Best Fiber Cereal: The 7 Best Fiber Cereals (Because Time Comes for Us All)

Eventually you grow up. You get a job. You settle down. You do errands on Saturday mornings instead of watching cartoons or sleeping in until noon. Your doctor tells you to incorporate more fiber in your diet. Fine, you say. And you trudge out to the grocery store to buy your high fiber cereal, longingly looking over at those colorful boxes full of marshmallows. 

So there you are, faced with a wall of cereal boxes touting high fiber. Should you just grab any one? No. Just because you’re eating responsibly doesn’t mean you can’t enjoy it. The Sporked team sat down with Good Mythical Morning writer, Kalyn French (@kamasemicolon), to taste through a slew of fiber cereals and find the best ones. We’re all very healthy now, thanks for asking. Here are the best ones we tasted both with and without milk.

Best of the Best

Cascadian Farm Organic Hearty Morning Fiber Cereal 
(10g of fiber per serving)

They don’t beat around the bush with the name. It says it all: It’s hearty. It’s for the morning. And it’s cereal. They do bury the lead on the bevy of textures and tastes you’ll find inside, though. Each box contains a mix of lightly sweet whole wheat flakes, nutty bran sticks (or “strands,” as the brand refers to them), and delightfully crunchy granola clusters. When I say crunchy, I mean crunchy. You could hear the crunch from across the room when someone took a bite. If you count on cereal to wake yourself up in the morning, the crunch alone will do it.

Best Nutty

Kashi Go Honey Almond Flax Crunch
(8g of fiber per serving)

A mix of (very big) multi-grain clusters, sliced almonds, and flax seeds, this texturally varied cereal has a wonderfully nutty flavor. You can go on a little adventure with your spoon, hunting for big chunks when you want something hearty or sifting for the almonds and smaller bites when you want to go easy on your mouth. It’s engaging, is what I’m saying. Even though honey is in the name of the cereal, it’s not very sweet and actually has a touch of salt to balance out the sweetness that is hovering around the edges. It embodies the Kashi motto that Kalyn came up with while we were tasting: “We go hiking. We’re special. We’re Kashi.”

Best Zero Added Sugar

Fiber One Cereal 
(18g of fiber per serving)

While Kalyn described this cereal as consisting of “tendrils,” it was shockingly good. The flavor is close to that of a Cheerio with just a hint of honeyed sweetness (even though there’s no sugar, somehow). The crunch is good, and you can rest assured that it will remain good thanks to the smart packaging. It’s a satisfying bowlful of cereal that packs a flavor punch above expectations and offers a huge daily serving of fiber. Plus, each box comes with two bags of cereal, so it stays crunchy and fresh longer. Brilliant!

Best Old School

Grape-Nuts 
(7g of fiber per serving)

“Holy cow this is crunchy,” Kalyn said as she was taking her first few bites. “Like eating cute baby rocks.” And I have to concur. This classic cereal is extremely crunchy. But that crunch evolves over time as the milk soaks into the tiny granules of whole grain wheat, wheat flour, and malted barley flour. The cereal begins to yield to your bite, revealing a flavor that’s distinctly malty. It tastes like you’re eating something nutritious. I won’t say this is the best intro to fiber cereal for those folks who have been eating sugary treats for breakfast their whole lives, but it’s a classic bowful that deserves its place in the ranking. It also happens to be a brilliant ice cream topper.

Best No Milk

Frosted Mini Wheats
(6-7g of fiber per serving)

You certainly can enjoy these sweet, wheaty squares with milk. When they reach that perfect point of saturation, when they’re heavy with milk but still retain their crunch, they are absolutely delightful. But they also happen to make for a great milk-free snack. Sporked’s own Jordan Myrick doesn’t take milk with her cereal and happily chows down on Frosted Mini Wheats—especially if they’re offered at a hotel breakfast buffet. And why wouldn’t you want breakfast to remind you of a getaway? They have that wonderful balance of wholesome nutrition and sugary indulgence that you look for in a cereal. Jordan’s only critique is that the frosting is only on one side. Kellogg’s, we’re waiting.

Best No Nonsense

Post Shredded Wheat 
(8g of fiber per serving)

If you’re not interested in any bells or whistles, and you really just want a fiber-packed cereal with a hearty texture, reach for the old reliable: Post Shredded Wheat. They hold milk very well and retain their crunch, so you don’t have to worry about a bowl full of mush after 10 minutes. The flavor is wheat-forward, which is what you should expect out of a product that bills itself as being wheat and only wheat. If you want to add berries or even a sprinkling of sugar, go for it. This is a blank canvas of texture on which you can play. Otherwise, enjoy your plain shredded wheat, you adult, you.

Best Gluten-Free

Poop Like a Champion Ultra Fiber Cereal
(22g of fiber per serving)

Let’s start with the positives: One serving contains 79% of your daily recommended fiber. Holy moly. The tiny, star-shaped cereal bites have an almost graham cracker-like texture. They’re light and airy with a hint of sweetness. They’re easy eating with a really pleasant flavor. Plus, they’re gluten-free. Great. Now a few critiques: They’re not cheap. They were nearly double the cost of a few of the other brands on this list. And then there’s the name. I don’t want to be labeled a “prude” but I like a little bit of mystery in my fiber cereal. Let’s not announce to the world (aka the checkout person) why I’m buying a particular cereal. But if you appreciate the edginess, then good on you. You’re cool.
