For a general low-fat choice, check total fat per 100g before calories per pack: NHS food-label guidance sets the low-fat benchmark at 3g or less per 100g. Tesco lists Snack A Jacks Sour Cream & Chive Jumbo Rice Cakes at that benchmark, with 37 kcal per cake; a small pack of another snack can have fewer than 100 kcal without being low fat per 100g.
Start with total fat per 100g, then check the calories and fat in the amount you plan to eat. The NHS low-fat benchmark is 3g of fat or less per 100g; a small serving alone does not establish that a product meets it.
Check whether the calorie figure refers to one cake, an inner bag or the whole pack. Tesco lists 37 kcal per Snack A Jacks Sour Cream & Chive Jumbo Rice Cake and 80 kcal per 19g Snack A Jacks Salt & Vinegar bag, but the products have different fat values per 100g.
Read the ingredients and allergen information on the pack you receive. If a clinician has prescribed a specific fat limit, follow that individual advice rather than assuming a general low-fat label answers the question; Oxford University Hospitals distinguishes its minimal-fat diet guidance from general food-label guidance.
If low fat is the requirement, compare fat per 100g first. Then use the serving information and other label details to decide whether the portion suits you.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Read total fat per 100g, not just fat per pack. NHS guidance uses 3g or less per 100g as its low-fat benchmark. | I want a snack that meets the low-fat benchmark, rather than one that simply comes in a small packet. |
| Serving size | Find the serving weight, calories per serving and number of servings in the pack. Multiply the stated serving values if you plan to eat more than one. | A single cake or inner bag makes the amount easier for me to plan; with a sharing pack, I need to decide how many servings I will have. |
| Salt | Compare salt per 100g on the same basis across products, then check the amount in your planned serving. | If salt matters to my choice, I want to account for the portion I will actually eat, not just the figure on the front of the pack. |
| Allergens | Read the current ingredients and highlighted allergens, including any precautionary statements relevant to you. Check again if the flavour or pack size changes. | I need the particular product and flavour to fit my allergy requirements; a familiar brand name is not enough to establish that. |
Walkers lists Quavers Cheese at 86 kcal per 16g pack but 30.8g fat per 100g. Tesco lists Monster Munch Pickled Onion at 98 kcal per 20g pack and 25.0g fat per 100g. Neither meets the NHS low-fat benchmark.
Use fat per 100g to assess the low-fat requirement; use calories per pack to plan the portion.
Baking does not establish the finished snack’s fat content. Tesco describes its Onion Rings as a baked maize and durum-wheat snack and lists 24.8g fat per 100g.
Compare the total-fat line on the nutrition panel instead of relying on the cooking description.
Calories and fat stated for one cake apply to that cake, not to several eaten together. This matters when choosing from a larger pack of Snack A Jacks Jumbo Rice Cakes.
Check the stated serving size and decide how many cakes you intend to eat.
Seasonings and precautionary allergen statements vary between products and flavours. A flavour name cannot tell you whether the pack meets your allergy requirements.
Read the ingredients and allergen statement on the current pack before eating it.
Rice-and-maize cakes offer a different format from conventional maize puffs, but flavours differ in fat content.
The checked Quavers, Monster Munch and Wotsits products provide familiar flavoured snack options in stated portions, rather than a low-fat route.
Tesco’s own-brand maize snacks provide another labelled product to compare when checking fat and ingredients.
These are rice-cake options, including a sweet caramel variant, rather than a selection of conventional savoury maize puffs. Check each current nutrition panel against your fat and portion requirements.

No. The calorie figure usually applies to a serving or pack, while NHS guidance uses 3g fat or less per 100g as its low-fat benchmark. Walkers lists Quavers Cheese at 86 kcal per 16g pack but 30.8g fat per 100g; Tesco lists Monster Munch Pickled Onion at 98 kcal per 20g pack but 25.0g fat per 100g.
No. Baking describes how a snack is made, not its total fat content. Tesco describes its Onion Rings as baked and lists 24.8g fat per 100g, so check the nutrition panel rather than the cooking description.
Tesco lists Snack A Jacks Sour Cream & Chive Jumbo Rice Cakes at 3.0g fat per 100g, exactly matching the NHS low-fat benchmark. This is a rice-and-maize cake rather than a conventional maize puff; Tesco lists 37 kcal and 0.3g fat per 9.7g cake.
Check the ingredients, highlighted allergens and any relevant precautionary statements on the pack you receive, even if you have bought the product before. GOV.UK guidance explains that required allergens must be emphasised in the ingredients list of relevant pre-packed foods.
Not necessarily. Oxford University Hospitals’ minimal-fat diet guidance is aimed at people given a specific limit by a healthcare professional. If you have been prescribed a fat limit, use your clinical team’s individual instructions when assessing a snack, including the amount you intend to eat.
