The purpose of the experiments was to determine whether the carbohydrate contained in Jerusalem artichoke is more available for the nutrition of certain subjects with severe diabetes than equal quantities of other carbohydrates. Feeding experiments were carried out with two human subjects with severe diabetes and with a completely phlorhizinized dog.


Case 1.  —R. P., a man, aged 38 years, first had symptoms of diabetes at the age of 29 years. The disease had run a rapid course, and to the date of the experiments the patient had had a quantitative diet with insulin for seven years. During this time he had been continuously under the observation of Dr. R. T. Woodyatt, and was an intelligent, trained and experienced patient. His usual diet contained carbohydrate 105, protein 127 and fat 183, on which he remained in good health, but not free from morning glycosuria on an insulin dose
