Which diet for which renal failure: making sense of the options. 
This review describes categories of renal function (normal, renal insufficiency, end-stage renal failure), types of treatment modalities (renal insufficiency management, dialysis, transplantation), and corresponding dietary parameters (protein, energy, fiber, sodium, fluid, potassium, phosphorus, calcium, vitamins, minerals).  The focus is directed toward general and nonrenal specialty practitioners, who are encountering a growing number of geriatric patients and patients who have undergone renal transplantation or are in early renal failure.  The findings indicate that early intervention may delay or prevent rapid progression of renal disease in some patients, that treatment modalities continue to need individualized dietary support to maintain nutritional status, and that transplant goals should include control of obesity and hyperlipidemia to reduce cardiovascular mortality.
