Crisps are not health food. That’s the honest answer, and anyone selling you a bag of crisps should probably admit it upfront.
But the full picture is more interesting than a flat no. Some crisps are genuinely better than others, the differences between brands and formats are significant, and eating crisps in reasonable quantities as part of a normal diet is not the nutritional disaster it’s sometimes made out to be.
The question worth asking isn’t really “are crisps healthy” but “which crisps are worth eating and how much is too much.”
What’s Actually in a Bag of Crisps
Calories and Fat
A standard 25-30g bag of potato crisps contains roughly 130 to 160 calories and between 8 and 10 grams of fat. That’s not enormous for a snack, but it adds up quickly if you’re eating multiple bags or treating a large sharing bag as a single portion. The calorie count varies noticeably between brands and styles: baked crisps tend to be lower in fat than fried, and lighter formats like Quavers or Skips come in at fewer calories per bag than a denser crisp like McCoy’s.
Always check the per-bag figure on the back rather than per 100g. Per 100g looks alarming for almost everything.
Salt Content
Salt is where crisps take the most criticism, and it’s fair. A standard bag can contain between 0.3g and 0.6g of salt, which is a meaningful chunk of the recommended daily maximum of 6g for adults. Flavoured varieties tend to have more salt than ready salted, and thicker crisps often carry heavier seasoning than lighter formats.
If salt is a concern, looking at the traffic light labelling on the front of the pack is the fastest way to compare. Anything showing green or amber for salt is a reasonable choice. Consistent red across the board is worth paying attention to.
Ingredients: What to Look For
The ingredient list on a crisp packet tells you a lot. Shorter lists with recognisable ingredients are generally a better sign than long lists with additives and flavour enhancers. Crisps made with sunflower oil or olive oil are preferable to those using palm oil or partially hydrogenated fats. Some brands, particularly premium ranges, use fewer ingredients than the big mainstream names, though they typically cost more per bag.
Which Crisps Are the Better Choice
Baked vs Fried
Baked crisps generally contain 30 to 50 percent less fat than fried equivalents. Brands like Walkers Baked and various own-label baked ranges exist specifically to offer a lower-fat alternative without abandoning the crisp format entirely. The trade-off is texture: baked crisps are lighter and less satisfying to some people, which can mean eating more of them to feel the same level of fullness.
Lighter Formats
Corn and rice-based snacks often have a lower calorie count per bag than potato crisps because they’re puffed rather than fried. Skips are a good example: a standard bag is around 72 calories, which is significantly lower than most potato crisps. Quavers are similar. These formats tend to suit people watching calories more than people watching fat or salt, as the sodium levels can still be comparable to a standard crisp.
Vegetable and Lentil Crisps
The vegetable crisp category has expanded considerably in recent years. Lentil-based snacks and chickpea puffs carry more protein and fibre than potato crisps, which does make them a more nutritionally complete snack. They’re not salad, but they’re a more considered choice if you’re trying to add something beyond empty calories to your diet.
Crisps and a Balanced Diet
What Moderation Actually Means
One bag of crisps a day is not going to derail an otherwise reasonable diet. The problem comes with portion sizes and frequency. A single 25g bag is a snack. A 150g sharing bag eaten alone in front of the television is a different proposition entirely, and the calorie and salt intake from that is genuinely significant.
The practical approach is to treat crisps as a deliberate snack rather than something you eat automatically. One bag, not the whole multipack. That’s not a particularly radical position, but it’s the one that lets you enjoy crisps regularly without any real dietary concern.
Crisps vs Other Snacks
Compared directly to chocolate or biscuits, crisps tend to be lower in sugar and sometimes comparable or lower in calories per portion. The crisps vs chocolate comparison is more interesting than most people expect. Neither is a health food, but crisps don’t deserve their reputation as the worse option in every comparison.
Compared to nuts or seeds, crisps lose on nutritional value. Nuts offer protein, healthy fats, and micronutrients. Crisps mostly offer carbohydrates and salt. If you’re choosing a snack for actual nourishment, nuts win. If you’re choosing a snack because you want a crisp, eat a crisp.
Vegan and Gluten Free Options
Are Crisps Suitable for Dietary Requirements?
Many crisps are naturally vegan and many are gluten free, but this varies considerably by brand and flavour. Cheese and onion flavours often contain dairy. Beef and prawn cocktail flavours may not be vegan. Some crisps are produced in facilities that handle wheat, which matters for people with coeliac disease.
The best vegan crisps UK guide covers which brands and flavours are plant-based. The gluten free crisps guide covers the safe options for people avoiding gluten. Always check the current packet rather than relying on older information, as recipes do change.
Crisps with Fewer Additives
If artificial flavourings and additives are a concern, premium crisp brands like Pipers Crisps tend to use simpler ingredient lists and natural flavourings. They cost more, but the ingredient quality is noticeably higher. For everyday snacking, mainstream brands are fine. For people who want to be more deliberate about what they’re eating, the premium end of the market is worth considering.
Crisps occupy a specific place in British food culture that no amount of nutritional analysis is going to shift. The sensible approach is to know what you’re eating, choose better options where they exist, and not treat every bag as a moral failing.

Are crisps bad for you?
Eaten occasionally and in normal portion sizes, crisps are not bad for you. They’re high in fat and salt relative to their weight, so eating large quantities regularly is worth avoiding, but one bag a day as part of a balanced diet is not a significant health concern for most people.
Which crisps are the healthiest?
Baked crisps are lower in fat than fried. Lighter formats like Quavers and Skips are lower in calories per bag. Lentil and chickpea-based snacks offer more protein and fibre than potato crisps. The best choice depends on whether you’re prioritising calories, fat, or nutritional content.
How many calories are in a bag of crisps?
A standard 25-30g bag of potato crisps contains roughly 130 to 160 calories. Lighter formats like Quavers or Skips can be as low as 70 to 90 calories per bag. Larger grab bags and sharing bags are significantly higher.
Are crisps high in salt?
Yes, most crisps contain a meaningful amount of salt. A standard bag typically contains 0.3g to 0.6g of salt. Flavoured varieties tend to be saltier than ready salted. Checking the traffic light labelling on the front of the pack is the quickest way to compare brands.
Are baked crisps healthier than fried?
Baked crisps generally contain 30 to 50 percent less fat than fried equivalents. The calorie difference is meaningful if you’re monitoring fat intake. Salt levels can be similar, so baked is not automatically a lower-sodium choice.
Are crisps vegan?
Many crisps are vegan, but not all. Cheese-flavoured varieties usually contain dairy. Some flavourings use animal derivatives. The best vegan crisps UK guide on this site covers which brands and flavours are plant-based.
