How Bad Is Chocolate for Polycystic Kidney Disease

How Bad Is Chocolate for Polycystic Kidney DiseaseIf you have Polycystic Kidney Disease, the renal dietitian may require you to avoid chocolate. However, this doesn’t mean chocolate itself can cause kidney damage directly. Why PKD patients can’t eat chocolate?

One reason is the high content of oxalate in chocolate

Even though oxalate isn’t harmful for our health in normal condition, it is one substance that PKD patients should stay away from. This is because affected kidneys are unable to remove extra oxalate acid properly that may lead to the formation of kidney stone easily, while kidney stone is just one common complication of Polycystic Kidney Disease.

The second reason is the rich phosphorus in chocolate

In the early stage of kidney disease, kidneys can still eliminate phosphorus effectively. However, with the expansion of kidney cysts, they will replace more and more inherent kidney functioning tissues. When kidney function is less than 29%, extra phosphorus will build up in the blood. In this case, patients should limit their intake of phosphorus-containing foods, so PKD patients should control their chocolate intake.

The third reason is high potassium in chocolate

Just like phosphorus, Polycystic Kidney Disease patients in end stage should also control their potassium intake, and chocolate is just one kind of food rich in potassium. However, in early stage, patients can take in potassium-containing foods relatively, because this mineral can help regulate blood pressure and ease swelling.

As introduced by other nephrologists, chocolate may even affect the growth of kidney cysts like alcohol. According to the above reasons, PKD patients had better stay away from chocolate.
