Salt highlighted in amber above 38% of adult daily limit (2.3g), red above 75% (4.5g). All figures calculated from per-100g nutrition.
Seabrook Crinkle Cut Cheese & Onion contains 540 kcal, 34g of fat (3.2g saturated), 56g of carbohydrate (1.6g sugar), 3.2g of fibre, 6g of protein and 1.8g of salt per 100g.
Seabrook Cheese & Onion is a rich, savoury staple. The crinkle-cut format increases surface area per crisp, holding more seasoning per gram. At 540 kcal per 100g they are slightly more calorie-dense than flat crisps due to increased oil absorption in the ridges.
A standard bag (25g) and a sharing bag (150g) contain very different amounts. A standard bag delivers 135 kcal and 0.45g of salt. A sharing bag delivers 810 kcal and 2.7g of salt, 45% 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.

Ultra-processed food: what is really in it
Seabrook Crinkle Cut Cheese & Onion is made from one main component: crinkle-cut potato crisps.
Reading the ingredient list closely, it contains flavourings and yeast extract. Flavourings create or enhance the taste of the product, often replacing or supplementing natural flavour sources to deliver a consistent result across batches. Yeast extract adds savoury depth and amplifies perceived saltiness without adding extra salt, a technique known as flavour enhancement.
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.
