For a top-up shop, choose tortilla chips by the amount you expect to eat, not by a lightly salted name. The Tesco, Sainsbury's and Waitrose listings and Doritos product information put the examples considered here at 478–494 kcal per 100g; compare portions, then check fat, salt and any dip you plan to add.
If a sharing bag is more than you intend to eat, look at the labelled serving before choosing a pack. Tesco and Waitrose list 25g servings at 123 and 122 kcal respectively; the Sainsbury's and Doritos Lightly Salted listings give 148 and 146 kcal for 30g.
Decide how much dip or topping you will use alongside the chips. A chip's serving figure covers the chips, not everything added to them.
Read the label on the exact flavour and pack you buy. The Tesco listing for Doritos Lightly Salted, for example, carries a precautionary statement about other ingredients handled at its factory.
Start with a portion you would actually eat, use per-100g figures for comparing products, then check the rest of the label and the pack format.
| Priority | What to check | Your needs |
|---|---|---|
| Calories | Compare kcal per 100g on the same basis. Then read each pack's kcal per serving and its serving weight: the Tesco, Sainsbury's and Waitrose listings and Doritos product information give 25g and 30g examples ranging from 122 to 148 kcal. | I want to know what the amount I plan to eat contributes, rather than choosing by a low-calorie impression from the pack name. |
| Fat and salt | Check the fat and salt figures as well as calories. GOV.UK explains that traffic-light labels indicate whether fat, saturates, sugars and salt are high, medium or low. | A slightly different calorie figure is not my only consideration; I want to see the other label information before choosing. |
| Pack format | Check the number of servings and whether the pack is for sharing or contains separate bags. Sainsbury's lists approximately six servings in its 200g bag; Waitrose lists eight in its 200g bag and also lists a Doritos 5 x 30g multipack. | For a quick snack on my own, separate packs or a portion set aside from a sharing bag may make the amount easier to plan. |
| Ingredients and allergens | Read the current pack's ingredient list and allergen information for the exact flavour. Do not assume that different tortilla chips have the same recipe or precautionary statements. | If an ingredient or allergen matters to me, I need the information for the bag I am taking home. |
The name describes the flavour, not a calorie comparison. The Tesco, Sainsbury's and Waitrose plain or lightly salted examples and Doritos Lightly Salted range from 487 to 494 kcal per 100g; Doritos lists Chilli Heatwave at 478 kcal per 100g.
Use the per-100g nutrition figures to compare the exact products, then check the serving you expect to eat.
A 25g serving and a 30g serving are different amounts of food. Tesco and Waitrose list 122–123 kcal for 25g, while the Sainsbury's and Doritos examples list 143–148 kcal for 30g.
Compare products per 100g first; use the serving figure to plan your own portion.
The calorie figure for a serving of chips does not include salsa, guacamole or nacho toppings. Calories alone also do not show the pack's fat and salt information.
Check the chip label and decide how much dip or topping to use alongside your portion.
Recipes and label information can change. The Tesco listing for Doritos Lightly Salted says its factory also handles milk, wheat, gluten, barley, soya, celery and mustard.
Check the ingredients and allergen statement on the physical pack, particularly when trying a different flavour.
These label examples help with comparison; each figure applies to the named product and serving, not every tortilla chip from that brand.

Not necessarily. The Tesco, Sainsbury's and Waitrose plain or lightly salted examples and Doritos Lightly Salted range from 487 to 494 kcal per 100g, while Doritos UK lists Chilli Heatwave at 478 kcal per 100g. Compare the exact packs per 100g rather than judging by the flavour name.
Check the kcal and weight of a labelled serving against the amount you expect to eat. Then look at the number of servings in the bag and its fat and salt information; GOV.UK explains that traffic-light labels show whether these and other listed nutrients are high, medium or low.
Use the pack's serving weight as a starting point, put that amount in a bowl and set the rest aside. Sainsbury's lists approximately six servings in its 200g tortilla-chip bag, while Waitrose lists eight in its 200g bag; check your chosen pack rather than assuming the bag is one serving.
Yes. Check the ingredients and allergen statement on the physical pack each time, because recipes and label information can change. For example, Tesco's Doritos Lightly Salted listing says the product is made in a factory that also handles milk, wheat, gluten, barley, soya, celery and mustard; that statement applies to the named product, not every Doritos pack.
Consider whether another format suits the occasion. NHS snack guidance gives examples including plain rice cakes or crackers with lower-fat cheese and vegetable sticks with low-fat hummus. None is automatically lower in calories than your chosen portion of tortilla chips, so compare the exact products and any additions.
