Is the glycemic index of products taken into account?

No, Mira doesn't take the glycemic index (GI) into account when rating products, and there are no plans to add it for now.

It would be a useful signal, but measuring GI reliably is almost impossible in practice. It isn't printed on packaging, so there's simply no way to source it when you're assessing thousands of products at scale.

GI also isn't a fixed number: it shifts noticeably depending on how a food is cooked and processed, how ripe it was, and what it's eaten alongside. The same dish can behave quite differently from one meal to the next, so there's no single trustworthy value to put on a label.

Mira does pay attention to sugar, though. In its nutritional assessment — built on Nutri-Score principles — a high sugar content lowers the rating and pushes a product into the lower bands, "Poor" or "Bad." That isn't the same as the glycemic index, but it helps surface products loaded with fast-digesting sugars.
