Horace Fletcher (1849-1919) was known as “The Great Masticator'' a dubious title. The foodie earned this appellation because of his practice and advocacy of chewing food until liquified before swallowing. IMHO, this is excellent advice, unlike his promotion of low protein, high carb diets. Oh well.
One surprising, if not gross, interest of his was poop. But believe it or not, these days the Bulletproof people also want us to study Number Two as a means to improve our health. I will blog about that soon.
From Wikipedia: His mastication system became known as "Fletcherism".
Fletcher and his followers recited and followed his instructions religiously, even claiming that liquids, too, had to be chewed in order to be properly mixed with saliva. Fletcher argued that his mastication method will increase the amount of strength a person could have while actually decreasing the amount of food that he consumed. Fletcher promised that "Fletcherizing", as it became known, would turn "a pitiable glutton into an intelligent epicurean”...
...He believed that the only true indication of one’s nutrition was evidenced by excreta (Fletcher 142). Fletcher advocated teaching children to examine their excreta as a means for disease prevention (Fletcher 143). If one was in good health and maintained proper nutrition then their excreta, or digestive "ash", as Fletcher called it, should be entirely "inoffensive". By inoffensive, Fletcher meant that there was no stench and no evidence of bacterial decomposition.
