The value of Jerusalem artichokes in the dietetic treatment of persons with diabetes mellitus depends on whether the absence of glycosuria is due to actual absorption and utilization of the carbohydrates or to escape from absorption. A patient of one of us has used large quantities of the dried Jerusalem artichoke in his diet for a number of years, and he volunteered to spend his spring academic vacation of 1926 at the New England Deaconess Hospital, subject to a controlled diet and to various physiologic and chemical observations designed to study this question.
The previous literature with respect to the chemistry and metabolic effect of Jerusalem artichokes and inulin has been reviewed in a recent publication by Root and Baker.1 They gave baked artichokes containing from 31 to 81 Gm. of carbohydrate in six cases and determined the respiratory exchange by the gasometer method, finding a rise in respiratory quotients
