“The whiter your bread, the sooner you’re dead”

“The whiter the bread, the sooner you’re dead” is a saying that was started in the Daily Mail (London) on July 21, 1924. The saying (also given as “the quicker you’re dead”) has been frequently used to get people to eat other breads, such as multi-grain bread.
 
American radio personality R. P. L. Clark announced over a Chicago radio station in 1928: “The whiter the bread, the sooner you’re dead; The whiter the flour, the sooner the flowers.”
