Reduced dietary protein intake was shown to ameliorate the proteinuria and thus to reduce the chance for complications and to slow down the progression of kidney failure. These authors speculated that the beneficial effect of soy is due, at least in part, to its lipid-lowering effect which is not shared by animal proteins. This poses a challenge for nutritionists who care for patients with renal insufficiency, since animal proteins are high in methionine and the renal protein-restricted diets, which usually contain animal proteins, provide a relatively large amount of methionine. Renal bone disease and dietary proteins. The phosphorus and the acid loads associated with animal protein diets contribute to the problem.
Dietary phosphorus represents a major challenge for patients with chronic renal disease.
In fact, as the renal function worsens, the ability of the kidneys to excrete phosphorus is progressively lost. Thus, dietary intake of phosphorus inevitably leads to high blood levels of this element and to an imbalance of the calcium-phosphorus equilibrium. This has negative effects on several tissues and organs. Intake of animal protein is inevitably associated with high intake of phosphorus and acid. The compliance with supplemented diet by chronic uremics and their nutritional status.
