Which dietary modification is commonly recommended for kidney disorders?

• A. Low potassium
• B. Low phosphate
• C. Low sodium
• D. Low protein

Answer: (B)

In kidney disorders, managing mineral balance is essential, with phosphate control being a primary focus. When kidney function declines, phosphate isn’t excreted effectively, causing high serum phosphate. Hyperphosphatemia contributes to bone disease and vascular calcifications, so a diet low in phosphate is commonly recommended to help keep phosphorus levels in a safer range. This often means limiting foods high in phosphate and avoiding additives in processed foods; phosphate binders may also be used with meals as prescribed. Potassium restriction and sodium restriction are important in certain situations (for example, to prevent hyperkalemia or edema), but the most consistently emphasized modification across kidney disorders is reducing phosphate intake. Protein restriction is considered in some advanced cases, but phosphate control is the standout, hence the correct choice.
