compare food labels consistently

Make food-label comparisons less arbitrary

Compare foods within the same category, use the same reference amount, and decide which label fields matter before you choose.

Worked two-product comparison: nutrition table, ingredient lists and FoodScore

Here is the complete comparison routine applied to two products in the grains-bread category: La Boulangère Bio Pain De Mie Bio (barcode 3760049790214) and Wasa Authentique crispbread (barcode 7300400481595). First, align the reference amount: because a single slice weighs 35.7 g for the soft bread and 11.4 g for the crispbread, compare the 100 g column and an equal 50 g portion (100 g value * 0.50).

Second, read the declared ingredient list alongside the numbers. Pain De Mie Bio starts with refined wheat flour (44%), water, whole wheat flour (13%), brown cane sugar, yeast and rapeseed oil, which brings sugars to 6.3 g per 100 g and fibre to 4.9 g per 100 g (FoodScore 45/100, poor). Wasa Authentique uses wholemeal rye flour (77 g per 100 g of product), rye flour (28 g per 100 g), yeast and salt without added sugar or oil, reaching 19.0 g of fibre and < 1 g of sugars per 100 g (FoodScore 79/100, good). Where Open Food Facts has no Czech ingredient translation (ingredients_text_cs) or check date, the record states that field as missing instead of estimating it.

A comparison needs a question before it needs a winner

Food labels offer a lot of numbers, which makes it easy to compare the wrong ones. One person looks at salt, another at fibre, while someone else notices the ingredient list first. None of those approaches is automatically better. The confusion starts when a product receives a sweeping good or bad label because one attractive figure stands out. A more useful comparison begins with a narrower question: what am I choosing between, and what information would actually separate these options?

Keep the category tight. Compare two tomato sauces, two breakfast cereals, or two plain yoghurts rather than asking whether a cereal is better than a sauce. Similar products serve similar roles, so their labels answer a comparable question. Next, choose a common reference amount. European food information legislation requires a nutrition declaration per 100 grams or 100 millilitres for many prepacked foods, which creates a practical common basis when that column appears. Per-serving figures can still help, but only when the portions are genuinely comparable.

Then read the panel in an order that reduces distraction. Start with the reference amount and the product form. A concentrated sauce, a ready-to-eat soup, and a dry mix should not be treated as interchangeable. Move to the fields you care about for that purchase, whether that is fibre, salt, protein, added sugars where declared, or another clearly labelled value. Finally, read the ingredient list and the package context. The first ingredient may tell you more about the product's character than a marketing phrase on the front.

Do not expect every decision to produce one clean winner. One cereal may have more fibre while another has a shorter ingredient list and a portion size that fits your breakfast better. That is not a failure of the comparison. It is the real trade-off. Write down or remember the reason you chose it, especially if you buy the product often. Over time, your own criteria become clearer and the aisle feels less like a quiz.

A compact routine works because it creates consistency without pretending that food choices are mathematical. Ask what job the product has. Compare like with like on a shared amount. Read the label fields relevant to that job. Check the ingredient list if it will influence your choice. Then decide. It takes less time than chasing every number, and it makes the choice easier to explain to yourself later.

Save effort for repeat decisions

You do not need a formal scorecard for a one-off purchase. The routine earns its value with products you buy repeatedly, because a settled comparison saves time on the next trip. Take a photo of the label if that helps, or simply remember why one option became your default. Revisit the choice when the packaging changes or a new alternative appears. This keeps the process practical: a label comparison is a small consumer decision, not a research project that has to be rebuilt every time.

Compare the version you can actually buy

Use the label on the shelf, not a remembered version of it. Brands can change a recipe, serving suggestion, pack size, or the way they present information, and an old favourite may no longer match the comparison you made months ago. When a package has changed, repeat the quick routine instead of assuming the old choice still applies. Read the product name carefully too, since a regular and a flavoured version can sit beside each other with almost identical branding. You only need a few minutes for a repeat purchase, especially after the first comparison taught you which fields matter. That small reset keeps your choice tied to the item you are taking home.

Common question

Should I always compare foods per serving?

Not always. A shared per-100-gram or per-100-millilitre basis can make similar products easier to compare.
