For a protein-focused night-shift snack, compare lentil or veggie cakes rather than assuming plain rice cakes supply much protein. Sainsbury's lists 26g protein per 100g for Kallo Protein Lentil Cakes and 25g per 100g for Kallo Beetroot & Balsamic Veggie Cakes, against 8.1g per 100g for its plain rice cakes. Plain rice cakes can still serve as a topping base; compare protein per cake as well as per 100g, and check the current pack for allergens.
Who these snacks suit
Workers packing a protein-focused break snack
Cake-style snacks are easy to portion for a shift, but protein per cake matters when choosing what to pack. Barking, Havering and Redbridge University Hospitals NHS Trust advises considering smaller snacks or a light meal during night breaks rather than one large meal.
Shoppers checking vegan, gluten-free or allergen information
A dietary description is only a starting point. Tesco lists sesame and soya precautionary information for Kallo Protein Lentil Cakes, while Sainsbury's says its plain rice cakes are not suitable for customers with a milk allergy because of manufacturing methods.
People using plain rice cakes as a topping base
Plain cakes offer a way to carry a topping, but the cake itself contributes little protein per piece: Sainsbury's lists 0.6g protein per plain rice cake.
What to compare before buying
Start with protein per cake for the break you are planning, then compare products per 100g and check the exact pack's ingredients and allergen statement.

What to check |
Your needs |
| Protein |
Compare protein per 100g and per cake; cake sizes differ. Sainsbury's lists 26g per 100g and 1.8g per Kallo lentil cake, 25g per 100g and 2.4g per Kallo veggie cake, and 8.1g per 100g and 0.6g per plain rice cake. |
I want the cake itself to contribute protein, rather than relying on a topping to provide it. |
| Break portion |
Check the number of cakes you plan to pack and the nutrition per cake. Decide whether they are a small snack or one part of a light meal. |
For a short night break, I would rather pack a portion that fits the rest of my food than treat one cake as a meal. Barking, Havering and Redbridge University Hospitals NHS Trust suggests smaller snacks or a light meal instead of one large meal at night. |
| Allergens |
Read the current ingredients and precautionary statements for the exact variant. Tesco lists possible sesame and soya presence for Kallo Protein Lentil Cakes; Sainsbury's warns that its plain rice cakes are unsuitable for customers with a milk allergy. |
If I need to avoid an ingredient, I need the pack's allergen information—not just a vegan or gluten-free description. |
| Salt and flavour |
Compare salt per 100g and per cake when switching to a flavoured product. Sainsbury's lists 1.1g salt per 100g for Kallo Beetroot & Balsamic Veggie Cakes. |
I may prefer a savoury cake, but I still want to check its salt figure alongside the protein figure. |
Common buying mistakes
-
Assuming every rice cake is protein-rich
Protein per 100g can obscure how little an individual cake supplies. Sainsbury's lists 0.6g protein per plain rice cake.
If protein is the reason for buying, compare both the per-cake and per-100g figures with the portion you intend to eat.
-
Counting one cake as a complete break meal
Sainsbury's lists 1.8g protein per Kallo lentil cake and 2.4g per Kallo veggie cake. One piece and a light meal are different amounts of food.
Plan the rest of your break food separately. Barking, Havering and Redbridge University Hospitals NHS Trust suggests smaller snacks or a light meal during night breaks rather than one large meal.
-
Assuming similar-looking cakes have the same ingredients
A plain rice cake and a flavoured veggie cake need separate label checks. Sainsbury's lists 1.1g salt per 100g for Kallo Beetroot & Balsamic Veggie Cakes and a milk-allergy warning for its own plain rice cakes.
Read the salt line, ingredients and allergen statement for the particular flavour and pack you are buying.
-
Relying on a vegan description when allergen details conflict
The Joybuy information for Kallo Protein Packed Lentil Cakes describes the product as vegan but also lists MILK among its allergens. Those statements cannot establish suitability for someone avoiding milk.
Do not rely on the vegan description for that purpose; check the physical pack and seek clarification from the manufacturer before choosing it.
Brands and retailer labels to compare
Kallo
Kallo has conventional rice cakes as well as lentil and veggie cakes, so the product type matters as much as the brand name.
- Sainsbury's lists 26g protein per 100g for Kallo Protein Lentil Cakes and 25g per 100g for Kallo Beetroot & Balsamic Veggie Cakes.
- Kallo lists 8.5g per 100g and 0.6g per cake for its Organic Lightly Salted Rice Cakes. Do not transfer figures from one Kallo cake to another.
Sainsbury's
Its own-label plain rice cakes are a topping base rather than a protein-led cake option.
- Sainsbury's lists 8.1g protein per 100g and 0.6g per plain rice cake.
- Although prepared to a vegan recipe, the product is labelled unsuitable for customers with a milk allergy because of manufacturing methods.
Tesco
Tesco's listing provides per-100g and per-cake figures for Kallo Protein Lentil Cakes.
- The listing gives 26g protein per 100g and 1.8g per lentil cake.
- It also says the product may contain sesame and soya; check the pack if either matters to you.
Snack a Jacks
Its Sour Cream & Chive Jumbo Rice Cakes offer a flavoured rice-cake option, not the same protein figures as the lentil cakes above.
- Tesco lists 8.6g protein per 100g and 0.8g per serving for this product.
- The listing says it contains milk and may contain wheat, soya, mustard and other cereals containing gluten.
Joybuy lentil cake option
This lentil cake pack is an option to consider if you want a cake-style snack for a night shift. Check its own pack rather than applying nutrition figures from another retailer's listing to it.

Kallo Protein Packed Lentil Cakes 100g
These lentil cakes can be portioned for a shift break. Check the physical pack's protein figures before choosing a portion: listings for this named product differ. The Joybuy product information also describes it as vegan while listing MILK, SESAME SEED and SOYA as allergens; do not rely on that vegan description if milk avoidance matters.

Questions about night-shift snacks
Are plain rice cakes a protein-focused snack?
Not on their own if you are choosing the cake for its protein. Sainsbury's lists 8.1g protein per 100g and 0.6g per plain rice cake; Kallo lists 8.5g per 100g and 0.6g per cake for its Organic Lightly Salted Rice Cakes. Compare any topping separately.
Do lentil or veggie cakes provide more protein?
The particular Kallo products listed by Sainsbury's do on a per-100g basis: Protein Lentil Cakes list 26g and Beetroot & Balsamic Veggie Cakes list 25g, compared with 8.1g for Sainsbury's plain rice cakes. Their per-cake figures differ too—1.8g for a lentil cake and 2.4g for a veggie cake—so check both measures when planning a portion.
How can rice cakes fit into a night-shift break?
Plain rice cakes can be a topping base, while a lentil or veggie cake may contribute more protein as part of the food you pack. Barking, Havering and Redbridge University Hospitals NHS Trust suggests smaller snacks or a light meal during night breaks rather than one large meal; choose a portion that fits the rest of your break food.
Does a vegan or gluten-free description settle allergen suitability?
No. Tesco says Kallo Protein Lentil Cakes may contain sesame and soya, and Sainsbury's says its plain rice cakes are unsuitable for customers with a milk allergy despite being prepared to a vegan recipe. Check the exact physical pack, particularly where a product description and allergen list conflict.
