Glucose impact
Very Low
Glucose risk
Tortilla chips are made from corn flour — moderate GI (~60). A typical serving delivers 19g of carbs, but realistic portions (60-90g) deliver 40-55g of fast carbs.
Processing level
Plain salted tortilla chips (corn, oil, salt) are NOVA 3. Flavoured varieties (Doritos, etc.) are NOVA 4 due to maltodextrin, flavour enhancers, and artificial colours.

What to watch for when shopping
Tortilla chips alone are NOVA 4 (corn, vegetable oil, flavourings, salt). A plate of loaded nachos with cheese, salsa, and sour cream can reach 800-1000 kcal. Plain tortilla chips are 480+ kcal per 100g. For a lighter option, bake your own from corn tortillas (NOVA 1-2) and top with fresh salsa.
