If the daily urine volume is greater than 1000 ml and the blood potassium level is normal, it is not necessary to limit the intake of potassium, so you can generally choose vegetables and fruits at will. Because the kidney's excretion of potassium is reduced, if hyperkalemia occurs, it will often cause harm to the body or even life-threatening. Therefore, foods with high potassium content should be appropriately restricted, and the daily level should be lower than1500 ~ 2000 mg. Generally, fruits and vegetables (pumpkin, wax gourd, gourd), apples, pears, pineapples, watermelons and grapes are edible with low potassium content, while foods with high potassium content should be avoided.

In the daily diet, potassium-rich foods mainly include bananas, oranges, oranges, hawthorn, peaches, fresh orange juice, rape, kelp, leeks, tomatoes, mushrooms, spinach, mustard tuber, Sichuan winter vegetables, beans and their products.

In addition, foods with high potassium content can be frozen, soaked in water or discarded to reduce the potassium content.

In order to limit the total amount of protein in diabetic nephropathy, it is generally advocated that protein in daily diet should be given according to the standard weight of 0.6 ~ 0.8 g/kg, and the proportion of high-quality protein should be increased within a limited range.
