Source: USDA FoodData Central, SR Legacy, March 2026.
One ounce of tortilla chips (28g) contains about 141 calories with 1.9g of protein, 19.1g of carbs, and 6.3g of fat. Per 100g, tortilla chips provide 497 calories, 6.6g of protein, 67.4g of carbs, and 22.3g of fat. They are one of the more calorie-dense snack foods available. The carbs come almost entirely from corn, with only 1.2g of sugar per 100g, meaning the carbs are primarily starch. Fiber is 4.7g per 100g, which is decent for a chip. The standout micronutrient is calcium at 104mg per 100g, which is higher than most snack foods due to the lime processing (nixtamalization) used to make corn tortillas. For anyone tracking their diet, tortilla chips are a snack that adds up fast: three or four handfuls can push 400 to 500 calories. A single weighed 28g serving is 141 calories, which is reasonable, but most people eat two to three servings without realizing it.

Health Benefits of Tortilla Chips
Tortilla chips do not offer meaningful health benefits compared to whole food alternatives, but they are not nutritionally empty either. The 4.7g of fiber per 100g is higher than most chip-style snacks, coming from the corn base. Fiber supports digestive health and contributes to fullness.
The 104mg of calcium per 100g is a genuine standout. Traditional tortilla chips are made from nixtamalized corn, a process that treats corn with an alkaline solution (lime). This process increases the bioavailability of calcium and niacin from the corn. A 1 oz serving provides about 30mg of calcium, which is roughly 3% of the daily target.
Tortilla chips contain 22.3g of fat per 100g, split across saturated (2.8g), monounsaturated (8.6g), and polyunsaturated (9.2g) fats. The fat composition is reasonably favorable since most of it is unsaturated, coming from the vegetable oil used in frying.
For practical fitness use, tortilla chips are best positioned as an occasional snack rather than a daily staple. Pairing a weighed single serving with salsa or guacamole and a protein source (like grilled chicken) makes a more balanced meal. The key is using a kitchen scale instead of eating straight from the bag, which almost always leads to eating two to three times the intended portion.
Dietary Considerations
Tortilla chips are naturally gluten-free (made from corn) but check labels for cross-contamination warnings if you have celiac disease. They are vegan and dairy-free. They are not keto-friendly due to their high carb content (67.4g per 100g). For weight loss, tortilla chips require strict portion control. At 497 calories per 100g, they are one of the more calorie-dense foods you can eat. Measure out a single 1 oz serving rather than eating from the bag. The sodium content (310mg per 100g) is moderate; a full 1 oz serving contributes about 88mg of sodium.
