Compare two country versions of a food without merging their labels
Use separate market records and an explicit crosswalk to compare same-brand packages from different countries.
Two packages with the same brand and product name should still have separate records when they come from different markets. Start by recording what each package says. Do not assume either identical recipes or different recipes simply from the country shown.
Build one record per market version
Give each package a reference containing the market, flavor and net quantity. Attach its ingredient photograph and nutrition photograph. Record the language of the panel you transcribed. If an import sticker adds information, keep that as an additional source rather than overwriting the underlying package image.
For a hypothetical comparison, label the records oat-bites-US-150g and oat-bites-EU-150g. The matching pack sizes help identification but do not prove that ingredient wording or nutrient values are the same. Read those fields independently.
Translate the basis before comparing values
US panels commonly state nutrients for a serving, while EU declarations use a 100 g or 100 ml basis. See the FDA serving explanation and European Commission nutrition guidance. Keep the original basis in each record even after calculating a shared one.
Suppose the fictional US package gives 3 g of total sugars per 30 g and the EU package gives 10 g of sugars per 100 g. The arithmetic for the first record is 3 ÷ 30 × 100 = 10 g per 100 g. These displayed values align numerically at that basis. That finding alone does not establish identical recipes, laboratory results or label definitions for every category.
Create a field-by-field crosswalk
Use separate rows for the printed nutrient name, printed amount, unit, basis and derived common-basis value. Where categories differ, write not directly aligned and research their definitions before comparing. Sodium and salt, for example, require more work than translating the word beside the number.
For ingredients, preserve each full list in its original language and place your translation in a neighboring field. Do not alphabetize the original lists or merge synonyms automatically; doing so destroys evidence about wording and order.
Conclude with specific observations: the two displayed sugar values match after normalization; the ingredient lists need further terminology review; one panel lacks a comparable field. Avoid a broad statement that one country's version is healthier. A careful crosswalk gives you useful differences without inventing a reason for them.
