Families comparing protein per portion
If you want the crunchy snack itself to contribute protein, compare both the per-100g figure and the amount in an individual cake. Tesco lists 1.8g protein per Kallo Protein Packed Lentil Cake.
Who is this for?
Shoppers checking school allergens
A gluten-free label does not answer every allergen question. Read the exact pack for ingredients and precautionary warnings, then check the school's allergy arrangements before packing it.
Children who prefer familiar rice cakes
Consider whether a savoury lentil cake or a barbecue-flavoured rice cake will be eaten. A plain rice cake remains an option when its familiar format matters more than its own protein content.
What should you check?
Start with protein per 100g, then compare the portion, flavour and pack information that matter for the lunchbox.
| Priority | What to check | Your needs |
|---|---|---|
| Protein in the portion | Compare protein per 100g on the same basis, then check the per-cake or serving figure. Tesco lists 26g per 100g but 1.8g per cake for Kallo Protein Packed Lentil Cakes; check the particular pack, as product information can differ. | I want to know what the amount packed contributes, not just what the front-of-pack name suggests. |
| Allergens and school rules | Read the current ingredients and allergen statements, including any precautionary warnings. Check the individual school's allergy policy. | A gluten-free label matters to me, but I also need to check other allergens and whether the snack fits school arrangements. |
| Format and flavour | Distinguish rice cakes from lentil or veggie cakes. Compare plain, barbecue and other savoury flavours with what the child will eat. | If plain rice cakes are the only acceptable option, I would not count on a flavoured alternative being eaten. |
| Fat and salt | Read fat and salt per 100g alongside protein. Marks & Spencer lists 16.2g fat and 0.60g salt per 100g for its Barbecue High Protein Rice Cakes; Tesco lists 12g fat and 1.1g salt for Kallo Beetroot Veggie Cakes. | I want to compare the whole nutrition panel rather than decide from the protein figure alone. |
Common buying mistakes
-
Assuming every rice cake is high in protein
Tesco's plain rice cakes list 9.3g protein per 100g and Sainsbury's list 8.1g, compared with 24.8g per 100g for Marks & Spencer's Barbecue High Protein Rice Cakes.
Compare per-100g values, then check the protein in the number of cakes going into the lunchbox.
-
Using gluten-free as the only allergen check
Tesco's listing says Kallo Protein Packed Lentil Cakes may contain sesame and soya. Sainsbury's says Snack a Jacks Chocolate Chip Jumbo Rice Cakes may contain wheat and other cereals containing gluten.
Read the current pack for the exact product and follow the school's allergy arrangements.
-
Choosing from the protein figure alone
Protein-led cakes differ in format, flavour, fat and salt. Marks & Spencer's barbecue rice cakes and Kallo's beetroot veggie cakes have different nutrition panels as well as different ingredients.
Compare the full panel and allergen statement, and consider whether the child will eat the flavour offered.
Relevant brand references
Kallo
Its Protein Packed Lentil Cakes and Beetroot Veggie Cakes offer legume-based alternatives to conventional rice cakes.
- Tesco lists 26g protein per 100g for the Protein Packed Lentil Cakes and 25g per 100g for the Beetroot Veggie Cakes.
- They are not plain rice cakes. Check the exact pack: Tesco lists sesame and soya warnings for the lentil cakes, and milk, soya and sesame warnings for the veggie cakes.
M&S
Its Barbecue High Protein Rice Cakes are an option for shoppers who specifically want a product sold as rice cakes.
- Marks & Spencer lists 24.8g protein per 100g and labels the product gluten free and vegan.
- The barbecue flavour may not suit a child who prefers plain cakes; the panel lists 16.2g fat and 0.60g salt per 100g.
Snack a Jacks
Its Chocolate Chip Jumbo Rice Cakes provide a flavoured rice-cake reference rather than a protein-led comparison product.
- Sainsbury's lists 6.1g protein and 9.9g fibre per 100g for this product.
- Its allergen statement says it may contain wheat, mustard and other cereals containing gluten.
Tesco
Its Lightly Salted Rice Cakes provide a plain-cake comparison with the Kallo lentil cakes listed by the retailer.
- Tesco lists brown rice and sea salt as the ingredients of its Lightly Salted Rice Cakes.
- The plain cakes list 9.3g protein per 100g, compared with 26g per 100g on Tesco's Kallo Protein Packed Lentil Cakes listing.
Sainsbury's
Its own-brand rice cakes provide another plain-cake reference for the lunchbox decision.
- Sainsbury's lists its 135g Rice Cakes as gluten free and prepared to a vegan recipe.
- They list 8.1g protein per 100g and 0.6g per cake; check the portion rather than treating a plain cake as a protein-led snack.

Kallo Protein Packed Lentil Cakes 100g
A savoury lentil-cake alternative for a child willing to try a different format from plain rice cakes. Check this pack's protein per 100g and its milk, sesame and soya declarations before packing it: product information for this Joybuy SKU differs from Tesco's Kallo listing.
Frequently asked questions
Are ordinary rice cakes high in protein?
The plain products in this comparison contain less protein per 100g than the protein-led cakes: Tesco lists 9.3g for its Lightly Salted Rice Cakes and Sainsbury's lists 8.1g for its own rice cakes. Marks & Spencer lists 24.8g per 100g for its Barbecue High Protein Rice Cakes; check per-cake figures as well when planning a portion.
Does gluten-free mean a cake is clear of other allergens?
No. Tesco lists precautionary sesame and soya warnings for Kallo Protein Packed Lentil Cakes, despite their gluten-free label, and milk, soya and sesame warnings for Kallo Beetroot Veggie Cakes. Read the current physical pack for the exact product before putting it in a school lunch.
What should I check with the school about food allergies?
Check the individual school's published allergy safety policy and any packed-lunch arrangements that apply to your child. Department for Education guidance for England says schools must publish a policy setting out how they reduce contact with pupils' known allergens.
What if a child will only eat plain rice cakes?
A plain rice cake can remain the familiar choice, but do not count it as equivalent in protein to the protein-led products compared here. If protein from the lunch is a priority, consider the other foods being packed as well as the cake's per-portion figure.
