What is the fat ratio?

Mira has no separate "fat ratio" criterion. The idea comes from nutrition-labelling methods, but in Mira's rating there's no standalone axis for it.

Oils, margarines and butter fall into Mira's fats category, where their nutritional quality is assessed using Nutri-Score principles adapted to this product type. In this category, a high share of saturated fat weighs most heavily on the rating — which is why products rich in it tend to land in the lower bands ('Poor'/'Bad').

The underlying idea is sound: for your health, what matters isn't only the total amount of fat but how much of it is saturated. Saturated fat plays a role in the body, yet too much of it in the diet is linked to a higher risk of cardiovascular disease, and modern eating habits often include far too much. Mira simply factors this into the fats rating rather than reporting it as a separate metric.

Beyond nutritional quality, the final rating is shaped by two more factors: the additives in the composition and whether the product holds a verified organic certification. The sources behind each factor are shown on the product page in the app.
