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:

• High protein — 10 g per 100 g (≥ 20% DV)
• High fibre — 5.8 g per 100 g (≥ 20% DV)
• Sodium free — 0 mg per 100 g (< 5 mg)
• Sugar free — 0 g total sugars per 100 g (< 0.5 g)
