This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
Nutri-Score, the Nordic Keyhole and Finland's Heart Symbol are all published rule sets, so a person can check a pack instead of trusting the letter on it.
A page per scheme carries the actual point table and qualifying criteria, a calculator that scores any food from its label, and the category-specific rules for drinks, fats and cheese; further pages cover what the 2023 Nutri-Score revision changed and the honest criticisms, including where the score rewards reformulation over whole foods and where two near-identical products land in different bands. Fourteen pages with three working calculators, and the Finnish Heart Symbol has no decent explainer anywhere.
How to use it
Use Front-of-pack scores: the algorithms, worked as a structured learning path: begin with the vocabulary, follow the evidence map, and keep the uncertainty labels attached to claims as you compare sources.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
Search vocabulary in four languages
Terminology changes across borders. These are example phrases people use for the same subject in Estonian, Finnish, Russian and English; they are included as a practical vocabulary aid, not as hidden keywords.
| Language | Example phrase |
|---|---|
| Estonian | nutri-score selgitus kuidas arvutatakse |
| Finnish | sydänmerkin kriteerit |
| Russian | нутри-скор как рассчитывается |
| English | how is nutri-score calculated |
Evidence and provenance
The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.
Source: the published Nutri-Score algorithm and the 2023 update report of the transnational scientific committee, the Nordic Keyhole regulation, and the Finnish Heart Association's published Heart Symbol criteria. · checked 2026-09-09
Source names are preserved even where an authority changes its web address. No figure is added to this launch page unless it is already present in the cited source description or can be computed from a named dataset.
Scope and boundaries
This guide owns the explanatory layer for the topic. Personal decisions, diagnoses, legal determinations and live availability remain with the relevant professional or official service.
