We Graded Every Tortilla A–F. Corn Beats Flour, Cleanly.

The tortilla aisle splits on one line: corn versus flour. We ran the most popular tortillas and wraps through the same 6-dimension Labelgrade, and the divide is stark. Corn tortillas win clean — Guerrero is corn, lime, and water, almost no sodium, and naturally gluten-free, the kind of short label that scores well without trying. Mission’s fiber-engineered Carb Balance wrap wins a different way, leaning on 9g of added fiber. And the refined white-flour tortillas — the soft taco staples — trail, because white flour brings little fiber and more sodium. The clean answer to ‘are tortillas healthy’ falls right out of the grades: corn beats whole-grain beats white flour.

The verdict

We graded 5 tortillas A–F: the category averages 69/100 (C+), from 81 (B+) at the top down to 63 (C) at the bottom.

Corn runs away with it: Guerrero White Corn Tortillas at B+ (81); refined Mission Flour Tortillas came last at C (63), separated on fiber, ingredients and sodium rather than calories.

Pros and cons come straight from each product’s own label. A dimension is listed only when its sub-score is decisive (78 or above for a pro, 62 or below for a con), so a merely-average number never gets sold as a strength. Every figure is per labeled serving — full panels on each product page.

How we graded these

Each product is scored on six dimensions — protein density, ingredient quality, added sugar, sodium, fiber, and saturated fat — combined into a 0–100 score and a letter grade. Every number comes from the product’s own label, verified against USDA FoodData Central. The grade is absolute (relative to all packaged foods), which is why a whole category can land in the same band. See the full methodology. Last graded 2026-06-04.

Frequently Asked Questions

Which tortilla scored best?

Guerrero White Corn Tortillas took the top at B+ — a three-ingredient label of corn, lime, and water, with almost no sodium and naturally gluten-free. Mission’s Carb Balance Flour wrap followed at B-, winning a different way on 9g of added fiber. See the ranked table above for the full order and each one’s weakest dimension.

Why did Mission Flour Tortillas score lowest?

Refined white-flour tortillas bring little fiber and more sodium than corn — and fiber, ingredient quality, and sodium are three of our six dimensions — so they trail at C. It isn’t a fail; it’s just out-scored by the corn tortillas and the fiber-engineered wrap above it. The grade reflects what’s on the label, not the format you’re used to.

Are tortillas healthy?

It depends on what they’re made of, which is the whole point of the spread: corn beats whole-grain beats white flour. Corn tortillas are a clean, short-label, naturally gluten-free choice; the fiber-engineered wraps win on fiber; refined white-flour tortillas score lower on fiber and sodium. A B-to-C grade means "a solid staple, just pick corn or high-fiber when you can."

How is the grade calculated?

Six dimensions — protein density, ingredient quality, added sugar, sodium, fiber, and saturated fat — into a 0–100 score and a letter grade, from each product’s own label, verified against USDA data. See our methodology page.
