Nephrotic syndrome is mainly due to increased permeability of the glomerular basement membrane, leading to a syndrome characterized by heavy proteinuria, hypoalbuminemia, hyperlipidemia, and severe edema. The dietary requirements for this disease include low salt, low fat, and high-quality protein diet. Therefore, it is best to use less salt in dishes, and also, one should not drink too much water, as excessive water intake can easily cause sodium and water retention. Additionally, too much sodium can also lead to sodium and water retention and the development of hypertension. Foods rich in fats, fatty meats, and seafood should be avoided, while high-quality proteins generally include lean meats, beef, milk, eggs, etc. Consumption of such high-quality proteins and soy products should be limited.
