A Nutri-Score for a particular food item is given in one of five classification letters, with 'A' being a preferable score and 'E' being a detrimental score. The calculation of the score involves seven different parameters of nutrient information per 100g of food which are usually available on food packagings. High content of fruits and vegetables, fibers, protein and healthy oils promote a preferable score, while high content of energy, sugar, saturated fatty acids, and sodium promote a detrimental score. In addition to the general calculation rules applied to most types of food, there are special rules for cheese, for “added fats” and for beverages.
