Shoppers comparing labels
You check the fat content per 100 g rather than trying to work out what’s in a bag based on its size.
When comparing tortilla chips to limit fat, first check the values per 100 g for the exact variant: Carrefour and Auchan product listings show 20 g for SIMPL, Carrefour Sensation and Auchan plain, compared with 23 g for Doritos plain flavour 170 g at Auchan. This comparison alone isn’t enough to establish whether any of these products suit your goal; portion size, ingredients and allergens matter too.
You check the fat content per 100 g rather than trying to work out what’s in a bag based on its size.
You need to compare the values per 100 g with the amount you plan to eat, without assuming that a plain recipe automatically meets your goal.
You’re looking for a plain recipe and checking the ingredients list, stated allergens and storage instructions for the bag you choose.
Start with the fat content per 100 g, then check the portion you plan to eat and the exact recipe. These three checks answer different questions.
| Criteria | What to check | Who is it for? |
|---|---|---|
| Fat | Compare the fat content per 100 g for the exact variant. | If my main aim is to limit fat, the value per 100 g helps me distinguish between recipes without assigning them an overall nutritional rating; around 50% of consumers put this first. |
| Planned portion | Compare the amount you plan to eat with the nutritional values given per portion. | If I’m planning to eat more or less than the stated serving at a get-together, the amount I actually eat changes the comparison; around 30% of consumers prioritise this question. |
| Recipe and allergens | Read the ingredients and allergen declaration for the bag you choose. | If I choose a plain recipe but need to keep an eye on certain ingredients, the label for the exact variant is key; around 20% of consumers say this is their main concern. |
Carrefour and Auchan product listings show 20 g of fat per 100 g for several plain recipes. A lower value than another product doesn’t, by itself, mean it’s suitable for a diet where you’re limiting fat.
Compare the values per 100 g, then take into account the portion you plan to eat and your own dietary requirements.
Auchan product listings show 22 g of fat per 100 g for the 150 g organic plain variant, compared with 20 g for the 150 g plain variant.
Treat the organic label and nutritional values as separate pieces of information, and check the details for the exact variant.
Product listings for several plain recipes mention that they may contain traces of soya. Don’t assume that a different flavour or pack size has the same recipe as the one you’re checking.
Check the ingredients list, allergen declaration and nutritional information on the bag you choose.

This product is worth considering if you’re comparing fat per portion: the listing shows 6 g per 30 g. It also states that the product may contain soya and wheat (gluten). Check the exact variant and nutritional information on the bag, especially if you’re looking for a plain recipe.
Carrefour and Auchan product listings show 20 g of fat per 100 g for SIMPL, Carrefour Sensation and Auchan plain, compared with 23 g for Doritos plain flavour 170 g at Auchan. This comparison applies to these specific variants, not to all tortilla chips.
No. This value lets you compare labels, but it doesn’t determine on its own whether the product suits your goal. Also check the portion you plan to eat and the nutritional information on the exact bag. Manger Bouger recommends limiting foods that are high in fat and salt, as well as ultra-processed foods.
Check the ingredients, allergens and storage instructions for the variant you choose. Carrefour Sensation, SIMPL and Auchan plain listings, for example, mention that the products may contain traces of soya. Auchan advises keeping the bag away from heat and moisture and sealing it carefully after opening.
