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.
