Walkers Cheese & Onion contains 516 kcal, 30g of fat (2.4g saturated), 60g of carbohydrate (1.2g sugar), 4g of fibre, 6.8g of protein and 1.72g of salt per 100g.
Walkers Cheese & Onion uses dried cheese and onion powder in its flavouring blend, triggering a milk allergen declaration despite the low actual dairy content. At 1.72g of salt per 100g, a grab bag (45g) delivers 0.77g of salt, 13% of the adult daily limit.
A standard bag (25g) and a sharing bag (150g) contain very different amounts. A standard bag delivers 129 kcal and 0.43g of salt. A sharing bag delivers 774 kcal and 2.58g of salt, 43% of the adult daily limit, from a single product.
This matters because crisps are one of the easiest snacks to eat passively. Opening a sharing bag while watching television, or finishing a grab bag that was opened for a small snack, is common. The table above shows the nutritional impact at each pack size so the difference is visible before reaching into the bag.

Salt
Walkers Cheese & Onion contains 1.72g of salt per 100g. A standard bag (25g) delivers 0.43g of salt, 7% of the adult daily limit of 6g and 14% of the limit for a child aged 4 to 6 (3g). A sharing bag (150g) delivers 2.58g of salt, 43% of the adult daily limit.

The saturated fat content of 2.4g per 100g is relatively low for this type of snack. Most crisps fried in sunflower oil contain 2 to 3.5g of saturated fat per 100g.
Sugar
Walkers Cheese & Onion contains 1.2g of sugar per 100g. For most savoury snacks, sugar is a minor component of the seasoning blend rather than a primary ingredient. A standard bag (25g) contains 0.3g of sugar, a negligible contribution to the daily free sugar limit of 30g for adults.
Fibre and protein
Walkers Cheese & Onion contains 4g of fibre and 6.8g of protein per 100g. A standard bag (25g) provides 1g of fibre (3% of the adult daily target of 30g) and 1.7g of protein.
Ultra-processed food: what is really in it
Walkers Cheese & Onion is made from one main component: potato crisps.
Reading the ingredient list closely, it contains flavourings and colourings. Flavourings create or enhance the taste of the product, often replacing or supplementing natural flavour sources to deliver a consistent result across batches. Colourings standardise the appearance of the seasoning across batches, since natural ingredients vary in colour.
A home-made equivalent, prepared in one kitchen from whole ingredients, would use a handful of recognisable components with no additives. These processing aids are used because the brief contact time during industrial frying or baking is insufficient to develop the complex, stable flavours the seasoning provides at scale.
Looking at the ingredient list tells a different story from just the headline numbers. The additives and processing aids give this product its consistent flavour at industrial scale.
Processing (NOVA classification)
Walkers Cheese & Onion falls into NOVA group 4, ultra-processed food. The NOVA classification system groups foods by the extent and purpose of the processing involved. Group 4 covers products formulated from substances derived from foods plus additives, with little or no whole food recognisable in the final product. In this item that includes flavourings and colourings. This classification applies to almost all commercially produced flavoured crisps and snacks, regardless of whether they are marketed as baked, hand-cooked, natural or healthier.
