How this ranking works
Products are ordered by their GoodSwap score, the same 0–100 score and receipt the app shows: ingredients, processing and nutrition, with every point tied to a source. Only products sold in the US whose score has medium or high confidence are ranked, and a tie goes to the more-scanned product. A score can change when a recipe or our published method changes; each product page shows the versions behind its number.
