How to copy a nutrition label into a food log
By Juste Tools · Published
Before copying a nutrition label into a log, check what quantity its numbers describe. The basis may be one serving, 100 grams or the whole packet. Matching the quantity and unit prevents a basic recording error; it does not tell you what you should eat.
Find the basis first
Look for the serving size or the heading above the numerical column. A packet can contain more than one serving, and a label can show several columns. Choose the column that matches the information you intend to record.
- Keep grams, millilitres and servings distinct.
- Check whether the value describes prepared or unprepared food.
- Copy the product name so you can recognise the source later.
Use a transparent calculation
If a hypothetical label lists 120 units per 100 grams and your recorded amount is 150 grams, the matching calculation is 120 × 150 ÷ 100 = 180 units. If a value is per serving and you record two equal servings, multiply that value by two.
These are arithmetic examples, not recommended portions, targets or a claim about any specific product. Keep the source and assumption with the entry so another person can understand the calculation.
Review a scan or search result
A scan or database match can still need checking. Compare the product, quantity basis and visible values with the packet you have. Do not assume an app reads every label type or recognises every product. When information is missing, record the gap rather than silently filling it with a guessed exact number.
