Nutri-Score is a rating system developed by international research teams that measures the nutritional value of food products.
To rank each product, the Nutri-Score system measures how much of the following is found in 100 grams of the product:
- desirable nutrients and foods: fiber, protein, fruits and vegetables
- nutrients that should be limited: calories, saturated fats, sugar and salt
The Nutri-Score calculation system is explained in detail here.
Once calculated, a product's score is used to assign it a letter and a color:
- the most nutritious products are ranked A
- the least nutritious products are ranked E
Nutri-Scores are translated into Yuka ratings as shown in the correspondence table, available here.
The main scientific sources evaluating the Nutri-Score are available here.
