Who needs to check what?

The relevant label details depend on the allergen you avoid; nutrition comparisons come afterwards.

Shoppers avoiding milk, wheat or gluten

Look for an exclusion that names your particular allergen. Tesco Groceries lists the checked Tesco Free From tortilla chips and onion maize rings as free from milk, wheat and gluten. Check the full current pack for any other allergens relevant to you.

Shoppers comparing fat as well as allergens

Screen each product for your allergens first, then compare fat per 100g. Tesco Groceries lists 22.9–23.9g per 100g across the three checked Free From products; Walkers lists 25g per 100g for Monster Munch Pickled Onion. These figures describe particular flavours, not entire brands or a formal reduced-fat claim.

Parents and carers buying familiar flavours

Check the exact flavour and pack rather than relying on a brand name. Walkers’ allergy information for the checked Wotsits, Monster Munch and Quavers flavours identifies different ingredients and precautionary statements.

What should you compare?

Start with the current pack’s ingredients and allergen advice. Once a product fits the required exclusions, use the same nutrition basis to compare it with other suitable options.

Priority What to check Your needs
Allergens Read the full ingredient list, the exact scope of any free-from claim and any relevant precautionary statement. Do not treat one named exclusion as covering every allergen. I need to know whether this particular flavour fits the allergens I avoid before its fat figure matters.
Fat comparison Compare fat in g per 100g, then check the amount per serving or pack. Tesco Groceries lists 22.9g for Free From Nacho Cheese Tortilla Chips, 23.1g for Cool Flavour Tortilla Chips and 23.9g for Onion Maize Snack Rings, each per 100g. Once I have suitable products to choose between, I want a like-for-like fat comparison rather than assuming a smaller packet has a lower-fat recipe.
Current pack Match the flavour, pack and label you are buying to the product information you used to make a shortlist. Check ingredients and allergy advice again before eating. An earlier purchase or an online listing is useful for narrowing my options, but I need the information on the pack in front of me.

Common shopping mistakes

  • Assuming “Free From” covers every allergen

    Tesco Groceries’ checked Free From listings name milk, wheat and gluten. Those exclusions alone do not answer a question about another allergen.

    Match every allergen you need to avoid against the exact product’s current ingredients and precautionary information.

  • Using pack size or “baked” as a fat comparison

    A per-pack figure depends on how much food is in the pack, so it does not show how two recipes compare on the same basis.

    Compare fat per 100g first, then check the serving or packet figure for the amount you expect to eat. Look for a stated comparison basis before treating “reduced fat” as a product claim.

  • Assuming familiar savoury flavours have similar allergens

    Walkers states that Wotsits Cheese contains milk, Monster Munch Pickled Onion includes ingredients from milk and soya, and Quavers Cheese contains barley, milk and wheat.

    Read the ingredient and allergy advice for the exact flavour, including any relevant “may contain” or factory-handling statement.

  • Relying on an earlier packet

    An earlier label describes the product you bought then, not necessarily the pack you are choosing now.

    Use online details to shortlist options, but make the final allergen check on the current physical pack.

Product lines to check

These examples refer to specific listed products and flavours; a brand name alone does not establish allergen suitability.

Tesco Free From

The checked Tesco Groceries listings include tortilla chips and onion maize rings.

  • Tesco Groceries labels the checked Cool Flavour and Nacho Cheese tortilla chips and Onion Maize Snack Rings as free from milk, wheat and gluten. It lists 22.9–23.9g fat per 100g across those three products.
  • These named exclusions do not establish suitability for every other allergen. Check the current pack for the one you need to avoid.

Wotsits

The checked Cheese flavour is a maize-based snack.

  • The product’s format gives shoppers looking for a puffed snack a distinct option to check.
  • Walkers states that Wotsits Cheese contains milk and is made in a factory handling wheat, gluten, barley, soya, celery and mustard.

Monster Munch

The checked Pickled Onion flavour is a maize-based savoury snack.

  • Walkers lists 25g fat per 100g for Pickled Onion, a figure that can be compared with other products on the same per-100g basis after allergen screening.
  • Walkers lists whey permeate from milk and hydrolysed soya protein among this flavour’s ingredients.

Quavers

The checked Cheese flavour is principally potato-starch based rather than a straightforward maize-snack alternative.

  • Walkers lists 30.8g fat per 100g for the checked Cheese flavour.
  • Walkers declares barley, milk and wheat in this product. Its ingredients and snack type both matter when comparing it with maize options.

Joybuy corn options

These corn products cover different eating formats: a crunchy Habanero multipack and two cooked-corn options. Check each current pack for the allergens you avoid before comparing nutrition information.

Love Corn Habanero 10 x 45g multipack

Love Corn Habanero 10 x 45g

This roasted, crunchy corn option comes as ten 45g packs. If nuts or peanuts are relevant to your allergy, check the current pack’s precautionary information before choosing it.

Nong Sao Sweet Corn 220g

Nong Sao Sweet Corn 220g

These cooked sweet corn kernels are a different choice from dry crisps or puffs. Check the current pack’s ingredients and allergen information, then compare its fat figure per 100g with other suitable products.

Nongsao Colorful Glutinous Corn 220g

Nongsao Colorful Glutinous Corn 220g

This cooked corn is not a dry tortilla chip or puff. Do not infer allergen suitability from “glutinous” in the name; check the current pack’s ingredients and allergen advice for your needs.

Questions about allergens and fat

Does a lower fat figure make a maize snack suitable for my allergy?

No. Fat is a nutrition measure; suitability for a particular allergy depends on the exact product’s ingredients and relevant precautionary information. Check those on the current pack before comparing fat.

Are Tesco Free From maize snacks suitable for every food allergy?

No. Tesco Groceries labels the checked tortilla chips and onion maize rings as free from milk, wheat and gluten. Those statements do not establish suitability for a different allergen, so check the full label of the product you are buying.

Can I use an online listing to check allergens?

Use it to shortlist products, then read the physical pack before eating. The pack lets you check the ingredients and allergy advice for the exact product you have.

What does “may contain” mean on a snack label?

It is precautionary allergen information about possible unintended presence, rather than a declaration that the allergen is an ingredient. The Food Standards Agency describes this as the purpose of precautionary allergen labelling; take a statement relevant to your allergy into account when checking the pack.
