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 — 15.6 g per 100 g (≥ 20% DV)
  • Low saturated fat — 0 g per 100 g (≤ 1 g)
  • Low sodium — 66 mg per 100 g (≤ 140 mg)
