Parents looking for more protein in the snack
If a rice-cake-style snack needs to make a meaningful protein contribution, compare its label with a plain rice cake on the same per-100g basis.
Who is this choice for?
Families managing food allergens
A gluten-free label does not answer every allergen question. Check the exact pack’s ingredients and precautionary warnings alongside the child’s school arrangements.
Children who prefer a familiar crisp snack
Decide whether the child wants an actual rice cake or would also eat a lentil-based cake. The distinction matters when choosing between the higher-protein options.
What should you check?
Start with protein per 100g, then consider the portion going into the lunchbox. Check allergens and school arrangements separately from the nutrition figures.
| Priority | What to check | Your needs |
|---|---|---|
| Protein | Compare protein per 100g before comparing portions. M&S lists 24.8g per 100g for its high-protein rice cakes; Tesco lists 9.3g per 100g for its lightly salted rice cakes. | I want the snack itself to contribute more protein, rather than choosing a plain rice cake on the strength of its name or format. |
| Allergens | Read the current pack’s ingredients, gluten-free statement where relevant, and precautionary allergen wording. Kallo warns that its Protein Packed Lentil Cakes may contain milk, sesame seed and soya. | Before I pack it, I need to know whether this exact product fits the child’s allergen requirements. |
| School rules | Check the school’s allergy policy and any arrangements for the child. Department for Education guidance for England requires schools to publish an allergy safety policy; it does not establish one packed-lunch rule for every UK school. | A product’s label alone cannot tell me whether it fits my child’s school arrangements. |
| Snack format | Check whether the product is a rice cake or a lentil cake, and compare protein for the portion you plan to pack. Tesco lists 0.7g protein per lightly salted rice cake; Kallo lists 0.6g per organic lightly salted rice cake. | If a plain rice cake is the snack my child prefers, I can plan the rest of the lunch without treating that cake as the main protein item. |
Common packed-lunch mistakes
-
Assuming every rice cake is high in protein
Tesco’s Lightly Salted Rice Cakes list 0.7g protein per cake, while Kallo’s Organic Lightly Salted Rice Cakes list 0.6g per cake. A plain cake is a different choice from a specifically formulated high-protein snack.
Compare labels per 100g and for the portion you intend to pack. If you choose plain cakes, consider what other foods are going into the lunch.
-
Treating gluten free as clearance for every allergen
Gluten-free status does not remove separate allergen warnings. Kallo’s Protein Packed Lentil Cakes warn that they may contain milk, sesame seed and soya.
Read the ingredients and precautionary wording on the current pack against the child’s allergen requirements.
-
Assuming every school has the same lunchbox rules
Department for Education allergy guidance applies to England and requires schools to publish an allergy safety policy. It does not tell you what an individual school permits in a packed lunch.
Check the child’s school policy and any individual arrangements before sending a new snack.
-
Planning lunches around stock you have not checked
A snack cannot serve as a regular lunchbox option if it is unavailable when you need it.
Check current stock, delivery options and the product label before adding it to a school-week shop.
Relevant brand options
M&S
Its Barbecue High Protein Rice Cakes are an option when the snack needs to remain a rice cake.
- M&S lists 24.8g protein per 100g and labels this product gluten free.
- Check whether the barbecue flavour suits the child, as well as the current pack label.
Kallo
Kallo offers both Protein Packed Lentil Cakes and plain Organic Lightly Salted Rice Cakes; they answer different lunchbox needs.
- Kallo lists 26.0g protein per 100g for its lentil cakes.
- The lentil cakes are not conventional rice cakes and carry a may-contain warning for milk, sesame seed and soya. Kallo lists 0.6g protein per plain rice cake.
Tesco
Tesco Lightly Salted Rice Cakes are a plain rice-cake option when the lunch includes other foods contributing protein.
- Tesco lists protein both per 100g and per cake, making portion comparisons straightforward.
- At 0.7g protein per cake, this product should not be mistaken for a specifically high-protein snack. Check the current pack for ingredient and allergen information.
Snack a Jacks
Its flavoured multipacks may suit a child who prefers a familiar crisp snack format.
- Individual flavour packs provide the nutrition information needed to assess the chosen snack.
- Check that pack’s protein figure and allergen information rather than assuming the multipack meets a high-protein brief.
Joybuy lentil-cake option
This lentil-cake option is for a packed lunch where a crisp cake is wanted but rice does not need to be the main ingredient.

Kallo Protein Packed Lentil Cakes 100g
These lentil cakes offer a rice-cake-style alternative when rice itself is not essential. Kallo’s own product information lists 26.0g protein per 100g and warns that the cakes may contain milk, sesame seed and soya. Check the current pack’s nutrition and allergen information before packing them.
Questions about rice cakes and packed lunches
Are plain rice cakes a high-protein lunchbox snack?
Do not assume so from the rice-cake format. Tesco lists 0.7g protein per Lightly Salted Rice Cake, and Kallo lists 0.6g per Organic Lightly Salted Rice Cake. Compare the portion you would pack with a specifically formulated option, or consider the other foods in the lunch.
Do rice cakes always contain gluten?
No. M&S labels its Barbecue High Protein Rice Cakes gluten free, and Kallo labels its Organic Lightly Salted Rice Cakes gluten free. Check the exact current pack rather than extending either product’s claim to all rice cakes or to other allergens.
What does a may-contain warning mean for this choice?
The Food Standards Agency explains that precautionary allergen labelling communicates possible unintended allergen presence. Kallo says its Protein Packed Lentil Cakes may contain milk, sesame seed and soya, so check that warning against the child’s allergen requirements rather than relying on a gluten-free claim alone.
Will a school accept a gluten-free rice cake in a packed lunch?
A gluten-free label does not establish what an individual school accepts. Department for Education allergy guidance for England requires schools to publish an allergy safety policy; check the child’s school policy and any individual arrangements before packing the product.
