IgA nephropathy patients are a very common type of glomerular disease. For IgA nephropathy patients, it is crucial to adhere to a light diet, meaning they should avoid foods such as pickles, salted vegetables, kimchi, cured products, smoked products, and barbecues, focusing primarily on fresh vegetables and fruits. Of course, if IgA nephropathy patients also suffer from renal insufficiency, they must avoid various soy products including tofu, bean sprouts, soybean sprouts, mung bean sprouts, and nut-based foods. These foods contain a lot of plant proteins, which can increase the burden on the kidneys, leading to potential renal insufficiency. Additionally, they should not consume foods high in potassium, such as oranges, bananas, pineapples, etc. Therefore, it is essential for IgA nephropathy patients to be cautious with their diet.
