The 10 Most Sugary Cereals & The 10 Least


How Sweet Are Your Mornings?

Well all know cereal isn't the healthiest breakfast choice. But behind all the mascots and marshmallows lies a massive gap in sugar content. Some cereals are tame enough for the health-conscious types, but others are outrageously sweet, with levels that rival donuts! Let's take a closer look at just sugary your breakfast staple is. Before exploring the more balanced picks, let's focus on the sugary options that can actually substitute for dessert. Sugar content is based on a 1-cup serving of each cereal.

1. Golden Crisp: 21g Sugar

Golden Crisp is essentially puffed wheat coated in syrup, with sugar making up more than half the cereal. Once known as Sugar Crisp, it’s still sold as an “energy” cereal, but its candy-like sugar level tells an entirely different story.

2. Honey Smacks: 18g Sugar

With over 56% sugar in every bowl, Honey Smacks packs more sweetness than a glazed donut. Nutritionists have long flagged it as one of the worst cereals for kids. At one point, Kellogg’s even dropped “Honey” from the name to downplay the sugar content.

3. Cap’n Crunch Crunch Berries: 16g Sugar

This cereal hits hard with artificial “berry” flavors and zero real fruit. Introduced in 1967, the ultra-crunchy texture holds up in milk, while the artificial fruity taste hides just how indulgent each spoonful really is. It’s anything but a balanced start.

4. Froot Loops: 12g Sugar

Despite being called fruity, Froot Loops contains no actual fruit—just 12 grams of sugar per serving and identically flavored loops in multiple colors. The bright design keeps kids coming back, even if the taste stays the same, no matter the hue.

5. Trix: 12g Sugar

Trix debuted in 1954 with only three colors and has since evolved into two styles: puffballs and classic loops. Each serving equals the sugar in three cookies, and this makes this kid-favorite a deceptively sweet start to any morning.

6. Apple Jacks: 12g Sugar

Apple Jacks originally featured only green and orange loops and barely contains any of the fruit it’s named after. It leans hard into artificial flavors and bold colors. Despite health concerns, the cereal consistently ranks as a childhood favorite.

7. Reese’s Puffs: 12g Sugar

This chocolate-and-peanut-butter cereal draws direct inspiration from Reese’s, blending dessert vibes with breakfast tradition. With its unmistakable branding crossover, it sneaks candy-level indulgence into every bowl and continues to fool your morning routine into a sweet treat.

8. Lucky Charms: 12g Sugar

Don’t let the whole grains fool you—this cereal hides sugary marshmallow bits that have evolved in shape since its 1964 debut. The charm lies in those eye-catching, colorful additions that mask its sweetness beneath a nostalgic glow that’s stuck around for decades.

9. Cocoa Pebbles: 12g Sugar

Introduced in 1971 and starring Fred Flintstone and Barney Rubble, it still draws fans with nostalgic Saturday morning cartoon vibes. However, Cocoa Pebbles turns milk into a chocolatey treat with its dessert-like flavor and high sugar content.

10. Cookie Crisp: 12g Sugar

Shaped like mini chocolate chip cookies, this cereal sparked controversy with a mascot who literally stole cookies for breakfast. Not only is this cereal loaded with sugar, but it also contains a high amount of sodium, two key traits of heavily processed foods.

In contrast, the following options focus on whole grains, fiber, and minimal sweetness.

1. Fiber One Original: 0g Sugar

Fiber One Original stands out with zero sugar, low fat, and a dense structure that keeps hunger at bay. Every spoonful delivers function first and is favored by those seeking steady nutrition. The high-fiber formula also supports cholesterol and blood sugar goals.

2. Shredded Wheat: 0g Sugar

With nothing added—not even salt or sugar—Shredded Wheat focuses entirely on whole wheat nutrition. The firm texture holds up in milk, while the high fiber content provides steady energy. More than 120 years later, this classic still appeals to health-minded eaters.

3. Uncle Sam Cereal: 1g Sugar

Uncle Sam Cereal combines whole wheat with flaxseed to pack in fiber and omega-3s. Fans of clean eating also appreciate the cereal’s simplicity, honest ingredients, and ability to stay relevant in a modern pantry. Additionally, since 1908, the recipe has remained mostly unchanged.

4. Cheerios: 1g Sugar

Whole grain oats form the heart of this cereal, which helped it earn FDA approval and a reputation for heart health. It’s one of the most trusted names in low-sugar breakfast options and is consistently favored by families looking for clean and simple choices.

6. Kix: 3g Sugar

Its “Kid-tested, parent-approved” slogan gave Kix instant appeal—and decades later, the cereal still holds its ground. Corn-based and gently sweet, it offers a flavor simple enough for toddlers yet satisfying enough for older kids and parents looking to keep sugar in check.

7. Corn Flakes: 3g Sugar

Originally created to ease indigestion, Corn Flakes introduced a plain, toasted corn option to breakfast tables. The simple crunch is often favored as it pairs beautifully with fruit for natural sweetness. Plus, the high availability and affordability also help keep this cereal as a lasting staple.

8. Special K Original: 4g Sugar

First launched in 1955, this cereal quickly won over calorie-conscious eaters. Its light flakes made from rice and wheat work just as well in snack recipes as they do in a bowl. Today, it still holds a strong spot among nutritious low-sugar cereal options.

9. Wheaties: 5g Sugar

Wheaties has claimed its place as the “Breakfast of Champions” for nearly 100 years. Whole grain-based and rich in B vitamins, it keeps sugar minimal while gaining credibility from elite athlete endorsements that continue to shape its legacy on the shelf.

10. Grape-Nuts: 5g Sugar

Fiber and protein give this cereal its edge, even though it contains neither grapes nor nuts—just wheat and barley. Often mixed into yogurt or trail blends, it’s been marketed for both digestive support and sustained energy, making it a surprisingly versatile option.
