How these rankings work
Every figure is per 100g, taken from the label as recorded in Open Food Facts, the open food database built by volunteers. Products whose numbers don't add up (for example, energy that doesn't match the fat, carbs and protein) are left out of these tables but still appear in the full aisle. Traffic lights follow the UK front-of-pack thresholds for fat, saturates, sugar and salt. Nutri-Score runs from A (best) to E. Brands can't pay to appear here. Spot a mistake? Fix it at the source on Open Food Facts and it reaches Shelf Check at the next refresh.
