Key findings
- 1Nixtamalization is a 3,500-year-old process that improves corn's nutritional profile; it is traditional processing, not ultra-processing
- 2Plain tortilla chips with three ingredients (corn, oil, salt) are among the simplest snack foods
- 3Flavored varieties like Doritos list far more ingredients and are far more processed, despite starting from the same corn base
Why is Tortilla Chips Level 3 on average?
Authentic tortilla chips start with masa; corn that has been nixtamalized (soaked in calcium hydroxide solution), an ancient Mesoamerican technique dating back 3,500 years that releases niacin and improves the corn's nutritional profile. The masa is pressed into tortillas, cut into triangles, and fried in oil with salt. This is a remarkably simple snack. The processing escalation begins with flavored varieties: nacho cheese, ranch, and lime-flavored chips add maltodextrin (a highly processed starch used as a flavor carrier), MSG or autolyzed yeast extract, artificial colors, and whey protein concentrate. A plain tortilla chip has three ingredients; heavily flavored chips list far more. In our analysis, tortilla chips average 12.1 ingredients and a Processing Score of 5.6, which is Level 3.

Frequently asked questions
Are Tostitos ultra-processed?
Original Tostitos list corn, vegetable oil, and salt, a short list of recognizable ingredients. Tostitos Hint of Lime and other flavored varieties add citric acid, sugar, and natural flavors, and heavily seasoned varieties add more. Each Tostitos product page shows its own score.
Are tortilla chips healthier than potato chips?
From a processing standpoint, simple tortilla chips and simple potato chips are similarly processed when made with just their base ingredient, oil, and salt. The health difference depends more on the specific oils, salt content, and whether flavorings are added.
What makes Doritos more processed than regular tortilla chips?
Doritos start with the same corn base but add a long list of ingredients including maltodextrin, MSG, artificial colors (Red 40, Yellow 6), and multiple cheese powders. The seasoning blend is a manufactured formulation applied to a simple chip.
