Diabetic nephropathy diet need to pay attention to: low-salt diet, low-protein diet, low-fat diet and so on. 1. Low-salt diet: Patients with diabetic nephropathy should pay attention to limiting salt intake in daily life, and the amount of sodium intake should be less than 5g per day, because a low-salt diet not only reduces the amount of urinary protein, but also optimizes the efficacy of antihypertensive drugs, such as angiotensin-converting enzyme inhibitors, such as captopril. 2. Low-protein diet: A low-protein diet can reduce the amount of urinary protein and lower the level of toxins in the patient’s body. The amount of protein consumed should be less than 0.8g per kilogram of body weight per day, and the protein consumed should be of high quality, such as milk and eggs. 3. Low-fat diet: It is recommended that patients with diabetic nephropathy adopt the Mediterranean diet structure, which consists of fresh fruits and vegetables, grains and cereals, fish, and olive oil, etc., to reduce the intake of trans fatty acids and saturated fatty acids. Patients with diabetic nephropathy are advised to go to the hospital in time, follow the doctor’s instructions for standardized treatment, and consult a professional doctor for dietary advice if necessary.
