To choose lower-calorie crisps, compare the energy values on a like-for-like basis, then work out how much energy there is in the portion you plan to eat. Among the recipes listed on Carrefour France, Lay’s Nature Cuites au Four contains 133 kcal per 30 g, or around 443 kcal per 100 g. That compares with 467 kcal per 100 g for Carrefour Classic’ allégées and 470 kcal per 100 g for Vico La Légère. A no added salt recipe meets a different need; for budget-friendly shopping, also choose a pack size that suits how much you’ll eat.
You’d rather check the figures than rely on the word ‘light’. Carrefour France lists Lay’s Nature Cuites au Four at 133 kcal per 30 g, while Vico La Légère is listed at 470 kcal per 100 g. Convert the figures to the same quantity before comparing them.
You’re looking for a pack that matches the amount you plan to serve. Check its weight and how much you’ll actually eat: a smaller bag doesn’t, by itself, change the nutritional values per 100 g.
Your priority is salt rather than calories. Check the ‘salt’ line in the nutritional information and the ingredients list. A ‘no added salt’ claim alone doesn’t tell you how much energy the product contains.
Start with the reason you’re buying, then check separately how much you’ll eat and the other nutritional values.
| Criteria | What to check | Who is it for? |
|---|---|---|
| Energy and fat | Compare kcal and fat per 100 g, then check the kcal in the portion you plan to eat. | If I’m choosing lower-calorie crisps for a snack, I want to compare recipes without confusing the serving size with the reference weight. Around 50% of consumers prioritise comparing energy and fat. |
| Pack size | Check the pack weight and decide how much you plan to serve. | When planning my shopping, I’d rather choose a pack that matches the amount I’ll eat than have most of it left open. Pack size is the main consideration for around 30% of consumers. |
| Salt | Check the ‘salt’ line and the ingredients, then look at kcal separately. | If I’m mainly looking for a no added salt recipe, I don’t want to assume that it contains fewer calories. Around 20% of consumers check salt first. |
According to its Carrefour France product listing, Carrefour Classic’ sans sel ajouté contains 532 kcal and 34 g of fat per 100 g. A claim about salt doesn’t tell you the product’s energy value.
Check the ‘salt’, ‘energy’ and ‘fat’ lines separately for the specific product you’re considering.
The 133 kcal per 30 g listed for Lay’s Nature Cuites au Four can’t be compared directly with the 470 kcal per 100 g listed for Vico La Légère on Carrefour France.
First convert the figures to the same quantity: 133 kcal per 30 g is around 443 kcal per 100 g. Then work out the kcal in the portion you plan to eat.
Auchan France lists vegetables, sunflower oil and salt among the ingredients in Auchan Collection vegetable crisps. The product name alone isn’t enough to compare their energy value with that of potato crisps.
Check the nutritional values per 100 g on each pack before deciding.
The Nature Cuites au Four recipe is different from the brand’s classic plain crisps, thanks to its advertised cooking method. Its Nutri-Score B appears on Carrefour France’s product listing, but you should still check the nutritional values.

Pringles Original is a tube of stackable potato crisps, so it’s different from the reduced-fat crisp recipes covered here.

This 150 g pack is for anyone looking for bruschette crisps in a Sour Cream & Onion flavour. They’re not potato crisps, so check the nutritional values per 100 g and your intended portion before comparing them with other recipes.
The claim alone doesn’t tell you: check the energy value per 100 g for each recipe. Carrefour France lists Carrefour Classic’ allégées at 467 kcal per 100 g and Vico La Légère at 470 kcal per 100 g. Lay’s Nature Cuites au Four is listed at 133 kcal per 30 g, or around 443 kcal per 100 g.
Not necessarily. Carrefour France lists Carrefour Classic’ sans sel ajouté at 532 kcal per 100 g. Check the energy value of the recipe, even if salt is your main concern.
No. The DGCCRF describes the Nutri-Score as a voluntary, supplementary label. When comparing two packs, use their nutritional information, particularly the energy, fat and salt values per 100 g.
The name alone doesn’t tell you. Auchan France’s listing for Auchan Collection vegetable crisps includes sunflower oil among the ingredients. Check the energy value of the specific product and compare it per 100 g before choosing.
