Meanwhile dietary fibre is on track to be 2026’s online trend of choice: ingest as much as possible and you’ll be less hungry and more regular, say online advocates who wave bowls of chia seeds and oats at the camera.
Brands have taken note : if you can buy it, there’s probably a protein-boosted version of it – even the sugariest cereals are touting their high protein content.
And blue chip companies like PepsiCo and Nestle along with newer firms like Olipop are jumping on the bandwagon, highlighting the fibre content in prebiotic sodas or chips.
“I think fibre will be the next protein,” said PepsiCo chief executive Ramon Laguarta in an earnings call late last year.
A survey from the consulting firm Bain & Company showed nearly half of US consumers are trying to eat more protein.
Across the United States, Europe and Asia, it’s Gen Z and Millennial consumers primarily driving the fad, according to the survey.
The same goes for fibre: according to London’s GlobalData, 40 percent of Gen Z and 45 percent of Millennials reported they’re trying to improve their gut health .
More not always best
Nutritionists say there are grains of truth to the fibre craze.
Andrea Glenn, an assistant professor of nutrition at New York University, called the movement surrounding fibre a “pretty tame wellness trend compared to the other things out there.”
Samantha Snashall, a registered dietitian at Ohio State University’s medical center, said protein has been “the special child” in recent years – and fibre has been “pretty undervalued.”
“I’m glad it’s having some light shed on it.”
But those experts along with Arch Mainous — a professor of community health and family medicine at the University of Florida, who has researched the use of social media in health communication – said more isn’t always best, especially when it comes to protein.
Mainous said eating according to the recommended daily values is one thing – but “if you say one’s good, five’s better? I’m not really for that.”
He voiced concern that people are putting too much stock in the one-size-fits-all health advice of influencers.
It’s part of a broader trend that has resulted in a “lack of trust in health experts,” he said – a “I’ll do my own research” mentality that has also been fueled by the likes of US Health Secretary Robert F. Kennedy Jr, who has spread anti-vaccine misinformation for years.
Few influencers are trained scientists, Mainous said, and many have brand deals or agendas of their own, including products to sell.
No ‘silver bullet’
So what’s an eater to do?
First, talk to your physician, Mainous said.
As a general guideline, the American Heart Association says that for many people, a day that includes a combination of foods like a glass of milk, a cup of yoghurt, a cup of cooked lentils, and a piece of cooked lean meat or fish about the size of a deck of cards will be in the ballpark of the average daily protein target.

Fibre-wise, Glenn said 25-38 grams depending on age and sex is a good goal.
High-fibre foods – such as beans, fruits, vegetables, nuts and whole grains like oats or quinoa – are linked to lower rates of certain cancers, and can help keep cholesterol and blood sugar in check.
Generally, Glenn said, people can eat some whole grains or fruit at breakfast, and then should try to fill half their plates with vegetables at lunch and dinner.
With that visualisation, “you’ll easily hit that target without needing to meticulously count how much fibre you’re consuming,” she told AFP.
But if you’re not currently eating much fibre – most people aren’t -“maxxing” is not a good course, Snashall warned.
Shake things up overnight and “your GI system is going to have a strong reaction,” she said. “Slow and steady wins the race.”
And Glenn noted that powders and supplements can’t serve as a replacement for whole, real foods.
Perhaps most importantly, no nutrient is a cure-all – those “fibre-rich” chips probably won’t change your life.
“I think it’s important to never view these things as a silver bullet to all your problems,” she said.
