Savoury-snack shoppers comparing pack sizes
If you prefer something crunchy before training, stated serving sizes can help you judge how many portions you would use from a bag.
Who is this for?
People exercising after a missed meal
If you are considering a snack 60–90 minutes before exercise, check whether the whole snack—not just the chips—fits University College London Hospitals NHS Foundation Trust’s guidance to include carbohydrate and protein with minimal fat.
Shoppers checking dietary labels and allergens
Check the exact flavour and current pack. A maize-based chip, an explicit gluten-free label and a precautionary allergen statement tell you different things.
What should you check?
Start with the portion you would use, then check its nutrition and the exact pack’s dietary information.
| Priority | What to check | Your needs |
|---|---|---|
| Pack and portion | Compare the bag’s weight with its stated serving size. Decide whether individual packs or a larger bag better suit the portions you intend to use. | I want a portion I can identify without treating a whole sharing bag as one snack. |
| Snack timing | For 60–90 minutes before exercise, University College London Hospitals NHS Foundation Trust advises a snack with carbohydrate, protein and minimal fat. Consider the whole snack, not the chips in isolation. | If I have missed a meal, I want to check whether chips alone fit what I need before training. |
| Nutrition per serving | Read carbohydrate, fat and protein for the stated portion, rather than comparing unlike serving sizes. Sainsbury’s lists 19.4g carbohydrate and 6.3g fat per 30g of Stamford Street Co. Tortilla Chips; Tesco lists 15.8g and 5.8g respectively per 25g of its Lightly Salted Tortilla Chips. | A portion that looks small in the bag may still contain a noticeable amount of fat, so I want to check the figures for the amount I plan to eat. |
| Dietary information | Read the current pack’s ingredients, dietary claims, allergen declaration and any precautionary statement for the exact flavour. | I need to distinguish an explicitly gluten-free product from another maize-based chip, and check flavoured varieties for milk or other relevant allergens. |
Common buying mistakes
-
Assuming carbohydrate makes chips a complete pre-workout snack
University College London Hospitals NHS Foundation Trust advises carbohydrate, protein and minimal fat for a snack 60–90 minutes before exercise. The stated plain-chip portions also contain fat, so carbohydrate alone does not settle the choice.
Check the nutrition for your intended portion and consider the other foods in the snack if you are eating at that interval.
-
Assuming every corn chip has the same allergen profile
Marks & Spencer lists milk ingredients in M&S Cool Tortillas, while the Waitrose listing for Doritos Dip or Load Salted carries precautionary statements for cereals containing gluten, milk, soya and wheat.
Read the ingredients, allergen declaration and any ‘may contain’ statement on the current pack of the exact product and flavour.
-
Choosing a sharing bag without planning the portions
A bag intended for several servings does not tell you how much you will eat on one occasion.
Check the stated grams per serving before opening it, and follow the pack’s instructions for storing the remainder.

Eat Real Sea Salt Multiseed Tortillas 160g
This 160g sea-salted multiseed bag is an option if you prefer that flavour and format. For a snack shortly before exercise, check the current pack’s nutrition per serving, particularly fat and protein, alongside what else you plan to eat.

Doritos Chilli Heatwave 5 x 30g

Frequently asked questions
Are tortilla chips enough on their own before a workout?
Do not assume they meet the snack guidance for 60–90 minutes before exercise. University College London Hospitals NHS Foundation Trust advises carbohydrate, protein and minimal fat for that interval; check the chips’ nutrition per serving and the rest of the snack against those elements.
How can I compare portions across different bags?
Compare the bag weight with its stated serving size, rather than assuming each bag represents the same number of snacks. Sainsbury’s gives a 30g serving for Stamford Street Co. Tortilla Chips, while Tesco gives a 25g serving for its Lightly Salted Tortilla Chips; use the serving size on the pack you choose when reading its nutrition.
Does corn-based mean gluten-free or dairy-free?
No: the ingredients and claims differ by product and flavour. Marks & Spencer labels M&S Lightly Salted Tortillas gluten free, but its Cool Tortillas list milk ingredients; the Waitrose listing for Doritos Dip or Load Salted carries precautionary statements for cereals containing gluten, milk, soya and wheat. Check the current pack of the exact product.
What should I do with an opened sharing bag?
Follow the storage instructions on that bag and decide how you will divide the remaining servings. An opened sharing bag need not be eaten as a single pre-workout portion.
