2. Patients with creatinine greater than 200 and long-term proteinuria should be treated and nursed back to health as "renal failure". In view of your situation, it is best to add a vegetarian dish such as egg white (the ingredients with high oxalic acid need to be boiled) and use less seasonings and spices, including salt and sugar, and vinegar can be substituted. Egg white can be processed by various methods (steaming, frying, etc.). ), and tea seed oil or sesame oil is recommended as the oil. It is forbidden to eat soy products (but it is not forbidden that black beans and white lentils do not exceed 50g per day), because this substance can regulate endocrine and promote immunity.

3. The total amount of staple food per meal should not exceed 100g (rice, flour, potatoes, miscellaneous grains, starch), and protein foods should be controlled at 100g (meat, fish and poultry) every day.

Finally, I wish the elderly a speedy recovery!
