How this ranking is made

7,118 products in the aisle declare fiber; 7,094 are ranked, leaving out 22 records above 24.0 g per 100 g (1.25 times the aisle's 99th percentile; a name or brand built on fiber or bran is exempt) or whose label declares more protein, fat and carbohydrate than its calories can hold; 2 named by the publisher's review (below) (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.

Left out after review:

  • Jupiter Rice Gritsrice grits declaring 194 calories per 100 g; dry rice grits run about 360, so the record does not match the product as sold
  • Purple Rice Gritsrice grits declaring 194 calories per 100 g; dry rice grits run about 360, so the record does not match the product as sold

Download: the top 250 as CSV (CC BY 4.0).

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.
