The dietary requirements for nephrotic syndrome are summarized as low-salt, low-fat and limited high-quality protein diet. Why low salt and low fat? Because patients with nephrotic syndrome are certainly associated with a high degree of edema, with water and sodium retention, and if unlimited salt will aggravate edema. In addition, patients with nephrotic syndrome have hyperlipidemia, so the diet should be low-fat and limit fat intake. Limit high quality protein diet, because patients with nephrotic syndrome, the albumin in the blood leaks out a lot through urine, which will lead to hypoproteinemia and need to replenish the albumin, so it is necessary to replenish high quality proteins, such as pure milk, egg whites, fish, these high quality proteins. But the amount of these proteins should not be too much, if the intake of these proteins is too much, it will aggravate the burden on the kidneys, so the amount of quality protein per day should be limited. Roughly, it is one packet of milk and one egg per day, which is more reasonable.
