Kellogg's Froot Loops Cereal: Labelgrade C+ (66/100)
C+ 66 / 100 — Additive-heavy formulation (maltodextrin or corn syrup and artificial colors), high sodium per 100g, and substantial fiber.
🛒 Buy on Amazon →The short answer
Kellogg’s Froot Loops Cereal delivers 1.2g of protein and 78.5 calories per 1 Container (USDA FDC 2736037). Per 100g that’s 5.7g of protein; per oz, 1.6g. The Labelgrade is C+ (66 / 100): Additive-heavy formulation (maltodextrin or corn syrup and artificial colors), high sodium per 100g, and substantial fiber.
Why this Labelgrade
| Dimension | Grade | Score | Why |
|---|---|---|---|
| Protein density | C- | 59 / 100 | 5.7g per 100g — below the high-protein bar; not the right product for protein hunting |
| Ingredient quality | C+ | 65 / 100 | 25 ingredients; flagged maltodextrin or corn syrup + artificial colors |
| Saturated fat load | A- | 88 / 100 | 0.399g per serving (1.9g per 100g) — very low |
| Sodium load | D | 45 / 100 | 111mg per serving (150mg per oz) — meaningful per 100g |
| Sugar load | B- | 74 / 100 | 6.57g sugar (6.45g added) — moderate |
| Fiber | B- | 70 / 100 | 1.2g per serving — good |
| Overall | C+ | 66 / 100 | Weighted blend: protein 25% · ingredients 22% · saturated fat 18% · sodium 15% · sugar 12% · fiber 8% |
A word of caution reading this table: the sugar and fiber dimensions both score better than your gut says they should, and that’s an artifact of the tiny logged serving. Most boxed cereal is dessert-adjacent, and the grade tracks added sugar against whole-grain fiber — Froot Loops is squarely on the dessert end. It lands at C+ rather than lower mostly because the 21g single-serve cup keeps the absolute sugar number small and because added fibers prop up the fiber line. Scale to a real bowl and the picture gets less flattering.
The serving size is doing a lot of the work
This is the number that matters most for an honest read. The USDA logged this product as a 0.75 oz (21g) single-serve cup — the little variety-pack carton — and every figure on this page is scaled to that. It’s why the sugar reads as a moderate 6.45g and the calories as a slim 78.5: the portion is roughly a third of what many people actually pour. Per 100g, Froot Loops is about 31% sugar by weight. A normal kid-sized bowl (closer to 39g) lands near 12g of sugar; a generous adult bowl, more than that.
So when the sugar dimension scores a B- and the calories look low, read it as a function of the cup, not the cereal. The most honest single statistic here is the per-100g one: nearly a third sugar, with refined corn flour as the base and sugar as the second ingredient. None of the per-serving numbers are wrong — they’re just describing a deliberately small pour.
How it compares
| Product | Protein per serving | Per 100 g | Per oz | Calories |
|---|---|---|---|---|
| Kellogg’s Froot Loops Cereal (this product) | 1.2g | 5.7g | 1.6g | 78.5 |
| Kellogg’s Frosted Flakes Cereal | 3g | 5g | 1.4g | 220 |
| General Mills Cinnamon Toast Crunch Cereal | 2g | 4.9g | 1.4g | 170 |
| Post Honey Roasted Bunches Of Oats Cereal, Honey Roasted | 4g | 7g | 2g | 220 |
| Plain cooked chicken breast (benchmark) | — | 31g | 8.8g | ~165 |
No fruit, four dyes, and fiber that was added back
The name says “froot,” and the ingredient list is the place to check what that means. There is no fruit in Froot Loops — the flavor is “natural flavor,” and the colors that make the rings red, yellow, blue, and green are Red 40, Yellow 5, Blue 1, and Yellow 6, four synthetic dyes. That’s the main reason the ingredient-quality dimension scores only a C+: artificial colors plus maltodextrin and a hydrogenated-oil coating are exactly the kind of additives the grade penalizes.
The fiber line deserves the same scrutiny. The cereal does post 1.2g of fiber, but it isn’t coming from whole grain in any meaningful amount — the base is a corn flour blend that’s partly degerminated (refined), and the fiber on the label traces to added oat fiber and soluble corn fiber listed down in the 2%-or-less section. That’s isolated fiber stirred back in, not the intact bran-and-germ fiber you get from an oat or bran cereal. It still counts on a label, but it’s a manufactured number, not a sign of a whole-grain bowl. The honest summary: this is a brightly-colored sugar cereal with the fiber engineered back in, and the grade reflects that.

Frequently Asked Questions
Is Kellogg's Froot Loops a healthy cereal?
No — it's a dessert-style kids' cereal, and the grade says so honestly: C+. It's built on refined corn flour and sugar (the first two ingredients) and colored with Red 40, Yellow 5, Blue 1, and Yellow 6. There's no real fruit despite the name. It's fortified with vitamins and isn't dangerous in a normal portion, but it's a sweet treat that happens to be eaten at breakfast, not a nutritious one. If you want a cereal that's actually doing nutritional work, this isn't it.
Why does Froot Loops score a C+ (66/100)?
A few things keep it from falling further: the per-serving sugar looks moderate (a B-) and the added fibers post a passable fiber number (a B-), both partly because the logged serving is tiny. What drags it down is the ingredient quality (C+ — flagged for maltodextrin/corn syrup-type sweeteners and four artificial dyes) and a sodium load that reads high per 100g (a D). Net: a sugar-and-dye kids' cereal that lands in the C range, above the lowest-graded bowls only because the small serving keeps its absolute sugar number in check.
Why does the sugar look low — is Froot Loops actually low in sugar?
No. The 6.45g of added sugar per serving looks modest only because the serving the USDA logged is a small 0.75 oz (21g) single-serve cup. Per 100g, Froot Loops is roughly 31% sugar by weight. Pour a normal kid-sized bowl (closer to 39g) and you're at ~12g of sugar; a big bowl, more. Sugar is the second ingredient. Read the per-100g figure, not the tiny-cup serving, if you want the honest picture.
What's the serving size, and does it include milk?
The numbers are for dry cereal only — milk is not included — and the serving is a small 0.75 oz (21g) single-serve cup (the variety-pack size), not a standard ~1 cup bowl. A real bowl is roughly 2x these figures. Adding 1/2 cup of milk brings about 4g of protein and ~100mg of calcium plus its own calories and sugar; for a cereal this low in protein (1.2g dry), the milk supplies most of the protein in the bowl.
Is there a better-graded cereal to pick instead?
Easily. Almost any whole-grain bowl out-grades it: [Kellogg's Raisin Bran](/kelloggs-raisin-bran-cereal-202-5-lbr) (B) brings real bran fiber, and [Honey Nut Cheerios](/general-mills-sales-inc-honey-nut-cheerios-cereal) (B-) at least starts from whole oats. If the appeal is a sweet, colorful bowl for a kid, the engineered higher-protein cereals (Magic Spoon, Catalina Crunch) hit a similar flavor target with far more protein and fiber and no artificial dyes — at a higher price.
