The diet is extremely important for the proper and balanced functioning of the body. Proper selection of the food we consume can help control the accumulation of waste products and fluids in the blood and reduce the burden on the kidneys. Undoubtedly the most important factor for the health and proper function of the kidneys is the intake of sufficient water which ensures that the level of minerals in the urine is not excessively concentrated and helps prevent the formation of kidney stones.

Here are some of the foods that are recommended for the prevention of kidney disease.


Apples are a rich source of pectin and soluble fiber, which maintain healthy cholesterol and blood sugar levels. According to research, pectin also increases the content of important antioxidants in the kidneys and are extremely suitable for their detoxification. Daily consumption of apples reduces the risk of developing urinary tract infections and prevents the formation of kidney stones.


They have powerful antioxidant and anti-inflammatory properties that can benefit kidney health. Increase renal blood flow and improve the ability of the kidneys to filter waste.

Red cranberries

Extremely suitable for urinary tract infections. Prevent bacteria from sticking to the lining of the bladder and kidneys.


A source of vitamin C and vitamin K, as well as many B vitamins. Sauerkraut or cabbage soup enhances the activity of key enzymes involved in the prevention of kidney cancer.


Eggs are a great source of protein, leucine, lutein, zeaxanthin and vitamin D. In people with chronic kidney failure (CKD), it is advisable to consume only protein, as the yolk is rich in phosphorus, a mineral that interferes with kidney function.

Oily fish

Oily fish such as mackerel, salmon, tuna, sardines or anchovies are rich in omega-3 fatty acids. These healthy fats have powerful anti-inflammatory properties and support kidney function. Omega-3s can also help lower blood pressure, which is a risk factor for kidney disease.

Olive oil

In addition to being extremely beneficial, olive oil helps reduce inflammation throughout the body, including the kidneys.

Sweet potato

Sweet potatoes contain vitamins and minerals that balance sodium levels. However, because sweet potatoes are high in potassium, they should be consumed moderately by people with CKD.


With its detoxifying and diuretic properties, beets are recommended for strengthening and cleansing the kidneys, liver and gallbladder.






Poly-cystic kidney disease (PCKD) is a genetically heterogeneous disease that affects the kidneys and other organs. It can exist in both autosomal dominant and recessive forms. Accumulations of fluid-filled sacs called cysts develop in the kidneys, which interfere their ability to filter waste products from the blood. The growth of these cysts leads to enlargement of the kidneys and can also lead to kidney failure.

Autosomal dominant poly-cystic kidney disease is a genetic disease that affects 1 in 1,000 people worldwide and is associated with an increased risk of intracranial aneurysms.

How serious is poly-cystic kidney disease?

The disease can cause serious complications, including high blood pressure and kidney failure. It varies considerably in severity, with some complications preventable. Lifestyle and treatment changes can help reduce the degree of disability.

What causes poly-cystic kidney disease?

The cause of poly-cystic kidney disease is a gene mutation or defect. In most cases, if a child carries such a mutation, it is inherited from a parent. In very rare cases, it develops primarily without either parent carrying the mutated gene. Symptoms include acute low back pain or hematuria due to hemorrhage in the cyst, abdominal discomfort due to increased kidney size or symptoms of uremia.

  • High blood pressure
  • Back or side pain
  • Blood in your urine
  • Feeling of fullness in the abdomen
  • Increased belly size due to enlarged kidneys
  • Headache
  • Kidney stones
  • Kidney failure
  • Urinary tract or kidney infections

In laboratory tests, urine is low in relative weight, proteinuria and hematuria are observed. Peripheral blood count is normal.

Inheritance of a gene mutation can be determined by DNA analysis.
