Graham crackers were invented to curb sexual urges and masturbation. The creator Sylvester Graham, a Presbyterian minister from Connecticut in the 1800s, invented the graham cracker to "cure" masturbation and other sexual urges. Graham believed that sexual desire caused headaches, epilepsy, and insanity, and that diet played a large role in these urges. He believed that people should eat only plants, like Adam and Eve in the Garden of Eden.
