The Nutri-Score calculation method has been refined in the Yuka rating in order :

- to avoid threshold effects that could lead to significant rating differences between two products with similar nutritional values,
- to prevent a product with a Nutri-Score of D or E from having a score higher than 49/100 in the Yuka rating.

The correspondence table below details how Yuka turns a five-letter Nutri-score to a score out of 100. This is used for rating the nutritional quality of a product.
