Tasting a bunch of high fiber cereal in search of the best high fiber cereal is not the sexiest activity—even when your job is tasting groceries. But I did it for you—twice—because we all need fiber. I don’t care how young or old you are, dietary fiber is an important nutrient. Not only does it help you in commode-related activities, but it also helps lower cholesterol and maintain healthy blood sugar levels. But does that mean you have to settle for a bowlful of cardboard in the morning? Flavorful high fiber cereals exist in the world. And I set out to find them—for you and for me.
Over the course of two taste tests, I tried 24 fiber rich cereals. The only requirement to make the tasting line-up was that a serving contain at least 6g of fiber—though more was preferable. I judged these high fiber cereals not only on how healthful they purported to be, but also on their texture (you gotta have crunch to stand up to milk) and flavor (I know high fiber cereal is probably not going to taste like Cocoa Puffs but it should still be enjoyable to nosh).
Whether you’re looking for the most fiber rich cereals that can actually be stomached, the best high fiber cereal for kiddos, or simply a good fiber cereal that happens to satisfy your chocolate cravings, we’ve got recommendations for you. Here’s our updated list of the best fiber cereals to buy.

- Poop Like a Champion Ultra Fiber Cereal
(22g of fiber per serving) -
Let’s start with the positives about this extremely high fiber cereal: One serving contains 79% of your daily recommended fiber. Holy moly. That alone earns this cereal a place on our ranking of the best high fiber cereal. 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 high fiber cereal. Let’s not announce to the world (aka the checkout person) why I’m buying a particular cereal. But if you appreciate a high fiber cereal that puts it all on front street, then good on you. You’re cool. And this is the best cereal with fiber for you.

- Post Shredded Wheat
(8g of fiber per serving) -
If you’re not interested in any bells or whistles, and you really just want a high fiber cereal with a hearty texture, then Post Shredded Wheat is the best high fiber cereal for you. The squares hold milk very well and retain their crunch, so you don’t have to worry about a bowl full of mush after a few 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. Because this is a high fiber low sugar cereal—there’s literally 0g of sugar in a 47g serving. So, you can afford to add some sweetness, if that’s what you want. Otherwise, enjoy your plain shredded wheat, you adult, you.

- 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 their 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? If you’re not just eating cereal for fiber but also for pleasure, then Frosted Mini Wheats are here for you. 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.

- Grape-Nuts
(7g of fiber per serving) -
One taster likened eating this classic high fiber cereal to eating “cute baby rocks.” And I have to concur. It 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 fiber cereal for those folks who have been eating sugary treats for breakfast their whole lives, but it’s a classic bowlful that deserves its place in the ranking. It also happens to be a brilliant ice cream topper.

- Puffins Original Cereal
(6g of fiber per serving) -
My kids love these dang things. They’re light and sweet and puffy. And they taste a bit like Honey Nut Cheerios in a puff form. Yes, there’s sugar in the mix, but just 6g per serving, which, in the grand scheme of kids’ cereals, is pretty darn good. Plus, there’s 11g of whole grain in every serving, too. My kiddos will happily chow down on this fiber cereal dry—straight out of a snack trapper. But they’re good with milk, too. They don’t sog up immediately and the sweetness in the cereal complements the sweetness in the milk. This is the best fiber cereal to buy if you’re looking for something for both kids and grown-ups.

- Fiber One Cereal
(18g of fiber per serving) -
Even though some tasters found these high fiber cereal “tendrils” a bit off putting in terms of their appearance, they taste great. The flavor is close to that of a Cheerio with just a hint of honeyed sweetness (even though this is another high fiber low sugar cereal). The crunch is good, and you can rest assured that it will remain good thanks to the smart packaging. Each box comes with two bags of cereal, so it stays crunchy and fresh longer. Brilliant! It’s a satisfying bowlful of high fiber cereal that packs a flavor punch above expectations and offers a huge daily serving of fiber.

- 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 high fiber 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. If you’re a Honey Bunches of Oats devotee looking to add more fiber to your diet, this is the best cereal for fiber to try.

- Kashi Go Chocolate Crunch
(6g of fiber per serving) -
This high fiber cereal tastes like brownie batter. The knots of oats and puffed whole grains are extremely crunchy, and they finish a little bitter—like actual cocoa powder. This is grown-up chocolate cereal, for sure. Not only because of the flavor, but because of the 6g of fiber per serving and the 10g of protein per serving. Plus, this chocolaty fiber cereal is vegan. If you’re looking for a chocolate fix in the morning but are too responsible for Cocoa Pebbles, this is the best fiber cereal to buy.

- 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 fiber 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. This continues to be the best high fiber cereal.
