Polycystic Kidney Disease (PKD) is one of the most common inherited diseases,
and most of cases would end up in end-stage renal failure. However, with proper
diet, patients can improve their conditions in a large degree.
Generally, patients with PKD should have a low-fat and high-antioxidant diet.
It is said that plant proteins can help lower the blood pressure and slow the
growth of kidney cysts. Studies show that Omega-3 fatty acids can help reduce
inflammation and slow the progression of PKD as well; it also has
anti-hypertensive and lipid lowering effects.
High-fiber foods, which can combat insulin resistance, are also
recommended—high insulin levels have been linked with heart disease and may
accelerate the progression of PKD. Unlike other kinds of kidney diseases,
patients with PKD require higher levels of potassium.
Foods can be taken by PKD patients:
▲ Soy protein : tofu, miso, tempeh.
▲ Foods that have high omega-3 content: salmon, herring, mackerel ,
anchovies, flaxseed, walnuts, pecans.
▲ High-potassium content foods: papaya, prune juice, honeydew, cantaloupe
melon, banana, raisins, mango, pears, orange, orange juice, sweet potatoes.
▲ High-fiber content foods: spinach, broccoli, cabbage, pomegranate, grains.
Regular consumption of fruits and vegetables is recommended, since they are
excellent sources of vitamins and fiber.
Besides, patients with PKD should also know foods to be avoided. Limit the
intake of animal protein. Excess amounts of salt, caffeine, and alcohol should
also be avoided. Below is a list of a sample of what not to eat.
▼ Foods that have high sodium content: corned beef, instant noodles, potato
chips, cured ham, table salt, preserved foods.
▼ High-protein foods: red meat, chicken, groundnuts, corn, lentils,
chickpeas.
▼ Food that have high sugar content: cola drinks, chocolates, artificial
sugars, powdered juices.
A well balanced Polycystic Kidney Disease diet along with proper exercise,
regular visits to the doctor and compliance of any medical management can help
prevent kidney failure or prevent it from getting worse.
