The ZERO Score.
A 0–10 shopping aid. It compresses three numbers from the label into one, so you can rank a shelf at a glance. It is not a health rating, not medical advice, and it doesn't know your body.
Calories (up to 4 pts)
0 kcal earns full points; up to ~250 kcal earns partial points.
Sugar (up to 3 pts)
0 g earns full points; under 5 g earns partial points.
Protein (up to 3 pts)
15 g+ earns full points; 5 g+ earns partial points.
Category fairness
Drinks and sauces aren't expected to contain protein, so they're scored out of what their category can plausibly deliver. A perfect zero soda can score as well as a perfect protein bar.
Estimated scores ~8.7
When we have a researched figure from a citable source (brand published nutrition, Open Food Facts label data) but haven't re-checked the printed label ourselves, the score is computed from it and shown hollow with a “~”. The source is always named on the product page.
Unscored products ?
No citable figure at all → no score, just a “?”. We'd rather show a question mark than punish a product for our missing data, and we never fill in numbers we don't have: missing data is shown as “—”.
