For coeliac shopping, check gluten status before comparing fat: Simply Roasted says its roasted range is gluten free and contains 50% less fat than traditional fried crisps, while M&S labels its Reduced Fat Ready Salted Crisps gluten free and states 30% less fat. Popchips Sea Salt & Vinegar is another gluten-free option, with 13g fat per 100g according to Popchips UK, though it is a popped snack rather than a conventional sliced potato crisp. Check the current pack in each case; a reduced-fat claim does not resolve the gluten warnings on the Walkers Oven Baked Sea Salt and Tyrrells Lentil Crisps Sour Cream & Onion products described by their manufacturers.
Start with the exact product’s gluten labelling, then assess its fat claim or nutrition panel. Coeliac UK notes that seasoning and manufacturing cross-contact can affect whether potato crisps are suitable for a gluten-free diet.
Compare fat per 100g before looking at pack or serving figures: M&S lists a 40g Reduced Fat Ready Salted pack, whereas Popchips UK gives nutrition for a 23g serving of Sea Salt & Vinegar.
Check the individual flavour rather than relying on the brand or the fact that a snack contains potato. Walkers and Tyrrells list gluten-related precautionary warnings on the specific lower-fat products discussed here.
Filter by the exact pack’s gluten information, then compare fat on the same per-100g basis. Use serving figures to plan a portion, not to replace a like-for-like comparison.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten labelling | Read the exact flavour’s gluten-free claim, ingredients and precautionary allergen statements on the current pack. Coeliac UK warns that seasoning and cross-contact can affect crisps. | I need to establish whether this particular pack fits my gluten-free shopping requirements before considering its fat content. |
| Fat comparison | Check what any percentage reduction is compared with, then read fat per 100g where available. Simply Roasted’s 50% comparison is a range-level manufacturer claim against traditional fried crisps; M&S states 30% less fat for its Reduced Fat Ready Salted Crisps and lists 21.3g per 100g. | A reduced-fat claim matters to me, but I want to know its comparison basis rather than assume different products’ percentages mean the same thing. |
| Snack type | Check whether the product is a conventional potato crisp or a popped snack. Popchips UK describes Sea Salt & Vinegar as a popped potato snack and lists 13g fat per 100g; its page does not make a percentage reduced-fat comparison. | I am willing to consider a different snack format if its ingredients, gluten labelling and nutrition suit what I am choosing. |
| Portion size | Compare per-100g figures first, then check the amount in the pack or stated serving. M&S lists a 40g pack; Popchips UK lists a 23g serving for Sea Salt & Vinegar. | For a lunchbox or a single snack, I want to understand the amount I might eat, not mistake a smaller serving for a lower fat concentration. |
Walkers Oven Baked Sea Salt and Tyrrells Lentil Crisps Sour Cream & Onion make lower-fat comparisons, but their published allergen advice includes gluten-related “may contain” warnings.
Read the current pack’s gluten claim and precautionary statements before using its fat claim to make a choice.
Coeliac UK explains that flavourings containing wheat flour and manufacturing cross-contact can make some crisps unsuitable for a gluten-free diet.
Check ingredients and allergen advice for the exact flavour, even if another flavour from the brand has been suitable.
A figure for M&S’s 40g pack cannot be compared directly with a figure for Popchips’ 23g serving.
Use fat per 100g for the product comparison, then read the pack or serving figure for the amount you intend to eat.
M&S warns that its product information may change, including ingredients, nutrition and allergen details.
Use listings to narrow your options, then make the final decision using the current pack.
These references concern the named ranges or products, not every crisp made by each brand. A gluten-free claim and a reduced-fat claim answer different questions.
A roasted-crisp range to consider when both gluten labelling and a comparative fat claim matter.
Its Reduced Fat Ready Salted Crisps offer a conventional potato-crisp option with both claims stated on the product page.
Sea Salt & Vinegar is a popped potato snack for shoppers open to a different format from sliced potato crisps.
A reference when stated gluten-free status matters more than finding a reduced-fat claim.
A hand-cooked crisp range to assess for gluten labelling before comparing nutrition by flavour.
Its Oven Baked Sea Salt example shows why a lower-fat claim cannot stand in for gluten advice.
The Sour Cream & Onion lentil crisp is another product whose fat claim must be considered separately from its allergen advice.
This lentil-chip option offers an alternative to potato crisps. For coeliac shopping, check the current pack’s gluten labelling and fat panel before deciding whether it meets both requirements.

For a lentil-chip alternative to potato crisps, check the current pack’s gluten statement and fat per 100g against your coeliac-shopping and reduced-fat requirements. The listed pack size is 95g.
Not automatically. Coeliac UK says seasoning can contain wheat flour and manufacturing cross-contact can lead to a “may contain gluten” statement, so check the exact pack’s ingredients and allergen advice.
No: although Walkers states that this flavour has 50% less fat than regular potato crisps, its published allergen advice says it may contain wheat, gluten and barley. Check the current pack rather than relying on the fat claim.
Their lower-fat claim does not make this flavour a coeliac-shopping choice. Tyrrells states that it has 30% less fat than standard potato crisps on average, but its allergen advice says it may contain gluten.
Use fat per 100g to compare products, then check the pack or serving size for the amount you plan to eat. M&S lists a 40g pack for its Reduced Fat Ready Salted Crisps, while Popchips UK gives a 23g serving for Sea Salt & Vinegar.
Yes. M&S warns that ingredients, nutrition and allergen information can change; for a coeliac-shopping decision, use the current pack’s gluten and precautionary allergen statements.
