Late-night snackers watching portion calories
If you plan to have a bowl rather than the serving printed on the bag, compare kcal per 100g first. Then use the pack figures to work out what your intended portion means.
Who is this choice for?
Shoppers who want conventional corn chips
If maize tortilla chips are what you want for snacking or dipping, compare maize products with one another. A lentil-based tortilla-style snack may differ in flavour and texture.
Shoppers considering a lentil alternative
If you are open to a different base ingredient, compare the labelled calories, protein and fibre alongside flavour, salt and allergens. Those figures vary by product.
What should you compare?
Start with a like-for-like calorie comparison, then check the portion you would serve and any other label details that matter to you.
| Priority | What to check | Your needs |
|---|---|---|
| Portion calories | Compare kcal per 100g, then check kcal per stated serving and how many servings the pack contains. The British Nutrition Foundation explains that nutrition figures may be given per 100g, per portion or both. | I want to know what the amount I put in a bowl means, rather than choosing by a small printed serving alone. |
| Ingredient base | Check whether the snack is made from maize or lentils. Marks & Spencer lists 439 kcal, 24.8g protein and 6.5g fibre per 100g for its popped red-lentil tortillas; its Cantina maize chips list 466 kcal per 100g. | I might try a lentil-based snack, but I would not treat it as the same choice as a conventional corn chip. |
| Salt | Compare salt per 100g on the same basis as calories, then consider the portion. The listed figures include 0.75g for M&S popped lentil tortillas, 1.10g for M&S Cantina chips and 0.53g for Sainsbury’s Tortilla Chips. | Calories matter to me, but I also want to see how much salt my chosen portion contains. |
| Dietary suitability | Read the exact pack’s ingredients, allergen declaration and precautionary statements. The M&S lentil product says it is not suitable for people with sesame or soya allergy; Waitrose lists a may-contain-milk statement for Mister Free’d Chilli Tortilla Chips. | If I need to avoid an allergen, I cannot decide from the words “lentil”, “gluten-free” or “vegan” alone. |
What can make the label misleading?
-
Reading a serving claim as the calories in any portion
Waitrose lists Mister Free’d Chilli Tortilla Chips at 95 kcal per serving, but also at 475 kcal per 100g, with approximately seven portions in a 135g pack. A larger portion will not have the stated serving’s calorie figure.
Compare per 100g first, then portion out the amount you intend to eat rather than relying on the front-of-pack figure.
-
Assuming a dietary claim answers every label question
“Gluten-free” does not establish a product’s calorie figure or settle other allergen questions. Waitrose lists a may-contain-milk statement for the Mister Free’d chilli product, while the M&S lentil product carries sesame and soya allergy warnings.
Check the current pack’s nutrition table, ingredients and allergen statements for the exact variant you are buying.
-
Comparing calories but overlooking salt
Marks & Spencer lists 0.75g salt per 100g for its popped lentil tortillas and 1.10g for Cantina chips; Waitrose lists 1.20g for Mister Free’d Chilli Tortilla Chips. Their calorie and salt figures do not follow the same order.
Read both figures per 100g, then consider how much of the snack you expect to serve.
Which product ranges are relevant?
These references describe specific products or listings, not every snack made by each brand.
M&S
Marks & Spencer provides both a popped red-lentil tortilla-style snack and conventional Cantina maize tortilla chips for this comparison.
- The lentil product lists 439 kcal, 24.8g protein and 6.5g fibre per 100g; Cantina chips list 466 kcal per 100g.
- The lentil product is not a conventional corn chip and states that it is not suitable for people with sesame or soya allergy.
Mister Free’d
Waitrose lists Mister Free’d Chilli Tortilla Chips with both a per-serving claim and per-100g nutrition figures.
- The listing states 95 kcal per serving and 475 kcal per 100g, making the serving size important to the comparison.
- It lists 1.20g salt per 100g and a may-contain-milk statement.
Sainsbury’s
Sainsbury’s Tortilla Chips provide a conventional maize-chip reference for shoppers who want a plain snack.
- The product page lists 148 kcal per 30g serving, 494 kcal per 100g and 0.53g salt per 100g.
- Its listed calorie figure per 100g is higher than those of the specific M&S and Mister Free’d products discussed here.
Doritos
Tesco Groceries lists Doritos Cool Original and Chilli Heatwave sharing bags among its tortilla-chip products.
- Shoppers seeking those flavours can compare the nutrition panels of the exact variants they are considering.
- Do not infer a calorie figure for either variant from another tortilla-chip product.

Frequently asked questions
How do I compare packs with different serving sizes?
Start with kcal per 100g, then check whether the stated serving resembles the amount you would actually eat. Waitrose lists Mister Free’d Chilli Tortilla Chips at 95 kcal per serving and 475 kcal per 100g; Sainsbury’s lists its Tortilla Chips at 148 kcal per 30g serving and 494 kcal per 100g.
Is the lowest-calorie option here a conventional tortilla chip?
No. Of the specific products compared here, Marks & Spencer lists the lowest kcal-per-100g figure for its popped red-lentil tortillas, at 439 kcal; they are not conventional maize chips. Its Cantina maize tortilla chips list 466 kcal per 100g. Neither figure tells you the calories in your bowl without knowing the portion.
Should I check salt as well as calories?
Yes, if salt matters to your choice: the products’ figures differ on that measure too. For example, Sainsbury’s lists 0.53g salt and 494 kcal per 100g for its Tortilla Chips, while M&S Cantina chips list 1.10g salt and 466 kcal per 100g. Compare both figures on the same per-100g basis.
Do “gluten-free” or “vegan” claims settle allergy questions?
No. Check the exact pack’s ingredients and allergen statements for the substance you need to avoid. Waitrose lists a may-contain-milk statement for Mister Free’d Chilli Tortilla Chips, and M&S states that its popped red-lentil tortillas are not suitable for people with sesame or soya allergy.
