Dietary precautions for nephrotic syndrome include limiting high protein diet, restricting salt, and not consuming too much animal fat. 1. Limit high protein diet: give normal amount of 0.8-1.0g/(kg-d) of high quality protein (animal protein rich in essential amino acids) diet. Calories should be sufficient and should not be less than 126～147kJ/kg (30～35kcal/kg) per day. Although patients lose a large amount of urinary protein, due to the high protein diet increases glomerular hyperfiltration, aggravates proteinuria and promotes the progression of renal lesions, so it is not advocated that patients consume a high protein diet, and high quality proteins, such as eggs, milk, lean meat, etc. are the mainstay. 2. Salt limitation: excessive salt intake will aggravate edema, low salt (<3g/d) diet should be used. 3. Low fat: in order to reduce hyperlipidemia, diet rich in saturated fatty acids (animal fats and oils) should be reduced, and diet rich in polyunsaturated fatty acids (e.g. vegetable oils, fish oils) and soluble fiber (e.g. oatmeal, rice bran and beans) should be eaten. Patients with nephrotic syndrome should go to the hospital in time for medical consultation to formulate a diet and medication plan under the guidance of a professional physician.
