Diabetic nephropathy is essentially a complication of the kidneys caused by diabetes, characterized by a history of diabetes for at least five to ten years, with very poor blood sugar control, leading to diabetic nephropathy. The main clinical manifestation is a large amount of proteinuria. Typically, patients will have a large amount of urinary protein, even exceeding 3.5 grams, and some patients may also experience swelling in the lower limbs, among other symptoms. Currently, dietary considerations for diabetic nephropathy mainly include a low-salt, low-fat, high-quality protein diet, and a diabetic diet. Avoid eating foods high in starch, such as potatoes, peanuts, Chinese yam, taro, etc., and also avoid foods high in sugar. Cucumbers, bitter melon, celery, and tomatoes are all good options to consider.
