Nutrient screening detail

The regulations define those claims per reference serving rather than per 100 g, so treat these as a like-for-like comparison between foods, not as a statement about a product label:
- Low sodium — 50 mg per 100 g (≤ 140 mg)
- Sugar free — 0 g total sugars per 100 g (< 0.5 g)
