Onion nutrition label for Canada, the EU and the UK
The same 1 cup, chopped of onion, drawn by the site's Canadian, EU and UK renderers. Canada keeps a per-serving panel in English and French with its own Daily Values and folds trans fat into the saturated-fat row. The EU declaration is per 100 g only, states energy in kJ and kcal, and declares salt (sodium × 2.5) rather than sodium. The UK table is the EU layout as retained by the Food Information Regulations 2014, with the optional per-serving column and %RI. One recipe in the generator renders all of them from the same numbers.

What stands out in onion
Measured against the FDA's nutrient-content claim thresholds (21 CFR 101.54), onion is notable for:
- Fiber - 3g per 1 cup, chopped - 10% DV, enough to qualify as a good source (10–19% DV).
These are the thresholds that decide whether a package may carry a claim like “good source of fiber”. The label generator applies the same rules to your own recipe.
