Egg Whites May Help Lower Phosphorus
Phosphorus levels declined in dialysis patients who ate egg whites instead of meat for one meal a day.

Twelve patients (92%) had a de-crease in phosphorus, the researchers reported here at the National Kidney Foundation's 2008 Spring Clinical Meetings. Mean phosphorus levels declined significantly from 5.54 mg/dL at baseline to 4.63 mg/dL during the study. Mean patient-reported phosphorus intake also declined significantly, from 692 to 572 mg/day.
The diet did not affect albumin levels, which remained stable at a mean of about 4 mg/dL. Phosphorus binder intake also remained constant; the mean number of pills taken by pa-tients was 6.63 at baseline and 6.42 during the study.
“Pasteurized liquid egg whites are an effective component of the renal diet for lowering serum phosphorus while maintaining the albumin level,” the authors concluded.
