Caries results from inadequate nutrition, which, by unfavorably influencing endocrines, (a) affects calcium-phosphorus levels in the blood, these (b) re­flecting susceptibility or immunity to caries, (c) indicating the efficiency of the related metabolic processes, and (d) suggesting treatment necessary for correction of abnormal levels. Adequate nourishment does not of itself cor­rect abnormal calcium/phosphorus levels ; but adequate diet, supplemented with proper endocrine treatment, does so promptly. ” Proper endocrine treatment ” is based upon classification of the individual as to dominance of sympathetic or parasympathetic divisions of the autonomic nervous system. Correct interpretation of the calcium/phosphorus levels of blood plasma serves as an accurate ” measuring stick ” of ” body chemistry,” and indicates that caries and other degenerative processes, such as cataract and arthritis, as well as localized environmental factors in the mouth, are results of imperfect body chemistry and hence are of systemic origin.

A study of about 4000 analyses of blood plasma, and the histories of the per­sons for whom they were made, showed that ” adequacy ” in diet is not the same for everyone ; that prevention of caries is a different problem for each individual. Study of the diet of the racial group from which a person takes his predominant characteristics is of great value for determination of his dietary requirements. Likewise ” inadequate ” diet does not affect all people in the same manner. Thus, brothers may respond very differently to inadequate diet—one may have caries, the other may be immune ; yet the body chemistry may be equally disturbed in both cases. The one who is free from caries may be susceptible to an entirely different pathology. This the author has termed ” pathological immunity ” to caries. Fail­ure to recognize this phenomenon has been responsible for much confusion among researchers.
