What is Renal Nutrition?

Did you know Kidneys play an essential role in maintaining the electrolytes of our bodies? They silently perform their function day and night removing and filtering all the waste in the form of urine and removing metabolic waste and toxicity, expelling it out of the body. They produce erythropoietin needed for synthesis of red blood cells and activate vitamin D for absorption of Calcium.

Kidney failure is defined as e GFR <15 which deteriorates the health of the kidneys and its functional ability. What you eat and drink can help slow down chronic kidney disease. Some foods are better for your kidneys than others. Medical nutrition therapy may prevent and delay the onset and slow the progression of CKD. It may help to manage CKD complications. Delaying the need for dialysis for even a few patients can have a great impact.

A healthy eating pattern limits sodium as higher sodium intake is associated with increased blood pressure. This dietary therapy is tailored according to the unique renal issues majorly controlling the key elements such as potassium, phosphorus, and protein. The adoption of a renal-friendly diet can assist individuals in regulating fluid balance, blood pressure, and electrolyte levels, as well as relieving the burden on their kidneys.

What does Chronic Kidney Disease mean?

Chronic kidney disease (CKD) is characterized by a progressive deterioration in kidney function, which occurs gradually over time. This disorder is classified into five separate phases, each reflecting the degree of impairment in kidney function. As chronic kidney disease (CKD) progresses, the renal function of waste filtration and electrolyte regulation gets more impaired.

It is typically a progressive disease it is defined as

  • Reduction of kidney function-defined as an eGFR < 60ml/min/1.73 m2


  • Evidence of kidney damage, including persistent albuminuria-defined as > 30 mg of urine albumin

Risk Factors for Chronic Kidney Disease

Blood Pressure control may slow CKD progression.

  • Limit the sodium to 2300 miligrams

Diabetes Control early may lower CKD risk.

  • Target HbA1c is individualized, based on age, comorbid conditions and frequency of hypoglycemia

Traditional Risk Factors

Non-Traditional Risk Factors

Hypertension Albuminuria
Diabetes Anemia
Dyslipidemia Abnormal metabolism of calcium and phorphorus

Diagnosis of CKD

CKD is detected and monitored by two tests:

  • Estimated glomerular filtration rate (eGFR)
  • Urine albumin -to-creatinine ratio (UACR)

Nutritional Shield: Role of Renal Diet in Preventing Complications

Renal diets also known as Uremic Diets are frequently prescribed by physicians and registered dietitian and nutritionist as a preventative measure with numerous advantages. While it may not eliminate kidney disease, it has a significant impact on risk prevention, disease progression reducing complications and Improving Quality of living.

Who Needs Renal Diet?

  • Individuals with chronic kidney disease
  • People with kidney stone
  • Hypertension (High blood pressure) patients with a diagnosis of end-stage renal disease
  • Diabetic patients with CKD
  • Post-transplant patients
  • Elderly patients with CKD

Nonetheless, potassium accumulation in the blood, a condition known as hyperkalemia, can result from renal disease, making it critical for these individuals to regulate their potassium consumption.

High Potassium food list Low-Potassium food list
Banana Apple
Tomatoes Onion
Beetroot Blueberries
Bran Cereal Eggplant
Orange Cucumber
Spinach Watermelon
Dates Pineapple ( not for diabetics)
Potatoes Peaches
Beans and Nuts Dairy Foods

STEP 6 : Choose foods with less Sodium.

If your blood has excess sodium the damaged kidneys will find it difficult to clear them; this can cause fluid retention and elevated blood pressure. The vigilant monitoring and restriction of sodium intake are critical components of a renal diet.

High Sodium food list Low Sodium food list
Fast food Fish
Olives Unsalted popcorn
Processed Cheese Almonds
