The paper considers current views on rational nutrition in pregnant women with chronic kidney disease. It discusses whether it is expedient to limit protein (to 0.8—0.7 g/kg/day) per day. With decreased renal function, excess dietary protein leads to intraglomerular hypertension and hyperfiltration, elevated concentrations of glycation end products, and metabolic acidosis aggravation; in this case, physiological pregnancy itself induces glomerular hyperfiltration, which in the presence of renal dysfunction may contribute to the rapid progression of chronic kidney disease. Thus, low-protein diet may have nephroprotective effects particularly in patients with hypertension and/or nephrotic syndrome. This diet should include wholesome proteins containing all essential amino acids and may be combined by their additional administration. Attention is drawn to indications for correction of liquid consumption and major minerals (sodium, potassium, phosphorus, and calcium) in patients with chronic kidney disease. The authors declare no conflicts of interest.
