Energy

EU/UK energy is recalculated from macronutrients with the Annex XIV factors (carbohydrate 17 kJ, protein 17 kJ, fat 37 kJ, fibre 8 kJ, alcohol 29 kJ per g). USDA carbohydrate is "by difference" and includes fibre, so EU carbohydrate values may be slightly higher than an EU-style analysis. US calories use USDA values.

Salt

Salt = sodium × 2.5.
