Diabetic nephropathy is a common complication of diabetes mellitus and one of the most important mortality factors for diabetic patients. As the early symptoms of diabetic nephropathy are not obvious, it is usually easy to be ignored, but when swelling, severe proteinuria, hypertension, hypoproteinemia and nephrotic syndrome or uremia appear, most of them are already in the middle and late stage, and the prognosis is mostly poor. Diabetic nephropathy focuses on early diagnosis and treatment. Once diagnosed, in addition to the necessary medication, it is important to pay attention to the diet. This can help reduce the burden on the kidneys, which is beneficial to the control and recovery of the disease, and can also reduce the further damage to the kidneys caused by the prolonged use of drugs. The main dietary aspects are as follows: 1. Control the intake of vegetable protein. Diabetics often use vegetable proteins as supplementary nutrition because they want to control the intake of carbohydrates. Plant protein contains a lot of purine, too much intake will increase the burden on the kidneys, so you should limit the consumption of soybeans, mung beans, soy milk and other high-protein foods, can be replaced by fish, shrimp, sea cucumber and lean meat. 2. Limit fat. When kidney disease appears, the intake of fat should be limited, because fat can cause increased atherosclerosis, kidney disease itself is a manifestation of kidney atherosclerosis. Vegetable oil can be used instead of animal fat, and the daily intake of vegetable oil should be controlled at 60-70 grams or less. 3. Limit the food with high purine. A large amount of purine metabolism in the body will increase the burden on the kidneys. Celery, spinach, peanuts, chicken soup, various meat soups, pork, sardines and animal offal all contain a large amount of purines and should be strictly limited. Lean meat also contains purines, in the consumption of meat can be boiled in water first, abandon the soup to eat. 4. Eat less salt and avoid eating eggs. Kidney disease, such as swelling and hypertension, should limit the amount of salt, the general daily intake of salt to 2-4 grams is appropriate. The protein of eggs will produce more uric acid in the metabolic process. When kidney function is impaired, the end products of nitrogen will accumulate in the body and increase the burden on the kidneys, so when there is renal insufficiency should not eat.
