For years, January was defined by what you couldn't eat. We’ve seen the rise and fall of juice cleanses and extreme low-carb diets. However, search data shows that in 2026, consumers are moving toward additive nutrition. Instead of cutting out food groups, people are looking to "max out" their nutrient intake—specifically fiber.
The Gut-Brain Connection
The surge in interest isn't just about digestion. We are becoming more aware of the gut-brain axis. New research and viral health discussions have highlighted how a high-fiber diet supports the microbiome, which in turn influences everything from mood and mental clarity to skin health and immunity.
Top High-Fiber Foods Trending Right Now
It’s not just about Metamucil anymore. The 2026 fiber trend is culinary and diverse. According to recent search spikes, these specific foods are leading the charge:
Passion Fruit: Boasting one of the highest fiber contents of any fruit, it has seen a 400% increase in search interest as a "hero" ingredient.
Kohlrabi & Celeriac: These "forgotten" vegetables are making a massive comeback as people look for hearty, fiber-rich alternatives to potatoes.
Chia Seeds: A staple of the "gut-health" movement, particularly in the form of overnight puddings.
Cruciferous Slaws: Pre-cut blends of kale, broccoli stalks, and cabbage are becoming the go-to "convenience health" purchase.
How to Increase Your "Plant Points"
A popular concept within the fibermaxxing community is the idea of "Plant Points." The goal is to eat 30 different types of plants per week to diversify your microbiome. Here’s how to hit that goal without feeling overwhelmed:
1. Focus on Simple Swaps
You don’t need to overhaul your entire pantry. Start by swapping white rice for farro or quinoa, or adding a handful of lentils to your usual pasta sauce. These small changes can easily add 5–10 grams of fiber to your day.
2. Embrace the "Value-Added" Section
Let's be real: peeling a celeriac or chopping a head of kale is a chore. One of the biggest retail trends this year is value-added produce. Buying pre-washed, pre-cut high-fiber veggies makes it much more likely that you’ll actually eat them on a busy Tuesday night.
3. Don't Forget Hydration
A common mistake when "fibermaxxing" is forgetting to increase water intake. Fiber needs water to move through your system effectively. If you're upping your bean and grain game, make sure you're carrying a water bottle with you.
The Verdict: Is it Just a Fad?
Unlike many "crash" trends, the focus on fiber is rooted in sound nutritional science. Whether it’s driven by the popularity of GLP-1 friendly diets or a general desire for better gut health, the shift toward eating more whole, plant-based foods is a win for longevity.
The beauty of this trend is its accessibility. You don’t need an expensive subscription or a specialized gym—you just need to look a little closer at the produce aisle.
