Understanding Fat in Crisps
Traditional potato crisps are typically fried in oil, which significantly contributes to their overall fat content. The process of deep-frying saturates the potato slices with oil, increasing both their total fat and calorie count. In contrast, many newer and healthier crisp alternatives use different cooking methods, such as baking, air-popping, or kettle-cooking with more stable, less-processed oils. These methods can drastically reduce the amount of absorbed fat, offering a lighter, less greasy snack experience.
The Difference: Baked vs. Fried Crisps
It is a common misconception that all baked snacks are inherently healthy. While baked crisps generally contain less fat than their fried versions, some brands may compensate for the reduced oil by adding extra starches, sugars, and flavour enhancers to improve taste and texture. This can result in a snack that is not as nutritionally superior as one might assume. For example, some baked chips have shown to have double the sugar of their regular counterparts. Therefore, it is crucial to read nutritional labels carefully rather than simply relying on a "baked" or "low-fat" label. Factors like the type of oil and the amount of sodium are also important considerations.
Popular Low-Fat Crisp Options
Here is a list of popular crisps and their fat content, based on available nutritional information. These products are often lower in fat compared to standard potato crisps.
- Walkers Baked: These are oven-baked rather than fried, and a standard bag of Sea Salt flavour contains only 3.4g of fat and 109 calories.
- Quavers: These curly potato snacks are notably low in fat, with a standard bag containing around 4.9g of fat and 88 calories.
- Skips: With their unique prawn cocktail flavour, Skips are a low-calorie and low-fat option, containing approximately 4.6g of fat per bag.
- Popchips: Made using a popping technique that involves heat and pressure, Popchips offer a popular, lower-fat alternative to traditional crisps. The company states they contain significantly less fat than standard fried chips.
- Properchips (Lentil Chips): Made from protein-rich lentils, Properchips are another baked option that is lower in fat than standard potato crisps.
- Lentil Crisps (Eat Real): These are made from lentil flour and are often marketed as a healthier snack. Some variations, like Eat Real Lentil Chips, can be up to 48% lower in fat than typical potato crisps.
- Hippeas Chickpea Puffs: As the name suggests, these are puffs made from chickpeas. They are baked, gluten-free, and generally low in fat, with some flavours containing less than 100 calories per bag.
- Veggie Straws (Eat Real): Made from a blend of vegetables, these straws offer a lower-fat option and are often free from common allergens.
Making Your Own Lower-Fat Crisps
For maximum control over ingredients, making your own crisps at home is an excellent option. Using an air fryer or oven-baking thinly sliced vegetables allows you to control the type and amount of oil used. Popular choices for homemade crisps include:
- Sweet Potato: Baked sweet potato crisps can be a delicious and nutritious option. A plain, baked version is naturally very low in fat.
- Kale: By simply tossing kale leaves with a little oil and seasoning, you can create a super-healthy, crispy snack.
- Beetroot and Parsnip: These root vegetables also bake well and offer a colourful, lower-fat alternative.
- Popcorn: Air-popped popcorn, lightly seasoned, is a whole grain and naturally low in fat.

Conclusion: Navigating Low-Fat Crisp Choices
When seeking out low-fat crisps, it's vital to look beyond simple claims and delve into the nutritional details. While baked and popped varieties generally offer a lower-fat option than traditional fried crisps, checking the specific fat, saturated fat, and sodium content per serving is the best strategy. For the ultimate control over ingredients and fat levels, consider making your own vegetable crisps or air-popping popcorn at home. By combining careful label-reading with an awareness of manufacturing techniques, you can make smarter, healthier choices to satisfy your craving for a savoury, crunchy snack.
