How this ranking is made
6,635 products in the aisle declare calories; 978 are ranked, leaving out 54 mixes, powders or concentrates; 8 records whose label contradicts itself or that sit outside the aisle's range; 5,595 that do not declare all seven core label values (each rule). Values are per 100 g as each manufacturer submitted them to USDA, one product per UPC (its newest submission that meets the data contract), and one per product sold under several UPCs with the same label. The top 100 are shown; each was read again from USDA's live record at this release, and USDA's corrections are applied.

What this ranking does not measure
Taste, price, where it is sold and whether the recipe changed since the manufacturer's last submission. Each product page shows the date of its record.
