RESUMO

The use of the dietary phosphorus-to-protein ratio (PPR) to reduce dietary phosphorus while maintaining protein intake is valuable for nutritional management in the dialysis population, but the actual PPR values in hospital meals have not been determined. We aimed to determine the accuracy of a nutrient database for estimating the PPR in low-phosphate hospital diets compared with the accuracy of chemical analysis and produce hospital diets with low-phosphate content by boiling meat for 30 minutes before cooking. The phosphorus and protein content of 26 cooked dishes selected from the hospital menu was estimated using a food composition table (FCT) and sent for chemical analysis. Comparisons of FCT-based estimated values with measured values for every 100 g of tested foods revealed an overestimation for the PPR both in plant-based dishes (mean difference ± SD, 4.1 ± 14.6 mg/g, P = 0.06), and in meats (2.1 ± 2.3 mg/g, P = 0.06). By boiling meats, we crafted diets with PPR as low as 8 mg/g. Caution should be exercised in estimating the PPR using a FCT in hospital diets and boiling should be used to prepare hospital meals. Such diets will be promoted for dialysis patients in both inpatient and outpatient settings.

RESUMO

BACKGROUND: Sustained adherence to dietary phosphorus (P) restriction recommendations among hemodialysis patients is questionable. The aim of this study was to evaluate the effectiveness of additional diet education delivered by a dietitian on the control of hyperphosphatemia. METHODS: We conducted an 8-month prospective observational study in hemodialysis patients who had uncontrolled hyperphosphatemia. In the first half of the study (experimental) period, the dialysis nurses and physicians provided the routine dietetic education with the control group (n = 31), while the experimental group (n = 30) received the routine dietetic education plus an additional diet education delivered by dietitians. Both groups received the routine dietetic education in the rest of the study period to test whether the improvement of serum P level was sustained. The primary outcomes were changes in serum P level. RESULTS: At baseline, there was no significant difference in serum P levels between groups (P = 0.27). In the experimental period, monthly serum P levels decreased significantly in both groups (P < 0.001) and the magnitudes of reduction were 1.81 ± 1.46 and 0.94 ± 1.33 mg/dL in the experimental and control groups, respectively (P = 0.02), at the end. The experimental group maintained such improvement for one more month (P = 0.02), but faded out over time. CONCLUSION: Renal diet education guided either by dietitians plus dialysis staffs or dialysis staffs alone reduces serum P level and dietitian-guided diet education provides an additional benefit on controlling hyperphosphatemia in hemodialysis patients.
