The accidental legacy of corn flakes goes back to the late 19th century, when a team of Seventh-day Adventists began to develop new food to adhere to the vegetarian diet recommended by the church. Members of the group experimented with a number of different grains, including wheat, oats, rice, barley, and corn. In 1894, Dr. John Harvey Kellogg, the superintendent of The Battle Creek Sanitarium in Michigan and an Adventist, used these recipes as part of a strict vegetarian regimen for his patients, which also included no alcohol, tobacco, or caffeine. The diet he imposed consisted entirely of bland foods. A follower of Sylvester Graham, the inventor of graham crackers and graham bread, Kellogg believed that spicy or sweet foods would increase passions.
