"Generally speaking, those who advocate health food sor natural foods subscribe to some of the same overall beliefs held by your physicians. They believe that diseases are the result of exterior conditions. Quite simply, their policy can be read: `You are what you eat.' Some in this group also subscribe to philosophical ideas that somewhat moderate those concepts, recognizing the importance of the mind. Often though, some strong suggestions of a very negative character are given, so that all foods except certain accepted ones are seen as bad for the body, and the cause of diseases. People become afraid of the food they eat, and the field of eating then becomes the arena. Moral values become attached to food, with some seen as good and some as bad. Symptoms appear, and are quite directly considered to be the natural result of ingesting foods on the forbidden list. In this system, at least, the body is not insulted with a bewildering assortment of drugs for therapy. It may, however, be starved of very needed nourishment. Beyond that the whole problem of health and illness becomes simplistically applied, and here food is scrutinized. You are what you think, not what you eat – and to a large extent what you think about what you eat is far more important. What you think about your body, health, and illness will determine how your food is used, and how your chemistry handles fats, for instance, or carbohydrates. Your attitudes in preparing meals are highly important. Physically, it is true, but again generally speaking, that your body needs certain nourishments. But within that pattern there is great leeway, and the organism itself has the amazing capacity to make use of substitutes and alternates. The best diet in the world, by anyone's standards, will not keep you healthy if you have a belief in illness."
