"You are what you think you are." far more true than “You are what you eat.”

Concerning the diet: you already realize what the situation is. If you firmly believe that certain items in a diet will cause you distress, then of course they will—and avoiding the same items will bring relief.

Many times people at the point of desperation seize upon such ideas, and often they are valuable because they relieve people of hidden guilts; they are not "to blame" for their difficulties—but certain elements outside of their own selves are the culprits.

Such diets may work. Just the relief from guilt feelings alone would result in an upsurge of bodily health and enthusiasm. Everyone reacts to food differently. Even while it carries a great resemblance to any other physical body, still a body's own individualistic characteristics are such that for all the likenesses to other bodies, few generalizations can be safely made.

Ruburt felt some dismay when you told him of the letter about the diet because he felt momentarily threatened—attracted to the diet, and suspicious of it at the same time. It seemed to be just like one of the many so-called cures that raised hopes only to dash them.

Again, according to your belief structure, such diets can be extremely beneficial, particularly in the short run—but if the person involved forever places their belief in such exterior conditions, then they will feel themselves to be victims, and the charm of the diet may begin to lose its strength. Or they must become more and more rigorous in following it, or they may discover that more and more foods seem to cause their distress.

Man cannot assign his own psychology to the food that he partakes.

"You are what you think you are." That statement is far more to the point than the one that says, "You are what you eat."

"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.

A belief in health can help you utilize a "poor" diet to an amazing degree. If you are convinced that a specific food will give you a particular disease, it will indeed do so. It appears that certain vitamins will prevent certain diseases. The belief itself works while you are operating within that framework, of course. A Western doctor may give vitamin shots or pills to a native child in another culture. The child need not know what particular vitamin is being given, or the name for his disease, but if he believes in the physician and Western medicine he will indeed improve, and he will need the vitamins from then on. So will all the other children."
