The namesake of the graham cracker is a Presbyterian minister who claimed that overeating could not only make you fat, it could make you lecherous, too. Sylvester Graham ran health retreats during the 1830s for like-minded parishioners featuring a strict meat-free, bland diet. It must work, because you do not see many lechers running around eating graham crackers. Although I love them with peanut butter and jelly. Mmmm!
