Why this label?

High Protein

67.3 g protein for 1160 kcal = 5.8 g per 100 kcal, so protein gives about 23% of the energy. High Protein needs at least 20% (5 g per 100 kcal), the condition in the Annex to EU Regulation (EC) No 1924/2006. How we decide

EU nutrition claims

  • Low sugars: 4 g sugars per 100 g (limit ≤ 5 g)

Per 100 g of the finished dish, worked out from the nutrition per serving and the lowest likely cooked weight (about 341 g a serving), so the true values are, if anything, lower. Thresholds from the Annex to EU Regulation (EC) No 1924/2006. How we decide
