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 — 19 g per 100 g (≥ 20% DV)
- Low fat — 0.9 g per 100 g (≤ 3 g)
- Low saturated fat — 0.2 g per 100 g (≤ 1 g)
- Sugar free — 0 g total sugars per 100 g (< 0.5 g)
- Keto-friendly — 0.1 g net carbs per 100 g (≤ 5 g)
