John Harvey Kellogg invented his famous Corn Flakes cereal expressly to do what?

John Harvey Kellogg (February 26, 1852 – December 14, 1943) was a major leader in progressive health reform, particularly of the clean living movement. He wrote extensively on science and health. His approach to "biologic living" combined scientific knowledge with Adventist beliefs, promoting health reform, temperance and sexual abstinence. His promotion of developing anaphrodisiac foods was based on these beliefs.

Many of the vegetarian foods that Kellogg developed and offered his patients were publicly marketed: Kellogg is best known today for the invention of the breakfast cereal corn flakes, originally intended to be an anaphrodisiac, made by his brother, Will Keith Kellogg. His creation of the modern breakfast cereal changed "the American breakfast landscape forever."
