Cleanest Cereal at Walmart (2026)

Great Value, Cheerios, Magic Spoon, Three Wishes, Kashi and more, scored against The AisleScore Standard with the receipt for every deduction.
Standard v1.3, data as of 2026-10-20

Four cereals tie at a perfect 100: Three Wishes' Unsweetened Cereal, Kashi's Whole Grain Nuggets, Nature's Path Fruit Juice Corn Flakes Cereal, and Cascadian Farm's Purely O's. Walmart's own Great Value Toasted Oat Cereal and Magic Spoon's Fruity Protein Cereal both score 95, for different reasons. Cheerios scores 90 because sugar is its third ingredient.

What the receipts actually say

Three Wishes' Unsweetened Cereal lists four ingredients: chickpea, tapioca, pea protein and salt. There is no sugar and no flavoring for the rubric to catch.

Kashi's Whole Grain Nuggets and Nature's Path's Fruit Juice Corn Flakes Cereal both come through with zero flags. Nature's Path sweetens with grape and pear juice concentrate. Juice concentrate isn't on the Standard's list of sugar words, so the sugar-placement rule doesn't fire.

Cascadian Farm's Purely O's is whole grain oats and barley, wheat starch, malted barley extract and salt, with nothing flagged.

Great Value's Toasted Oat Cereal, Walmart's store brand, loses 5 points for length only: 14 ingredients, most of them added vitamins and minerals, crosses the more-than-10 line. None of its ingredients is a red flag under the Standard.

Magic Spoon's Fruity Protein Cereal loses 5 points for "natural flavor" on the label without saying what the flavor is. Its source record lists "Sweetener Blend" and "Oil Blend" without their contents, so rules that depend on those contents had nothing to check.

Cheerios loses 10 points because sugar is the third ingredient, after whole grain oats and corn starch. No other rule fired.

How we scored these

Every score here comes from The AisleScore Standard v1.3, applied the same way to store brands and national brands. What separates Cheerios from the four cereals at 100 is the sugar-in-the-first-three rule (−10). US labels list ingredients by weight, so a sugar or syrup near the top of the list is a rough signal of how much of the box it makes up. Great Value's deduction comes from the ingredient-count rule (over 10 ingredients: −5, then −2 per additional 5). Magic Spoon's comes from the natural-flavors rule, which deducts for "natural flavor(s)" that aren't identified.

Scores on this page are auto-scored from Open Food Facts data against The AisleScore Standard v1.3 and have not been hand-verified by AisleScore unless a product says "Hand-verified on [date]". Check the current package.

AisleScore doesn't track which stores carry each product, so check what your Walmart has on the shelf. A 10-point sugar deduction on a cereal you've eaten for years isn't a verdict on the brand. It's one line on a public receipt anyone can check. If you think we got a rule wrong, subscribe to the AisleScore newsletter and tell us.
