(1) Low-phosphorus diet: This is the dietary principle that patients with renal failure need to follow at ordinary times. Patients should be careful to eat animal offal, chicken soup, ribs soup, bean products and nuts (melon seeds, peanuts, walnuts, pistachios, etc.). ) in peacetime. Excessive intake of phosphorus will cause metabolic disorder of minerals such as calcium and phosphorus, which will lead to secondary hyperparathyroidism, skin itching, renal osteopathy and other complications.

(2) Low-potassium diet: Potassium plays an essential role in maintaining human health. However, due to the obvious decline in the ability of kidney to regulate potassium metabolism in patients with renal failure, it is difficult to maintain the balance of potassium metabolism with the increase of acute endogenous and exogenous potassium load, which leads to hyperkalemia. Therefore, patients with renal failure should be careful to eat foods with high potassium content. Foods high in potassium are: cereals: whole grains, wheat germ; Milk: milk of various flavors; Meat: geese, sardines, poultry, fish and lean meat; Beans: red beans, mung beans and soybeans.

Why should the diet of patients with renal failure pay attention to low phosphorus and low potassium? Patients with renal failure need to pay attention to low phosphorus and potassium, because it can be said that these two elements are not very good for the recovery of the disease.
