[Health Channel/Comprehensive Report] Under normal circumstances, phosphorus ions enter the human body through diet, and finally leave the human body through urine and feces. Chen Youcheng, director of the Nephrology Department of Xintai General Hospital, pointed out on the Facebook page "Dr. Chen Youcheng·Kidney Specialist", In the case of chronic kidney disease patients with declining renal function, because the kidneys cannot remove phosphorus in the blood, the blood phosphorus will start to rise. In addition to accelerating the deterioration of chronic kidney disease, it will also cause harm to the cardiovascular system, and share 10 types of high phosphorus foods (Phosphorus ion content>250mg/per 100g of food).

●Whole grains:

brown rice, barley, five-grain rice, oatmeal.

●Processed food:

meat floss, crab sticks, ham, egg tofu.

●Nuts and seeds:

hazelnuts, peanuts, cashews, watermelon seeds.


pork liver, smoked pork liver.


chickpeas, mung beans, red beans, soybeans.

●Dairy products:

cheese (cheese), whole milk powder, skimmed milk powder.


Italian cheese sauce, peanut butter.

●Cakes and snacks:

peanut candy, milk chocolate, black sesame candy.

●Fish and shellfish (dried seafood):

larvae, bonito flakes, frozen scallops, dried small fish.


iron eggs, egg yolks.

Chen Youcheng explained that almost all foods contain phosphorus, especially protein-rich eggs, beans, fish and meat, which are high-phosphorus food sources. In the case of normal kidney function, no matter how much phosphorus is ingested, it can be excreted through urine and try to eliminate as much phosphorus as possible. To achieve homeostasis, but patients with chronic kidney disease eat high-phosphorus food, once blood phosphorus rises, it will do great harm to the human body.

Chen Youcheng pointed out that elevated blood phosphorus in patients with chronic kidney disease will not only accelerate the deterioration of chronic kidney disease, but also cause harm to the cardiovascular system, such as vascular calcification, increased risk of cardiovascular disease, and increased mortality. The combination of calcium in the blood causes hypocalcemia and cramps. Hyperphosphatemia will also continue to stimulate the parathyroid gland to secrete parathyroid hormone, causing secondary hyperparathyroidism, and even parathyroid tumors, itchy skin, and renal bone lesions.

Chen Youcheng reminded that patients with chronic kidney disease and kidney friends must strictly control their diet in order to maintain the blood phosphorus concentration not to be too high. The phosphorus in the diet must be reduced as much as possible to achieve this goal. Careful food selection has become a very important issue.
