How does Mira adapt the Nutri-Score system?

Mira builds on the principles of Nutri-Score but refines them so that nutritional quality is assessed more precisely and isn't thrown off by abrupt category thresholds. The adaptation does two things:

• it smooths out threshold jumps — so two products with almost identical composition don't end up with sharply different ratings just because one barely crossed a category boundary;

• it keeps nutritionally weak products from being overrated — products that Nutri-Score treats as the least nutritious stay in the lower bands in Mira and can't climb into the top bands on nutrition alone.

Instead of fixed letter grades, Mira translates nutritional quality onto a smooth scale that is adapted to the product type (regular food, beverages, cheeses, fats and oils, water). That is what the correspondence table below illustrates.

Nutritional quality is one factor in the rating, alongside food additives and organic status. The riskiest factor sets the ceiling: even strong nutrition won't push a product into the top bands if a high-risk additive is present.

Mira's rating bands are Excellent, Good, Poor and Bad. The rating is Mira's opinion: the words "Excellent", "Good", "Poor" and "Bad" refer to the rating, not to the product itself.
