History fun fact! Graham crackers, and Graham flour in general was meant to kill boners.
Sylvester Graham invented Graham flour as an alternative to common white bread flour which he considered had no nutritional value and increased lust.
He was also a vegan since he considered animal products led to an increased sex drive.
Nowadays his theories about sex drive are held as bogus science, but his interest in the nutritional value of flour is held in high regard since flour additives used to bleach flour proved to be toxic and in general using all the grain is healthy.
