Patients with nephrotic syndrome can eat rice noodles in moderation, while salt restriction, limiting the intake of high-protein and high-fat diets are needed. Nephrotic syndrome refers to the clinical syndrome of massive proteinuria (>3.5g/d), hypoalbuminemia (<30g/L), marked edema and/or hyperlipidemia due to various causes. Patients with nephrotic syndrome are recommended to have a light diet, do not eat too salty food such as pickles, kimchi, etc.; patients are recommended to have 0.8-1.0g of high-quality protein per kilogram of body weight per day, such as fish, lean meat, etc.; patients are also recommended to have a low-fat diet due to hyperlipidaemia to reduce the intake of animal fats and oils, such as fat meat, pork, etc.; patients with significant edema should also have strict control over the intake of water. Rice flour is starchy food, and the protein content of 100g of rice flour is 0.4g and fat content is 0.8mg, which can be consumed in moderation. It is recommended that patients with nephrotic syndrome go to the hospital in time to consult the nephrologist and nutritionist, and have a reasonable diet under the guidance of the doctor.
