Shoppers comparing fat content
If fat per 100g is your main criterion, the published figures for the plain M&S and Kallo products give you a more useful comparison than calories per cake alone.
Who these choices suit
People looking for a plain topping base
A lightly salted rice cake leaves the choice of topping to you. Compare the exact product label if ingredients or allergens affect your choice.
Shoppers wanting a portioned savoury snack
A flavoured single-serve pack may be more convenient to carry than a pack of plain cakes. Compare fat per 100g separately from calories per pack.
What to check before choosing
Start with fat per 100g for a like-for-like nutrition comparison, then consider flavour, pack format and whether the exact item can be added to your delivery order.
| Priority | What to check | Your needs |
|---|---|---|
| Fat content | Compare fat per 100g on the exact listings. Ocado lists M&S Lightly Salted at 2.5g and Snack a Jacks Salt & Vinegar at 9.9g; Tesco Groceries lists Kallo Lightly Salted at 2.8g. | I want to compare products on the same basis, rather than choosing by calories per cake or pack. |
| Label wording | Read the per-100g nutrition panel alongside any low-fat or reduced-fat wording. Check what product a reduction claim is being compared with. | If lower fat is my priority, I do not want to treat different label claims as interchangeable. |
| Pack and delivery | Check the serving and pack size, then confirm the exact item in your basket for your postcode and delivery slot. Tesco Groceries marked its own-label Lightly Salted Rice Cakes out of stock on the cited listing. | For toppings, I would choose a plain pack; for a snack to carry, a portioned flavoured pack may suit me better. |
| Ingredients and allergens | Read the current ingredient list and allergen information for the exact variant, particularly when choosing between plain and flavoured products. | Dietary or allergen requirements mean I need to check the product label, not rely on its flavour or a shopping filter. |
Common buying mistakes
-
Using calories per pack as a fat comparison
Ocado lists a 23g Snack a Jacks Salt & Vinegar pack at 97 kcal, but also lists 9.9g fat per 100g. The two figures answer different questions.
Use fat per 100g to compare products, then check calories per serving if the portion size matters to you.
-
Reading “reduced fat” as “low fat”
The phrases do not describe the same comparison: a reduction needs a reference product, while the fat figure on the nutrition panel describes the product itself.
Check the per-100g figure and read what any reduction wording compares the product with.
-
Assuming a search result means an item can be delivered
A listing may not be available for the order you are placing. Tesco Groceries marked its own-label Lightly Salted Rice Cakes out of stock on the cited product page.
Confirm the item in your basket after selecting a delivery slot, and review any suggested substitution before checkout.
-
Skipping the allergen panel on a plain rice cake
A simple flavour or short ingredient list does not replace the allergen information for the exact product.
Read the current retailer panel or pack label if an ingredient or precautionary allergen statement affects your choice.
Brand and product-line references
These figures describe the specific products named, not every rice cake made by each brand.
Kallo
Tesco Groceries lists Kallo Lightly Salted Wholegrain Low Fat Rice Cakes as a plain, lightly salted option.
- The cited Tesco listing gives 2.8g fat per 100g and labels this product low fat.
- Check the current allergen panel and availability for the exact listing you intend to order.
M&S
M&S Lightly Salted Rice Cakes are a plain option listed through Ocado.
- Ocado lists 2.5g fat per 100g for this product.
- Check delivery eligibility and the current listing before placing an order.
Tesco
Tesco Lightly Salted Rice Cakes offer an own-label rice-and-salt option.
- Tesco Groceries lists rice and salt as the ingredients and 3.1g fat per 100g.
- The cited product listing marked this item out of stock; check its status for your order.
Snack a Jacks
The Salt & Vinegar rice-cake pack is a flavoured, portioned alternative to the plain products above.
- Ocado lists 97 kcal per 23g pack.
- The same listing gives 9.9g fat per 100g, so the per-pack calorie figure should not stand in for a fat comparison.

Questions about choosing rice cakes
Are “reduced fat” and “low fat” the same thing?
No. A lower-fat comparison needs a product to compare against; a low-fat label is a different claim. Check the exact product’s fat per 100g and what any reduction wording compares it with.
Which of the plain rice cakes compared here lists the least fat per 100g?
Ocado lists M&S Lightly Salted Rice Cakes at 2.5g fat per 100g. Tesco Groceries lists Kallo Lightly Salted at 2.8g and Tesco Lightly Salted at 3.1g per 100g. Those figures compare the named products, not every rice cake available for delivery.
Does a pack under 100 kcal necessarily contain little fat?
No. Ocado lists the Snack a Jacks Salt & Vinegar 23g pack at 97 kcal per pack and 9.9g fat per 100g. Use the per-100g figure for a fat comparison and the per-pack figure to assess the serving.
What should I check before adding rice cakes to a delivery order?
Check the exact product’s current nutrition and allergen label, then confirm that it remains in your basket for your selected postcode and delivery slot. Review any substitution rather than assuming it has the same ingredients or nutrition figures.
Do plain or vegan-labelled rice cakes still need an allergen check?
Yes. A plain flavour or vegan description does not replace the allergen information for the exact product. Read the current pack or retailer panel if an ingredient or precautionary statement affects your choice.
