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:
- Low calorie — 36 kcal per 100 g (≤ 40)
- Low fat — 1.2 g per 100 g (≤ 3 g)
- Low saturated fat — 0 g per 100 g (≤ 1 g)
- Very low sodium — 16 mg per 100 g (≤ 35 mg)
