s built real trust by making an unglamorous topic approachable\u2014and his flagship product, Liquid Salad, has the packaging to prove even fiber can look cool now.<\/p>\n
Appetite for Control<\/h2>\n
Beneath the wellness branding is a very specific fantasy: a gut that behaves.<\/em><\/p>\n In the \u201990s\u2014fiber\u2019s last moment in the spotlight, if you can call it that\u2014it lived quietly, rarely discussed over cocktails. \u201cIt was associated with chalky orange drinks hidden in your grandparents\u2019 medicine cabinet,\u201d says Katie Wilson, cofounder of gut-health brand BelliWelli. This time, fiber isn\u2019t just visible\u2014it\u2019s sold as proof you have your life together.<\/p>\n Now, people want fiber that feels \u201cmodern and lifestyle-driven,\u201d Wilson says. And Spate\u2019s data backs her up: The format everyone\u2019s chasing is \u201croutine-friendly.\u201d On TikTok, that means \u201cloaded water\u201d (fiber and electrolytes stirred into a glass) and the \u201cinternal shower\u201d (a chia-and-citrus debloating fix)\u2014DIY rituals turning fiber into less a product than a routine.<\/p>\n Wilson is hardly alone in giving fiber a glow-up. Lin, the Liquid Salad creator, is part of the same wave\u2014and so, apparently, is Jenner, whose TikTok endorsement of Foodology\u2019s \u201ccutting jelly\u201d pulled over 21 million views. The pomegranate-flavored snack resembles what might happen if Jell-O and beef jerky had a wellness-era baby\u2014slightly bizarre, unmistakably algorithm-friendly. Earle, for her part, fronted a sponsored push for Physician\u2019s Choice\u2014one of the category\u2019s fastest-growing brands, per Spate, with a 293,000-plus jump in year-over-year interest.<\/p>\n But beneath the glossy packaging is real anxiety. Fiber is increasingly tied to conversations about colon cancer, PCOS and hemorrhoids, per Spate. In one case, that anxiety tracks with a real trend: Colorectal cancer rates in adults under 50 continue to climb by roughly 3 percent annually. And where there\u2019s worry, there\u2019s usually a product waiting to meet it.<\/p>\n As consumers chase better digestion, brands are racing to meet the demand.<\/em><\/p>\n The global dietary fiber market\u2014worth roughly $8 billion in 2023\u2014is projected to hit $15 billion by 2030. Per the new 2025\u20132030 Dietary Guidelines for Americans, adults should be getting somewhere between 28 and 34 grams of fiber a day, depending on age and sex. Fewer than 10 percent of us actually do.<\/p>\n That disconnect created an opening for founders like Lin. \u201cI\u2019ve been into health and wellness for about a decade, and I\u2019ve followed the same path a lot of people have\u2014paleo to keto to carnivore, and now landing somewhere more about balance,\u201d he says. \u201cI tried carnivore and it worked in some ways, but it wasn\u2019t sustainable. Reintroducing vegetables was a turning point\u2014when I was eating more fiber, I felt fuller and overate less. That\u2019s what stuck.\u201d<\/p>\n Meanwhile, brands like BelliWelli and Ponlu and Sakara Life are repackaging digestive health for the internet era; glossy and TikTok-ready, branding included. But old-school names are still cashing in too: Benefiber posted one of the category\u2019s largest absolute year-over-year gains, while MiraLAX\u2019s growth topped 1,000 percent. Grandma\u2019s medicine cabinet, it turns out, was ahead of its time.<\/p>\n Left to right: Sakara Fiber Bite (sold out); Ponlu The Jelly Stick ($32 for 10 sticks); BelliWelli Daily Fiber + Probiotics ($20 for 16 servings)<\/em><\/p>\n Fiber awareness is up. But actual intake? Not so much.<\/em><\/p>\n So is this fiber obsession actually making us healthier? Awareness is growing\u201473 percent of Americans believe fiber is good for their health, according to a 2026 International Food Information Council survey. Whether that translates into better eating habits is murkier.<\/p>\n Even the brands fueling the trend are careful not to oversell it. \u201cWhen you\u2019re eating a diverse, plant-rich diet, the fiber follows,\u201d says Danielle Duboise, cofounder of Sakara Life. \u201cThe powders and gummies are there for the days when life happens and meals don\u2019t.\u201d<\/p>\n Still, for all the \u201cfibermaxxing\u201d online, Americans consume roughly the same amount of fiber as decades ago. Federal dietary data shows average intake still hovers around 15 to 16 grams a day, which is well below recommended levels. To Duboise, that disconnect reflects a wellness culture that can tip into \u201canti-nourishment,\u201d reducing food to isolated nutrients and optimization goals instead of actual eating. Turns out, counting grams isn\u2019t the same as eating a vegetable.<\/p>\n For all the hype, the fundamentals of fiber haven\u2019t changed.<\/em><\/p>\n For all the powders, gummies and gut-health rituals online, the least glamorous version of fiber may also be the most effective. Hanway recommends starting with whole-food sources first\u2014nonstarchy vegetables, berries and small amounts of properly prepared legumes. \u201cThese provide fiber, as well as water and other nutrients, which makes them easier to digest than more concentrated supplements.\u201d<\/p>\n Left to right: MiraLAX ($14 for 14 doses); Benefiber ($10 for 38 servings); Liquid Salad by Liquid+ ($70 for 28 pouches)<\/em><\/p>\n That doesn\u2019t mean supplements are off the table entirely. \u201cIf you\u2019re adding a supplement, increase gradually\u2014your gut needs time to adjust,\u201d Hanway says. \u201cStart with 5 to 10 grams additional per day and assess your tolerance before increasing further.\u201d Her biggest piece of advice has less to do with fiber than with patience\u2014the one thing the algorithm has never been good at selling.<\/p>\n The internet, in other words, turned fiber into a personality trait. Unfortunately for the algorithm, the science still points back to the vegetables. Grandma, once again, was right.<\/p>\n<\/div>\nThe Fiber Economy<\/h2>\n
