Though our moral philosophers have differed in many details, especially in regard to
the sources of moral judgment, they have agreed amazingly in regard to what men ought to do.
These include obsessive focus on food choice, planning, purchase, preparation, and consumption; food regarded primarily as
source of health rather than pleasure; distress or disgust when in proximity to prohibited foods; exaggerated faith that inclusion or elimination
of particular kinds
of food can prevent or cure disease or affect daily well - being; periodic shifts in dietary beliefs while other processes persist unchanged;
moral judgment of others based on dietary choices; body image distortion around sense
of physical «impurity» rather than weight; persistent belief that dietary practices are health - promoting despite evidence
of malnutrition.
