Start with the specific allergen, then compare fat content: a low-fat rice cake is not necessarily suitable for someone with a food allergy. Kallo lightly salted products carry may-contain warnings for milk, sesame and soya, while Sainsbury's plain rice cakes are labelled unsuitable for customers with a milk allergy because of manufacturing methods. For a solid food, the low-fat labelling condition is no more than 3 g of fat per 100 g; check the current pack's ingredients and allergen advice as well as its nutrition panel.
The relevant allergen determines whether a rice cake is worth considering; its fat content cannot answer that question.
Read precautionary statements alongside the ingredients. Kallo's lightly salted rice cakes may contain all three allergens, and Sainsbury's plain and lightly salted rice cakes are labelled unsuitable for customers with a milk allergy because of manufacturing methods.
Compare fat per 100 g across packs, then make a separate allergen check. Listed plain or lightly salted examples from Kallo, Sainsbury's and M&S have different ingredients and allergy information, even where their fat figures meet the low-fat condition.
Confirm which allergens the person needs to avoid before choosing a flavour or relying on a vegan label. The Food Standards Agency advises that vegan labelling is not a substitute for checking allergen and cross-contact information.
Check allergen suitability first, compare fat on the same per-100 g basis, and repeat both checks if you change flavour or pack.
| Priority | What to check | Your needs |
|---|---|---|
| Allergens and cross-contact | Match both the ingredients and any may-contain statement to the specific allergy. A vegan or gluten-free label does not replace this check; the Food Standards Agency says precautionary allergen labelling communicates a possible cross-contact risk. | I need to know whether the particular pack fits the allergy I'm shopping for. In a Food Standards Agency-commissioned online survey conducted in December 2023 among adults in England, Wales and Northern Ireland, 53% of respondents with an animal-origin food hypersensitivity, and 50% of those who shopped for someone with one, knew before the survey that vegan products might still be unsuitable because of cross-contact. |
| Comparable fat figures | Compare fat per 100 g: nutrition-claims rules published by legislation.gov.uk set no more than 3 g per 100 g as the low-fat condition for solid foods. A calorie figure per cake does not establish that a product is low fat or reduced fat. | I want to compare packs on the same basis, rather than judge them by cake size. In the Food Standards Agency and Ipsos Northern Ireland's 2024 Making Food Better Tracker, 49% of 611 Northern Ireland respondents reported actively using traffic-light labelling when shopping for food; that measures label use, not a preference for rice cakes. |
| Flavour and coating | Read each variant's ingredient list and fat figure separately. M&S Milk Chocolate Rice Cakes contain milk and soya and list 20.4 g fat per 100 g; the Kallo Marmite rice cakes listed by Asda declare gluten-containing cereals and celery. | If I switch from plain to chocolate-coated or savoury rice cakes, I need to check that exact flavour rather than carry over my decision from another pack. |
| The pack you receive | Check the physical pack before eating, particularly after a substitution. Sainsbury's, Asda and M&S advise that online ingredients or allergy information can change. | When a different pack arrives or I pick another size in store, I want its current label to confirm the ingredients and allergen advice. |
These labels do not rule out cross-contact with a different allergen. Kallo's gluten-free, lightly salted rice cakes carry may-contain warnings for milk, sesame and soya.
Check the ingredients and precautionary statement for the exact product and allergen, even when another claim on the front of the pack looks relevant.
The low-fat condition for a solid food is based on fat per 100 g. Calories per cake measure something different, while a claim about a reduction calls for a comparison.
Use the per-100 g nutrition panel to compare fat, and check what any reduction claim is comparing. Assess allergen information separately.
Coatings and flavourings change what is in the product. M&S Milk Chocolate Rice Cakes contain milk and soya; the Kallo Marmite rice cakes listed by Asda contain gluten-containing cereals and celery.
Repeat the ingredient, allergen and nutrition checks when choosing a different flavour or coated variety.
Retailers advise that ingredients and allergy information can change, so a previously checked listing may not describe the pack in hand.
Read the label on the pack you receive or pick up, including when your original choice has been substituted.
These examples show why nutrition figures and allergen statements must be checked for individual products, not assumed to apply across a brand or retailer.
Kallo lists organic lightly salted and unsalted wholegrain rice cakes with less than 3% fat.
Its plain rice cakes list 2.4 g fat per 100 g; its lightly salted wholegrain version lists 2.7 g.
M&S lists lightly salted rice cakes containing wholegrain brown rice and salt, with 2.5 g fat per 100 g.
Asda's listings illustrate how allergen advice varies between flavoured rice cakes.
Tesco lists Kallo Lightly Salted Wholegrain Low Fat Rice Cakes with 2.8 g fat per 100 g.
Snack a Jacks describes its range using a per-snack calorie figure.
These options cover a lightly salted wholegrain rice cake and a savoury Marmite-flavoured rice cake. Their different ingredient profiles make the exact pack label important when shopping for an allergy.

A lightly salted wholegrain option for comparing plain rice cakes. Kallo lists its organic lightly salted variety as containing less than 3% fat, but warns that it may contain milk, sesame and soya. Check the allergen statement on the pack you receive.

A savoury flavoured option that calls for a different allergen check from a plain rice cake. Asda's listing for Kallo Marmite rice cakes declares barley, celery, oats, rye and wheat, and says they may contain milk, sesame and soya. Check the ingredients, precautionary statement and fat per 100 g on the exact pack before choosing it.
No. The Food Standards Agency advises against using vegan labelling as a substitute for allergen information because cross-contact can still matter. Sainsbury's plain and lightly salted rice cakes, for example, are described as prepared to a vegan recipe but unsuitable for customers with a milk allergy because of manufacturing methods.
For solid foods, the low-fat labelling condition is no more than 3 g of fat per 100 g under the nutrition-claims rules published by legislation.gov.uk. Compare that figure across products; calories per cake do not establish whether a rice cake meets the fat condition.
Use the page to narrow your choices, then read the physical pack before eating. Sainsbury's, Asda and M&S advise that online ingredients or allergy information can change.
No. A gluten-free description does not address every other allergen or cross-contact risk. Tesco's listing describes Kallo's lightly salted low-fat rice cakes as gluten free while warning that they may contain milk, sesame and soya.
Treat it as relevant to your decision, not as a guarantee that the allergen is absent. The Food Standards Agency explains that precautionary allergen labelling communicates a possible cross-contact risk; check the exact pack and follow the risk-management advice applicable to the person you are shopping for.
