Effect of Specific Foods, Beverages, and Spices on Amount of Ileostomy Output in Human Subjects

To measure the effect of various selected foods on the amount of ileal excreta, 37 metabolic balance studies were performed on seven subjects who had normal functioning ileostomies for ulcerative colitis. Although this investigation was conducted with the subjects living at home and selecting their own diet, metabolic balance techniques were carefully observed. The diet was identical in the 3-day control and 3-day experimental period except for the alteration of one aspect of the diet in the experimental period. The substances tested were those often either interdicted for or avoided by ileostomates. Only seven (five fruits, one vegetable, and prune juice) of the 37 dietary substances significantly increased the ileal effluent. Excessive water intake, alcohol beverages, fried foods, and spices did not increase ileostomy output. A small but significant loss of sodium and in some instances potassium was observed with prune juice and some fruits that statistically increased ileal output. Although a limited number of foods were studied, application of the results suggests that many dietary substances generally avoided by or interdicted for ileostomates did not significantly increase the amount of ileal excreta when objective measurements are made.
