Shoppers comparing calories
If you want tortilla-chip crunch while paying attention to calories, use kcal per 100g to compare products and the portion or pack figure to judge what you intend to eat.
Who is this choice for?
People choosing between snack packs and sharing bags
A 48g bag and a 175–200g sharing bag answer different needs. Check how many servings the larger bag lists rather than treating its per-serving figure as a whole-pack figure.
Shoppers checking ingredients and dietary suitability
Protein or lentil-based tortilla-style snacks may be worth comparing alongside maize chips. Check the exact variant’s ingredients and allergens before accepting it or a substitution.
What should you compare?
Start with kcal per 100g for a like-for-like comparison, then use pack weight and serving information to assess the amount you expect to eat.
| Priority | What to check | Your needs |
|---|---|---|
| Energy comparison | Compare kcal per 100g across the exact products. Ocado lists Doritos Protein Sweet Chilli Chipotle at 406 kcal per 100g; Marks & Spencer lists its popped red-lentil tortillas at 439 kcal per 100g. | I want to compare tortilla-style options on the same weight basis, rather than judging them by pack size or a product name. |
| Portion and pack | Check both the listed serving weight and kcal for the amount you plan to eat. Tesco lists 123 kcal per 25g serving of its Lightly Salted Tortilla Chips; Sainsbury’s lists 149 kcal per 30g serving of its Tortilla Chips. | For one snack, I would rather know the calories in my planned portion or whole small bag than rely on a sharing bag’s serving figure. |
| Protein and fibre | Read these figures alongside energy, using the same per-100g or per-pack basis. Marks & Spencer lists 24.8g protein and 6.5g fibre per 100g for its popped red-lentil tortillas. | If protein or fibre matters to my choice, I still want to see how the tortilla-style snack compares for calories. |
| Allergens and delivery | Check the exact flavour’s ingredients and allergen statement, your substitution settings and availability for your delivery address. Recheck the label on the pack received. | An alternative flavour or substituted item needs to meet my ingredient and dietary requirements too. |
What can catch you out?
Assuming a product name tells you its calories
“Lightly salted”, “protein” and “popped” describe different aspects of a snack; none is a substitute for its energy figure.
Compare kcal per 100g on the nutrition panels, then check the portion you expect to eat.
Comparing unlike serving sizes
Tesco’s stated serving is 25g, while Sainsbury’s stated serving is 30g. Their serving-calorie figures therefore cover different amounts of food.
Use the per-100g figures first, then calculate your choice around the portion or pack you plan to use.
Choosing a tortilla-style alternative for one feature alone
Ocado lists the 48g Doritos Protein bag at 195 kcal for the whole pack, while Marks & Spencer lists protein and fibre values per 100g for its red-lentil tortillas. Those figures answer different questions.
Compare energy, pack weight and the nutrients that matter to you on clearly labelled bases.
Inferring allergens from the main ingredient
A maize or lentil base does not establish the allergen profile of every flavour. The M&S red-lentil product is identified as unsuitable for people with sesame or soya allergy.
Review the exact item and any proposed substitution, then check the delivered pack’s label.

Common questions
Does a smaller bag always contain fewer calories?
No: pack weight alone does not tell you its energy content. Compare kcal per 100g, then check kcal for the whole bag or the portion you plan to eat. Ocado lists its 48g Doritos Protein bag at 195 kcal for the whole pack.
Do popped, protein or lentil tortilla snacks necessarily have fewer calories?
No. Check each product’s nutrition panel rather than relying on those descriptions. Ocado lists Doritos Protein Sweet Chilli Chipotle at 406 kcal per 100g, and Marks & Spencer lists its popped red-lentil tortillas at 439 kcal per 100g; their pack sizes and other nutrition figures differ.
Why compare per 100g as well as per serving?
Per 100g puts different products on the same weight basis. A serving figure helps with the amount you intend to eat, but stated servings can differ: Tesco uses 25g for its Lightly Salted Tortilla Chips, while Sainsbury’s uses 30g for its Tortilla Chips.
What should I check before confirming delivery?
Check the exact item’s pack weight, nutrition, ingredients and allergens, along with substitution settings and availability for your address. Review the label on the delivered pack, particularly if an ingredient or allergen matters to your choice.
