For a straightforward pre-workout snack when you need to avoid gluten, start with a plain rice cake carrying an explicit gluten-free claim, then check the current pack for any other allergens you avoid. Compare carbohydrate on a per-cake basis to decide how much the snack contributes; flavoured or high-protein cakes can have a different nutritional profile, and a gluten-free claim does not rule out milk, soya or sesame warnings.
If a rice cake is for a snack before exercise and you need to avoid gluten, look for an explicit gluten-free claim rather than relying on rice in the product name. Coeliac UK explains that foods labelled gluten free must contain no more than 20 parts per million of gluten.
A gluten-free claim does not answer questions about milk, soya or sesame. The product information from ASDA Groceries, Tesco Groceries and Sainsbury’s shows different precautionary warnings across their rice cakes, so check the particular pack against the allergens you avoid.
Flavour and protein content can change the nutrition comparison. For example, Marks & Spencer lists different amounts of carbohydrate, fat and protein per 100 g for its Lightly Salted and Barbecue High Protein rice cakes. Compare like-for-like label values and consider the portion you intend to eat before training.
Start with the gluten-free claim and any other allergen requirements, then compare the nutrition panel using the same serving basis.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten-free claim | Look for an explicit claim on the current pack. Coeliac UK says the UK gluten-free label applies to food containing no more than 20 ppm gluten; rice as an ingredient is not itself a label claim. | I need to avoid gluten, so I want the particular rice cakes I buy to carry that claim. |
| Other allergens | Read the ingredients and precautionary statements for each allergen you avoid. ASDA Groceries lists a soya may-contain warning for its Free From Slightly Salted cakes; Tesco Groceries lists sesame, soya and milk warnings for its Free From Wholegrain cakes. | Gluten is not my only concern. I need to check whether this product also has a warning relevant to my allergy. |
| Snack portion | Compare carbohydrate per cake where stated, and use the same per-cake or per-100-g basis for fat and other nutrients. ASDA Groceries lists 6.2 g carbohydrate per Free From Slightly Salted cake; its serving may differ from another product’s. | Before training, I want to know what my planned number of cakes contributes, rather than judging the snack by words such as “light”. |
| Plain or flavoured | Check the nutrition panel rather than treating the versions as interchangeable. Marks & Spencer lists 2.5 g fat and 0.33 g salt per 100 g for Lightly Salted, against 16.2 g fat and 0.60 g salt per 100 g for Barbecue High Protein. | I might prefer a savoury or flavoured cake, but I want to compare its actual portion with the plain option I would otherwise eat. |
| Current packaging | Check the physical pack at purchase and before eating. Leeds Teaching Hospitals NHS Trust advises checking each time because recipes can change. | Even if I buy the same rice cakes regularly, I need the ingredient and allergy information for the pack in hand. |
The claim concerns gluten. The reviewed gluten-free cakes include separate may-contain warnings for soya, milk or sesame, depending on the product.
Identify each allergen you need to avoid, then read both the ingredient list and precautionary statements on the current pack.
Sainsbury’s says its reviewed plain and lightly salted rice cakes are prepared to a vegan recipe but are not suitable for customers with a milk allergy because of manufacturing methods.
For a milk allergy, follow the product’s allergy advice rather than treating vegan suitability as an equivalent claim.
Marks & Spencer lists substantially different fat and salt values per 100 g for its Lightly Salted and Barbecue High Protein cakes. A per-cake figure and a per-100-g figure cannot be compared as though they were the same portion.
Put the nutrition values on the same basis and consider how many cakes you plan to eat before training.
Ingredients and allergy information can change even when you recognise the product.
Leeds Teaching Hospitals NHS Trust advises checking the label at purchase and again before use, particularly when an allergy is involved.
These examples show why the label on a particular product matters more than the brand name alone; they do not establish that every product from a brand has the same ingredients or warnings.
Its Slightly Salted Rice Cakes are a plain, explicitly gluten-free example.
The reviewed Organic Lightly Salted Wholegrain Rice Cakes provide a labelled gluten-free option.
The reviewed Free From Wholegrain and standard Lightly Salted cakes have different label information.
The reviewed plain and lightly salted 135 g rice cakes both carry a gluten-free claim.
The reviewed Lightly Salted and Barbecue High Protein cakes illustrate two different nutritional profiles within a gluten-free range.
A flavoured rice-cake range to assess product by product when shopping for a free-from snack.
These Kallo options include a lightly salted cake for the plain-snack route and an apple-and-cinnamon cake if you prefer a flavoured snack. Check the current pack against your own gluten and other allergen requirements before choosing either.

A lightly salted option to consider when you want a plain rice cake before training. ASDA Groceries lists the reviewed Kallo Organic Lightly Salted Wholegrain 130 g cakes as gluten free, with 5.6 g carbohydrate per cake, and warns that they may contain milk, sesame and soya. Check the pack of the product you receive for its current claims and warnings.

An apple-and-cinnamon alternative if flavour matters to your pre-workout snack choice. If you need gluten-free food, confirm an explicit claim on the current pack; also read its allergen statements and compare its nutrition panel with any plain cakes you are considering.
No. Coeliac UK explains that a UK gluten-free label applies to food containing no more than 20 ppm gluten; it does not rule out warnings for other allergens. For example, ASDA Groceries lists a soya may-contain warning for its Free From Slightly Salted cakes, while Tesco Groceries lists sesame, soya and milk warnings for its Free From Wholegrain cakes.
Yes. Sainsbury’s says its reviewed plain and lightly salted cakes are prepared to a vegan recipe but are not suitable for customers with a milk allergy because of manufacturing methods. Read the allergy advice on the specific pack.
Check carbohydrate per cake where the label provides it, then consider the number of cakes and any other food in your planned snack. UK Sports Institute guidance notes that carbohydrate needs rise with exercise intensity and duration, so a single cake should not be treated as a complete fuelling plan for every session.
Not on nutrition values alone. Marks & Spencer lists 24.8 g protein and 16.2 g fat per 100 g for Barbecue High Protein, compared with 9.6 g protein and 2.5 g fat per 100 g for Lightly Salted. Compare the portion you would eat and check its ingredients and allergen advice.
Yes, particularly if you manage an allergy. Leeds Teaching Hospitals NHS Trust advises checking at purchase and before eating because manufacturers can change recipes.
