Sodium Restriction

“Sodium can contribute to fluid retention and elevated blood pressure. A renal diet emphasises low-sodium options by choosing fresh, whole foods and minimising processed or canned items,” said Ms Usha Joshi, Clinical Nutritionist at Fatima Hospital, Lucknow.

While protein is essential for the body, excessive protein intake can strain the kidneys. A renal diet focuses on consuming moderate amounts of high-quality protein sources, including lean meats, poultry, fish, eggs, and dairy.

Ms Usha Joshi said, “Consume proteins cautiously. It can help protect the kidneys from inflammation, but only if ingested in moderation. Eating more protein in your diet can make your kidneys work harder.”

High levels of phosphorus can lead to bone and heart issues in kidney disease. The renal diet limits phosphorus-rich foods such as dairy, nuts, and processed items. Phosphorus binders may be prescribed to manage levels effectively.

Potassium Management

Impaired kidneys may struggle to regulate potassium levels. A renal diet restricts high-potassium foods like bananas, oranges, tomatoes, and potatoes. Cooking vegetables can reduce their potassium content.

Calcium Intake

Maintaining a balance between calcium and phosphorus is crucial for bone health. The renal diet emphasises low-phosphorus calcium sources like leafy greens and may include calcium supplements if necessary.
