People counting calories
Compare the calories on the pack with the amount you will serve. NHS Better Health notes that a manufacturer’s portion may differ from the amount you eat.
Who is this choice for?
People making nachos or serving dips
Think about the chips and everything served with them. A sharing bag also makes it worth deciding how many chips to put out before you start eating.
People open to a different type of chip
A lentil-based tortilla-style snack is an option if you do not need a conventional corn chip. Compare its calories on the same per-100g basis, then check its ingredients and allergen information.
What should you compare?
Start with the amount you expect to eat, then use the per-100g figures to compare products with different stated serving sizes.
| Priority | What to check | Your needs |
|---|---|---|
| Portion calories | Read kcal per stated serving and its weight. Compare that weight with the portion you intend to eat; NHS Better Health cautions that the two may differ. | I want to count the chips I actually put in my bowl, not assume the pack’s serving is my serving. |
| Energy per 100g | Use kcal per 100g for a like-for-like label comparison. For a UK ‘low calorie’ claim on solid food, Business Companion’s February 2025 guidance gives a limit of 40 kcal per 100g. | A lower figure than another chip would help me compare options, but I would not treat it as a ‘low calorie’ claim. |
| Type of chip | Check whether it is a corn tortilla chip or a lentil-based alternative. M&S lists 439 kcal per 100g for its popped red-lentil tortillas and 466 kcal per 100g for its Cantina corn chips; the products also differ in ingredients. | For nachos, I may want a conventional corn chip. For a snack on its own, I may be willing to try a different type. |
| Other label details | Compare fat and salt using the same serving or per-100g basis. Check the current ingredient and allergen information, particularly when changing chip type. | Calories matter to my choice, but I also want to know what is in the product and whether it suits my dietary requirements. |
| Pack and accompaniments | Check the pack weight and decide how much to serve. Count dips and nacho toppings separately from the chips. | A small bowl may be easier for me to plan than eating from a sharing bag; toppings will change the total for the dish. |
What can change the calorie count?

Confusing ‘lower calorie’ with ‘low calorie’
A product can have fewer calories than another chip without meeting the threshold for a ‘low calorie’ claim. Business Companion’s February 2025 guidance sets that threshold at 40 kcal per 100g for solid foods.
Compare kcal per 100g, then calculate the calories for the portion you intend to serve.
-
Counting one serving but eating more
A pack can contain several stated servings. NHS Better Health warns that the manufacturer’s portion may not match the amount you eat.
Serve your chosen amount in a bowl and use that amount, rather than the pack’s default serving, for your calculation.
-
Counting the chips but not the toppings
The nutrition panel for tortilla chips does not describe a finished plate of nachos or chips with dip.
Account for the amounts of chips, dips and toppings you use when planning the dish.
-
Choosing by descriptive wording alone
‘Lightly salted’ describes a flavour, not the calorie figure. The Sainsbury’s listing for Capsicana wholegrain corn tortilla chips gives 523 kcal per 100g, while M&S lists 439 kcal per 100g for a different, popped red-lentil product.
Compare the energy figures on the same basis and check ingredients and allergens before switching product type.
Brand and product references
These label figures describe the named products, not every chip made by each brand.
M&S
M&S lists both Cantina corn tortilla chips and popped red-lentil tortilla-style snacks.
- The M&S listings give 466 kcal per 100g for Cantina chips and 439 kcal per 100g for the smoked paprika popped red-lentil product.
- The lentil product is a different type of snack; check its sesame and soya suitability warnings if relevant.
Mission
Mission Salted Tortilla Chips are listed as a 500g pack of conventional chips.
- Tesco Groceries lists 478 kcal per 100g for this product.
- A 500g pack contains more than one portion, so decide how much to serve rather than counting the whole pack as a single snack.
Doritos
Doritos Lightly Salted is a conventional corn-chip reference for comparing stated portions with per-100g calories.
- Tesco Groceries lists 146 kcal per stated 30g serving and 487 kcal per 100g.
- ‘Lightly Salted’ does not describe the product’s calorie content.
Waitrose Essential
Essential Tortilla Chips Salted provide an example with a stated 25g serving.
- Waitrose & Partners lists 122 kcal per stated 25g serving and 489 kcal per 100g.
- The 25g figure applies only if that is the amount you eat.
Sainsbury’s
Sainsbury’s own-label Tortilla Chips 200g provide another corn-chip label for comparison.
- Sainsbury’s lists 149 kcal per stated 30g serving and 496 kcal per 100g.
- Compare the 30g serving with the amount you intend to eat before using its calorie figure.

Common questions
Are tortilla chips low calorie?
The named corn-chip examples here do not meet the threshold for a UK ‘low calorie’ claim: their listings give 466–496 kcal per 100g. Business Companion’s February 2025 guidance sets the threshold for solid foods at 40 kcal per 100g. You can still compare chips and choose an amount that fits the snack you have planned.
Should I compare calories per 100g or per serving?
Use per 100g to compare products and the serving figure to calculate the amount you plan to eat. NHS Better Health cautions that a manufacturer’s stated portion can differ from your own.
Does a lentil-based chip have fewer calories than corn tortilla chips?
It depends on the products compared. M&S lists 439 kcal per 100g for its smoked paprika popped red-lentil tortillas, compared with 466 kcal per 100g for its Cantina corn chips. The lentil product is not a plain corn chip, so also check whether its flavour, ingredients and allergen information suit you.
Does ‘lightly salted’ mean fewer calories?
No calorie comparison follows from that flavour description alone. Tesco Groceries lists Doritos Lightly Salted at 487 kcal per 100g; compare the nutrition figures of the particular products you are considering.
Should I check ingredients and allergens again?
Yes. Check the current product label before eating, especially when moving from corn chips to a different type of snack. The M&S popped red-lentil tortillas carry sesame and soya suitability warnings.
