the.com/bran flake

means A flat, toasted flake made from the bran (outer husk) of wheat, eaten as a fiber-heavy breakfast cereal.

from Compound of 'bran,' from Old French 'bran' or 'bren' meaning the husk of grain separated from flour, and 'flake,' a Middle English word for a small flat piece or layer, related to Old Norse 'flak.' The cereal itself is a product of the late 19th-century breakfast-food movement, when manufacturers began marketing bran — once mostly animal feed or milling waste — as a fiber-rich health food for humans.
