Abstract
In our past survey of high-phosphate hemodialysis patients, we found that they have a high meat and fat diet and tend to be medicine-dependent, especially the males who take aluminium hydroxide gel and eat as much food, including meat, as they wish. Some had bad effects from taking aluminum hydroxide gel. A large amount of protein in eaten, so it is not easy to reduce the phosphate taken. This time we have selected several low-phosphate foods for the patients. This has had some good effects as follows. In order to determine the effect of the therapy foods, we have examined in hospitals: 10 in the high phosphate group and 9 in the control group. We gave them low phosphate foods (dried egg white, MM-5 Alb-A, white-egg, mashmallow) for two weeks. Confents; Energy 35kcal/kg, protein 1.2-1.5g/kg, phosphate less than 500mg/day, the intake of aluminum hydroxide gel was unchanged. Results: The energy intake was higher during the survey than before the survey in all examinees; the proportion of protein taken (from the food substitution table for kidney diseases) to the total protein was significantly higher in the high phosphate group and the amount of phosphate intake in the group significantly decreased from 700mg to 460mg. The MM-5 was more favored when processed, others were well taken. Controlled phosphate foods were satisfactorily substituted for the usual food. The results obtained show that the phosphate and the Ca×P levels have been lowered, and that there was no remarkable change in alkaline phosphatase, BUN and hematocrit. In the survey where protein intake was increased and low dietary phosphate taken, the phosphate level was lowered even with 1.3g/kg of protein taken.
