Which cereal has the most fiber?
The most fiber per serving on this list is 11 g, in Julian Bakery's Vanilla Cinnamon Cluster Pro Granola — a 1/3-cup (30 g) serving covering 39% of the 28 g Daily Value, for 100 calories and 0 g of sugar. Among the familiar supermarket boxes, Kellogg's Raisin Bran Original leads at 7 g of fiber per 1-cup serving, with Frosted Mini-Wheats and Malt-O-Meal Frosted Mini Spooners just behind at 6 g.
Every one of the twelve picks clears 4 g of fiber a serving, and each gram is read off that product's own Nutrition Facts panel rather than a taste test. Fiber and sugar are separate questions, though: this list is ordered by how many shoppers buy and rate each cereal, so it includes boxes that are high in both. Sugar runs from 0 g to 20 g a serving across these picks, and both numbers show on every one.

How this list is built
Every product comes from a large database of branded grocery items: popular, well rated, and available to buy. This list holds high-fiber cereal only, ordered by popularity. Each item is checked so its protein, fat, and carbohydrate add up to its stated calories. MyPlate.food is independent and not affiliated with any retailer or the USDA.
What makes a good high-fiber cereal?
Several grams of fiber per serving from real food sources, with a rating that confirms it's still enjoyable to eat.
How are these ranked, and why is each one here?
We rank by popularity — aggregated shopper review counts and ratings — among products that pass a validation check (their macros must reconcile with their calories). Each pick carries a short reason it earned its spot, and links to a full product page with its Nutrition Facts, ingredients, and an independent analysis.
Can I buy these on Amazon?
Yes. Every pick is a recognizable national brand carried on Amazon — the product name, photo, and "Shop" button open an Amazon search for it. As an Amazon Associate we may earn a commission, which never affects the ranking.
Where does this data come from?
A proprietary database of about 1.87 million branded grocery products from major US retailers, with nutrition facts, ingredients, ratings, and dietary tags. We validate and rank the data rather than republishing it raw, and we're independent — not affiliated with any retailer or the USDA.
What is the highest-fiber breakfast cereal here?
A 1/3-cup (30 g) serving of Julian Bakery Vanilla Cinnamon Cluster Pro Granola carries the most fiber at 11 g — 39% of the 28 g Daily Value — for 100 calories. Kellogg's Raisin Bran Original is the highest-fiber mainstream box on the list at 7 g per 1-cup serving, and Frosted Mini-Wheats and Malt-O-Meal Frosted Mini Spooners follow at 6 g.
How can I get 25 to 30 g of fiber a day?
US Nutrition Facts labels use a 28 g Daily Value for dietary fiber, and the % Daily Value printed on every product here is figured against it. One 11 g serving covers 39% of a day; a 1-cup serving of Raisin Bran covers 25%. Breakfast is a head start rather than the whole total, so the % Daily Value on each pick is the number to add up across the day.
Which cereals here are high in fiber and low in sugar at the same time?
Two of the twelve. Julian Bakery Vanilla Cinnamon Cluster Pro Granola shows 11 g of fiber and 0 g of sugar per 1/3 cup (30 g), and Original Cheerios shows 4 g of fiber and 2 g of sugar per 1 1/2 cups (39 g). The rest carry more — Frosted Mini-Wheats 12 g of sugar a serving, the Special K cup 20 g — because this list is ordered by how many shoppers buy and rate each cereal, not by sugar. Both numbers show on every pick.
Which cereal here has the most fiber and protein together?
