Choose a rice or lentil cake only after checking the current pack against the allergen you need to avoid; a gluten-free claim does not settle other allergy questions. Kallo lists 26g protein per 100g for its Protein Packed Lentil Cakes, but its shop page warns that they may contain milk, sesame seed and soya. M&S lists 24.8g per 100g for its Barbecue High Protein Rice Cakes, whose recipe includes pea protein and lentil flour; its current pack needs checking too.
Who is this choice for?
Allergy-aware shoppers comparing protein figures
If you want a protein-focused crunchy snack, check its ingredients and precautionary allergen statements before comparing nutrition figures. Suitability depends on the allergen you avoid and the pack you buy.
Gluten-free shoppers with other allergies
Gluten-free does not mean free from every allergen. Kallo labels its Protein Packed Lentil Cakes gluten free, while the Kallo UK Shop says they may contain milk, sesame seed and soya.
Shoppers weighing up plain rice cakes
Compare like-sized portions as well as figures per 100g. Sainsbury's lists 0.6g protein per plain rice cake, while Kallo lists 1.8g per Protein Packed Lentil Cake; neither figure replaces an allergen check.
What should you check first?
Start with the allergens relevant to you, then compare protein figures on the same basis and check the portion you would eat.
| Priority | What to check | Your needs |
| Allergen statements |
Read the current pack's ingredients, allergen information and any 'may contain' warning. Kallo UK Shop lists milk, sesame seed and soya in a precautionary warning for its Protein Packed Lentil Cakes. |
I need to check the particular allergen I avoid before deciding whether this product fits my requirements; a gluten-free label alone cannot answer that question. |
| Protein figures |
Compare protein per 100g, then per cake where stated. Kallo lists 26g per 100g and 1.8g per cake; M&S lists 24.8g per 100g for Barbecue High Protein Rice Cakes. Sainsbury's lists 8.1g per 100g and 0.6g per plain rice cake. |
If I usually eat one or two cakes, the per-cake figure helps me judge the portion as well as the per-100g comparison. I'll use the figures on the pack I buy. |
| Recipe ingredients |
M&S lists wholegrain rice, buckwheat, pea protein and lentil flour in its Barbecue High Protein Rice Cakes. Check the complete pack ingredients against those you need to avoid. |
Pea, lentil or buckwheat ingredients may matter to me independently of a front-of-pack gluten-free claim. |
| Current pack |
Check the pack at each purchase rather than relying on an earlier listing. M&S says ingredients and allergen information for its Barbecue High Protein Rice Cakes may change. |
I want the allergen and nutrition information for the actual pack I'm buying, particularly if its packaging or recipe looks different. |
Common buying mistakes
-
Treating gluten free as an all-allergen claim
Kallo labels its Protein Packed Lentil Cakes gluten free, but Kallo UK Shop also warns that they may contain milk, sesame seed and soya.
Read the current pack for every ingredient and precautionary statement relevant to the allergen you avoid.
-
Comparing protein per 100g alone
Protein per 100g describes the food, not the amount in one cake. Kallo lists 26g per 100g and 1.8g per Protein Packed Lentil Cake.
Check the per-cake or per-serving figure where available and compare the portion you would actually eat.
-
Assuming a plain recipe rules out allergen warnings
Sainsbury's says its plain rice cakes are not suitable for customers with a milk allergy because of manufacturing methods. The Food Standards Agency explains that 'may contain' labelling communicates possible unintended allergen presence.
Check manufacturing and precautionary warnings as well as ingredients intentionally added to the recipe.
-
Using an old product listing as the final check
M&S warns that ingredients and allergen information for its Barbecue High Protein Rice Cakes may change.
Read the physical pack when you buy it, including after a packaging or recipe change.

Questions about protein and allergens
Is a gluten-free lentil cake suitable for every food allergy?
No. Kallo labels its Protein Packed Lentil Cakes gluten free, but Kallo UK Shop says they may contain milk, sesame seed and soya. Check the current pack against the allergen you avoid rather than treating gluten-free status as a broader assurance.
What allergen information should I read on the pack?
Read the full ingredient list, allergen information and any precautionary warning relevant to you. The Food Standards Agency explains that 'may contain' labelling communicates that a regulated allergen could be unintentionally present; it is different from listing an intentionally added ingredient.
How does a plain rice cake compare for protein?
Protein varies by product. Sainsbury's lists 8.1g per 100g and 0.6g per plain rice cake, while Kallo lists 26g per 100g and 1.8g per Protein Packed Lentil Cake. Compare the current packs and the portions you intend to eat.
Can I use a supermarket webpage instead of the packet?
Use the current packet for the final ingredient and allergen check. M&S says information for its Barbecue High Protein Rice Cakes may change, so an online description may not reflect the pack you buy.
