Polycystic Kidney Disease Diet

PKD is characterized by the presence of multiple cysts typically in both kidneys; however 17% of cases initially present with observable disease in one kidney, with most cases progressing to bilateral disease in adulthood. The cysts are numerous and are fluid-filled, resulting in massive enlargement of the kidneys. The disease can also damage the liver, pancreas and, in some rare cases, the heart and brain. The two major forms of polycystic kidney disease are distinguished by their patterns of inheritance.
Healthy kidneys regulate levels of potassium and phosphorus in the blood. As kidney function declines, the kidneys are less able to regulate these levels and serum potassium and serum phosphorus levels often become elevated. Nephrologists recommend low-potassium and low-phosphorus diets to offset the high serum levels of these minerals. If you have PKD, your nephrologist can recommend if potassium and phosphorus restriction is needed and how much of these minerals you can safely eat.
High phosphorus foods such as milk, organ meats, beer, chocolate and cola drinks should be avoided if your phosphorus levels are high. Doctors may prescribe phosphorus binders --- a type of drug that binds to the phosphorus and causes its excretion.
Eat foods in season and as close to a home grown state with little processing.
• Locally grown is best.
• Organic is second best.
• Fresh produce is third.
• Frozen is fourth.
• Try to avoid canned, prepared, fried, and microwaved food.
• Avoid foods that are kidney toxins.
