Protein had a good run. It moved into bread, tortillas, cookies, chips, and donuts. Now the food industry is shopping for its next big nutrient, and PepsiCo's CEO told investors in October 2025 that "fiber will be the next protein." Fiber is showing up in more snacks, drinks, and front-of-package claims, and the underlying need is real. The question is what happens when the food industry gets hold of it.

Why fiber, and why now

For years, protein was the nutrient that could make almost anything sound better for you. Fiber is getting the same treatment, helped along by "fibermaxxing," the TikTok trend of deliberately eating more of it, and Gen Z's focus on gut health. One food research firm found 52% of consumers were interested in trying it after hearing about it, and 42% think a "high fiber" label means healthier food. Whole Foods' 2026 forecast expects more fiber callouts on packaging, and Frito-Lay opened the year with SmartFood FiberPop and SunChips Fiber. When a nutrient moves from the nutrition label to the front of the package, the trend has arrived.

The gap is real

Fiber differs from most wellness trends because most Americans don't get enough. Only about 5% of American adults meet the recommended intake: 25 grams a day for women under 50 and 38 for men, with an average of around 17 grams. In a 2025 survey, no one said they didn't want or need more fiber, and the top barriers were not knowing which foods have it, the cost, and the taste. 

That creates a genuine opportunity. If a snack helps someone get more fiber without overhauling their diet, that's useful. But there's a difference between making fiber easier to get and making a product look healthy because it contains fiber, and a number on the front of a package is much easier to market than what it means.

The catch

Not all fiber is the same, and the front of the package doesn't tell you which kind you're getting. Beans, oats, whole grains, fruit and vegetables deliver fiber alongside other nutrients. Packaged products may use added fibers like inulin to push up the number on the label. A 2022 Stanford study found that inulin didn't seem to lower blood sugar and cholesterol the way psyllium husk and the fiber in many whole grains do, and responses varied from person to person. Stanford's experts say whole foods are still the best source. 

There's a practical side, too. Raising your intake too fast can overwhelm your gut, so it's better to increase it gradually. If you're planning to turn every high-fiber product on the shelf into a personal challenge, your digestive system may have feedback.

How to shop the trend

Before a fiber-forward product goes in the cart, we'd check four things:

Where the fiber comes from. Whole foods first. If a packaged product gets most of its fiber from added ingredients, treat it as a boost, not a foundation.

How much you're actually getting. Check the grams per serving and the serving size, then compare it to the 25 to 38 gram daily target. A big number on the front is less impressive when the serving is smaller than what you'd eat.

What else is in it. Fiber doesn't cancel out the rest of the label. Check the sugar and ingredients, as you would with any snack.

How fast you're ramping up. Add it gradually, and drink more water as you go.

From this month's drops

Cob, one of our October drops, makes popped sorghum, a whole grain that pops like popcorn. A 27-gram serving has 3 grams of fiber, and it comes from the grain itself, not an added ingredient, which is the whole-foods-first rule in snack form. Three grams is roughly a tenth of the 25 to 38 gram daily target, so it's a solid contribution but not a full answer. As with anything here, check the serving size against how much you'd actually eat.

The Edit

Fiber deserves the attention. Most of us could use more, and making fiber-rich foods easier to find and enjoy is a good thing.

But you don't need a fiber-enriched chip or a prebiotic soda to discover a bean, an oat, or an apple. If a fiber-forward snack tastes good and helps you get more fiber, great. Just don't let the claim on the front of the package do the thinking for you. The next big thing in food might be something we've needed all along, and the trick is not letting the packaging convince us it's new.
