The trend is marketing riding real need, not genuine food improvement. Sweet drinks with added fiber don't replace whole foods; patients feel satisfied but eat badly, harming their digestion. - Marcus DeVries
Food industry analyst and trend forecaster
Consumer demand for fiber came first; data shows 54% want high-fiber food. Convenient products teach the word and move money, though most operators use the trend minimally. - James Holbrook
Independent food writer and restaurant
Small convenient items open the door to dietary change, just as protein bars did. Marketing that teaches the word 'fiber' moves menus, even if adoption starts with one item.

What they debate
- Did PepsiCo's fiber launches prove consumer demand, or create it?
- Is 'fibermaxxing' on TikTok real health or dangerous trend-chasing?
- How much of the fiber boom is GLP-1 users needing satiety, how much marketing?
- Does the 54% consumer interest vs 22% operator adoption gap prove fiber is overhyped?
Transcript (beginning)
Hello and welcome. Fiber is big now. Is it real health or just marketing? Sarah, dietitian. Marcus, food trend expert. James, food writer.
Marcus, you track what brands sell. Is fiber real demand or PepsiCo making it real?
The demand came first. PepsiCo only followed it. Look, the numbers don't lie. Datassential says 54% of consumers want high-fiber food. PepsiCo is big, but not that big.
No, no, wait. Saying you want fiber in a survey is free. I went to three restaurants last week. Nobody ordered the bean bowl. Interest is not money.
Sarah, you see patients every day. What do they really need?
My patients need real food. Vegetables, whole grains, things you chew. Most people eat too little fiber, very little. A sweet drink with added fiber does not fix that. That is marketing.
A sweet drink people actually buy beats broccoli they never eat.
No, no, wait. That drink has very little fiber. People need thirty a day. A can will never do that. That's the gap right there.
Sarah, how do you see it?
That drink is not real food. It is sweet water with a little fiber. My patients drink it. They feel good. Then they eat the same bad food.
No can fixes everything, but people start small, and that counts.
Marcus, does starting small with a drink really move the needle?
No. Small does not count here. It sells a feeling, not fiber. And that is the real risk. People buy the can, feel done, and stop. Restaurants stay at 22% adoption.
