Nutrient screening detail
The badges near the top of this page come from screening the per-100 g values against the FDA nutrient-content thresholds in 21 CFR 101.54–101.62. 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:
- Good source of protein — 7.3 g per 100 g (≥ 10% DV)
- Good source of fibre — 3 g per 100 g (≥ 10% DV)
- Low saturated fat — 0 g per 100 g (≤ 1 g)
- Sodium free — 0 mg per 100 g (< 5 mg)
- Sugar free — 0 g total sugars per 100 g (< 0.5 g)
