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 fat — 1.1 g per 100 g (≤ 3 g)
- Low saturated fat — 0.6 g per 100 g (≤ 1 g)
- Low sodium — 93 mg per 100 g (≤ 140 mg)
- Sugar free — 0 g total sugars per 100 g (< 0.5 g)
- Keto-friendly — 4.8 g net carbs per 100 g (≤ 5 g)
