Protein-focused desk snackers
If a cake-style snack is part of your morning break, check protein per cake as well as per 100g. Kallo lists 1.8g per lentil cake, while Sainsbury's lists 0.7g per lightly salted wholegrain rice cake.
Who are these snacks for?
Vegan or gluten-free snack shoppers
Product-specific dietary wording matters, but it does not replace the allergen statement. Kallo says its Protein Packed Lentil Cakes may contain sesame and soya; Sainsbury's warns that its wholegrain rice cakes are unsuitable for customers with a milk allergy despite being prepared to a vegan recipe.
Shoppers who prefer a topping
A lightly salted wholegrain rice cake can serve as a base for a topping instead of being the protein-focused part of the snack. Check the topping's ingredients and the amounts you plan to use when comparing the finished snack.
What should you compare?
Start with protein in the portion you would eat, then compare the rest of the label and decide whether you want a rice cake, a lentil cake or a base for a topping.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per portion | Compare protein per 100g on the same basis, then check per cake or serving. Kallo lists 1.8g per lentil cake; Sainsbury's lists 0.7g per wholegrain rice cake. | I want to know what the cakes I actually eat contribute, rather than choosing by a per-100g figure alone. |
| Rest of the nutrition label | Read fat and energy alongside protein on the current packs. Marks & Spencer lists 16.2g fat and 451kcal per 100g for its Barbecue High Protein Rice Cakes; Kallo's published information lists 1.9g fat per 100g for its lentil cakes. | A higher-protein cake appeals to me, but I also want to compare its full nutrition label. Figures for the Kallo product differ between listings, so the current pack is particularly important. |
| Format and flavour | Check whether the product is made as a rice cake or a lentil-based cake, and whether its flavour suits your break. M&S describes a barbecue rice cake; Kallo's option is a lentil cake. | I would rather choose a format and flavour I want to eat than treat the two products as interchangeable. |
| Ingredients and allergens | Read the current ingredients and precautionary allergen statement. Kallo says its lentil cakes may contain sesame and soya; Sainsbury's gives a milk-allergy warning for its wholegrain rice cakes. | Vegan or gluten-free wording matters to me, but I still need to check the warnings for the particular pack. |
What is easy to overlook?

Assuming every rice cake is protein-focused
Sainsbury's lists 0.7g protein per lightly salted wholegrain rice cake, compared with Kallo's published 1.8g per lentil cake. The category name alone does not tell you what one cake provides.
Compare both per-100g and per-cake figures before choosing your portion.
-
Comparing protein but not the rest of the label
High-protein products can have different nutrition profiles: Marks & Spencer lists 16.2g fat per 100g for its barbecue rice cakes, while Kallo's published lentil-cake information lists 1.9g per 100g.
Check protein, fat and energy on the current packs using the same measurement basis.
-
Taking vegan wording as complete allergen information
Kallo says its Protein Packed Lentil Cakes may contain sesame and soya. Sainsbury's says its wholegrain rice cakes are prepared to a vegan recipe but are unsuitable for customers with a milk allergy because of manufacturing methods.
Read the ingredients and allergen statement on the pack you buy, rather than relying on the product category or dietary description alone.

Choosing a flavoured cake for its protein without checking
Sainsbury's lists 0.9g protein per 15g serving of Snack a Jacks Jumbo Chocolate Chip Rice Cakes. A flavour-led choice need not serve the same purpose as a protein-focused one.
Check the serving-size and protein figures for the specific flavour you intend to buy.

Kallo Protein Packed Lentil Cakes 100g

Frequently asked questions
What does “high protein” mean on a UK food label?
Under the high-protein claim rule published on legislation.gov.uk, at least 20% of a food's energy value must come from protein. The claim does not tell you how many grams are in one cake, so check the portion figure too.
Is an ordinary rice cake a protein-focused morning snack?
Check the particular product and portion rather than assuming it is: Sainsbury's lists 0.7g protein per Lightly Salted Wholegrain Rice Cake, while Kallo's published information lists 1.8g per Protein Packed Lentil Cake. A plain rice cake may instead suit you as a base for a topping.
How do the named high-protein options compare on fat?
Kallo's published information lists 1.9g fat per 100g for its Protein Packed Lentil Cakes, while Marks & Spencer lists 16.2g per 100g for its Barbecue High Protein Rice Cakes. Check the current packs before relying on that comparison, particularly because published figures for the Kallo product differ between listings.
Does vegan or gluten-free wording cover every allergen concern?
No. Kallo says its Protein Packed Lentil Cakes may contain sesame and soya, and Sainsbury's says its wholegrain rice cakes are unsuitable for customers with a milk allergy despite being prepared to a vegan recipe. Read the current pack's ingredients and allergen statement for the product you choose.
