Evaluation of Low Protein Diet of Patient with Chronic Renal Failure who Used Amino Acid Scale

Abstract

The dietary therapy with a low-protein diet is considered to be effective and useful for the treatment of a chronic renal failure. In this study, we selected and tested 34 cases of outpatients who were on a low-protein diet due to a chronic renal failure. The patients were divided into two groups; either a group of those having low-protein diet food or a group with no low-protein diet food. The aim of this study was to analyze the amino acid compositions generated by the patientsʼ protein intake.

We developed an analysis-method for this study, using the amino acid descending-order scale for a balanced diet. The scale is a frame where the amino acid compositions are indicated in moles for each food combination that satisfies the Japanese dietary reference intakes (amino acid score: 95), and where all amino acids are displayed in descending order starting from the left-hand side.

The study results are as follows: The descending-order scale of the amino acids for a balanced diet was displayed in aminogram format. As a result, it was confirmed that there was no difference in the amino acid compositions generated by the protein intake between the two groups.
