" Fletcher believed—decided, really—that by chewing each mouthful of food until it liquefies, the eater could absorb more or less double the amount of vitamins and other nutrients. “Half the food commonly consumed is sufficient for man,” he stated in a letter in 1901. Not only was this economical—Fletcher estimated that the United States could save half a million dollars a day by Fletcherizing—it was healthier, or so he maintained. By delivering heaps of poorly chewed food to the intestine, Fletcher wrote, we overtax the gut and pollute the cells with the by-products of “putrid bacterial decomposition.” While other feces-fearers of the day advocated enemas to speed food through the putrefaction zone (and more on this in chapter 14), Fletcher advised delivering less material.
