What to check before choosing
Start with the protein figure for the amount you expect to eat, then check whether the format, storage instructions and allergen information work at your desk.

What to check |
Your needs |
| Protein per portion |
Compare protein per 100g on the current packs, then check the figure per cake or serving. Tesco lists 0.7g per plain rice cake; Tesco’s Kallo listing gives 1.8g per lentil cake. |
I want the cakes I actually eat at work to contribute protein, not just carry a promising name. |
| Cake format |
Read the ingredients: Kallo’s cakes are lentil-based, while M&S Barbecue High Protein Rice Cakes include wholegrain rice, buckwheat, pea protein and lentil flour. A plain rice cake can instead serve as a base for another food. |
If I specifically want rice cakes, I’ll look at the M&S format. If a lentil cake suits me, I can compare Kallo’s portion information too. |
| Desk storage |
Check whether the exact product is ready to eat and how it must be stored. Tesco’s Kallo listing says to keep it in a cool, dry place, then airtight after opening and use it within 14 days. |
A pack kept in an office cupboard needs storage instructions I can follow after opening. |
| Allergens |
Check the current pack’s ingredients and precautionary statements. Kallo labels its lentil cakes gluten-free but warns of possible sesame and soya; Kallo also flags possible milk cross-contact. |
Even if I need a gluten-free snack, I still have to check any other allergens that matter to me. |
Relevant brand examples
These examples show how a lentil cake, a rice cake with added plant ingredients and a plain rice cake differ; the details apply to the named products, not every item from each brand.
Kallo
Kallo Protein Packed Lentil Cakes are a lentil-based alternative for shoppers willing to move beyond a conventional rice cake.
- Kallo lists 26.0g protein per 100g and labels this product vegan, vegetarian and gluten-free.
- The cakes are primarily lentil-based rather than rice-based. Check the current pack for sesame, soya and milk cross-contact warnings.
M&S
M&S Barbecue High Protein Rice Cakes retain a rice-cake format while including pea protein and lentil flour.
- M&S lists 24.8g protein per 100g and labels the product vegan, vegetarian and gluten-free.
- The barbecue flavour and full nutrition panel matter when deciding whether this particular snack suits your intended portion.
Tesco
Tesco Lightly Salted Rice Cakes offer a plain rice-cake reference point for comparison with protein-led products.
- Tesco lists 27kcal and 0.7g protein per cake, making the per-cake figures straightforward to compare with your intended portion.
- At 9.3g protein per 100g, this named plain product is not equivalent to the protein-led Kallo or M&S examples on protein concentration.

Frequently asked questions
What does “high protein” mean on a food label?
For a high-protein nutrition claim, the legislation cited by the UK Department of Health and Social Care requires at least 20% of the food’s energy value to come from protein. The department’s nutrition-claims guidance addresses the rules in Great Britain; check the actual product claim and nutrition panel rather than assuming “rice-based” means high protein.
Are plain lightly salted rice cakes high in protein?
Do not assume they are. Tesco lists 0.7g protein per cake and 9.3g per 100g for its Lightly Salted Rice Cakes, while its Kallo Protein Packed Lentil Cakes listing gives 1.8g per cake and 26.0g per 100g. Plain cakes can serve as a crunchy base if you plan to add another protein-containing food.
What if I want a rice cake rather than a lentil cake?
M&S Barbecue High Protein Rice Cakes contain wholegrain rice alongside buckwheat, pea protein and lentil flour, and M&S lists 24.8g protein per 100g. Kallo Protein Packed Lentil Cakes are primarily lentil-based, so check the ingredients as well as the protein figure when choosing between these formats.
Does gluten-free mean a cake is suitable for other allergies?
No. A gluten-free label does not answer questions about other allergens. Kallo’s lentil cakes are labelled gluten-free, but the Tesco listing warns of possible sesame and soya, and Kallo also flags possible milk cross-contact. Read the current pack’s statements for the allergens you need to avoid.
How should I keep an opened pack at the office?
For Kallo Protein Packed Lentil Cakes, Tesco’s product instructions say to store the pack in a cool, dry place, keep it airtight after opening and consume it within 14 days. Follow the instructions on the exact pack you buy.
