Choose a potato crisp grab bag for crunch or flavour, not as the protein part of a snack: the Walkers, Seabrook and Tyrrells bags described below provide 1.4g to 2.8g protein per bag, according to their product information. If protein is your priority, choose a separate food that fits your protein target; check the crisp bag’s portion size, salt and allergens if you want it alongside.
If the snack itself needs to contribute protein, compare the amount per whole bag with your target. The Walkers, Seabrook and Tyrrells potato-crisp examples here provide 1.4g to 2.8g per bag, according to their product information.
If another food supplies the protein you want, a grab bag can be a separate choice for crunch and flavour. Check the precise bag size, flavour, salt and allergen information before choosing.
If a clinician or dietitian has set your protein target, use that advice when planning snacks. Cambridge University Hospitals NHS Foundation Trust notes that protein needs can vary with age, disease status and activity.
Start with protein for the portion you will eat, then check the other label details that matter to your choice.
| Priority | What to check | Your needs |
|---|---|---|
| Protein contribution | Read protein per whole bag, not just per 100g. The Food Standards Agency describes the UK high-protein claim criterion as at least 20% of a food’s energy coming from protein; a gram figure alone does not establish that. | If this snack needs to contribute to my protein target, I need to judge the portion I will actually eat rather than assume that savoury crisps are protein-rich. |
| Portion size | Compare the exact pack size and its protein and energy figures together. Walkers Ready Salted lists 1.6g protein and 130 kcal per 25g bag; Tyrrells Lightly Sea Salted lists 2.8g and 208 kcal per 40g bag. | A larger bag may give me more protein grams, but I also want to know what else changes with the larger portion. |
| Salt | Read salt per bag for the exact flavour. Walkers lists 0.34g per 25g Ready Salted bag and Tyrrells lists 0.26g per 40g Lightly Sea Salted bag; these are different products and portions. NHS guidance sets a general adult maximum of 6g salt a day. | If I eat crisps regularly, I want the bag’s salt figure alongside the rest of the food I eat that day. |
| Ingredients and allergens | Check the selected flavour’s ingredients, allergen statement and any product-specific dietary declaration. Do not rely on a flavour name or a statement about the wider brand range. | For a vegetarian, vegan, gluten-free or allergen-avoidance requirement, I need to know whether this particular bag fits it. |
Walkers Ready Salted, Seabrook Sea Salted and Tyrrells Lightly Sea Salted list 1.4g to 2.8g protein per bag in the cited product information. Choosing one for its savoury flavour is a different decision from choosing a food to supply protein.
Choose the food that meets your protein requirement separately, then add a crisp bag if you want one.
A 40g bag and a 25g bag do not represent the same amount of food. More protein grams in the larger bag do not, by themselves, make it a protein-focused choice.
Compare protein, energy and salt for the whole bag of the exact size you intend to eat.
Salt information belongs to the particular product and portion, not the brand name alone. NHS guidance gives a general adult maximum of 6g salt a day.
Read the salt value on your chosen flavour and consider it alongside the rest of your day’s food.
A brand’s statement about its range does not replace the selected product’s ingredients and allergen information.
Check the current bag for the dietary declaration and any allergen or cross-contact warnings relevant to you.
These examples help you compare formats and labels; they do not establish that every flavour has the same nutrition information.
Walkers publishes per-bag information for its 25g Ready Salted potato crisps.
Tyrrells lists a 40g Lightly Sea Salted potato-crisp bag and publishes separate information for its lentil crisps.
The Kettle Chips shop lists cases containing 18 individual 40g bags.
A Seabrook variety pack listed by ASDA contains 25g bags in different flavours.
Pipers describes a range of potato-crisp flavours available through selected retailers and other outlets.
REAL describes its range as vegetarian and gluten free.
These options are alternatives to potato-crisp grab bags: lentil cakes in a 100g pack and a multipack of bars. Neither is a single potato-crisp grab bag, so check the portion and protein information if you are choosing a snack around a protein target.

These lentil cakes offer a crisp-style alternative when a potato-crisp bag is not essential. The pack contains 100g rather than a single grab-bag portion; check the label for the amount of protein in the portion you plan to take.

This bar is a different snack format if protein matters more to you than having potato crisps. The pack contains four 40g bars; check the per-bar protein and allergen information for the one you would eat.
Do not assume that it does. The Food Standards Agency describes the UK high-protein claim criterion as at least 20% of a food’s energy coming from protein. The cited product information lists 1.6g protein in a 25g Walkers Ready Salted bag, 1.4g in a 25g Seabrook Sea Salted bag and 2.8g in a 40g Tyrrells Lightly Sea Salted bag; use the exact product label rather than treating a larger gram figure as a high-protein claim.
Start with protein per whole bag or serving and the amount you intend to eat. If a clinician or dietitian has given you a protein target, use that personalised advice when deciding what role, if any, crisps have alongside other foods.
A larger bag can contain more protein grams without making protein its main contribution. Tyrrells lists 2.8g protein and 208 kcal for its 40g Lightly Sea Salted bag, so compare both figures for the full portion rather than choosing by bag size alone.
Read the salt figure for the exact flavour and whole bag. Walkers lists 0.34g salt in its 25g Ready Salted bag; NHS guidance sets a general adult maximum of 6g salt per day, which also includes salt from other foods.
Follow the protein target and food choices given by your clinician or dietitian rather than using potato crisps in place of foods in that plan. Cambridge University Hospitals NHS Foundation Trust notes that protein requirements can vary with age, disease status and activity.
