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 only seven different parameters of nutrient information per 100g of food which are usually available on food packagings. High content of fruits and vegetables, fibers, and protein promote a preferable score, while high content of energy, sugar, saturated fatty acids, and sodium promote a detrimental score.[12]
