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 — 21.5 g per 100 g (≥ 20% DV)
  • Low sodium — 46 mg per 100 g (≤ 140 mg)
  • Sugar free — 0 g total sugars per 100 g (< 0.5 g)
