Your Guide To A Kidney-Friendly Diet

Kidneys are the work station of your body’s waste-filtration system. When you have a chronic kidney disease or you are on dialysis, your kidneys are no longer functioning as well as they need to. Your doctor may advise you to take a kidney-friendly diet. A kidney-friendly diet modulation will include limiting fluids, eating a low-protein diet, limiting salt, potassium and phosphorous, and consuming enough calories to sustain your body’s energy demands.

A kidney-friendly diet balances protein, sodium, potassium and phosphorous levels in your blood. You will need to limit the amount of protein you eat to help decrease workload of your kidneys. Sodium can elevate blood pressure and worsen kidney function. Healthy kidneys optimally regulate the levels of calcium and phosphorus in your blood. Malfunctioning kidneys don’t filter out enough phosphorus and inhibit calcium absorption, thus increasing the risk of bone diseases and cardiovascular problems. Strike a balance by eating right.


Reduce your protein intake to 0.5 to 0.75 grams per kg body weight. Eat small portions of protein-containing foods and opt for plant-based protein sources like soya nuggets, beans and pulses.


Increase your calorie intake to meet the energy demands of your body. Have frequent small meals packed with breads, grains, sugar and dairy products.


Limit the amount of salt in your diet and avoid packed food with added preservatives and other chemicals.

Calcium and Phosphorus

To limit the amount of phosphorus, keep a watch on your milk and milk products consumption. Foods that are high in phosphorus are dairy products, beans, peas, nuts, and whole grains.


Normal blood levels of potassium help keep your heart rate steady. Dysfunctional kidneys fail to filter out extra potassium that can cause abnormal heart rhythm. Avoid oranges, bananas, tomatoes and raisins.
