Corn flake cereals are made from white corn grits.
John Harvey Kellogg, a surgeon, vegetarian and health food pioneer, while superintendent at the Battle Creek Sanitarium, he developed the first breakfast cereals for his patients, Granose (flaked wheat) and toasted corn flakes. In 1884 he applied for a patent for 'flaked cereal' (corn flakes). His brother, William K. Kellogg founded the Battle Creek Toasted Corn Flake Co. to produce cornflakes for sale to the public.
In 1907, one of the ad campaigns for Kellogg's Corn Flakes (then the Battle Creek Toasted Corn Flake Company) offered a free box of cereal to every woman who would wink at her grocer.
