" One of the patients at Kellogg’s Seventh-day Adventist sanitarium was C. W. Post, who got the idea there for Grape Nuts, which made him rich. Among Grape Nuts’ advertised health benefits was curing appendicitis. As it happened, Post later had an apparent appendicitis attack, and when surgery didn’t end his distress, he shot and killed himself. "
