Corn Flakes cereal
Corn flakes, or cornflakes, are a breakfast cereal made from toasting flakes of corn . Originally invented as a breakfast food to counter indigestion, it has become a popular food item in the American diet and in the United Kingdom where over 6 million households consume them. The cereal, originally made with wheat, was created by Will Kellogg in 1894 for patients at the Battle Creek Sanitarium where he worked with his brother John Kellogg who was the superintendent. The breakfast cereal proved popular among the patients and Kellogg subsequently started what became the Kellogg Company to produce corn flakes for the wider public. A patent for the process was granted in 1896, after a legal battle between the two brothers.
